July and August see the last harvests of many spring-planted vegetables so it's a good idea to sow and plant more veg to fill the gaps these harvest create. It's best to sow the new veg in modular trays and then plant out once it's big enough. However carrots work best when sown direct. You can make the most of space by sowing it between existing veg plants so that it can get started while the previous crop is finishing. You can also plant new veg between existing veg in the same way.

In July, sow kohlrabi, lettuce, leaf beet, chard, endive, chicory, Florence fennel, carrots, spring onions chervil and coriander.
Finish sowing beetroot and savoy cabbage in the first week of July.

After mid-July, sow land cress, Chinese cabbage and spinach.

From the end of July to mid-August, sow mustards, pak choi and salad rocket.

In mid-August, for planting outdoors to grow under a cloche, any salads and leaves for stir-fries.

In late August (to overwinter small plants), spinach, spring onions, Japanese onion, spring cabbage and lettuce.
