Small Trees for Fall Color

What trees are small enough to mature in the typical yard space, have low water needs and have full season beauty?

Our Native Vine Maple is Tried and True

Select a new variety of native vine maple, Acer circinatum, like Pacific Fire with scarlet red winter twigs.  It is attractive in partial shade to dappled sun but the best effects of color, both twig and fall leaf color occur in half day sun.  It can be grown in full sun but this will probably spoil the foliage with leaf scorch.  Plant it in morning sun with dappled afternoon shade for best results.  Matures at 15′ to 20′.

Seven Sons Flower is Great for a Tough Spot

Here’s a tree for a hell strip! Seven Sons Flower, or Heptacodium miconioides, is great for full sun and less than great soil.  You can buy it as a standard, or single trunk tree, which will fit in your parking strip nicely. Or buy the low multi-branched form (pictured) for placement in the landscape.  It flowers in late summer and holds the color of the flower into late fall so you don’t miss out on fall color either even it if isn’t the leaves that glow red; 20′ at maturity.

Use Phoenix Snake Bark Maple for Something New

Here is the newest darling tree Acer conspicuum ‘Phoenix’, or Snake Bark Maple.  It needs regular watering, less after a few years have gone by but is not drought tolerant.  Amazing twig color and the bark’s dramatic color show just gets better and better as the tree matures.  Like all maples, plant up on a mound if you have heavy clay soil.  Good drainage is the key to longevity.

Use Crape Myrtle for Four-Season Interest

My favorite Crape Myrtle, or Lagerstromia, is ‘Tuskegee’, maturing at 15′.  These trees need to be planted in well drained soil or up on a mound.  Don’t plant this tree with an east wind exposure.  Best in full sun or 3/4 day sun.  Winter bark, wow fall color, hot red orange summer flowers, with low summer water needs. Another great variety that is easier to find is Tuscarora, or Lagerstroemia indica x fauriei ‘Tuscarora’.

Growing Greens in Winter

It’s the first week of October and I just planted veggie greens starts in my raised bed. Yup it’s not too late. I bought two kinds of collard greens, Bok Choy Rosette (a dwarf variety) and  2 butter leaf lettuce (Rhapsody Butterhead  and Little Gem).  Adding pounds of fresh greens  into my diet this summer has been great for my energy and my waistline.

Each week I pick a mixture of greens.  I wash them in a dab of dish soap and cold water. I spin them dry and stuff them into a large pickle jar. I feel better and  breakfast has been quick and yummy. The smoothies are so tasty! Each morning I scoop out 2 fistfuls of greens, add protein powder, frozen fruit and blend.  It’s so fast, tasty and healthy it’s got to be wrong!  My fav combo is basic greens with basil, frozen peaches, 3 strawberries and 1/2 a banana with coconut milk. The basil and banana are sweet enough I don’t miss adding sugar.  Basic greens could include kale, chard, beet greens or collard greens, romaine lettuce and arugula.

Now that it’s fall, I still have lots of chard and kale left from summer.  My kale is 5’ tall and I have underplanted them with bok choy starts and more kale starts.  I’m not harvesting my kale until after the first frosts hit.  I’m told the kale from this summer will sweeten with the cold and taste even better. Here are the kale varieties I’m growing right now:   Italian heirloom Lacinato, (it’s sometimes called Black Kale) Winterbor, Red Ursa.  I still have lots of rainbow chard and I continue to harvest the largest outside leaves so the plants don’t get huge. They are about 1 foot high at maximum.  If you are a beginner, chard is easy and prolific.

It's amazing how much food you can grow in a 4x8 raised bed.

In addition to smoothies, greens are so great in soups.  I use a pressure cooker to make soup quickly and I pick easy recipes because I’m really not the cook in my family.

My brother is the hot shot cook in our family and I was always outside in the garden with my dad. My favorite recipe is Ethiopian – Inspired Red Lentil Soup.  I’m going to grow my greens and use them  for as long as I can this winter.  If I bought the greens each week at a grocery store it would easily cost $100.00 in a month so I’m saving money too.

