Larry’s Forest Landscape Letter

Adding a Forest to the Trees

Larry’s new back yard needs a landscape design in Portland, Oregon

My friend Larry bought a property with huge Douglas Fir trees and he wants to create landscape for wildlife in the Pacific Northwest.  He wants a back yard forest.  He sent me a photo of his new property’s back yard after I offered to give him a few tips.

Landscape Designer and Certified Arborist Collaboration

So Larry here’s my advice for your first step;  you will get your back yard forest better, faster and easier with a landscape designer who works with arborists.  Because of all those huge 60′ tall fir trees your next step is to have an arborist evaluate the trees, talk with you and give us a report on the health of your trees.

Why work with an arborist before we create your design?  We don’t want to design your back yard forest landscape around a large existing tree that will need to be removed later.  Such a waste.

 

 

Existing Trees Need Evaluating

Majestic Douglas Fir trees in a Portland landscape

Get an arborist who will consult and evaluate your trees – not just come by for a sales call.  If you have to pay for this service, you will know for sure it is not a sales call.  Some arborists only want to assess whether they can remove or prune any of your trees. It’s true that we want to know if they think any of the trees should be removed or need restorative pruning but we want to know so much more.

Arborist Site Evaluation

Here are a few questions I would ask just from looking at your photo:  I see there is a double gate for vehicles near the trees.  I would wonder if the soil is compacted under your trees because people parked trucks under your trees?

Has excess soil been added over your trees root zone?  Adding soil (or even too much bark chips) over the roots of mature trees could be a problem. Did someone trench near your trees to add a septic or an irrigation system? Do you plan to add a garage or outbuilding near the trees in the future? An arborist can see the problems and advise you on how to mitigate some of the damage done.

General tree care:  get their recommendation on how much to water your Doug firs, and other native trees.  Find out how often and how much water needed, when to start watering each year and when to stop.  Looking on line you will read conflicting information about watering native conifer trees so get your information directly from the arborist.

Stress on Native Trees Due to Climate Change

Dying cedar trees near Portland, Oregon

Ten years ago we never ever summer watered Douglas fir trees.   Due to climate change we have had multiple years of too dry in the spring and even some odd winters where it did not rain enough for our trees.  This has severely stressed many of our native trees. New recommendations I have heard are to give regular but not too frequent deep watering.  Homeowners need a precise watering plan so they know what to do and when to do it.  We want slowly applied water so it gets down deep into the soil rather than run off into a low spot somewhere.  That’s why I favor the drilled emitter tube or a homeowner soaker/ooze type of hose and why I do not recommend using overhead sprinklers for watering anything except lawn.  Ask the arborist how you should water your trees and write it down.  Here’s a money saving tip:  A written report from a certified arborist costs a lot of money and a verbal report is much more affordable.

Fir Tree Compatible Landscape Design

Hey Larry, did you think I would say hire a designer who knows about landscaping with native plants and knows what kind of plants are compatible with Douglas Fir?   I’m a residential landscape designer with 20 plus years in Portland.   I am accustomed to creating designs that are compatible with big trees and that is why I know so many arborists as well.  We create designs that surprise our clients with our downright clever use of space, the way we add functional areas, and create paths that beautifully integrate the entire property.  We take your ideas and make them useable and  brilliant and the plants we suggest will meet your criteria for forest community and low maintenance.

Best Timing for Planting Natives

Don’t Let Your “Do it Now!!!” Energy Add Pressure

And it’s hard to wait. I know you just moved in last fall Larry and now spring is on its way.  You are wanting to get it going right?  If you are not ready to start now say early February with your design and decisions made….. consider getting everything else ready and wait ’til fall for most or all of your plantings.  You will not lose valuable growing time by planting in the fall. Your new trees planted this late spring or (worse in summer) will be stressed by summer heat (even if we do not have a heat dome June 2021) and they won’t grow much. Success will be keeping the leaves or the needles on the tree. Or you could plant the same tree this fall say in October and next spring the fall planted tree will be bigger even though you planted it 5 months later and be less stressed by summer because it has an established root system that grew over winter. So don’t feel you are losing your opportunity for a faster growing tree if you wait ’til fall.

