If you're reasonably new to vegetable gardening, it's easy to lose focus at this time of year. The tomatoes are spilling out all over the section, the lettuces would feed the whole town and the courgettes are bigger than the house.
But you do need to be thinking about what you're
going to eat when the summer flush is over and you can't look another lettuce in the face.
It's likely you'll need more space, so either free up existing space by harvesting, or create a new garden area, accepting that it may be the first of several. Turn over the soil, dig in some compost, and get planting again. Sow onions, beetroot and carrots for autumn and winter eating, as well as winter crops of cabbage, cauliflower and broccoli.
Bear in mind that vegetables you thought you didn't like much (cabbage, perhaps, and radishes) taste completely different when you've grown them yourself.
And also remember than the pleasure of producing your own food is matched by the pleasure (and pride) in having a surplus to give away.
