Grow Your Own
The Chayote likes a warm climate and is a very aggressive vine. It is perfect in a sunny spot where it can climb on a fence or trellis. The fruits are heavy and need some support.

To start a plant, purchase a chayote from the store and try to find one with a "bud" on the end. You can just sit the chayote in a warm window (not direct hot sun) and it will begin to wrinkle and eventually produce a bud. The chayote can then be placed in some sandy soil (partially covered). Once the plant shows vigorous growth it can be transplanted outside. Water as you would any squash.
