Decomposed Granite

gravelThere are some landscape materials I cannot get enough of.  Decomposed granite is a material comprised of pieces of granite 3/8ths of an inch across, and smaller.  The smaller pieces are known as “fines”.  The fines sift down in between the 3/8 inch pieces, and interlock the decomposed granite.  This makes for a surface that delivers that beautiful sound with every step that says garden, dead ahead.  Decomposed granite looks like sand when it is delivered.  I have taken plenty of panic stricken phone calls from clients.  But once it is laid down, graded, compacted and washed, it is a surface that won’t give no matter how high those heels are.  I have no love for asphalt as a surface; does it not seem like a symbol of all those places we have paved over without cause?  Concrete is a great material, as long as it is used with architecture that asks for it.  Concrete aggregate is beautiful for modern or contemporary landscapes-I hate to see it used by a client who really wanted gravel, but was too afraid.  My mentor and dear friend Al Goldner, told me once his only regret as a designer was that he was not bold enough; be bold!  

gravel1Decomposed granite, properly installed, makes for a driveway impervious to tire marks.  In this landscape, the driveway flowed seamlessly into paths for  a vegetable and cutting garden.

gravel2A driveway of decomposed granite requires an expert installation.  GP Enterprises does these drives for me.  They are so careful to install with a careful eye to grade and drainage.  They compact the granite with the same machinery that compacts asphalt. 

gravel42Decomposed granite makes a great mulch for comtemporary landscapes.  This landscape did not ask for mulch-that granite completed a thought. 

gravel5Decomposed granite can finish a formal planting, as well as a contemporary one.  It is clean, fresh, and crisp.  It is easy to make shapes, and moves; it does a great job of giving the eye a place to rest.

gravel7I have done many a terrace in decomposed granite.  It is a clean surface, not so demanding of attention as stone. This garden makes much of the pots and the furniture-the granite is a quietly beautiful  surface. It is the color of nature, a texture that celebrates all that is set on it.

gravel9Wherever people may be in a landscape, I wonder if this surface will play a part. The granite did a great job of featuring the stone from the 1920’s original to this garden. 

Some materials are so versatile, which makes decomposed granite  a major player in my palette of hard surfaces.  Great for driveways, friendly to plants-amazing how it can work in contemporary landscapes as well as vintage ones.

Level

Sometimes level1I am dealt plenty, when I am asked to design for a client. Although the immediate concept of flat ground seems simple, the solutions can be time consuming and messy.  This property was extreme in its high grade- a fence included- on the lot lines.  This home-in a ditch.

level2Can you see-how this client’s land is high at its edges, draining to the house?  There was always soil and bark on the drive after a rain. And water standing next to the foundation, and in the garage.  Sometimes it seems to me that a house is set too low in the ground; this house was a good candidate for a landscape that would improve many conditions-as water is not good for a house.  Slopes are great for sledding or skiing, but not so great for living in.  Flat gound makes for sociable spaces.  I myself have no interest in juggling a glass of wine, and an appetizer on a hill. I like level.  Or As close to level as I can get, and still have drainage. Steeply sloping sites are tough to negotiate, and tough to plant.  If you have a space you wish only to view-plant that hill.  If you plan to live in that space, terrace it.  

level3This clients fence was set a good 40 inches above the grade of their house.  Water rushed down and covered a terrace that was too small for company anyway. I proposed that they tear the entire space to pieces, and put it back together in such a way that would make their outdoor living and entertaining a breeze.

 

level9We got to work building retaining walls some seven feet off the lot line, and flattening the land near the house.  Of course we had to install drainage to handle the water that deluged their property from the adjacent houses. A transformation of this scale is big messy work-they were fine with it. 

level5So many machines, so much stone for the retaining walls, so much mess.

level6Heavy rains interrupted our work.  No drains were in place yet. Looking at all this water, I did explain to my client how they could see all the water on their property, as a layer of grass no longer covered it up. We did a series of drains that took water to the street, and away from the back yard. Its about as much fun to spend money installing drainage as replacing a furnace-only more expensive.  But in this case, the threat of water damage to the house was considerable, and this expense necessary-even if they never went outdoors.

level7This upper level terrace-we planted with columnar carpinus, and Limelight hydrangeas.  This simple planting gave them privacy in a lively way.   A terrace double the size of the original made sure that any amount of entertaining they had a mind to do would be handled adequately by the landscape.  This project was a big fluid mess for better than 3 weeks.  The outcome-level.

