Home gardens have been popular for years. It is the pleasure of growing your own food, at least in part, that makes the practice popular. In addition, it allows one to know what was placed on the plant, if anything, to fertilize and to repel insects.
One consequence of climate change is conditions are not static. In fact, conditions in one place might vary greatly over a year. As temperatures rise it would, at first thought, seem to expand the growing season. But it can get too hot for vegetables. In this area eggplants can form brown spots in the extreme heat of summer. And, as the temperature rises tomatoes and beans fail to set. These are not unique, but they are given as examples of what happens as summer gets too hot for plants to produce.
Another problem is stronger storms, with hail occurring more frequently.
