Stakes

Some plants need stakes, and it is pointless growing them if you do not stake them up. If you stake tomatoes properly for example, you can get your plants to grow a few meters high, and also this keeps the fruit off the ground where all the hungry bugs are.

That's about it. You just have to weed and water then until it is time to pick your crop. If you stagger your crop, you will always have something on the go, and you can have fresh veges every night.
