Here’s what to sow and grow in the vegetable garden this August:

In the greenhouse / indoors

  • Sow winter lettuce such as 'Arctic King' or 'Winter Gem' in modules to plant out later this month.
  • Sow parsley, coriander and chervil in seed trays now for growing under glass throughout the winter.
  • If you have a greenhouse you can still sow dwarf beans such as 'Delinel' for an autumn crop.

Direct sow outdoors

Plant outdoors

  • Plant out summer/autumn cauliflower ‘All The Year Round’ early in the month for an autumn harvest.
  • Finish planting out winter cabbage ‘Winter Jewel’ early in the month, allowing about 45cm between plants as they get quite big!
  • Finish planting out kale plants for winter and spring cropping.

Fruit to sow and grow

Try growing these fruits this month:

  • Plant newly pot grown strawberry plants (or your own runners as soon as they have rooted) in an area where you haven’t grown strawberries for three years or more to avoid disease. Planting now will allow them to establish well before winter.
