We live in a clay-soil region which means water cannot easily drain away, so I was wondering if a wildlife patch in our garden should begin with a raised 'rockery' area to allow rain water to filter away?
There is a reasonable size garden and we initially want to devote about 10 square metres of it to wildflowers. This patch runs up to a small tree (Acer) on earth with the border of a lawn at its front edge, so the flower garden could run on into a meadow flora arrangement?
But standing water is often a problem, so I thought about founding the wildlife patch on rubble or an elevated region.
Any thoughts please?
