Check all plants, especially newly planted ones, making sure they are moist on a regular basis. Pinch out the growing tips of basket and container plants which will encourage them to produce compact bushy growth with lots of flowers.

Remove faded flowers on early-flowering perennials such as lupins and delphiniums. Early pruning will encourage a second flush of flowers late in the season. Cut the flower-spike down to just above a new shoot or leaf, and give each plant a liquid feed to encourage more fresh growth.
