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. This may change some once they have been growing for ten years in your landscape, at that time you might be able to experiment with occasional deep slow and long watering.   Then they might become  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 my comments published in this in-depth article from The Digger, July 2020.

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.

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.

Patience in our culture is a revolutionary idea. Contact me if you have more questions on your landscaping.

More Blueberry Heaven: Never-Fail Varieties for Portland Landscapes

Never-Fail Blueberry Varieties for Portland Gardens

A few more thoughts on choosing blueberry plants. Last time we discussed some basics for choosing blueberries. I give you a larger selection to consider and continue to encourage the purchase of big plants.

Here’s a list of blueberries we know will do well in Northwest Oregon and Southwest Washington State—and tickle your taste buds. The listings summarize variety name, maximum height, harvest time and fall color.

Blueberry Varieties for Portland Landscapes

  • Bluecrop, 6 feet, July, red leaf and stems, tall enough for a hedge
  • Spartan, 4 feet, July, hot orange fall color
  • Patriot, 5 feet, early July, hot orange fall color
  • Olympia, 4 feet, late July, light red fall color, tolerates clay
  • Sierra, 8 feet, August, light red winter twigs, great for privacy
  • Sunshine Blue, 3 feet, August, blue-green (evergreen)
  • Bountiful Blue, 3 feet, August, blue-green (evergreen)
  • Liberty, 8 feet, August/September, red-orange, privacy screen
  • Legacy, 6 feet, August/September, hot red-orange

Now that you have information about specific varieties, here are some more hints to help you choose wisely for your garden:

  • Think—and order—ahead. For example, ‘Sierra’ and ‘Liberty’ are still hard to find and might need to be ordered. Contact your favorite nursery in January to inquire about the varieties you want, so they have time to respond or include your request in their orders. Portland Nursery, Farmington Gardens or Cornell Farms will be glad to work with you.
  • Mail order.   One Green World  If you have fallen in love with the flavor of a particular variety of blueberry, be prepared to wait 5 years for a big crop since mail order typically means a small plant.
  • Buy the biggest plants you can afford.   One-gallon plants take too long to yield a decent crop, so splurge if you can and buy bigger plants. I talked with Jim at Portland Nursery about getting big blueberry plants. They get regular shipments of 5-gallon sized plants throughout the year.
  • Blueberry and Dragonfly in Portland Residential Garden - Landscape Design In A Day.Clients wish they had bought bigger plants.  My clients, Jim and Jodi, just bought a home and I completed our second Landscape Design in a Day. Six years ago (at their old house) they bought and planted 1-gallon blueberry plants. Although their then puppy contributed to the stunted growth, by chewing on the canes and peeing on them, he shouldn’t take all the blame. They moved just before they got a great crop. This time they are going to buy big blueberry plants to start with. Remember we are buying time when we buy a bigger plant.
  • Learn basic pruning. Pruning is an important part of being happy with your blueberries (and vice versa). It’s easy, and proper pruning will increase your yield dramatically. There are many good sources for learning the tricks. However, there is no substitute for having someone show you how, putting the pruners in your hands and having you do the pruning. That’s the best way because it sticks in both your mind and muscle-memory.
  • Two Videos.  Here are two videos to help you: OSU Extension Services     University of Maine Cooperative Extension

Yes, getting those berries into your cereal bowl requires time, patience and a bit of training. But, conjure up the fragrance or flavor of a memorable blueberry encounter, and you’ll agree that the effort is worth it. After all, growing blueberries is easy compared to many other fruit plants.

Next time we will look at some of the newest varieties of blueberry. If you are ready to design your Portland garden, contact me to set up an appointment.


Pruning Nandina easily for Portland residential landscapes

Pruning Nandina easily, the perfect low maintenance plant, for Portland residential landscapes

Low Maintenance Shrub (Nandina) for Portland Residential Landscape DesignI promised I would follow up from my last blog about Nandina domestica – Heavenly Bamboo and how seriously low maintenance they are.  I’ll give you my easy pruning trick for Nandina and you’ll be all set to use this shrub, a low maintenance year round beauty, in your Portland landscape.

What’s the problem with shearing Nandina?

If it’s so easy to prune why do we see so many sad looking Nandina out there? People try to prune them like a boxwood hedge.  Boxwoods have a typical shrubs’ woody structure and little tiny leaves.  They can be sheared and look pretty good.  Nandina are a multiple cane plant with a compound leaf composed of many oval shaped leaves.  The best way to ruin their appearance is to shear them into little round balls or squares.

Ugly Nandina in Portland Landscape Need Pruning TipRestore leggy sparse leafed Nandina plants

These photos illustrate embarrassing ugly examples of Nandina out there in commercial and residential landscapes.  These sad plants at my local bank have not been pruned at all.  If yours look this bad, hold off on tossing them.

