Gardening tips for July

Mid summer and the garden is at its most colourful. The frantic rush of growth has gone and the plants develop into mature shapes and colours. This is the gardening year's peak of achievement.


  • Prune late spring and early summer flowering shrubs immediately after flowering to promote new growth
  • Pick Sweet Peas to increase the flowering season
  • Deadhead Roses and feed regularly
  • Spray Roses to control black spot, mildew and aphids
  • Water hanging baskets and containers at least once a day and feed once a week
  • Feed perennials and shrubs with a granular fertiliser e.g. Rose Plus and hoe into the soil
  • Remove faded flowers on Delphiniums and Lupins. This may encourage a second flowering
  • Trim spring flowering heathers to remove flower heads and to keep in shape
  • Tie in and train new growth on climbing and rambling Roses
  • Water newly planted shrubs and perennials in dry conditions
  • Semi-ripe cuttings can now be taken from shrubs and rooted in a cold frame


  • Check nets on fruit cages to make sure that they have not moved or been damaged

  • Train new growth on trained fruit trees removing side shoots
  • Mulch rhubarb plants and remove flower spikes
  • Remove straw from under strawberries that have finished fruiting
  • Pick raspberries regularly


  • Harvest early potatoes
  • Harvest globe artichokes
  • Earth up main crop potatoes to give an increased yield
  • Keep onions well watered to maximise yield
  • Sow salad crops directly into the ground to continue getting fresh plants

  • Spray Peaches and Nectarines every day with tepid water
  • Use biological control where pests are a problem

  • Soak the floor morning and evening to keep up humidity
  • Remove faded flowers and dropped foliage to prevent the build up of fungal diseases
