Selecting Dwarf Apple Trees for Small City Landscapes

Recently I specified apple trees for a client with a small yard. I chose ‘Liberty’ for disease resistance and flavor and ‘Akane’.  Along with the name of the apple I wanted, I also specified which dwarfing root stock.  Why should we care about what root stock my apple tree is grafted on?  The first step to success in selecting dwarf apple trees for small city landscapes is picking the right root stock.  I define success as planting fruit trees that stay small but produce lots of fruit and are easy to care for. I picked an EMLA 26 for the ‘Liberty’ and an EMLA27 for the ‘Akane’ which we put into a container.

Dwarf Apple Tree Selection Tip

Please do not buy an apple tree with a tag that only says dwarf.  If the tag does not identify the specific root stock you have no idea how big the tree will be.  Given the small yards most people have these days….not knowing the size your tree will grow to is a mistake that will cause you grief literally as you remove a tree that you cannot manage just when it’s finally producing lots of fruit.

Why Plant Dwarf Apple Trees?

There are many excellent reasons to plant a dwarf apple tree grown on specialized root stock.

  1. Dwarf trees are compact.  If you are a beginner, you probably are in love with having a garden and want everything, all at once. Dwarf trees give you more room for “everything;” because they don’t use much room in the back yard.  Semi dwarf can be 18′ feet tall or more……..that is not small.

    Smaller trees make picking and thinning the fruit easier.  Dwarf trees produce lots of easy-to-reach fruit. This is very important, especially during the first few years, when you thin (pick off) half or more of the immature fruit so your tree can develop the strong wood it needs for a long and fruitful life. Some apple varieties require you pick all the flowers off for a couple of years which would be hard to do on a ladder.

  3. Spraying is easier, too.  When you learn how to spray the tree with a dormant oil, it will be so easy to completely coat the stems and the areas where the buds will break because you will be able to reach them. Check out this Spring Spraying of fruit tree coating a [watch video] tree with a dormant oil spray.
  4. Modern dwarf fruit tree rootstocks help you avoid common problems.  Please, please, please, don’t buy a tree with a label that just says “dwarf apple” or “mini pear” on the label.  The impulsive buy may cause you to miss all the fruits of recent horticultural progress.  Some root stocks in addition to dwarfing the size of the tree, allow your tree to thrive in heavy clay, you won’t get that from a non-specified root stock.  Instead, make sure that it tells you which specific rootstock the tree is grafted to. For example the label could say something like “EMLA 27 creates a 4-to-6-foot tall and wide tree, grows well in containers, tolerates clay soils and is resistant to rot and other diseases.”
  5. Espaliered apple tree in Milwaukie Oregon landscape design.Pruning a smaller tree is physically less work. You won’t even need a ladder.  Brainy Garden has a video on pruning dwarf fruit trees.  Pruning is not a no brainer.  Many sources conflict with each other on how much you should prune…..so best is a class from a local nursery or through the Home Orchard Society.  Not pruning promises that your little trees will rip and tear their branches from the weight of too many apples, so get some help.

Resources for Dwarf Apple Trees

This list of modern rootstocks and their characteristics gives you an idea of  how critical (and cool) it is to select the right root stock for your fruit tree.  I could come up with some more reasons, but you can see how dwarf fruit trees are perfect for how most of us live and garden—in smaller yards with less time but no less plant lust.   RainTree Nursery, One Green World or Burnt Ridge Nursery are three sources for special rootstock apple trees and more.

Rose City Front Yard Landscaping With No Grass

Rose City residential front yard in need of child friendly landscape design.

Rose City Front Yard Landscaping With No Grass

Here is a classic Rose City Portland bungalow with a tiny front yard. My clients Julia and Bruce wanted a welcoming no lawn entry garden. They were planning to raise their family in this home so they wanted a landscape design for the long term. The front yard had difficult, near hostile growing conditions. Large trees to the south blocked sun and used up water and nutrients leaving little for other plants. Julia and Bruce had dealt with the greedy tree roots by installing raised beds for veggies in the front but then their new “Friends of Trees” street trees had grown to the point the veggies were not getting enough sun. The raised beds created a barrier, and made the walk to the front door too narrow. The raised beds had to go.

Landscape Designers Take

Our landscape design needs to solve these problems.

