Sow herbaceous perennials
Perennials such as hollyhock, delphiniums and lupins can be sown directly into drills outside. If space is limited, sow them into pots and place them in a cold frame or by the base of a sheltered wall in filtered sunlight.
Stake tall plants
Stake tall perennials to prevent wind damage to flower spikes.
Watch out for red lily beetle
Inspect lilies for red lily beetle and crush them.
Maximise flowers on roses
Tie in climbing and rambling roses as near to horizontal as possible. This will encourage side shoots to grow along the length of stem, for more flowers.
