A Front Yard Facelift

30 Aug

By John Curtis – Landscape designer at Dennis’ 7 Dees

Have you ever thought about how to modernize a tired looking front yard?  The same one you have been walking past for so many years and wondering what could be done to freshen it up.  Here is an example of a front yard renovation project that gives a new look to an older style home.

The first goal was to create an updated look to the front entry.  Another was to improve the handicap access of the front walkway.  Because the entire front yard lawn sloped towards the house there was also a seasonal drainage issue that needed to be addressed.  Water would accumulate around the front of the garage and entry during periods of heavy rain.

The design plan called for removal of the dated brick planter and entry walkway.  The brick planter was replaced with a simple soil mound and large boulders.  The brick walkway was replaced with a modern concrete paver pathway which was built up on both sides as it approached the front porch.  This eliminated the steps and created a smooth surface and transition to the front porch that is easy to negotiate.

To solve the drainage issue, a decorative ‘dry creek bed’ was constructed with perforated drain pipe underneath to intercept any seasonal water build up and carry it away from the front of the garage and entry.

The owner had previously taken out some large trees and opened up planting areas that had been mostly shady in the past.  Now these areas had a sunny, southwest, exposure and needed new plantings to fit the change in sunlight conditions  The plantings were designed with a mix of evergreens, seasonal perennials and ornamental grasses to give a long lasting display of colors and interest throughout the spring and summer.

By implementing these landscape improvements, the entire look of this 1950’s ranch style home was successfully updated and the handicap access and drainage issues were effectively resolved.

Breathtaking Water Features

20 Aug

By Drew Snodgrass – Landscape Designer at Dennis’ 7 Dees & one of the original Dees                                                                                                                                                                Ready to tackle a most rewarding landscape improvement? Water features are a breathtaking addition to the landscape but please consider avoiding the pitfalls that create high maintenance and a less than attractive final result.

Designed by Drew Snodgrass of Dennis’ 7 Dees

  1. Plan for success, determine the look you want whether simple or small, such as a column spoutingwater or a waterfall as large and elaborate as you want and have room for.
  2. Verify pump and electrical needs and where best to place and draw power.
  3. Locate the feature and orient it for maximum viewing appeal. My very strong recommendation is to make it safe and easy to maintain.
  4. You should not have to empty your water feature for cleaning. A skimmer vault, bottom drain and bio falls will make maintenance as easy as dumping out a collection bag on a regular basis. Water is drawn to the pump through a recessed collection bag and filter plate where surface debris is collected before it has a chance to settle to the bottom of your pond and decompose. The bottom drain circulates the water, also drawing it through the collection and filter plate in the vault. Algae will still grow on rocks but the water will be clear.
  5. For safety, fence out unwanted visitors as necessary or you can have a very shallow water feature with 1-4” of water while kids are small, but dig the pond as deep as you will ultimately like. Fill with river rock and surface the river rock with pea gravel to the desired depth. Later you can remove rock to the new desired depth as time goes on.
  6. If you want fish, (they’ll feed on the algae),you should allow for 3’ of water depth plus 6” of pea gravel covering the floor. Bridge in hiding places above the pond floor.
  7. Vertical sides will deter raccoons and shelving the sides of the pond makes it easier to stack rock to hide the liner. Keep the look as natural as possible and remember you must hide the liner completely.
  8. If you want water plants plan for them as you build your pond. Buy a pot the size of the plants you want. Research the ideal depth of water for the plant. Set the empty pot where you want the plant and hide all but the top as you rock in the liner.
  9. After cleaning the pond thoroughly, fill it, add de-chlorinator and then add the plants when water PH is ready. Cover the roots with the pea gravel.
  10. Once the water feature is complete you should consider adding lighting. Lighting spillways with underwater lights from the base of falls or from the sides, pointing toward spillways and away from views is important, (See the effect, not the fixture or source).

Although this sounds like a fun DIY project it really is lots of work and the easiest way to do any or all I’ve suggested is call Dennis’ 7 Dees Landscaping, (503)777-7777, get a great design, free estimate and have us install a beautiful and low maintenance end result.

Unique Landscape Design Challenge Results in a Beautiful Outdoor Space

31 Jul

By Jonah Bishop – Landscape Designer at Dennis’ 7 Dees

When I first arrived on this property, I was immediately struck by its unique design challenges. First, the primary view of this yard was from the upper story deck, so I knew it needed to have some elements that would create lots of visual interest from above. Second, I had a homeowner who did not currently spend much time outside in the yard, but wanted to. I knew I was going to have to create some functional space to draw them outdoors. What made this second challenge unique was that almost the entire backyard was sloped away from the house. Now how to tie the two challenges together and come up with a beautiful cohesive design?  I was going to have to get creative!

