Harden off and move hanging baskets and containers growing on in the greenhouse into their final position. If your hanging basket plants become leggy, trim off the excess to encourage bushy new growth.
Start to pick sweet peas as soon as they flower to encourage more blooms.
Pinch out the tips of fuchsias to encourage a bushy habit and more flowers.
Lift and divide clumps of snowdrops and bluebells once the leaves start to yellow.
Dead-head your roses if they’re repeat-flowering types. Otherwise, leave the seed heads on for decoration.
Harden off any remaining half-hardy bedding plants ready for planting out.
Dead-head and cut back oriental poppies after flowering. Cutting them close to ground level will stimulate new foliage.
Stake tall perennial plants to prevent wind damage.
Top Tip:
As new shoots grow, use soft ties to train climbing plants such as honeysuckle and clematis to their supports.
