When to Harvest Apples (and How to Store Them)

Pick an apple too early and it's starchy, sour and prone to shrivelling in storage; leave it too long and it goes mealy on the tree or ends up as wasp food in the grass. The window for any one variety is only a couple of weeks wide — but the tree gives you clear signals when you know what to look for. Here's how to read them, and how to store a glut so you're still eating your own apples months from now.

First, know your variety's season

Apples divide roughly into three harvest groups, and the group matters more than any date on a calendar — a Discovery and a Granny Smith may hang on the same fence line yet ripen ten weeks apart.

Tip: First-time grower with an unknown tree? Watch for the first sound, undamaged fruit dropping on their own — that, plus the tests below, brackets the harvest window for whatever variety you've inherited.

The five signs an apple is ripe

• The lift-and-twist test — the most reliable. Cup the apple, lift it level and give a slight twist: a ripe fruit separates from the spur easily, stalk intact. If you have to yank, it isn't ready.
• Brown seeds. Cut a sample apple open: ripe seeds are dark brown, unripe ones pale or white. (A sacrificed apple per tree per week is a fair price for good timing.)
• Ground colour shift. Ignore the red blush, which develops long before ripeness. Look at the background skin — typically it loses its grassy green and turns yellowish as the fruit matures.
• Flesh and flavour. Ripe flesh is cream-coloured rather than greenish-white, and the starch has converted to sugar — an unripe apple tastes of nothing much and squeaks against your teeth.
• Ripe fruit starting to drop. A few sound windfalls (not just pest-damaged June drops) mean the tree itself has decided.

How to pick without bruising

An apple bruises more easily than it looks. Pick with the palm rather than the fingertips, lay — don't drop — fruit into the basket, and never tug so hard you pull the spur off with the stalk, since spurs are next year's fruit buds. Keep the stalk on the apple: a torn stalk cavity is an open door for rot in storage. Work through the tree in two or three passes a week or so apart, since sun-facing fruit ripens first.

Storing apples so they last

Storage is where a good harvest is won or lost, and the rules are strict but simple.

• Store only perfect fruit. Anything bruised, split, holed or lacking its stalk goes for immediate eating, cooking or juicing — one rotting apple genuinely does spoil the barrel.
• Cold, but not freezing: 0–4°C is ideal. An unheated cellar, garage or shed works; so does the bottom of a fridge for modest quantities.
• Keep humidity high so fruit doesn't shrivel — apples like it damp and cold. Perforated plastic bags in the fridge, or trays in a naturally humid cellar, both work.
• Lay fruit in a single layer, not touching, in shallow trays or boxes; wrapping individual apples in paper is old-fashioned but effective at stopping rot spreading.
• Check weekly and pull anything softening or spotting before it infects its neighbours.

Warning: Apples give off ethylene, a ripening gas. Store them away from your other produce — ethylene makes potatoes sprout, carrots turn bitter and green vegetables age fast. For the same reason, a bag of apples in the fruit bowl accelerates every banana next to it.

Early apples: a different rhythm

If you grow an early variety, forget everything above about storage. Earlies go from perfect to woolly within days — sometimes on the tree itself — so pick them slightly under-ripe if anything, keep them in the fridge, and eat them inside a fortnight. Their job is the taste of late summer, not the winter store.

What about apples that won't ripen?

A tree loaded with small, hard, stubbornly green fruit in mid-autumn is usually carrying too heavy a crop, is short of sun, or is simply a very late variety. Late keepers often taste unimpressive straight off the tree — many, like Braeburn and Granny Smith, genuinely improve after a month or two in cold storage as starches finish converting to sugar. Not sure which problem you have — or which apple you've got? Snap the fruit and leaves with the PlantMe app and it will identify the tree and flag pest and disease issues from its 35,000+ plant database.
