Southern England - detail & sources

Plant out a sprouted fruit or rooted cutting once all frost risk has passed and the growing season is warm enough to support 120-180 days of vigorous growth; a single window is applied uniformly across all four sub-regions since chayote needs a long frost-free season not achievable outdoors in most of the UK regardless of region, and is typically grown under cover.

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

A North American pest only -- native to the Americas and, per the Journal of Integrated Pest Management, not occurring outside the Western Hemisphere, so UK gardeners will not meet it. Where it occurs, larvae tunnel…

Plan your Chayotes planting

When to sow and plant Chayotes depends on your own frost dates. Check the UK vegetable planting calendar. To work out where it fits in your beds, sketch your plot in the free Garden Layout Planner.

Growing Chayote in another region

Sowing dates, frost timing and local advice differ by country. Use the guide for where you garden.

  1. Peer-reviewed

  2. Peer-reviewed. Explicitly found C. orbiculare NOT responsible for chayote anthracnose in this study, despite being the common cucurbit-anthracnose pathogen elsewhere -- used generic Colletotrichum spp. pathogen entity to avoid a wrong-species link.

  3. 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.

Frequently Asked Questions

When should I sow chayotes in the UK?

In Southern England, from early May. In Scotland, wait until early May. Treat these as a guide rather than a fixed date — the governing rule is to sow only once frost risk has passed and temperatures are reliably warm enough.

When do I sow chayotes?

Sow early May to early June.

What soil pH do chayotes need?

A pH of about 5.5–7. That span reflects genuine variation between the authorities we cite rather than a single agreed figure — the References section lists each source's exact range.

What problems affect chayotes?

Our data links 2 diseases and 2 pests to this crop. See the sections above for each one and how to manage it.

Plan next season before the problems start

Most of the advice on this page comes down to timing and spacing — sowing at the right moment, rotating beds, and giving plants enough airflow. The UK Garden Planner lays your plot out month by month so those decisions are already made before the season starts.

How this guide is put together

The growing data on this page — sowing windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against RHS and Met Office guidance. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
