How to Grow Chayote
Sechium edule
Chayote is a vigorous tropical climbing vine grown for its pear-shaped fruits. Unlike most vegetables, the whole fruit is planted — place it half-buried on its side in warm compost indoors before the last frost. It needs a strong trellis and plenty of space as it will quickly cover several square metres. Once established, it is a heavy feeder and drinker. Harvest fruits young and regularly to keep the vine producing. Shoots and young leaves are also edible and can be cooked like spinach.
When to Start
Start seeds indoors 3 weeks before your last frost date. Transplant outdoors once night temperatures stay above 12°C and soil has warmed to at least 15°C.

Care Essentials
- Feed monthly with a balanced fertilizer during the growing season once the vine is established.
- The whole fruit is planted — not seeds. Place the entire fruit on its side, half-buried, in a warm spot indoors before the last frost. The entire plant is edible — fruit, shoots, leaves, and tuberous roots.
