A Guide to Ground Covers
An attractive option to turf, and a solution for areas
where nothing else grows well.
Sometimes, despite all your best efforts, you just can't get grass
to grow in some areas. Maybe it's time to give ground covers a try.
Once established, low-growing perennial plants such as periwinkle,
ivy, stonecrop, thyme, pachysandra and cotoneaster can provide a
lush, natural-looking alternative to turf, and eventually require
very little maintenance. They're great in shady areas, around trees
and on hillsides where lawns can be virtually impossible to
maintain, although most are not tolerant to heavy traffic.
Ground covers are usually more costly to install than grass, so
it's worth making the extra effort to choose the best types for you
area and create a good growing environment for them.
Your garden center can give you advice on these. Usually ground
covers look best when planted in larger, informal groups. Some
types can be planted near each other without fighting for
territory, while others can't. In many cases, lawns and
groundcovers can complement each other nicely... especially when
the planting areas for each are well chosen with regard to
overall shapes, varying soil conditions, light levels, etc. Putting
a detailed garden plan down on paper will help the planning process
a great deal... helping to avoid problems and improve the use of
your plantscaping budget, too.
If the groundcovers are going into an area where some traffic is
likely to occur, give some consideration to laying down a pathway
of interlocking bricks, flagstones or other material. the path can
be informal, following the natural contours of your landscape, or
in a symetrical, straight-line design with borders to complement a
formal garden style. If you're uncertain about which style is best
for your lot, ask your garden centre if a landscape specialist
could stop by your home and provide some recommendations.
While low maintenance is a long-term benefit of most ground covers,
expect to spend the first 2 or 3 years helping the new plantings
fight off
competition from weeds, until they fill in. You'll have to weed by
hand, as commercial herbicides would generally harm the ground
cover as well as the weeds. Mulching around individual groundcover
plants can also help keep weed competition down for the first 2 or
3 years, while giving your plants an opportunity to spread through
root and shoot development.
You should feed new plantings with a high phosphorus fertilizer
like Vigoro Plant Starter until the roots become established, then
switch to a high nitrogen formulation which encourages green growth
(Vigoro Tree and Shrub Fertilizer or Instant Vigoro 30-10-10
Evergreen, Cedar and Shrub Food will work just fine).
Give ground covers a try this year. Down the road, you'll be
rewarded by rich, healthy greens, sprinkled with blue (periwinkle),
white (pachysandra, cotoneaster, lily-of-the-valley), pink
(creeping phlox, stonecrop) and other colourful flowers in the
spring. Summer will bring cool, shade-dappled sweeps of varying
greens. Some, like cotoneaster get red or white berries later in
the season... and many are evergreen, providing year-round
enjoyment.
Whatever kind of ground cover you choose... the result is worth
waiting for. Your extra effort in the early years will be rewarded
with a long-lasting, low maintenance landscape that might be the
envy of the neighbourhood.
