'Gravel' or 'Dry Bed' gardening is
another style of gardening that has also gained enormous popularity in the last
two or three years, and ornamental grasses and bamboos not only look good in a gravel or
dry bed garden but are ideally suited. Low maintenance, quick establishment, the self sufficiency of the plants, environmental and climate change
considerations are all benefits that are making this style of gardening so
attractive.
Most species of bamboo and ornamental grasses look fantastic planted in gravel, however
similarly to a Japanese style of gardening less is more. You must leave
sufficient empty space around discretely placed grasses and bamboo plants to show
both grass plants and gravel to their best advantage. Remember that most bamboos do in fact
prefer moist ground and although they will grow quite well in a gravel garden
you must be prepared to water them, if not stick to the ornamental grasses. Recommended bamboos are Phyllostachys Bissettii Phyllostachys Glauca Shibataea Kumasasa,
Sasa Palmatum Sasa vietchi Fargesia Robusta
Gravel gardens are very effective in suppressing weeds, conserving moisture and
showing off your grass plants to their best advantage. If your garden is a hot one,
has a dry micro-climate or is on the coast where steady winds dry both plants
and the soil out, a gravel mulch is ideal for conserving valuable moisture and
also has the advantage that it will stay put and won't blow away like bark mulch.
Easy to grow,
low maintenance, drought tolerant ornamental grasses suited to gravel and dry bed
gardening and their companion plants are among natures most interesting
prospects. Characteristics include adaptations of the foliage, such as a thick,
waxy cuticle, numerous leaf hairs or narrow, strap-like leaves. Tap roots which
can draw up deep soil moisture are another prominent distinction, as are
hummock-forming growth habits. Many bulbous plants survive the dry summer
period by laying dormant during this time. Once established, they require
little attention.
Ornamental grasses are
extremely tough and alongside their drought tolerant companions offer an
amazing and diverse range of shape, colour and seed head to choose from. Recommended
grass varieties for dry and gravel gardens are Miscanthus sinensis'Morning Light, Miscanthus sinensis
''Zebrinus', Molinia caerula 'Karl Foerster', Stipa gigantea and Stipa tenuissima, Pennisetum alopecuroides 'Hamelin
Gravel and dry garden grasses and plants
need little except for full sunlight and good drainage. Gravel grasses and plants adapt to most
conditions and can be grow in a diversity of soil, as long as they are free
draining, and are tolerant a wide range of soil fertility and acidity. Remember
-
Match plants to your soil
type.
-
Fit the size of the plants to the
size of your garden.
-
Improve the drainage by incorporating sand and grit if it is to wet.
-
Unless it is to be a focal point
keep tall plants to the centre or back.
Under the gravel mulch it is important to provide another layer of
weed-suppressing materials in order to avoid your new gravel garden being
invaded by weeds, and particularly to preserve the moisture and low maintenance qualities.
You can use weed suppressing cloth available from your local garden centre,
nursery, or on-line store, layers of newspaper, or cardboard, even better a thick
layer of clean straw or compost covered by newspaper and then weed suppressing
cloth or membrane.
If you are using newspapers you must spread the papers, 6-8 pages or more
thick over the area, leaving spaces for the plants. You can butt the paper up
against the plants the space for weeds is then reduced and the plant will push
out making a bigger hole for itself as it grows.
Although the prospect of a low
maintenance, trouble free prairie garden is attractive the biggest job in
gravel gardening you will face, if you are growing from see, is
controlling weeds during the first two or three years. Grasses in particular
spend the first years of their life developing their complex and evolved roots
system while common ground weeds put all their energy into producing into above
ground growth. That's why we recommended you use good strong pot or
nursery grown plants from the P&G as this is quicker and less labour intensive
solution.
Gravel and dry bed gardens require
only pruning, weeding and a mulch of 5-8 cm (2-3in) of gravel (or even better
compost or straw covered with gravel) will retain a lot of valuable soil
moisture while plants are establishing. Gravel levels can be topped up as and
when required. No spraying, no irrigating and little, if any, fertilizing
saving gravel gardeners loads of dosh and hours of hard work.
By the third year, there is little
for the gavel gardener to do but open a cold one, sit in the middle and enjoy
it!
