Here's the bit no seed packet tells you: on a lot of crops, picking is the growing. Leave the pods, leaves and fruits on the plant and it reads that as "job done" — time to make seed, not more food. Harvest steadily and you keep it in the mood to produce. It's the closest thing to a free lunch the veg patch offers.
It's July, everything's coming at once, so this is exactly the moment it matters. Grab a colander and let's go.
01Salad leaves: cut, never uproot
Loose-leaf lettuces, rocket, mizuna and the like are the classic cut-and-come-again crop. Shear off the outer leaves with scissors and leave the growing point in the centre intact — more leaves push up from the middle, ready again in a few weeks. The RHS reckons on six or seven pickings from a single plant that way. Pull the whole thing up and you get one meal. Same seed, wildly different value.
Pick young, too. Younger leaves are more tender and less bitter, and you stay ahead of the plant.
02Courgettes: small and often, or not at all
This is the one everyone learns the hard way. Pick courgettes at 10–12.5cm (4–5in) — small, tender, best flavour. Do it every couple of days. Regular picking while the fruits are small keeps the plant cropping for weeks.
Miss a few and they become marrows overnight, and here's the sting: a plant carrying a fat marrow slows right down on new fruit. One forgotten courgette genuinely costs you the next handful.
03Beans: every few days, no exceptions
Runner and French beans are ruthless about this. Pick runner beans young and stringless at around 20–25cm (8–10in), ideally every two to three days. Let pods mature and the plant stops flowering — no more beans, full stop.
French beans are the same story: pick at 15–20cm (6–8in), before you can see the beans bulging through the pod, and regular harvesting simply makes the plant produce more. Hunt carefully among the leaves — slim green pods hide brilliantly. What you leave on today is what stops tomorrow's crop.
04Peas: little and often, bottom-up
Pick peas regularly or the plants stop making flowers and pods — the same deal as beans. Pods fill lower down first, so start at the bottom and work up. Garden peas are ready when the pods are well filled; mangetout and sugarsnap go at about 7.5cm (3in), just as the peas inside start to swell. Eat them fast — sweetness fades from the moment you pick.
05Herbs: take from the top
Basil is the poster child for picking-as-pruning. Take the shoot tips, not the lower leaves — pinch out the top growing point just above a pair of leaves and the plant branches into two, then four, getting bushier and more productive each time. Strip the bottom leaves off a bare stem and you get a sad, leggy thing.
Snip any flower buds as soon as they appear, too — it keeps leaf quality up and delays the plant calling it a season. Most soft herbs respond to the same "pinch the tips" logic.
06Tomatoes: pick at full colour
Tomatoes don't crop harder for being picked, but timing still pays. Check plants every few days and pick each one, stalk attached, as soon as it's ripe and fully coloured. Clearing ripe fruit promptly keeps trusses tidy and lets the plant pour energy into the green ones still swelling behind them.
07Bolting: keep ahead of it
You'll hear that regular picking "stops" salad bolting. Be honest with yourself here — the real triggers are heat and dry soil, which is why watering well, mulching, and sowing in a bit of shade through high summer do the heavy lifting. But harvesting little and often genuinely helps: you're taking young leaves before they turn bitter, and cropping steadily rather than waiting for a big cut you'll never use in time.
08The honest bit about a glut
A courgette mountain isn't bad luck — it's a harvesting-frequency problem wearing a disguise. Almost every "too much at once" crop is really "not picked often enough." The fix isn't fewer plants; it's a two-minute walk round the patch every couple of days with something to put things in. Keep picking, and the plants keep giving. That's the whole trick.
