That's a pickle
If you don't know how to dry or bottle produce that you can't eat, consult somebody's aunt or grandmother. If you have excess, pickle or bottle something once a week.
Store with relish
Slow-roasted tomatoes will keep well packed in oil, while courgettes and beans are easy to freeze. Check out old family recipe books for chutney and relish recipes.
In a bind
Grab ties and stakes and tie up anything that's in a state of collapse, from tomatoes to beans to grapevines.
When powdery mildew appears on your courgettes and other plants, give them a spray with a mix of 5g bicarbonate of soda in 600mls of water.
