Ready to pick? The lift-and-twist test will tell you
Pick too early and the apple stays sour; pick too late and it turns mealy and won't keep in storage. One simple move at the tree tells you when the moment is right.
September is the month when I walk around the same tree several times with a basket under my arm. Apples don’t all ripen on the same day — not even on a single tree. Strip everything at once and you’re bound to get some underripe and some past their best. Three simple checks will get you much closer to the right moment.
Ready to pick is not the same as ready to eat
This is where most of the confusion starts. Ready to pick means the fruit has finished growing and can come off the tree without damage. Ready to eat means it tastes its best right now.
With early varieties the two nearly coincide — you eat those within days of harvest or not at all, because they simply don’t store. Classic keeping varieties, on the other hand, often taste hard and sour straight off the tree and need weeks or months in a cool cellar while their starch converts to sugar. An apple that disappoints you in mid-September can be exactly right by November.
The lift-and-twist test is the most reliable check
Cup the apple loosely in your palm, lift it slightly and twist it about 90 degrees to the side. If the stalk separates cleanly from the branch, the fruit is ready to pick. If you have to pull or tear, leave it hanging and try again in a week.
The reason is simple: as the fruit ripens, the tree forms an abscission layer — a zone of separating tissue between stalk and fruiting spur. That layer is the real indicator of ripeness, and it doesn’t lie, whereas colour and size easily can.
What the seeds and the ground colour add
Cut one fruit across and look at the seeds. If they are dark brown rather than pale beige, ripening is well advanced. This test is less dependable on very early varieties, but it is a solid second opinion on keeping varieties.
Also watch the ground colour — the shade underneath the red blush. As the fruit ripens it shifts from grass green through pale green to yellowish. The red cheek on its own tells you little; that comes from sunlight, not from ripeness.
A few windfalls are a hint, but no proof. Dropped fruit with a small bore hole near the calyx usually means codling moth, and it fell early. Collect those straight away: the larvae leave the fallen fruit before long, overwinter in bark crevices or in the soil, and emerge as the next generation come spring.
Picking properly: the fruiting spur stays on the tree
The stalk belongs to the apple, the fruiting spur belongs to the tree. That is exactly where next year’s flower buds sit — tear one off and you lose the crop from that spot next season.
Pick on a dry day if you can, and not while morning dew is still sitting on the fruit. Moisture on the skin is an open invitation to storage rot. And place the apples into the basket rather than dropping them in: every bruise you cannot see today will be a brown patch in four weeks.
Storing them: cool, humid, dark and strictly sorted
Only flawless fruit goes into storage. Anything with a bruise, a scab spot or a worm hole goes onto the kitchen table to be eaten or processed first — a single rotting apple will take a whole crate with it.
Aim for roughly 2 to 6 degrees Celsius, high humidity and darkness. An unheated cellar, a frost-free garage or a cool, frost-safe storeroom all work well. An attic is rarely a good choice — the temperature swings too much up there. Lay the apples out in a single layer or in shallow crates so they are not pressing on each other.
Two things matter. Apples release ethylene, a ripening gas, so vegetables stored alongside them age faster: cabbage yellows, root vegetables wilt sooner. Keep potatoes separate in any case, because apples take on their earthy smell and end up tasting musty. And check through the crates every week or two — anything starting to rot comes out immediately.
Write down this year what you will want to know next year
A tree’s harvest window shifts from one year to the next — usually by a few days, in extreme years by one or two weeks. So if you note down when each tree was ready, how much it carried and how long the fruit lasted in the cellar, next September you will not be purely guessing; you will be working from experience.
That is exactly what the garden journal in Rootivo is for: date, quantity, a short note, done. After two or three years you can see your trees in numbers — and you will know which variety really keeps in your conditions and which one is better processed straight away.
