tips for harvesting common allotment vegetables

Best Vegetable Harvesting Tips, Fresh and Perfect Gardening

Harvesting can be a neglected allotment skill, and the tips were designed to help make sure I reminded me to take care when picking crops.

When Should You Harvest Your Vegetables?

Harvesting produces when at its peak is also dependent on the type of vegetable. For example, French beans need to be picked young and tender, whilst tomatoes are best left to ripen on the plant as long as possible. Here are some tips I’ve picked up for harvesting individual crops.

Harvesting Tips and Based on Vegetables

Watch the Vegetables’ Size 


For me, the perfect beetroot is the size of a tennis ball. Beets will sit in the ground and wait patiently to be picked, but don’t let them get too big or they will become woody.

Brussel Sprouts

Although sprouts remain perfectly palatable when full size, it’s the little ones that are the real treats. Start harvesting from the bottom, and pull off the dead, yellowy leaves as you go.


I like to pick cucumbers when they are about half the length of the ones you find in the shops. These will be delicious but also allow other cues on the plant to grow.


Watch out for the very top of the carrot poking through the soil. I harvest when they’re 3-4mm above the surface. Don’t leave them too late as they’ll split.

Pay Attention to the Stem 

Cavolo Nero & Kale

Pick the leaves just above where the stem meets the plant when they are a deep green colour. About 10cm – 13cm is perfect for a kale leaf, whilst cavolo nero can be a bit longer.

Harvest regularly to allow for new shoots to come through, but try to vary the plants you pick from so they all get ample time to recover.

Chard & Perpetual Spinach

Chard is a very robust plant and responds well to regular harvesting. Again, cut the leaves off where the stem meets the main plant. 15cm is a nice size for a chard leaf.

Harvest These Vegetables by Their Color


When the potato leaves turn yellow, the crop will stop growing. The potatoes will sit in the ground without complaint until the soil becomes soggy. Get them out before then so they don’t rot.


Don’t be tempted to pick a pale tomato – you’re missing out! Try and leave the fruit on the plant until fully reddened. This way, you’ll guarantee your tomato will be as tasty and juicy as possible.


Look out for the husks turning brown. Then pull back the husks and make a small incision into the kernel. If the corn is ripe, the juice will squirt out. If the juice is thickish, the corn is ripe.

Check These Vegetables Regularly


Check courgette plants every day – turn your back for a minute and you’ll end up with marrows! Courgettes are ready when about 15cm long, although the cigar sized ones are very tasty indeed…

French Beans

It is a fine line between a tender and a tough French bean. Try to harvest before the seeds in the pods become distinct, as this is when the bean will be at its sweetest. Visit the plant as regularly as possible to keep on top of the heavy cropping, and picking will encourage other beans to form.

Runner Beans

Like French beans, try to pick the pods young, before the seeds are visible. About 8 inches is a good size. Much bigger and they’ll start to become stringy.


Keep an eye on your radishes, as they will soon go woody. They grow fast, so sowing little and often is the key with these peppery salad veg.

Unique Qualities to Observe Before Harvesting


I’ve found Leeks to be a winter harvester’s dream. They’re in no rush and will stay happily in the ground until you’re ready. So if it’s raining and miserable, you can pick them another day.

Onion and Garlic

Red and white onions and garlic are ready to pull when the stalks die off and bend over.


You can tell if the pea is definitely ready to harvest if you shake the pod and hear the peas rattling inside.

Purple Sprouting Broccoli

Pick flower shoots, or mini florets just before the flower buds open.

  1. Thanks CJ. I enjoyed putting it together. ad forgotten that lots of veg aren’t just ones you grab off the plant.

    Sweetcorn is my favourite, its almost like a science experiment!

  2. Excellent advice Jono – all I seem to do at the moment is walk round with a bucket in my hand choosing the best of the crops to harvest – as you say it is a fine line and you have to be vigilant – I love this time of year when all the plans I made in spring finaly come to fruition.