We need welcoming paths and walk that easily accommodate strollers and for extracting children from car seats. There was no path from the driveway to the front walk. They wanted some colorful plants and also winter interest for the front entry. They were ready to lose the raised beds and wanted to have professionals install the new front yard landscape. They wanted low maintenance in the front so they could focus their yard work efforts in the back where they have fruit trees and some edibles.

Julia and Bruce like and enjoy plants and when they have time, they like to play gardener so our planting plan needed to have spark…….but stay low maintenance in the front so they could focus their yard work efforts in the back.

Our plants need to be able to thrive in a hostile environment so the plants needed to be selected by an experienced garden designer. Our new plants will thrive in difficult light, soil full of greedy tree roots and become able to thrive with less water and little maintenance as they mature. The plants also need to be useful to birds, and insects including bees, providing food over a long period of time. Many plants will have color and interest year round and create a view from inside the house looking out the picture window. The current view was a neighbors driveway and a large number of garbage cans.

Unique Light Situation – Hot Shade

While they are not the only Portlanders who have trees blocking light, I want to point out that south facing yards with deciduous shade trees  require thoughtful planting for success. I call it hot shade. There is no morning light. The afternoon light will fall between the leaves of the neighboring trees and the plants will receive dappled light for intermittent periods of time. Late afternoon the front yard will get a blast of direct hot sun for at least an hour before the street trees leaves filter the summer sun into dapples again. The dappled light will support many kinds of plants nutritionally, (remember plants eat sunlight)  but the blast of full sun will toast deep shade plants leaves. There are not enough hours of  light to support full sun plants. Yep not fair!

In between plants for Rose City residential front yard landscape design.Solving This Dilemma

Internet authorities and plant books have lists of plants for shade and sun primarily but there is an entire universe of what I call “between plants”. For this tough little Portland front yard, I selected “shade” plants that I know will take quite a bit of sun. Brunnera ‘Jack Frost’  is one such plant. The first summer its leaves will scorch and so I always tell clients what to expect so they don’t think I’m off my rocker. The second summer there will be less leaf scorch if proper watering occurs. Not every Brunnera variety will tolerate afternoon sun dappled or not but ‘Jack Frost’ will.

Closer to the sidewalk and more sun, I selected (more “between plants'”) full sun plants that I know will tolerate some shade.  They don’t require 10 hours of direct sun to thrive.  Most black eyed Susan (rudbeckia) are listed as full sun plants but I have used them happily in part shade areas. Those dapples of light make enough food for them.  They are a perfect example of a “between plant’.

The sun was more intense and less dappled closer to the sidewalk so I placed the more sun tolerant plants there, including hens and chicks, summer flowering heather (calluna vulgaris) lavender and the strawberry tree. The strawberry tree was planted on a mound to help it thrive because it needs excellent drainage and this is a flat yard, and also to give it a head start from the big trees greedy roots. When the strawberry tree matures, the lavender will have to be removed as there will be too much shade for them at that point.

Portland hardscape path in Rose City residential front yard landscape design.Hardscape

We installed a path to the front walk from the driveway. There were a few muddy small flagstones there before. We actually walked though the motions of unloading a child from a child seat to sell ourselves on the idea of making the path even wider. When the front yard is so small it can seem wrong, or at least sad, to add more hardscape and take away room for plants; but being able to get kids and their accessories out of the car without contortion is a lovely thing.

The landscape contractor, D & J Landscape Contracting, used large flagstone to create this path and it’s so exactly what my clients wanted. It’s quiet beauty and thoughtful placement of each flagstone enhances the entire entry experience.

Potted dogwood for Rose City Portland landscape design.Foundation Planting Trick – Pot up that Red Twig Dogwood

For a little winter drama we planted a red twig dogwood in an attractive pot for the entry pizzazz. There is enough sun (remember those dapples!) to allow the twigs to go a dark red in the winter and have green and cream leaves for spring through summer and a bit of fall color.  If the twigs are in too much shade, there will not be pretty red twigs in winter and that would not produce the drama we want for winter.

Too often these narrow planting beds next to a house have vine maple or other small trees planted in a 36″ wide bed. This turns out badly because soon it will have to be deeply whacked just so people can use the walkway.  This will happen with my red twig dogwood too unless we cheat.

