Gardening in July
Featured in the July 2008 handbook.
Pinch out the growing tips of basket and container plants to encourage them to produce bushy even growth and lots of flowers. Encourage chrysanthemum shoots to branch out and carry more blooms by pinching out shoot tips from June to early July. This technique is called stopping.
Biennials, such as Foxgloves, Sweet Williams, Canterbury Bells and Forget-me-Nots, should be sown as soon as fresh seed is available.
Pests and diseases
Use a forceful jet from a garden hose to knock aphids off water lilies and other garden plants.
Spray roses to protect them against problems with mildew, black spot or rust.
Summer bedding plants
Finish planting out summer bedding plants in borders, baskets and containers.
Fill gaps with large Argyranthemums, Fuchsias or Pelargoniums.
Cut down early-flowering perennials
Remove faded flowers on perennials such as lupins and delphiniums. Early pruning often encourages 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 generous liquid feedto encourage fresh growth.
Remove the seed heads from Aquilegia to prevent them from spreading.
