Growing Chayote in the South: The Prolific Vine You Can Eat Root to Tip

Chayote Is One of the Most Productive Vines in the Southern Garden

Chayote squash is one of those vegetables that most Southern gardeners have never grown but would plant every year if they tried it once. This vigorous tropical vine native to Mexico and Central America produces an enormous crop of mild flavored green fruits that taste something like a cross between cucumber and zucchini but with a denser texture. The vine also produces edible young shoots, edible leaves, and edible tubers at the root. Almost every part of the plant is useful, which makes it one of the most productive food plants per square foot in the Southern garden.

Why the South Is Perfect for Chayote

Chayote loves heat, humidity, and a long growing season. It is a tropical and subtropical plant that performs best in zones 8b through 11 where the warm season is long enough for the vine to establish, climb, and produce heavily. In zones 10 and 11 chayote is essentially a perennial that lives for many years. The massive tuberous root system that develops over several seasons produces a huge flush of new growth each spring and the vine becomes more productive with each passing year.

In zones 8b through 9b chayote is grown as a warm season annual. The vine needs at least five to six months of frost free weather to establish and fruit, which is tight in zone 8b but achievable with early spring planting.

Planting Chayote

Chayote is planted from the whole fruit, not from seeds or seedlings. You plant an entire chayote with its seed still inside. The sprouted fruit, which you can find at Latin grocery stores and increasingly at regular supermarkets, is simply placed sprouted end slightly downward in a mounded hill of rich, well amended soil with the stem end exposed. The sprouted vine emerges from the seed end and the whole plant grows from there.

Plant after all frost risk is past and soil is warm. In zones 10 and 11 plant from February through April. In zone 9 plant in April. In zone 8b plant in May for best results. The vine grows fast in warm conditions and will need a very sturdy trellis, fence, or tree to climb. Left to sprawl it still produces but trained on a structure it is much easier to harvest and the air circulation reduces disease.

Growing Requirements

Chayote is a heavy feeder and a heavy drinker. Unlike drought tolerant Southern crops, it wants consistent moisture and rich soil to produce maximally. Amend planting hills with generous compost. Feed monthly with a balanced fertilizer. Water consistently through dry periods. Mulch heavily to retain moisture and keep the root zone cool.

The vine grows vigorously, easily reaching thirty feet in a single season in zones 10 and 11. Provide adequate support from the beginning. It produces tendrils like a grape vine that grab and hold anything they touch.

Harvesting Chayote

Harvest the fruits when they are the size of a large pear and still firm. Smaller fruits tend to have better texture. Overripe chayote becomes pithy. A single established chayote vine in zone 10 or 11 can produce one hundred or more fruits in a season. This is genuinely an overwhelming amount for most households, so plan for preserving and sharing.

The young shoot tips and leaves of the vine are excellent cooked as greens. Saute with garlic and olive oil like you would any tender greens. The shoots are particularly good in stir fries. In zones 10 and 11 where the vine is perennial, digging the large tubers after several years and cooking them like potato is a bonus harvest from the same plant.

Using Chayote in the Kitchen

Chayote is mild and versatile. It works raw in salads, pickled, sauteed, stuffed and baked, in soups, or in stir fries. The mild flavor absorbs seasonings well and the texture holds up to cooking better than summer squash. It is popular in Caribbean, Latin American, and Asian cooking and once you have fresh chayote from your own vine you will find uses for it constantly.

Adding Chayote to Your Southern Food Garden

Chayote slots beautifully into the vertical layer of a food forest or along a back fence line where its enormous vine coverage provides both shade and food production.
