Wild flower patch
Last July I sowed a perennial wild flower patch in a circle approx 20 ft in diameter in a damp area at the bottom of the garden, using seeds specifically for wet, heavy ground. The grass romped away, growing several inches and I left it like that, unsure about cutting it back when it had been planted late in the season. This year, it has continued to grow enthusiastically and the grasses are currently about three ft high and are beginning to fall about. Unfortunately, this means the few flowers are somewhat dwarfed. I realise it's still quite early in the season but I am seeing buttercups, ragged robin and a few daisy-type flowers which are still in bud and there may be more to come. At what stage should I cut the grasses back? I had expected to wait until late summer when the flowers had seeded themselves but wonder if I should do it earlier.