3 Colorful Shrubs for Fall

Compact Burning Bush
The most popular variety of Euonymus alata ‘Compacta’ because people think it will be small, say 3′ x 3′.  It is not the least bit small and easily grows into a beautiful small tree.  The smallest variety on the market is called ‘Rudy Haag’ 5′ x 5′.   Even the variety called ‘Pip Squeak’  is 6′ x 5′.  If Burning Bush is not placed with room to grow, these shrubs get turned into ugly muffins by frustrated gardeners.  If it is sheared properly, thinner at the top and wider at the bottom, this can be a very attractive hedge but it will need to be sheared two or three times a year.  Ugh! Too much work for me.

pipsqeck burning bush monrovia 8959268-largeI love to use this shrub as a shree (part shrub, part small tree).  A client of mine, Ruth in Scappoose has hers planted in full sun and pruned into small multi-stem trees.  They are underplanted with a hot orange summer flowering Euphorbia which is a wow combination.  These “shrees” have been in their location for over ten years and they are not irrigated at all. Other than having a professional pruning every year or three, this privacy planting is very low maintenance and simply stunning. The ridged and winged bare stems of the Burning Bush are attractive and add winter interest.  To establish this plant, water it once a week, or twice in hot weather.  Once established, it will thrive with once a week watering.  As it ages in place it needs less and less water.  A plus … The deer don’t bother this plant in Ruth’s garden.

Witch Alder (also called Bottlebrush)
This shrub has two seasons of wow, one is spring where the fragrance is heavenly, the bottle brush flowers are attractive in flower arrangements and if pruned properly, the shape of this “shree” will look good year round.  The 2nd wow is the fall color.

This plant, Fothergilla ‘Mt. Airy’ will need regular water until it has been in place for many years. Almost all plants, even those listed as drought tolerant, look better with some irrigation in our Pacific NW Mediterranean style summer. See fabulous colorful art made from these leaves!!!

Gatsbys Moon Hydrangea

Hydrangea Quercifolia Oakleaf Hydrangea ‘Gatsby’s Moon’ is a new variety from Proven Winners.

Oakleaf Hydrangea 
I’ve written about this plant many times but that’s because it’s so great.  The full size plant may not fit in most landscapes but there are two semi dwarf plants that will.  These plants have huge white conical flowers in mid- summer that fade to a nice pink.  In fall the large and well textured leaf turn the most fabulous rich reds and stay on the plant well past Thanksgiving.  These leaves always go in my Thanksgiving table centerpiece.  Once the leaves fall, there is great rusty exfoliating bark on the stems that glow in the winter light.

Hydrangea quercifolia, Oakleaf Hydrangea ‘Sikes Dwarf’ and ‘Pee Wee’ are the two varieties I use the most. They are NOT tiny shrubs, still expect a 3′ to 4′ wide and tall plant.  My experience is that ‘Sikes Dwarf’ is taller than ‘Pee Wee’.  The leaves are smaller than the species, 4 to 5 inches instead of 8 to 10 inches and they still have the interesting grainy texture and great flowers. One drawback … deer seem to like the leaves.  It is native to the South Eastern United States.

It’s easier to prune than a traditional hydrangea AND it doesn’t need as much water.  If you want you can cut it off at the ground in late winter and start over.  Here is a video “How to Prune Oak Leaf Hydrangea”  by Cass Turnbull of Plant Amnesty.

Protecting plants from winter cold starts in summer

One More Reason to not over water this August.   It will help keep your plants alive this winter.

Plants that don’t get the message to slow down in late summer and fall, don’t go dormant in time for winter cold. Your plant needs dormancy to survive. Start now to protect them before old man winter arrives.

1. Do you over water in August? This is a biggie for a plant tombstone. Overwatering in summer and fall can cause plants to ignore the signals, such as shortened days that tell them to slow down. Try to learn how to water properly.

TIP: A garden coach session could solve this problem for you!

2. Fertilizing plants that don’t need it causes lush growth and can interfere with dormancy.  80% of your plants don’t need any commercial fertilizer at all. The best practice is to place an inch or two of mulch (or compost) around your plants in spring and in early winter …. prior to Thanksgiving is a good time these days with our early freezing temps in the recent past.

3. Severe pruning late in the summer or fall can signal plants to push growth. Signs of tender, new growth in fall or early winter is not a good thing. There are exceptions to this rule of course, nature isn’t fair and makes learning which plants are fine with “whacking” and which are not, takes time, concentration or a good teacher.