Creating Larry’s Shady Forest One Plant Layer at a Time

Here are some of the plants I’d consider (organized by the layer, tallest, 25′, then 15′, then 7′, then 3′ and under).

So Larry since your existing trees are limbed up (no branches for the first 20’) it’s going to be awhile before you have your shady forest. This means your initial plantings need to be plants that can handle quite a bit of sun now but later on will thrive in dappled shade.

I would design your  hardscape and layout plant first so you know where paths and planting areas will be.  Next up is your planting plan starting with 20′ to 25′ tall under story trees. These trees  will make shade for your forest floor plants.  Cascara frangula purshiana-Cascara buckthorn, Malus fusca-Pacific crabapple, and Amelanchier alnifolia-Pacific Serviceberry are also great bird and pollinator plants.  Native vine maple works too but will have scorched leaves for a few years in this kind of sun.  It will  become accustomed to more sun and then later also thrive in the shade of the big trees.  Situate vine maple so it gets some afternoon shade from those “way up in the air” Doug Fir branches.

Native Oaks are the New Cool Climate Change Trees

Carol Lindsay, Landscape Designer, with Native Oregon White Oak in SE Portland

Our beloved Oregon White Oak grows quickly to 15-20 feet and then slows down as it grows to over 100′ tall.  (Which Larry you and I will not be around to see).   I also love to use  a smaller oak tree, our native evergreen Canyon Live Oak (Q. chrysolepis). While it’s native to southern Oregon it does well in Portland and it is much faster than this southern California small oak called ‘La Siberia’.  Quercus greggi ‘La Siberia’ is very very attractive and tough and available locally at Treephoria.com.  Yes I promised not to go into such detail but I am a sucker for oak trees.

The Next Understory Layer Includes Native Rhododendron

The next layer can be shrubs that grow 10′ to 15’ tall. I tend to call these plants “shrees” as they mature into small trees.

Native Plant Rhododendron Macrophyllum-Pacific Coast Rhododendron

Larry, I know you especially like our native rhododendron which is what started this conversation. So our evergreen Pacific Coast Rhododendron can get 10′-15′ in improved soil.  It can take quite a bit of sun but no boggy wet soil.  When it is older it will also tolerate more shade.

Our very fragrant smaller Rhododendron occidentale-Western Azalea, is listed for sun and loses it’s leaves in winter so not evergreen. The sweet fragrance can waft quite a distance in early spring. I’d plant it on the edge of your forest area where it will always get more sun.  Clients often say its their favorite fragrance.

March: Flowering Currant-Ribes sanguineum

Wildlife Garden Design – Provide for Birds and Pollinators with these Plants

Here are just a few native plants (in the 10′ to 15′ height)  to help you garden for birds:  Ribes sanguineum, Pacific Current, Holodiscus Discolor-Ocean Spray,  and Vaccinium parvifolium-Red Huckleberry.  And you will want  Oemlaria cerasiformis-OsoBerry or Indian plum (which can scorch in full sun so doesn’t look so great in late summer) because it is such an important wildlife plant.  Don’t let its mid summer rough appearance keep it from your landscape.  It’s worth it.  Even this east coast native, Cornus Mas-Cornelian Cherry has very early flowers, low water needs and is so great for pollinators andlater in summer has fruit for birds.

Consider one of the many varieties of Arctostaphylos-manzanita or Ceanothus. These plants should be placed where they will get lots of sun and should not be watered in the summer or fall.  They are great for wildlife providing food for birds including over wintering hummingbirds and important insects.

