The short answer

Biggest risk
Chayote powdery mildew

Chayotes (Sechium edule) — perennial.

Unlike an annual crop, the work here is front-loaded into establishment: get the planting and the site right and the same plants crop for several seasons.

Core growing advice on this page is checked against named horticultural and university-extension sources — see References.

Stage BBCH Notes
Planting 0 Plant a whole mature fruit horizontally, sprouting end upward, about a third exposed above soil, or a stem cutting at least 20cm long, once frost risk has passed (Tropical Self Sufficiency).
Vigorous vine establishment 1 Extremely fast-growing trailing vine needs a sturdy trellis or fence and regular feeding as it climbs several metres; may need pruning to control spread.
Flowering and fruit set 6 Vine flowers and sets pale green, pear-shaped fruit; a long frost-free season is needed for fruit to develop fully.
Fruit and tuber development, harvest 8 Harvest young fruit at 10-15cm for tender skin, or leave to mature; the tuberous rootstock can be dug for use like a potato after a couple of seasons, and may resprout the following year in mild climates (zones 7a-11b).

When to pick: UF/IFAS: fruits develop "about 35 days after they are pollinated"; "Harvest chayote fruits young and the seed and rind will be soft and edible".

Storage

Best used fresh soon after harvest

Chayote powdery mildew

Podosphaera xanthii

Plant Disease/APS via PubMed: first US report of Podosphaera xanthii powdery mildew on mirliton (chayote), causing yellow irregular leaf spots progressing to necrosis.

Chayote anthracnose

Colletotrichum spp.

PMC/Brazil study: anthracnose caused by a complex of at least six Colletotrichum species (C. menezesiae, C. sicyi, C. karsti, C. chrysophilum, C. cucurbitacearum, C. plurivorum); explicitly NOT C. orbiculare.

Aphididae (various spp.)

Chayote is threatened by pests affecting squash and pumpkins generally, including aphids, cucumber beetles, squash bugs and melon flies.

Squash vine borer

Melittia cucurbitae

Squash vine borer affects chayote/mirliton along with other cucurbits; BT foliar sprays are the most effective management.

  8. Full sun. Heavy feeder, needs plenty of compost. Vigorous trailing perennial vine on a trellis, extremely fast growing (over 4 feet in two weeks from a new planting), needs pruning to control spread. Propagated by planting a whole mature fruit horizontally with a third exposed above soil level, or from stem cuttings at least 8 inches long. Harvest fruit immature at 4-6 inches long for tender skin, or leave to mature. The starchy tuberous root is used like a potato. Perennial vine, tropical/subtropical, requires a long frost-free growing season (120-180 days to harvest per wider horticultural literature); hardy in USDA zones 7a-11b where the rootstock can survive winter and resprout.

Science-based growing guides · Thresholds that hold in any climate

This guide states the conditions the plant itself responds to — soil temperature, frost tolerance, day length — rather than dates, because the same calendar month means opposite seasons in the northern and southern hemispheres. Anything genuinely restricted to one part of the world is named as such rather than presented as universal. Written and maintained by our editorial team against international horticultural research and extension sources.
