August can be the hottest, driest month of the year, but it can also be humid with heavy rain storms. This fluctuating weather can cause plants stress and create the perfect conditions for fungal diseases to take hold. Don’t allow plants to dry out and mulch after watering to conserve moisture. While garden borders enter a lull at this time of year, the vegetable garden and greenhouse should be at peak production. It’s also time to sow seeds for spring crops and to plan for autumn.

 

Planning:

  • Order spring-flowering bulbs to be planted in the autumn.
  • Harvest and dry herbs so that you can use them during the winter months.
  • Take cuttings of tender perennials such as pelargoniums and salvias.

In the garden:

  • Sow winter hardy crops such as spinach and lettuce varieties such as ‘Winter Density’.
  • Sow hardy annuals such as love-in-a-mist, ammi, larkspur and cerinthe. They will germinate, then overwinter, before shooting away in spring to provide you with an early display of flowers.
  • Pot up strawberry runners. Snip away the stem attaching them to the parent plant and replant in a new strawberry bed.
  • Prune rambling roses.
  • Cut back wildflower meadows using a scythe or strimmer. Remove the trimmings so that they don’t rot down and fertilise the soil, as wildflowers need nutrient poor soil.
  • Trim hedges to create well-defined shapes that will provide structure to the garden through autumn and winter.
  • Colchicums, or autumn crocuses, should be planted now for flowers this autumn.