The Next Layer 5′ to 7′ Native Shrubs

Rubus Parvifolia-Thimble Berry, great for Portland bumble bees

Vaccineum ovatum-Evergreen Huckleberry at a very special garden on Sauvie Island

Native Vaccinium ovatum-evergreen huckleberry is one of my favorites.  It’s shorter in lots of sun and taller in shade so it’s perfect for you. Next on my list would be various native Rubus plants. Rubus spectabilis-Salmon Berry is taller and the flowers are a shocking hot pink in early spring and is beloved by our native bees. Rubus parviflorus – Thimble berry is early season bumble bee food and makes a great 3′ to 4′ high hedge if you want one somewhere.  Both of these plants have short thorns. They take a lot of sun so plant on the edges.  My mom grew up on the Oregon Coast and she loves Thimble Berry to eat fresh.  It’s a little surprise tart ish flavored berry.

Our native salal at 3’ to 5’ can be hard to get established. But don’t get discouraged.  Several of your plants may croak for no reason you can discern but the ones that survive will spread. They will be shorter in the sun and taller in shade, sometimes 5′ tall in shade.  I have a client who makes a gimlet and always adds Salal berry.

Ground Layer Native Plants 1′ to 3’ Tall

Portland native plants: Sword fern with a skirt of dicentra exima-Native Bleeding Heart

Sword fern is a low maintenance native plant for sun or shade and fills planting beds fast

You could plant a bazillion sword ferns and some Gaultheria Shallon-Salal under fir trees and call it done. Polystichum munitum-Sword Fern is good to go in sun or even fairly deep shade. It’s the primary fern in the Willamette Valley so it’s the one I grew up with.  Unlike other native plants (who can be fussy about soil), Sword Fern will grow in horrid clay sub soil as well as the good stuff! They handle fir needle debris as well as leaf load in the fall so you don’t have to spend your time removing every leaf to keep the ferns thriving.  Don’t you want a garden where you can leave the rake in the garage?  Plants that work well with sword fern are numerous but here’s an idea you may not have thought of; let’s use easy to germinate native plant seeds.

Seeds are Perfect for Filling in a New Planting Area Quickly

Native bees rely on this ground cover Phacelia Nemoralis

I love using these native self seeding annuals and perennials to fill in my ground level while waiting for the larger plants to grow. I sow these native plants by seed in fall, in late winter, and in the spring to get them going strong. These are my favs:  Oregon native phacelia nemorosa  for both sun and shade. The California native phacelia  flower is more attractive but is for the sunniest areas along with an Oregon native called Gillia capitata.   After your shade deepens you will have fewer of these last two.  These self seeding native plants provide abundantly for pollinators and they will do a lovely short and long term job of covering your ground. After your larger trees and shrubs get planted these self sowers will fill the spaces left available.

Another plant is Tellima grandiflora-Fringe Cup (which you will recognize Larry from living in Oregon most of your life) and it takes a lot of sun but will settle into shade nicely. It is a perennial and you can buy it as a plant or go for seeds too.

Spread Multi Species Wood Chips To Put Life Into Your Soil

Larry, here’s a cool thing you can do now. Get a load of diverse species wood chips from a tree service. Ask for a mix of different kinds of trees. You want diversity. Spread them at no more than 2” above your existing grade in future planting areas or everywhere for now if your yard is a blank slate.  As the chips break down they will start putting life back into your soil that the trees need. By life I am talking about fungi and making a place for diverse micro organisms. These good bacteria are an important investment in the health of your plants.  Tip:   Only  add  2” of any kind of chip over tree root areas. It has to do with oxygen ratios in the soil and your trees tiny root hairs. Not enough oxygen and the little tiny roots which process most of the water for the tree die off…not good.  When in doubt-check with your arborist about how deep to apply chips around trees.  Many gardeners replenish these chips every few years around their native plants.

The only thing I don’t like about these arborist multi species wood chips is that they are often so chunky that they are hard for some dogs to run on (ankles and knees).  I wouldn’t want these chips to be the only place where dogs can play and run around.

Drought Tolerant Plants for Front Yard Curb Appeal In Portland

Evergreen Ground Cover Plantings for Portland Front Yards

This blog could be called many things…..Drought tolerant Plants for Front Yard Curb appeal in Portland or  Evergreen Groundcovers for Front Yard Curb Appeal but actually it should simply say these plants together are my favorite all season interest groundcover.