This is one tough plant and a great performer but it is not a forever carefree solution because it will get too big. They will have to remove the shrub/small tree red twig dogwood from the pot every 3 years and whack at least 1/3rd to 1/2 of the roots off or it will crack a glazed ceramic pot. You can plant it in a plastic pot and not have to root prune it.  Then in perhaps 5 to 7 years you will have to cut the pot off the plant, root prune the plant and put it in a new pot.

Strawberry tree focal point in residential Rose City landscape design.The Plants

Arbutus unedo ‘Compacta’   Dwarf Strawberry Tree will become our focal point for the front entry  and our picture window view.

This large shrub or small tree looks wonderful in winter with its red “strawberries” and yes the fruit drop can be a little messy. If you are a neat nik pass on this plant.  My clients loved the color of the bark, color of the berries and are prepared to deal with some fruit drop. Butterflies use this plant for a host so don’t be alarmed if you see a large number of one kind of caterpillar on it. Do nothing and enjoy the show. The berries don’t taste good to people but some birds will eat them if hard pressed.

This tree will have a sinuous cinnamon barked trunk and branches and will become the focal point. Because it is evergreen it will also provide my clients with a view of something other than the  driveway and garbage cans across the street from their picture window. It’s all about the shape of the small tree so I suggest either no pruning or having a pro come and visit every five years. It’s very low water needs and will tolerate the hot sun and reflected heat from the driveway and sidewalk too so it fits our site perfectly.

Portland Landscape Design creates privacy for small city backyard in Woodstock neighborhood

Portland Landscape Design creates privacy for small city backyard in Woodstock neighborhood

Colorful small tree for Woodstock neighborhood backyardCase History:   Portland infill home in Woodstock neighborhood needs a professional landscape design.  The biggest problem for new infill homes with tiny yards is privacy.

Roger and Meghan, no dogs and no kids, had recently moved to Portland and purchased a new home in the Woodstock neighborhood.  Roger wanted an interesting and easy care garden to putz in, colorful plantings and no lawn.  Most of all they wanted privacy.

Solving Privacy Issues-It’s about making a beautiful view

There were bad views on all three sides of the backyard. The house behind had a visually obnoxious roof and we could see their neighbors doing their dishes quite clearly in the evening. The house to the west had a shed which was useful for some privacy, but was infested with Norway rats. The owners were elderly and not keeping up with their home. It’s tough to start making demands of your new neighbors so most of my clients don’t. The house on the other side was also a new infill house and there was no privacy between the two properties.

Portland Residential Landscape Design Woodstock neighborhood before back yard landscape designDesigners Viewpoint on Screening Plants

I needed to create beautiful views to see from inside the house and from the back patio that would simultaneously create privacy and block bad views.  The plants needed to grow quickly but not get too big for the tiny yard.  There are not a lot of plants that will slow down once they are mature.  Most will get too big too quickly.

I selected my trusty clumping bamboo-Fargesia ‘Robusta Campbell’ paired with an evergreen narrow semi dwarf Magnolia tree. The contrast between the feathery bamboo and the magnolia’s large dark green leathery leaves would have been exciting and this would have been a fast-growing solution. My clients decided against the bamboo because rats sometimes eat bamboo shoots and they didn’t want to encourage the rats to come into their yard.  I substituted drought tolerant Boxleaf Tree-Azara Microphyla for the privacy screen and they were back on track.  Azara has a tiny leaf and would contrast well with the Magnolia’s large leaf.

I dropped by the following spring (I was next door creating a design for their neighbors) and saw the magnificent coral orange leaves of Japanese maple ‘Shaina’ with  lime gold ground cover, (Saxifraga) and peach foliage coral bell. The emerging spring foliage puts on an intense and vibrant show.  The new landscape has many seasons of beauty and the spring view is no exception.

Trees for Portland Residential Landscape Design in Woodstock neighborhood

One September afternoon while in Portland’s Woodstock neighborhood I  drove by a former client’s home. My clients had moved, and I was curious to see how the design (installed a dozen years ago) had held up. Once clients move I rarely have continuance with the landscape.  

This drive by is a mixed bag.

Shade Tree for the backyard

Affordable Landscaping Portland design in residential Woodstock.