Shear Bliss

trimmed1The ability to prune with true precision  is as much about a gift, as it is about the science.   The big science concept has to do with being able to establish a line level with the horizon, or perfectly horizontal-and its complementary-those lines exactly perpendicular to the horizon-or vertical. Mindy’s crew sets lots of vertical markers-the stakes in this pictures.  They use a level to set those stakes exactly vertical.

trimmed2The horizontal plane is determined with a set of lines, or strings.  There will be strings everywhere, side to side.  But there is plenty of gift involved here too.  I perfectly understand the math, but I cannot do this how they do it.   Every cut is made with giant, long handled shears-by hand.  The clip clip takes 7 people, an entire day; its a slow but sure process that I enjoy watching. Even the sound of the clip clip takes my blood pressure down at least 10 points.

trimmed3Shape, mass, and volume are very important design elements in landscape. This landscape is entirely geared to the shape, and level of the lawn plane.  Every other element has been established, based on that plane. The importance of the lawn plane is accentuated by the wide, overscaled  steel edger strip. Where beds and lawn are on the same plane, the edger is invisible; its function is to keep grass out of the planting beds.  In this case, the edging is a design element, clearly indicating a change of level. This very geometric change of level provides lots of interest in a very small space.  The boxwood pruned into long precise rectangles is a great foil to the sprawling shapes of the roses and perennials.

trimmed4Pruning level with the horizon requires attention to a form that may not exist in the space.  The land into which this landscape is planted falls from north to south, and it falls from east to west. To give you an idea of how much drop there is from the south to the north, I measured the height of my Hicks yews.  On the southern most end, they are four feet tall, give or take.  At the east end of the north side, they are nine feet tall; this is a lot of drop.  It was many years, growing those north end yews tall enough to prune. This boxwood is pruned level with the horizon. Pruning with the lay of the land produces an entirely different effect.  Level with the horizon gives a landscape a formal and serene aura.  As in, on even keel, or level-headed.  As my work life is as I have described a big fluid situation, I like the even keel feeling when I am in my garden.  This is a choice any gardener makes when designing.  What do you want from your space?

The Niwashi

niwashi
This time of year I multitask- meaning cocktail hour is also a planting hour.  It takes a long time for me to plant one hour at a time-but I like this arrangement.  I like taking the time to reflect on what I am doing-this is a luxury.  Buck sometimes comes to keep me company, or help out a little .(how amusing to me that he does not like dirt on his hands or raindrops on his glasses; he’d rather walk on top of the low limestone walls than on the grass.)   My architect is urban through and through-but he will help out if I ask;  ask I did yesterday.  One small bed I plant is always rife with wiry maple tree roots; its a headache digging those roots out before I plant.  I managed to talk him into this job, as I had a new tool, a gift from a good friend and client.  Buck cannot resist a new tool, still in its box, that he’s never tried before, so I knew  he’d fall for it.

The Niwashi is an amazing tool.  My friend bought one while on a trip to New Zealand-she says its the only tool she uses in her garden.  She ordered one for me. It has turned out to be such a  fabulous present.  When I saw what fast work Buck was making of a tiresome chore, I had to try it myself.  Obviously I have never gardened with a really sharp tool.  Light, razor sharp, angled perfectly to cut weeds on top or roots underneath the soil surface-where has this tool been all my gardening life? �
niwashi3
I was ready to plant in no time; the Niwashi made it possible for me to plant with my hands.  I vastly prefer this method to using a trowel. So properly prepped soil is a must.  This 4.5 inch tricolor geranium is rooted top to bottom, but not rootbound-perfect to plant. It will transplant easily, and readily take hold.  Though my scheme this year is orange and red violet , I like a little leavening.  This geranium has a gorgeous cream based leaf with hints of my colors. Some variegated foliage is difficult to pair with green leaved plants; not this one.  The orange flower is a modest bonus-but its the leaves I love.  I have seen it called “Skies of Italy”-there’s some romance.�

The driveway bottom bed is planted and watered, as is 1/2 of the top bed, in no time.  Thanks a million, Jane.  For those of you who might want to check out all of their tools, www.niwashi.co.nz.�

Last year’s scheme was entirely dictated by a pair of baby pink fuchsia standards called “Ballerina”. I liked the whole thing just fine.  But what’s not to love about being able to do things differently?