First, the yard needed some level spaces in which to create usable space. To do this, we needed terraces. However, with this much space the linear footage was going to get boring really fast.  Taking into consideration that we needed an interesting view from above as well, I needed to take a look at the walls and start making them interesting! I got rid of all the straight lines and merged curves and corners to break up long runs of stone. Adding in some planting spaces at half height between the main levels, I was able to use the construction of these to further break up the long runs of stone with different shapes and plants. We now had our level spaces!

Before

Now that we had our level spaces, we needed to make them useable. First we needed steps so that it could be accessible. With the idea already in place of the curving walls, I simply tied in the stairs to flow with the curves of the walls. Now we had access, but to where? We needed a space to draw the homeowner to.

We needed a reason to be outdoors in the new landscape. We needed a functional, livable space. A fireplace was a great element to draw people outdoors, but we needed somewhere to put it. With the way the idea for the walls was flowing, it provided the perfect opportunity to add patio space.

With the terraces, steps, and patios in place all that was left was the plants! Being able to bring in some fun flowering plants was truly the ‘icing’ on the cake for this yard! Now we had a yard that was visually interesting from all perspectives, and functional! Best of all, we created a landscape that the homeowner WANTED to be outdoors in and use!

Making Wishes a Reality

30 Jul

By Spencer Anderson – Landscape Designer at Dennis’ 7 Dees

Have you ever been fed up with your soggy, squishy, muddy lawn and wished that it would just go away?  Have you ever wished that your patio was a little bigger?  Have you ever wished you had a fire pit or a water feature?  These are some of the wishes that the owners of this property had in mind as we went through the design process to change their backyard.  Their landscaping needs changed as their children got older.  Instead of a play structure and swing set they were now looking at having a fire pit and water feature.  Through the design-build process this outgrown landscape was soon transformed into a beautiful outdoor living space by the design-build team here at Dennis’ 7 Dees Landscaping.  Please take a walk through the new landscape starting from the back door just off of the dining room…

Step out onto a roomy paver patio underneath a tall airy cover with skylights that allow the natural light to filter through.  Straight ahead there is a rustic stone fire pit nestled into a stone sitting wall flanked by large sitting boulders creating a perfect place to gather and roast marshmallows on a cool evening.   The sitting wall is also the face of a raised planting bed with trees and shrubs to soften the stone wall and wooden fence.  To the right and across the pavers there is easy access to the side yard and utility area with a wooden gate hide the tools and toys when it’s time to sit back and relax.  To the left the patio extends out from under the cover where one can soak up the sun on a bright day.  Extending the length of the patio is the stone sitting wall that defines the curvilinear patio edge and provides a comfortable enclosure and lots of places to sit.  The sitting wall runs into a three column water feature with water bubbling from all three columns and splashing down on boulders and into the shallow water below creating a soothing sound and a refreshing view from the kitchen window.  Directly below the kitchen window are colorful and fragrant plants.  The patio steps down onto a stone walkway that divides the water feature from a cedar chip play area. A block retaining wall was constructed along the property line to level the play area making it a great place for the family trampoline.  The cedar chip play area exits to a meandering crushed gravel path bordered with rubble rock and lined with plantings full of color and texture.  The path conveniently connects to the front yard through a gate with a decorative arbor overhead.

With the finishing touch of LED landscape lighting to illuminate the key features this backyard landscape was transformed into a beautiful and functional outdoor living environment where wishes were made a reality.  A place where Family and friends will gather often and many fond memories will be made.

I love the outdoors!  Some of my most memorable outdoor experiences came from my childhood as a boy scout in Eastern Oregon.  I recall one such experience where our scout troop hiked 30 miles along the Big Creek Trail near McCall, Idaho.  This was my first long hike so it was a big deal to me.  We camped along the way so I had a pack with all of my provisions that seemed like it was as big and heavy as I was.  The trail was rough and some of the hills were quite steep and challenging, but with every step the beauty of the natural landscape seemed to get more and more breathtaking.  It was this natural beauty and wonder that would push my tired legs to climb the next hill just to catch a glimpse of what was on the other side.  The night we reached our destination I remember sitting around the campfire looking up at the starry night sky wishing that I could always be surrounded by such beauty.  The next morning we were flown out of the forest and back to where we started by a small aviation company.  Looking down from the plane I noticed that the details of the beautiful landscape that I had just seen on my hike were hidden by the tall thick trees.  This experience and many others throughout my life have encouraged me to pursue a career as a landscape designer where I can be an instrument in bringing natural beauty into personal landscapes.  My desire to be a landscape designer combined with a hard work ethic stemming from my experiences working long hours alongside my dedicated father who is a carpenter gave me a great start.  Later I went to school at Brigham Young University-Idaho where I earned a bachelor’s degree in horticulture with an emphasis in landscape design.  Shortly after graduating I started a career with Dennis’ 7 Dees landscaping as a project foreman and quickly transitioned into landscape design.  I love the outdoors and I love being a landscape designer.