4. Plants that are considered drought tolerant are especially sensitive to over watering, fertilizing and severe pruning.  Italian Cypress, Crape Myrtle and rosemary are good examples of plants that can be cold hardy here with knowledge based care.

5. Placement of Zone 7 and 8 plants into areas where the winter east wind will reach them is risky. Plant these evergreens such as large leaf hebes and New Zealand flax plants where the house or other plants will shield them. (Tiny leafed hebes are a better choice anyway). If you are in our East county and can’t shield plants from the winter wind from the Columbia Gorge, consider a different plant palette, plants that do well in Boise (zone 5) come to mind. Small leafed evergreens like dwarf conifers are a great choice. Plants that are deciduous (leaves fall off in winter) are completely dormant and therefore safe from the cold East wind.

Five Important Garden Tips You Need

Weeds and Garden Mulch

Use mulch or even bark dust initially. The first two years in your new landscape are critical for controlling weeds. While installing your new plants, the soil has probably been disturbed and this wakes up dormant seeds causing perhaps hundreds to germinate a a time. If you are diy, cover your soil with 2″ of garden mulch. Mulch is best for your soil and plants but if you have to have low maintenance no matter what, top dress your soil yearly with a dark hemlock bark for the first two years. After you are through the worst of it start applying a garden mulch at least once a year. This mulch will feed your soil and you won’t need fertilizer. 90 percent of plants live happily and healthily with applications of garden mulch and do need commercial fertilizers. There are many exceptions to these rules: SW desert style or xeric plantings like manzanita should not be fertilized or even top dressed with garden mulch ever. Gardenias are fertilizer pigs. Edibles like tomatoes….need fertilizers to produce food.

Get rid of blackberry and ivy

Treating blackberry and ivy with Roundup at the wrong time of year (spring and early summer) is pretty much useless.  In the Pacific NW late summer and early fall is the time when blackberry and ivy are most susceptible to glysophate (Roundup) herbicide. It’s a million times more effective in late summer and early fall.

In an ideal world we would not use herbicides at all;  if you are going to use them, use them sparingly correctly, and at a seasonal time when they will be effective.  For more information see my blog:  Treating blackberry and ivy .  I want acknowledge in light of recent research and court cases, we don’t know the full extent of harm Roundup and other herbicides cause.  It’s still the most practical way to reclaim our native plant areas from the stranglehold of Himalayan black berry and English ivy.  Digging out small areas of blackberries is also effective and better for the health of  mammals and other life forms.

Learn how to water-Watering every day is not your friend

Over watering or under watering new plant material is a typical cause of plant loss. Your common sense watering will kill your plants if you don’t have the specific information for the specific plant type.  You can’t water a new tree the same way you would water your petunias.  I insist my garden coach clients have a written watering plan for the first two years of their new landscape.  I tell them how long to water and to hand check the soil to see if their efforts are successful.  Last, but not least, if you’re watering every day you are in line for losing a lot of new plant material.

Plant labels lie.

Trust me it’s not a conspiracy, but they write the label so that it makes sense for the entire country.  In the Northwest we have the ideal growing conditions so plants will grow taller and wider than indicated.  In addition, just because a plants mature size is 15’ tall, does not mean it will stop growing once it gets there.

Learn light requirements for your plants

It’s not so easy. Labels don’t have enough room to explain the complexities of sunlight, let alone the four different kinds of shade.    Great Plant Picks is a great information resource in many ways, and has an excellent explanation about the different kinds of shade.   There is no perfect solution, even checking the Web will get you four different suggestions for light requirements on a single plant.  This is why experienced gardeners often move plants that don’t seem to thrive in the first location they select.  Others hire designers who know these things first hand.

No hedge pruning unless it’s a hedge

Pruning.  My best advice is don’t let your father-in-law prune your Japanese Maple!  Do not do hedge pruning on plants that are not hedges.  Too much learning already? most of my clients don’t want to become an expert gardener anymore than I want to become a computer technician!! Most just want a healthy and attractive landscape.  In which case, hire someone else to prune for you. While I certainly advocate for hiring a garden coach (since I am one) you can learn from a local nursery, community college or someone who has trees and shrubs that don’t have a bunch of stubs on them.  We want pruning that will enhance a plant’s natural and unique shape. Better yet, contact me to see if I have a real gardener I can refer you to.  Twice a year visits or less to handle pruning will save your trees and shrubs from your good intentions.
