Lawns can be a soothing, oasis of green. However,
lawns can be a water hog and a time usurper (mowing, fertilizing,
weeding). And time is something we all could use a bit more of. And
frankly, if one has a large lawn, why not remove one-third of it and put
it to a better purpose, while reducing water use and increasing free
time?
This was
our goal for 2009. And by Memorial Day weekend of 2010, Mission
Accomplished! Here's what we did, along with a 2012 recap of the successes and failures in that area:
June-July
2009: Kill off 1600 square feet of our 5000 square foot lawn, an
area dominated by every gardener's perennial nemesis, bermudagrass.
Because of the surrounding trees and shrubs, as well as possible
adverse health effects using an herbicide weed killer such as glyphosate
(Roundup), we chose to organically rid ourselves of that lawn, using soil
solarization (complete instructions at that website).
A piece
of advice, learned the hard way: yes, you could purchase a clear
plastic drop cloth from the paint aisle at the big box store, and it
would work...for a couple of weeks. After that, it deteriorates in the
sun to the point where it becomes confetti-like, ripping and flying in
the slightest breeze. Choose a clear plastic that has been treated to
withstand UV rays.
September
2009 (hey, I never claimed to be a fast worker): After much
discussion asking ourselves the question, "now what?", we bring in the
professionals for design ideas. We would choose our own plants; design,
though, is not our strong suit. Landscape Designer Colleen Hamilton from
Bloomin'
Landscape Designs drew up the plan, along with landscape contractor
Dave Rhodes from Rhodes
Landscape Design, who did the installation.
November
2009: The destruction/construction process begins. The crew from
Rhodes Landscaping used a sod cutter to remove the root area of the
bermudagrass. The pathways, brick patio, lighting and garden fountain
are installed.
After the
crews left, we wheelbarrowed in 15 yards of compost, and topped that
with 10 yards of an organic mulch, walk-on bark. And then we wait to see
how the area drains after a heavy rainstorm.
February
2010: Glad we waited before planting. There were a couple of
puddles still standing in the area, 24 hours after several days of heavy
rain. Digging a sump (a deep hole, lined and filled with river rock)
in those two small areas solved that dilemma.
March-April
2010: Retrofit the sprinkler irrigation system, and convert it to a
drip irrigation system. Cap off three of the five sprinkler heads in
the area; convert the remaining two with drip irrigation
adapters. Lay half-inch drip line in the area where we plan to
plant.
April-May
2010: Choose plants! Mostly edible ornamentals. An excellent
resource for this information is Rosalind Creasy,
who has
written several books on the topic. For the blueberries, which required
excellent drainage and very acidic soil, we brought in three cattle
watering troughs, with large holes drilled in the bottoms of the
containers. Several varieties of citrus were planted directly into the
ground. Ground cover along the pool walkway included varieties of
oregano.

June 2010: We watch it
grow, while using a lot less water! Best of all, the bermudagrass
hasn't showed its ugly head...yet. Now, about that patio
furniture...
June 2012 Update: Impressive.This soil solarization project , in combination with the addition of compost and mulch, has mostly thwarted the return of the bermudagrass. On the rare occasion some slinks through to the surface, it pulls up easily.
Biggest mistake of this project...Forgetting to install a drainage system. Oops. The wet winter of 2010-2011 turned the area into a shallow lake, with the mulch threatening to float into the pool. The addition of a sump pump, resting on plywood, kept the mulch in place during rainstorms later in that winter.
So....Rhodes Landscaping returned in December 2011 and installed solid drain pipes that led the water far, far, away. 
And, of course, some plants did not take kindly to this revamped area...specifically, the citrus, which froze to death. A post mortem of the oranges, pummelos and mandarins turned up this interesting fact: that area gets four degrees colder than the garden area just 25 feet away. That was just enough extended cold (22-24 degrees, for four or more hours), to kill off most of the citrus trees. 
We've replaced the dead citrus with some beautiful edible ornamentals that are dormant in the winter, including this Garden Gold miniature peach. The sole surviving citrus, a Centennial kumquat, is on the left side of the picture. Also thumbing it's nose at winter in the kumquat container: the cascading Shock Wave Coral Crush petunia, which survived the cold. 
Oh, and notice the new patio furniture!