Red, White & Blue in a July Garden

28 Jun

By Stacie Palmer – Planscaper at Dennis’ 7 Dees

What, I asked myself, would be a fun, festive combination of plants? Red, white, and blue flowers fit right into the July garden, so what will they be? Why not ‘Lucifer,’ ‘Snowcap,’ and ‘Victoria’? Read on to learn more. . .

RED: Crocosmia ‘Lucifer’ is a perennial that grows from a corm, and is native to Africa. As could be guessed, Crocosmia grow the best in well-draining soil situated in full sun. Making their appearance mid- summer, bright red, tubular flowers are born at the tips of sparse branches, and open from bottom to top. Medium green and sword-like, ‘Lucifer’s’ foliage is pleated, and sits just below the profusion of crimson blooms. Up to 4 feet tall with flower, the habit of this plant is gently arching, making both flower and foliage great bouquet additives. Did I mention how irresistible the flowers of ‘Lucifer’ are to hummingbirds?

WHITE: Leucanthemum x superbum ‘Snowcap’ is a dwarf relative of the old-fashioned favorite, Shasta daisy. This perennial flower loves sun, isn’t picky about soil, and grows quickly. In late spring to summer, single white flowers with yellow eyes drench this plant. It, too, makes a nice cut flower. Because the stature is of a dwarf nature (12”-15” tall and wide on average and in bloom), ‘Snowcap’ withstands wind and rain more hardily than other daisies. What a great addition to the front of any bed—how about edging with a drift of ‘Snowcap’ daisies?! Butterflies adore them, yet rabbits do not.

BLUE: Ceanothus impressus ‘Victoria’ explodes like fireworks into a profusion of blue flowers in spring, then sporadically throughout the summer. Her foliage is dark green, glossy little ovals that are deeply veined and full of texture; what a fabulous backdrop for those flowers! This species of plant is native to Oregon and California, and exhibits tremendous drought tolerance once established. Other attributes include wind and salted air tolerance, as well as resistance to deer browsing. ‘Victoria’ needs fairly ample space in the sun/part sun (she matures on average at 6’-8’ tall and wide), well-drained soil is appreciated, as is protection from winter wind. This is one of the most popular and hardy (zone 7) Ceanothus varieties available in our region. Plant one (or several—great hedge or screen option!) and enjoy the plethora of beneficial insects and pollinators that will feast on the nourishing pollen produced by those incredible indigo blue blossoms! Because this is a plant that is quite tolerant of pruning, why not shape one over an arbor, or into the form of a small tree? What a unique focal point!

Recipe = ‘Victoria’ Ceanothus at the back of the bed, surrounded by a generous helping of ‘Lucifer’ Crocosmia, topped off with an abundance of ‘Snowcap’ Leucanthemum

Landscaping with Northwest Natives

12 Jun

WHY LANDSCAPE WITH NATIVES?

  • Natives are beautiful and provide year-round interest
  • Many are low-maintenance and low-water
  • They help provide habitat for birds, butterflies and other wildlife
  • Planting natives preserves our natural and cultural heritage, and gives our neighborhoods a sense of regional identity.

TIPS FOR DESIGNING WITH NATIVES

  • Match the right plant to the right place
  • Pay attention to the mature size of the plant
  • Choose plants with interest at various times of the year, including bulbs, conifers and winter blooming shrubs.
  • Think in layers: tree canopy, under story plants, ground covers
  • Always be sure to choose nursery grown stock from responsible suppliers.

Need help designing your native plants garden? Planscaper® is landscape design for do-it-yourselfers. Contact your neighborhood Dennis’ 7 Dees garden center for more information.

CARING FOR NATIVES

blechnum spicant – Deer Fern

  • They are ’low-maintenance’ (when planted in an appropriate spot) not ‘no maintenance’.
  • Just like other garden plants, water regularly until established.
  • Mulch to conserve soil moisture and reduce weeds
  • Most natives need no fertilizer
  • Do amend soil with compost
  • Cut back deciduous grasses and perennials in late winter before new growth begins. It’s nice to leave them up over the winter for birds and insects.
