June
In The Flower Garden This June
Start to pick sweet peas as soon as they flower to encourage more blooms.
Harden off and move hanging baskets and containers growing in the greenhouse into their final position. If your hanging basket plants become leggy, trim off the excess to encourgae bushy new growth.
Check plants daily and water them if the soil is dry, especially newly planted fruit trees and shrubs that are still getting established. To help you save money, time and water, it’s well worth setting up an automated drip irrigation system.
Pinch out the tips of fuchsias to encourage a bushy habit and more flowers.
Continue to thin out drifts of hardy annual plants if they’re overcrowded.
Towards the end of June, if your hardy geraniums have finished flowering, cut them back to encourage new foliage and flowers.
Stake tall perennial plants.
Dead-head your roses if they’re repeat-flowering types. Otherwise, leave the seed heads on for decoration.
Dead-head and cut back oriental poppies after flowering. Cutting them close to ground level will stimulate new foliage.
Top Tip:
As new shoots grow, use soft ties to train climbing plants such as honeysuckle and clematis to their supports.
