Welcome to the thick of summer, the hottest part of the year. Here are some essential tasks to keep your garden thriving:

cut flowers + nectar flowers

  • Pinch out annuals to encourage bushier growth.
  • Take cuttings of tender perennials.
  • Clear out earlier-flowering biennials and replace them with half-hardy annuals.
  • Thin biennials to promote healthy growth.
  • Cut lavender for drying, choosing newly opened flowers for the best fragrance.
  • Give dahlias a liquid feed, keep them well watered, and tie the shoots of tall varieties to sturdy stakes as they grow.
  • Hoe and hand-weed borders often to prevent weed seeds from spreading.
  • Water and feed sweet peas regularly, picking the flowers every few days, and removing seed pods to prolong flowering.
  • Plant autumn bulbs, such as nerines, colchicums, and sternbergia, in pots and borders.
  • Feed, water, and deadhead summer bedding regularly in pots, borders, and hanging baskets.
  • Cut back early summer perennials, such as hardy geraniums and delphiniums, after flowering for a second flush.
  • Take softwood cuttings from shrubs like pyracantha, hydrangeas, and spiraea.
  • Keep an eye out for pests like lily beetles, snails, aphids, and vine weevils, and remove them to minimise damage.
  • Sow biennials, including foxgloves, honesty, forget-me-nots, and wallflowers, for blooms next year.

Garden Greens

  • Check crops like runner beans regularly for aphids and remove them by rubbing or washing them off.
  • Water thirsty plants such as celery, beans, peas, courgettes, pumpkins, and tomatoes regularly.
  • Make the last pickings of rhubarb and remove any flower spikes that start to form.
  • Thin out heavy crops of apples, pears, and plums, removing any malformed, damaged, or undersized fruits.
  • Sow a last batch of peas and dwarf beans for an autumn harvest.
  • Shorten side shoots growing from the framework of trained fruit trees, leaving about five leaves from their base.
  • Water fruit trees and bushes, then apply a thick mulch of garden compost around their base to retain moisture.
  • Cover brassicas with fine netting to protect them from cabbage white butterflies.
  • Peg down strawberry runners into pots of compost to propagate new plants.
  • Harvest courgettes regularly to prevent them from turning into marrows.
  • Sow small batches of fast-maturing salad leaves, rocket, and radishes every few weeks for continuous harvest.