Portland Landscape Designer's example of poor pruning techniqueWe could correct these ugly leggy Nandinas’ appearance in one year by applying the pruning technique I have illustrated here.  These Nandina domestica ‘Gulfstream’ could look amazing with regular irrigation and pruning once every year or two.

My drawing “Fix Leggy Nandina” illustrates restoring a Nandina that has developed leggy bare canes (or stems if you like).  It has no foliage at the base of the plant.

The Cool Trick to Pruning Nandina

The simplest pruning technique is to cut 1/3rd of the canes to the ground and call it done.  This technique will get you a much better plant once the new canes sprout. I control the height by selecting the tallest canes to remove.

You can take your easy pruning a step farther and select another 1/3rd of the canes and cut them at different heights.  If you only have 3 canes to work with it would look like my “Fix Leggy Nandinas” illustration and in one year it would have a new cane with leaves on it sprouting from the ground and the stem you cut back would have new stem and leaves above where you made the cut.

When to Prune Nandina

You can prune nandina any time of year here in the Pacific Northwest.  I like to remove canes to use for holiday table decoration in the winter but only from a robust plant with lots of canes.  I  prefer to do restorative pruning (such as in my illustration “Fix Leggy Nandina”) as early as March or as late as May.

How to Prune Dwarf Nandina

The technique is mostly the same, but dwarf varieties like ‘Firepower’ need almost no pruning to contain height and if they get enough sun, they rarely get leggy.  The plant can get too wide so I like to thin a few canes out at the bottom (or up to 1/3rd of my canes) every year to keep the plant from ever getting too wide. This allows the little plant to continue serving as a colorful year round foundation plant for the long term in your landscape.     Here is a good video to illustrate pruning the dwarf varieties.

Portland Garden Designer’s Gift Ideas

Here are my favorite items to give as gifts.  The Tilley hat, favorite therapeutic hand cream, inexpensive gloves, Garden Design Magazine, plants as gifts and pruning tools.

The Tilley Hat

You can buy a Tilley hat at REI, Bonnet in NW Portland at Bonnet or on line.  I love my summer (Hemp fabric) Tilley hat because whether it’s picking peaches or playing with my dog, my hat stays on, it’s easy to wash.  I am around a lot of dirt and it is still a cream color. It protects my face from the sun (is recommended by some dermatologists for that purpose) and it’s not too hot to wear in the summer.

Hand Care

http://www.crabtree-evelyn.com/collections/gardeners/60-second-fix-for-hands/Gar-Fix-For-Hands.html

Great Hand Care Product

My favorite hand care product is Evelyn and CrabTree  60 second fix for hands.  It has 2 products, the Ultra Moisturizing Hand Therapy and the 2nd product called Hand Recovery.  There are more heavy duty hand products out there but this one has a light fragrance and penetrates the skin.  It’s therapeutic.  I handle art supplies and  garden so I like a good hand product.  Andalou Naturals Hand Cream is also nice but doesn’t penetrate the skin nearly as well.

Gloves

I love having A LOT of gloves.  I’m a person who misplaces gloves and as a child I resented that nursery rhyme about the kittens who lost their mittens because clearly I was going to be one of those kittens.  I have 20 pairs of inexpensive work gloves.  Gloves are great stocking stuffers.

Plants As Gifts

North Portland Garden Design Itoh PeonyNorth Portland Itoh Peony in Garden Design

Itoh Peonies are so popular this year (2017) that wholesale and retail sources sold out completely. The variety called ‘Cora Louise’ was the most popular and the first to be gone from retail and wholesale sources.   Why are Itoh Peonies special?

They are tough enough for low maintenance landscapes so they are not just for serious gardeners……..and serious gardeners have simply lost their minds over these beautiful and sturdy stemmed plants.  If you have a gardener in your life who loves big colorful flowers……..this gift will express your love for years. A gift certificate to a local retail nursery with a photo would do it. Expect to spend $125 to $150 for a 5 gallon plant.  Here are links to Portland Nursery gift card, Cornell Farm gift card and a video explaining more about Itoh Peonies.

Another popular plant for gardeners that you can buy in December are Hellebores and the big garden nurseries will have these for sale starting in December through March.  These are somewhat toxic so don’t leave them where small children or pets can get them.

Pruning Tools

Pruners –  I love Felco and Corona tools the best.  Cheaper but very lightweight pruners and clippers from Fiskar are popular too.  Here is a good one called PowerGear.  Felcos are for the gardener in your life.  I still love my #6 Felco hand pruner for smaller hands and think they fit most women better than a #2 Felco hand pruner.
