Mulching

If you can get it around crops, pretty much anything can be mulched. I normally start with toms, sweet peppers, egplants, cukes, then onions/leeks and see if there's anything left for other crops. I noticed a group of gardeners who hilled up carrots and beetroot against pests and to retain moisture. Compost would do the same.

If t at all possible, mulch after a rainfall so there's moisture to retain. If none for the future, just mulch anyway.