Low Water Ground Cover Plants – Heathers with Succulents

I want to introduce a drought tolerant heather that looks fantastic with hens and chicks and talk about how to use these plants for year round good looks in your Portland landscape.

Reasons to use Heather with Succulents or Hens and Chicks

We garden designers want attractive planting combinations to be year round colorful attractive plants that look great together, suppress weeds, feed bees and are simple to care for.  This is my 2nd blog of three showcasing the use of low water and drought tolerant plants.

What is Great About Planting Heathers and Hens and Chicks together?

Shortie Heather  (with Sedums and Red foliaged Hens and Chicks), grow nicely in rock crevices

Contrast!  The fine soft needles of the heather, the large blunt shape of the Sempervivum leaf and the rosette that it forms creates a strong contrast.  Using these combinations really tickles my designer’s fancy.  Using contrast is an important tool for design.

Drought Tolerance:   They both need well drained soil and must be irrigated the first summer to establish mature drought tolerant roots.  So yes plant them together – they are a perfect fit.

Heathers and hens and chicks are evergreen, provide multiple foliage and flower colors to create interest.  It’s fun to see a gold leafed heather with the dark red rosettes of a hen and chick by the front door in winter.  No wonder I love to use them for a colorful year round landscape planting plan.

The Shortie Heathers are My Favorites

Texture galore with drought tolerant evergreen groundcovers including heather, hens and chicks and sedums

Heather and succulents make a tapestry of color in the garden of Marcia Peck on ANLD garden tour.

The shorties – Besides being so attractive these very low (4” tall or less) heather (Calluna vulgaris) are well worth it because they need very little to no pruning at all.  Some clients don’t remember to prune anything so these shorties are just right for them.  All the other types of heather have to be pruned.  I’ve nicknamed these heather ‘shorties’ to set them apart from the many many other kinds of heathers.  If you call them a “shortie heather” at a plant nursery they will not know what you are talking about.  Stick with the latin and look for these at specialty growers and nurseries.  See end of blog for where to buy these special heathers.

I like to use a very short heather with my hens and chicks like this three inch high heather called Calluna vulgaris ‘Mrs. Ronald  Gray’. This heather has needles that grow in a configuration that look like tiny ferns fronds and is my favorite of them all.   Other very short 2 inch to four-inch-tall heathers include Calluna vulgaris ‘Caleb Threkheld’, and ‘White Lawn’.  I use these shortie heathers in a variety of situations with many different kinds of plants but they look especially good with the succulents. They will also drape over a wall nicely.

The Difference Between Drought Tolerant Heather and Other Heathers

The stems look like feathery tiny ferns on this unique Calluna vulgaris, Mrs Ron Green (shortie heather)

I want to be sure my readers will understand that not all heathers are drought tolerant (and most of them are not shorties either).  Heathers named Calluna vulgaris – Scotch Heather (summer and fall flowering heathers) are very different from the spring flowering heathers (Erica carnea and Erica darleyensis) in terms of their soil conditions and water needs.  The Calluna must have well drained soil. They must be watered regularly and carefully their first summer, after that, they prefer less water and can become drought tolerant after just a few years of maturity.   They need full sun or at least 8 hours where Erica carnea can make do with less.  Erica darleyensis can take light shade although I like to grow them in full morning sun.

I Water My ‘White Lawn’ Heather Once a Month in Summer

My Calluna vulgaris ‘White Lawn’ at my vacation house gets watered once a month if its been hotter than usual in the summer.  I’m only there once a month and they even made it through the heat dome of 2021.

Life will be easier, and kinder if you plant your heathers in the fall-best practice.  Planting in early spring would be next best.  Planting in late spring or early summer will mean complete devotion to watering these plants.  It’s easy to kill heather their first summer and here is why – most plants leaves will droop a little and let you know they are dry.  You water them and all is forgiven.

