Just starting to think ahead to the summer. Can I ignore all the spring flowering bulbs in containers, in the summer i.e. not water them and pile them on top of each other to save space? eg daffodils, hyacinths, tulips. What about plants like aubretia - do they need to be kept watered? I think I'm correct in saying that azaleas and all the flowering shrubs definitely need watering as towards the end of the summer they will be forming the buds for flowering next spring?