The shade tree for the back yard is absolutely perfect, and exactly what I had envisioned. This is the part of drive bys I like the best. I used a Japanese Elm – Zelkova serrata variety called ‘Wireless’ because it’s one of the few shade trees that is compatible with lawn and ‘Wireless’ is the perfect shape and size to provide shade for city landscapes.

Their leaves are smaller than most shade trees and allow dapples of sunlight through the canopy to the lawn while filtering out the heat. The exaggerated vase shape of the tree also allows light to come in under the tree in the morning and late afternoon.  This tree provides shade to the south facing deck and the back of the house. It will get over 30’ wide at the top. It matures at 25’ tall so it is a tree that will be wider than it is tall.

If you are a discerning shade aficionado you will say hmmm…… the shade tree doesn’t have low branches so how can you sit on the back deck and have dinner without being blinded by the south sun? We kept a mature mixed hedge at the back of the property and it will block those dinner hour sun rays. The shade tree will filter the hottest sun of the day.

Privacy Screen Planting for side yard

For the design to be functional, the Hornbeam would need to be pruned once or twice a year to become a 10’ narrow wall of thick leaves. The maintenance did not happen since my clients moved.  Now the side yard privacy screen is wildly out of scale and the charm is gone.

Success with Crape Myrtle in Portland Landscape Designs

Residential Landscape Design PortlandLandscaping with Crape Myrtle in Portland

I responded to a request for help from clients in Northeast Portland who were concerned their crape myrtle trees planted two years ago were not healthy because they didn’t flower. They had done their research on crape myrtle but unfortunately not from a source familiar with their trees cultural needs or growth patterns here in the Willamette Valley.

Let me knock a few myths out of the way to save you the same unease and help get our crape myrtle trees off to a good start.

  1. Crape myrtle are drought tolerant so don’t ever water them. Not so!

Latest wisdom is to water them deeply with a drip irrigation or soaker hose once every 10 days. Touch the soil with your hands down a few inches to ensure you are not over watering. It should be moist and then as you get closer to the time to water again it should be almost dry. When they have been growing for ten years in your landscape they might become very low water needs.

I like to design plant companions for the crape myrtle that have the same water needs. In this garden I have crape myrtle with Chinese Camellia – Camellia sasanqua ‘Yuletide’ and American Switch grass-Panicum virgatum ‘Shenendoah’. The clients added ground cover sedum.  None of the plants near the tree need to be watered more than once a week ever after except perhaps for their first summer. A splash of hose water once a week is not at all what I am talking about, I am talking about slowly applied water and preferably drip system or soaker hose.

  1. Fertilize if you want a lot of flowers, that’s true for all plants, right? Not so!

First off, nothing is true for all plants. There are plenty of plants that are harmed by fertilizer so tuck that behind your ear for a future conversation. We typically have fertile soil here in the Willamette Valley, so I would never fertilize crape myrtle beyond adding garden compost to the soil once a year as a top dressing. Adding fertilizer will work against your goal of having flowers.A  young crape myrtle in SE Portland landscaping.

  1. You must dead head (pinch off) all the spent flowers. No way!!

If I had to deadhead crape myrtle flowers, it would take a bazillion hours and eventually a ladder.  Nope, you don’t need to deadhead. When your tree is young, and you get a heavy crop of flowers you might want to thin out some flowers to prevent the young branches from breaking.

  1.  Flower timing will depend on our summer temperatures. True.

It’s got to be hot enough and stay warm even at night to kick off the flowering of crape myrtle here in the Willamette Valley. If we have a cool June which we do sometimes, the flowers will be delayed until it’s been warm enough for long enough. For a deeper dig into crape myrtle read what Paul Bonine says in Pacific Horticulture magazine.  He’s my expert! 

Sleep-Creep-Leap

These clients came from California, a climate where plants grow fast. They were not familiar with the saying “Sleep-Creep-Leap” which describes typical plant growth for the first three years.

A  crape myrtle in the late Portland summer. Photo by Carol LindsayOnce roots are well established many plants grow fast and then after many years, they slow their growth. Just to be perverse, some plants grow slowly when young and then after they are a decade old, they grow much faster. It depends on the genetic makeup of each plant as to its growth rate.  Generally, it takes 3 years of root growth in a plant to get to leap.