Heathers Cannot Dry Out The First Summer

Not so with heathers – Heather cannot dry out the first summer, not even once or it’s all over.  This is why planting in the fall is easier on you.  If the chance they will have to be replaced come fall is not a problem for you, you have nothing to lose except the plants.  Most of us won’t be planting 50 of these so our loss is minimal except for the shorties which are harder to get in the first place…..still calculate your potential loss and decide if you want to gamble now that you have the facts.

No Pruning for the Shortie Varieties of Calluna Vulgaris – Scotch Heather

Calluna vulgaris – heather freshly pruned at the Oregon Garden. These heathers get about 12″ tall and must be pruned each year.

Taller type heather must be pruned thoughtfully every year but mostly one never needs to prune these shortie Calluna vulgaris – Scotch Heather.  I have plants Calluna vulgaris ‘White Lawn’ that are over 10 years old.  I’ve let one heather spread out and moved any hens and chicks that got in the way.  I have a patch that is over 15 years old and it’s about 24″ wide now.  I like it that wide and I still have room for plenty of hens and chicks.

Drought tolerant Calluna Vulgaris heather in Portland landscape.

My large two foot swath of Calluna vulgaris ‘White Lawn’ gets little to no water at my vacation home. This is what I call a “shortie” heather.

If you are still with your heathers in ten years, you can choose to either referee so the heather doesn’t totally bury the hens and chicks as it matures by carefully pruning out a section of the heather or….You could be a lazy gardener and just let the heathers grow over the top of the hens and chicks since by then you will have lots and lots of the hens and chicks.  I love the combo so I have done a little of both. Just realize that the section you cut out of the heather will not grow back.

Happily hens and chicks are so easy to transplant.  Sometimes I pick little chicks off the mother plant and tuck them into a cooler spot in the ground even with no roots on them at all and often they root and thrive – they are that easy to transplant. Learn more about hens and chicks.

Finding the Shortie Heathers to Buy

So perhaps I’ve convinced you that these shorties heathers are just right for adding full season color and interest to your low water landscape.  Where to buy them?

Highland Heathers – Janice Linewebber can u.p.s. right to your door. If her web site is not updated just e mail her at [email protected]  Ask her if she has any Calluna vulgaris that grows only 3 or 4 inches tall.  She will probably ask if you are my client…I love these little shortie Calluna vulgaris heathers so much in my designs.

Heaths and Heathers is mail order and while there are threats of retirement….so far we can still order from her. She is also on Facebook as Heaths and Heathers Nursery and is in Washington.  Ask her for substitutions as she has some shortie heathers I’ve never grown or used. A shortie is 4″ or under when mature.

There is a large wholesale grower in the area called Little Prince that sometimes grows these heathers. Therefore, I have found them at Cornell Farms and Portland Nursery at times.

Bad News about Slug Bait and Winter Garden Care Tips

Winter is just around the corner here in Portland.   Here are 5 timely tips to help you care for your landscape right now.

Slugs Last chance to knock out slugs! Control your slug population now in late fall.  They lay thousands of eggs that will hatch in spring.  I’ve got bad news about using the so called pet safe slug baits. New science says it kills your earthworms and can sicken your pets and other animals.  Control your slugs with beer traps or even better an instant coffee spray.  Yup coffee! Fill a spray bottle with strong instant coffee or any coffee except de-caf.  Spray the leaves of plants they prefer and any slugs or snails you see.

I grow lots of winter greens here in NW Portland so I’ve been out there spraying down the leaves of my beautiful Dinosaur Kale plants to protect them now.  Spraying coffee once a week in fall and early winter makes a big difference in the spring hatch of slugs.   Read more about why slug bait harms worms.

Portland garden tips include coffee

Its the caffeine that kills slugs or snails. Instant coffee works well.

