This most witty and knowledgeable gentleman
Mr Geoff Ace, has visited us before, and on this welcome return trip spoke about the siting
and construction of rock gardens and water features. Either or both should be established
as the focal point of the view of the garden, rather than the inevitable ubiquitous umbrella
clothes line .
When there is an existing slope, the building of a rock garden is simpler and will appear a
more natural form of landscaping. Firstly the rock must be chosen - Purbeck limestone, for example,
for a chalky soil or Forest of Dean sandstone, perhaps, for our area. One should start
at the bottom and make sure that the stone strata runs parallel throughout the garden,
variation made, to avoid a terraced look, by the change of size, height and distance of the
blocks. These should be dug in sloping gently back to the slope so that the rain does
not erode the soil from the interstices. The whole should resemble a natural miniature
landscape and be backed by appropriate shrubs and planted with carpeting alpines. Maintenance
is easier in a large area if blocks have been spaced deliberately as stepping and sitting stones.
When constructing water features the essential thing, whether for formal or informal ponds,
is to get the level of the edge exactly right. If you don't then the water, which
sets its own level, either leaks out or discloses unsightly concrete or plastic at one end.
Shelves can be incorporated in informal water features, on which may be placed suitable plants
to enhance the natural appearance of the pond - irises for example or marsh marigolds - whilst
more formal effects can be created by using small topiary or phormiums outside geometrical pools.
We were shown each stage of every feature clearly photographed throughout this practical and
entertaining lecture.
