I bought some small (but larger than plug) perennials from thompson & Morgan. I have put them into larger pots with compost (one pot per plant) and have been trying to grow them on - I keep them in a sheltered decking area and have been covering them at night with polythene cloches. Some of them seem to be thriving but other have died off - any ideas what I have done wrong? I thinking maybe too much water (been trying to keep them damp in the hot spell) or in direct sun for part of the day? All ideas welcome!
