August garden advice and maintenance


General gardening

  • Prune Wisteria back to 6 or 7 buds on long growths
  • Don’t delay summer pruning restricted fruits such as Fans, espaliers and cordons grown against walls and fences.
  • Deadhead flowering plants regularly
  • Don’t forget to water containers, and new plants. Where possible use recycled water or stored rainwater
  • Collect seed from favourite plants
  • Harvest summer vegetables as they become ready
  • Cut any old canes on raspberries, once they have fruited
  • Mow the lawn frequently. You could leave the cuttings on the lawn to provide protective moisture-retentive mulch. Raise the blades on fine lawns to help prevent scalping
  • Deadhead roses to prolong the display into Autumn.
  • Feed roses with a specialist rose fertilizer
  • Deadhead plants such as Dahlia to maintain their displays into Autumn
  • Keep containerised plants well-watered throughout summer
  • Clip evergreen hedges now to give them time to grow new leaves before winter
  • Pick any remaining raspberries then prune the stems down to soil level. Tie in new shoots and remove excess ones
  • Peg down strawberry runners
  • Dead head Sweet Peas to increase the flowering season
  • Water containers twice a day during the hot weather, even if there has been some rain

In the greenhouse

  • Damp down greenhouses on hot days to increase humidity for the plants and control red spider mite
  • Pinch outside shoots on tomatoes and feed with a tomato food regularly
  • Shade plants to prevent scorching. Use netting or shade paint on the outside of your greenhouse

Wildlife gardening

  • Remember to change the water in your bird bath frequently as stale water is unhealthy for the birds
  • Top up bird feeders and put out food on the ground and bird tables
  • Plant marigolds around the vegetable patch to attract hoverflies
  • Watch out for adult frogs and toads leaving the pond
  • Trim hedges less frequently so that wildlife can feed and shelter there
  • Summer meadows may be ready for cutting
