An excellent way for home gardens with restricted space to expand what they are able to grow and yield a bigger harvest is to implement vertical gardening into their system. Vertical gardening is merely moving the direction of the growth of your plants from the ground to the air. The easiest ways to do this is to attach garden trellis netting to the rear of your growing boxes or indeterminate vegetables.
Lots of vegetable varieties can naturally grow vertically, even a few that you will not expect. Traditional plants from your local hardware store or nursery will be the bush varieties, intended to bush out or grow over the ground. If you look closely however, you will find that there are also vine varieties of the same plant. The label on the vegetables will likely say something regarding either indeterminate or vine type transplants.
