How to grow chayote

Sechium edule · Cucurbitaceae · Vegetable

Chayote is a warm-season vegetable in the Cucurbitaceae family, usually started indoors and set out as transplants. It wants full sun (six or more hours of direct light) and consistent moisture — it resents drying out. From sowing to first pick is about 120–150 days. It is killed by frost, so nothing goes outside until the danger has passed and the soil has warmed.

Grower’s note: Grown by half-burying a whole sprouted chayote fruit at an angle. One vine can run 30 feet or more and yield dozens of mild, crisp squash-like fruit in fall. A short-lived perennial where it never frosts; elsewhere it needs the longest possible frost-free season.

Sowing

Sow about 3″ deep, into soil between 65–90°F — germination is quickest near 80°F. It is slow and often erratic to germinate (14–28 days). For an early crop, start seed indoors about 5 weeks before your last spring frost and grow it under bright light.

Spacing & layout

Give each plant about 120″ along the row with roughly 120″ between rows. On a square-foot grid that is one plant per 4 square feet. Allow at least 24″ of loose, workable soil for the roots. It needs more root room than most containers give and does best in the ground.

Fitting it to your season

Chayote needs roughly 120–150 frost-free days to crop. Where the season is shorter than that, start it indoors and choose the earliest-maturing varieties, or grow it in a container you can move under cover on cold nights. In long, hot-summer regions it can often be planted twice — once in spring and again in mid-to-late summer for a fall harvest.
