Save our Tree or Save our Bank

Sunset and Heron Island

The view of Heron Island on the Case Inlet of the Puget Sound.

About ten years ago we built a vacation house on a high banked lot about 75 feet above the beach.  Our house is on, or maybe I should say above the Puget Sound.  The property had a majestic Douglas Fir tree that dominated the property.  Our neighbor adored this tree and we took pains to place the new house so she could still see the tree and the island beyond.  We were not going to be the kind of folks who got an amazing view by taking away someone else’s.  The tree is on the edge of the bank and near our patio. I love to lay under it and watch the clouds fly by.  It’s magical!  That is how it feels to me.

As I look at the tree on a peaceful New Year’s Day and see it now towering over the house and building branches toward and over the roof.  I find myself in the position that many of my clients find themselves in.  Do I bring in a professional to tell me if this trees time is over? If so who do I trust? My time tested arborists in Portland could come up and analyze the tree however, I want someone who knows about slope stabilization in this area.

Our geo-tech has reported that the slope looks good.  He sees it once or twice a year when he and his family go up and use our vacation place.  I can ask him about it but he is not an arborist nor does he specialize in coastal properties.  Should I start to look through the local county government and see if there is some agency that might help me or would that be a bad idea?  They might  start slapping a lot of rules on me forcing me to remove the tree, or pay for a fancy study or say it’s a heritage tree and force me to spend thousands to build up my slope with engineering….just letting my mind run wild here.

When we were building they sent out a junior inspector who declared we had a wet lands on the top of the cliff.  Fortunately I was well aware that the wet land plants that grew there did because the owner of the property had removed all the top soil to create a flat building site to sell.  He left some low spots which encourage winter water to gather there.  Horsetail and similar “grow in anything wet” plants filled in these areas.  I was able to convince them we did NOT have an actual wet lands or need a $15,000.00 wet lands study for my 2.5 acre of cliffside property.

I’m just like my clients once I move outside my area of expertise, I don’t know and I do worry. The advice I give my clients is to get good information.  My first thought is to find a successful landscape designer who specializes in Puget Sound vacation homes. An experienced landscape designer always has an armful of professionals she can refer out.    Hmm so I did find a local landscape designer who gave me her favorite arborist but his web page shows a grinning man cutting into a huge tree trunk with a chain saw.  It’s the first picture and that kind of mentality is what I want to avoid.  My next step will be to call my local professionals and see what they advise or what they would charge to go up and look at it.  Stay tuned……..

 

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’.

Dog Friendly Shade Trees for Landscaping Small Yards

Digging Dog

On the hunt for a cool spot to lay.

Small Shade Trees for Your Dog Friendly Landscaping

It’s hot and dogs are smart.  They want shade and we can provide it or be warned, they may figure out something on their own.  A lot of dogs left to their own devices in a treeless yard will dig a hole under your nice big hydrangea or other shrub and lay in the cool earth in shade.  This may work out just fine for your pet but not your plant!

If you have a big yard you probably have at least one big tree so you have shade.  If you have a small landscape it gets trickier.

Small trees for full sun that provide shade:

Katsura Heronswood Globe suggested for dog friendly landscaping.

Katsura ‘Heronswood Globe’

 

 

Katsura H. Globe has medium sized heart shaped leaves and casts light shade. (Eventually 15′ – 20′.)  I’ve not seen it this big in the Pacific Northwest.

 

 

Lagerstromia natchez suggested for dog friendly landscaping.

Crape Myrtle ‘Natchez’

 

 

This Crape Mrytle has a thick leaf and can cast a heavy shade.  Beautiful flowers, bark and fall color make it a favorite.  (Eventually 20′ tall and wide.)  I’ve not seen it this big in the Pacific Northwest.

 

 

Strawberry tree suggested dog friendly landscaping.

Arbutus Unedo ‘Compacta’

If you select Strawberry Tree Arbutus Unendo ‘Compacta’ be sure to purchase the compact variety.  It is my top choice for heavy cooling shade for a small yard.  I’ve seen this as a 15’x15′ vase shaped tree after ten years.  Please note, too much summer water will kill this durable evergreen.

 

Hydrangea phantom at Normas suggested dog friendly landscaping.

Tree form Hydrangea Paniculata

 

This large shrub/small tree has large leaves and is great for dog shade.  This plant is in Norma B.’s landscape.  It was planted in 2013.  It can be a 15’x15′ tree but typically is kept 10’x10′ with pruning.

Concrete Jungle into Graceful Entry

Can She Do it? Design 2 tiny concrete jungle gardens into unique graceful entries

Putsch  before front yard best pic

For Jeff and Carrie the biggest problem was the builder had planted two Aspen trees.

The Design Challenge     Jeff and Carrie Putsch hired me to create a Landscape Design in a Day for their small backyard. They loved the design and installed it themselves over three years.  Jeff did all the stone work for the patio himself.  Last spring they contacted me to design their tiny front yard in tandem with their next door neighbor.  The front yards were less than 400 square feet and set in a very urban environment.  They wanted their landscapes to flow together.  I thought this was a great idea!

Design Requirements   The clients  wanted plants with low maintenance water needs that could thrive in hot south sun.  They also wanted plants with year-round color/curb appeal.  Evidently, there were many problems to solve.  For Jeff and Carrie the biggest problem was the builder had planted two Aspen trees. Five 10″+ wide trunks erupted from the small Aspen trees.  The roots filled every square inch of the soil = wrong plant in the wrong place!  image004Their neighbor wanted simplicity and color. Happily they had no Aspens, but their soil was also filled with roots of this tenacious tree.

Because the soil was tight hard clay fill, I knew my design solution would include bringing in new soil. Attractive boulders would retain the soil and add a naturalistic style.

The Process  I met with my clients, collected their thoughts and desires and sketched two design options.  Important considerations included:

Tiny Driveways  The driveways were so tiny that there was no place to walk except in the soil side strips.  I used large flagstone so they could step out of their car onto the flagstone.  I repeated the same flagstone for the front walk.

Cars were constantly running over plants at the end of the drive, so we added a strong turf stone and planted it with Stepables.  This softened the look of the turf stone which is rather industrial.  I also selected plants that would grow to hide a large 4×6 metal plate.

Once planted this turf stone will make a safe place for stepable plantings.

Once planted this turf stone will make a safe place for stepable plantings.

Boulders and Soil  Raised rock wall planting beds were designed for each property. Each bed had its own individual shape so they fit together, but had their own style.

While removing the Aspen roots and grading, the contractors discovered there was more concrete and rubble than fill dirt!  It would have been impossible to grow anything without the raised and retained new soil.

Trees:  The Focal Point

"We are very happy with the design and install.  Thanks for all the great ideas!" - Jeff Putsch

“We are very happy with the design and install. Thanks for all the great ideas!” – Jeff Putsch

The focal point trees shape and mature sizes were selected with care so they won’t grow into one another as they age.  The new trees, a Crape Myrtle and an improved Bloodgood Japanese Maple, provided each landscape with individuality.

Teamwork   Since it was such a tricky site, I needed an experienced and creative contractor for the final landscape installation. I met with Donna Burdick of D&J Landscape Contractors and walked through the design and site.  I knew my clients were in good hands.

The Results   Designing both front yards at the same time allowed me to create a landscape that appears larger and cohesive.  Since I always work collaboratively, the clients helped me make each garden unique.  They loved my design and I got kudos for referring Donna Burdick, since her installation made these gardens come together perfectly.

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.