Mulch.  If you only do one thing to improve your soil and care for your plants, mulching is the biggie.  Schedule your winter mulch application for the last week of November to mid-December or hire someone to blow in your mulch.  Companies such as Bark Blowers will blow in mulch including the newer “living” mulch products that I prefer.  One company that provides mulch inoculated with beneficial bacteria is Natures Needs, a product called  Recology Compost.  McFarlane Bark, Mt Scott Fuel and Grimms Fuel supply basic mulch products.   Did you mulch just 2 inches deep?  Great!  Now go and unbury the crowns of your plants so they don’t die from rot during our wet winter. Burying plants with mulch might be a good practice in Vermont or Montana but not here.

Protect your plants from winter temperatures

The best cold protection for plants in the winter isn’t something that naturally occurs to most people.  Over watering and over fertilizing done in summer can cause plants to not go dormant.  When cold weather comes, they are not prepared.  Read more: Protecting Plants from Winter Cold Starts in Summer 

Pruning knowledge  There are many plants that should not be cut back in the fall and winter.  There are many perennials and grasses that can be cut back to create a more attractive winter landscape. This is a case by case basis which drives new gardeners crazy. Consider consulting with your garden designer who can teach you what to do to your plants and when.  It feels good when you know what to do.

Protect your pottery  The best winter protection for your pottery is proper drainage and location.  Make sure water drains through the pots hole and doesn’t back up.  If water sits in the bottom and it freezes, good bye pot.  I have had Vietnamese high fired pottery outside and intact for over 15 years.  I always put drainage material in the bottom of the pot and a piece of flagstone under the pot or I use those little pottery feet.

If I have expensive pots where they will get east winter wind, the kind of wind that freezes rain to ice on the power line, I would move them into a protected area for winter right now. I hate to even think about that kind of weather but we get our share here in Portland Oregon, especially in January.   Its hard to pay attention to the weather report, and besides who wants to move heavy pots around when its icy cold out?  Not me.

Lawn Do Over for Portland Landscapes

Drought Tolerant, Synthetic & No Lawns Landscaping

Landscape Design in a Day's newly installed drought tolerant RTF grass.

Landscape Design in a Day’s newly installed RTF grass with dry stream bed.

This is the year for rethinking the lawn. As a Portland landscape designer many of my new clients want to make big changes in their landscapes.  I am recommending clients replace their old lawns with new and improved grass varieties.

My Lake Oswego clients, George and Marcia, contacted me completely discouraged about their front yard. I met them in the fall after our particularly hot and horrid summer of 2015. They had spent their entire summer watering and watering their lawn.  It wasn’t dead on the October day that I came to their home but as you can see it was quite unattractive.

Damaged Lake Oswego lawn

They decided it was time to hire a designer and start over with their landscape. It is a typical Lake Oswego landscape with heavy clay soil, fir trees nearby with thirsty roots, and drainage problems.

Before we even started the landscape design process, I was able to share information about a new lawn grass that uses less water and is more durable than the grass (perennial rye grass blends) we have been using for the last 30 years.  Working closely with Kevin Schindler of Autumn Leaf Landscaping Inc. we replaced their old lawn with Rhizomatous Tall Fescue (RTF) grass and designed a naturalistic dry stream bed that also solves the drainage problems.  Solving the drainage problems also enhances the health of the grass.  Even RTF grass doesn’t do well in a boggy winter soil.  George and Marcia are very pleased with the appearance and performance of the new grass.  They love their new dry stream bed and how it has pulled together the entire front yard, giving it a dramatic focal point.

They are no longer slaves to watering with drought tolerant lawn.

Installation day at George and Marcia’s Lake Oswego home.

This year several of my clients have taken out their old grass and installed RTF.   From a distance it looks like any lawn, in fact it looks more uniform because it grows so thickly that it tends to crowd out weed grasses much better than our perennial rye grass does.  My Lake Oswego clients especially appreciate the fact that RTF tolerates more sun and heat and if they did decide to let it go dormant, it will come back beautifully.  RTF can even handle a south facing lawn with reflected heat from a sidewalk.  This is the most difficult place to successfully grow grass so Portland landscape professionals are embracing this new product.

