  • • For flowers that bridge the gap between spring and summer try growing Forget-me-nots, Foxgloves, Sweet William and Wallflowers in seed trays now for flowering next year.
  • • Sow winter-flowering pansies in seed trays now, so that they will be ready for your winter containers.
  • • Sow perennial Scabiosa now in pots or trays for years of attractive flowers which are loved by bees and butterflies.

  • • Scatter Nigella seeds in your borders now for some striking blue late-summer flowers.
  • • Grow the tallest Sunflower from direct sowings  - great fun for the kids!

  • • Sow courgette and squash seeds in pots or directly outside now.
  • • Think ahead to winter cropping and start kale seeds in a nursery bed now.
  • • For something more unusual try sowing kohl rabi where it is to grow - it will be ready in as little as 8 weeks after sowing.
  • • Try direct sowing nutritious Pak Choi every 3 weeks for a continuous crop.

  • • Direct sow spinach seeds in soil enriched with plenty of organic matter. Try growing Spinach 'Perpetual' if you have very dry soil.
  • • Sow spring onion seeds in drills outdoors for a quick crop to add to salads and stir fries.
