We've recently moved from a house with a tiny courtyard garden to a large Edwardian house with a big, if rather overgrown garden. There are large flowerbeds down the sides that are completely choked with weeds - any flowers and shrubs that were once there seem to have been overcome.
While we're reasonably competent at weeding, mowing the lawn, etc., we're utterly clueless when it comes to planning arrangements of new plants to fill the space. I've been reading Lucy Bellamy's "Beautiful and Wild" and would like to follow her approach (planting complementary selections of perennials at different heights). My question is this: can I embark on this even at this time of year - i.e. by selecting and planting out potted perennials that would work for the look I want? And then adding in more as the seasons go by and new plants come into the shops? The book seems to suggest as much, but the instructions seem to suggest doing all the planting in a one-er, ideally much earlier in the year.
Thank you, expert gardeners!
