Chayote is picked immature, like a courgette rather than like a squash. The right fruit is three to six inches (8 to 15 cm) long, firm, pale to mid green, with skin thin enough that a thumbnail dents it and leaves a wet mark. At that stage the flesh is crisp, mildly sweet, and the single seed inside is soft enough to eat.
Leave it another two weeks and the skin toughens into something you have to peel properly, the flesh goes fibrous around a hardening seed, and any spines on a prickly type harden into genuine splinters. The fruit is still usable but it is no longer good. Fruit reaches picking size roughly three to four weeks after the flower sets, and once the vine starts you should be checking every two or three days.
Look from underneath. On an overhead frame the fruit hangs clear of the leaves and a walk beneath the canopy with a torch will show you far more than looking down from above.
Fruit hidden inside a dense canopy is how a glut turns into a pile of woody rejects. Thin the canopy in late summer specifically so you can see what is hanging.
Cutting rather than pulling
Chayote holds on hard. Twisting or pulling tears the stem, damages the shoot it was attached to and can rip a whole side branch off a heavy vine. Use pruners or a knife and cut the stalk about half an inch (1 cm) above the fruit. That short stub is also the part that shows you how fresh a stored fruit is: it shrivels and browns first.
- Wear gloves before you start The sap around the cut stem and, more importantly, in the skin when you peel it, dries into a tight film on your hands. Many people find their fingers go sticky, then tight, then rough and flaky for a day or two. Thin nitrile gloves prevent it entirely.
- Cut with a short stalk attached Half an inch (1 cm) of stalk left on the fruit seals the wound and roughly doubles how long it keeps. A fruit torn off at the shoulder starts breaking down at the scar within days.
- Handle the skin as if it bruises, because it does Young chayote marks easily and a bruise turns into a brown sunken patch in storage. Lay fruit in a shallow crate in one or two layers rather than filling a bucket to the brim.
- Do not wash before storing Brush off soil dry and store unwashed. Wet skin in a cold fridge drawer is the fastest route to soft rot. Wash immediately before cooking instead.
- Peel under running water or in a bowl If you would rather not wear gloves, peel the fruit submerged or under a running tap. The sap disperses in water instead of drying on your skin. Peeling is optional on very young fruit; the skin is edible when a thumbnail still dents it.
Storing a genuinely enormous crop
One established chayote crown is not a modest producer. In a good autumn a single mature plant commonly yields fifty to a hundred fruit, and vigorous plants on a large frame go well past that. It arrives over a few weeks, all at once, and it will overwhelm you if you have no plan. The good news is that chayote stores better than almost any other summer vegetable.
The fruit is chilling sensitive at the extremes: it keeps best cool but not cold, and long spells below 45F (7C) cause pitting and hasten breakdown. A cool room, a garage or a cellar often beats a fridge for a big harvest.
| Storage method | Conditions | How long it keeps | Notes |
|---|---|---|---|
| Cool room or cellar | 50F to 55F (10C to 13C), dry, in a single layer | Four to eight weeks | Best option for a large harvest; check weekly and remove any softening fruit |
| Refrigerator drawer | Around 45F (7C), unwashed, loose in paper | Three to four weeks | Do not seal in plastic; condensation causes rot at the stem scar |
| Kitchen counter | Room temperature | One to two weeks | Fruit will begin sprouting, which is useful only if you want planting stock |
| Frozen | Peeled, diced, blanched two minutes, then frozen | Six to eight months | Texture softens; suits soups and stews rather than salads |
| Pickled | Sliced raw into a hot vinegar brine | Months, refrigerated after opening | Keeps the crunch better than freezing does |
Leave a few, and remember the roots
Set aside two or three of the best late fruit and do not eat them. Left whole in a cool dark place they will sprout on their own, and those are your plants for next season. A fruit you grew yourself and never refrigerated hard is far more reliable planting stock than anything bought.
The young shoot tips are also edible, picked in the top six inches (15 cm) while they snap cleanly, and they are worth taking through the summer when there is no fruit yet. Where the crown survives more than one winter the swollen storage roots become edible too, dug at the end of the season like a starchy tuber, though digging them ends that crown.
What to record at harvest
Note the date you cut the first fruit and the date of your last, along with a rough count or weight of what came off the plant. Add the date of the first frost that stopped it. Over two seasons this tells you exactly how much of your crop the season length is costing you.
Also record which fruit you kept back for planting and where you put them, because by the time they sprout you will have forgotten. A label with the parent plant's position on it closes the loop from one year to the next.