It is available as a roll out turf product (sod) and as seed.  Kuenzi Turf & Nursery

Other clients want no lawn designs, thinking it will be lower maintenance.  No lawn will mean lower water usage but replacing a lawn with paths and plants does not promise low maintenance. Even the fairly new minimalist style using 90% round river rock and 10% plants isn’t as low maintenance as you think. Someone has to blow dust and debris out of the river rock frequently to prevent weeds from building up.  Many clients simply don’t want to mow any lawn and are fine with the first two years of extensive weeding that is needed to get a no lawn front yard established.  For a lot of people, however, weeding is the least favorite gardening chore.

Synthetic Lawn Installed in front yard for drought tolerant landscaping.

Newly installed synthetic lawn in Parkrose Heights neighborhood

Other clients are installing synthetic lawn.  Before you sneer at the idea of fake grass (which I did when I first heard about it), check out these photos of my Southeast Portland clients Bob and Norma Bleid.  They gave themselves a retirement gift, front and back synthetic lawn.  No water, no chemicals, no fertilizer; it is the ultimate low maintenance landscape lawn.

Early fall is a particularly good time to install a new lawn or landscape.  With a good irrigation system landscapes can be installed any time of the year.  As a Portland landscape designer I am not fond of July or August installations, I know my clients will be “nervous nellys”  seeing their plants’ leaves droop, scorch and burn in the summer sun.  The fall rains typically do a beautiful job of providing the moisture needed to get plants (including grass) well established.  This eliminates the stress and worry of summer planting.

Summer Heather – Perfect for year round color

Summer flowering heather can be easy care

I use heather at my vacation house because it’s so easy.  I’m there once a month, have no irrigation system and I have hungry deer.  It’s got to be a tough plant to make it!  Lots of people buy heather, plant them and they die quickly.  Without knowledge specific to heathers, success is tenuous, but with a little knowledge this is a very tough drought tolerant winner of a plant in my book.  It has year-round beauty, is great food for bees and it can be the evergreen plant that holds a summer garden together visually through the winter.

Planting Tips:

Honey bee on spring heather in Sellwood Moreland garden designHeathers need good drainage but if you have clay soil don’t despair.  Heathers planted on a burmed planting bed or  on a low mound do well.  Heathers are perfect for  sunny slopes.

A designer pal plants her heathers in pure barkdust.  I’ve done this and had excellent results as long as it was on a slope or berm.  Don’t try this crazy bark dust idea in a flat landscape with heavy clay unless you berm up.

Watering well the first year is critical.  If heather plants dry out to the point of  wilting, even just a little bit, they will die.  There is no rescuing it with water and having it “perk up” as many other plants will do.   When the tiny fine foliage wilts or dries the plant stops taking in water with its roots.  Avoid this first year problem and take advantage of the benefits of a fall planting.  You still have to water carefully the first summer after a fall planting but it is not so edgy.

Pruning Tips:

Pruning is important and easy.  The most important year for pruning is the second spring after you have planted the plant.  Prune before new growth starts.  You must trim to just above the previous years wood; trim too much and you will have ugly holes in your plants that may never fill in.  Avoid pruning late in fall or winter.

Calluna -Summer Flowering Heather

Trim too little or not at all and  in a few years you will have an ugly plant with bare wood stems in the center of the plant.  When this happens we can’t simply cut it back severely which we can do with many plants to fix the problem.  Trimming every year before new growth starts (February or March for Pacific Northwest) will keep your plants attractive long term.  Who knew low maintenance was so much work right?  Once you know what to do, you have a plant that will work beautifully for decades with a once a year trim.  That is low maintenance.

Summer heather/Calluna Vulgaris is a great plant for hot sun situations.  This summer for the first time ever, I actually had foliage burn.  They got no water for 45 days in record breaking heat, but since these plants have been there for five years there was not permanent damage or loss.  New plants would not tolerate that amount of drought but mature plants took my neglect in stride.  6 months later there was no sign of any damage.  My kind of plant!
