How to preserve your harvests

Don’t waste your home-grown produce if there's too much for you to eat all at once – many fruit and vegetable crops can be stored, frozen or dried for enjoying later.

It’s really satisfying to see your shed, cupboards and freezer stocked up with home-grown produce, and it will also save you money, helping to feed the family through until next season.

When storing, it’s important to pick all fruit and vegetables in their prime and discard any that are damaged. Chill perishable crops, such as berries and stone fruits, if you can’t process them straight away. Don’t wash newly harvested veg until just before preserving, as this can encourage the growth of bacteria.



Several types of roots and fruits can be stored in a cool, well-ventilated spot, such as a shed or garage, until required. Root crops lose moisture and shrivel if kept in a dry place.

Suitable for: root crops, onions and top fruit. Use within six months.
  • Lift root crops, such as carrots, remove the leaves and shake off any loose soil. Store them in layers of damp sand in a dark shed. 
  • Sun-dry potatoes to harden the skins, then store them in hessian sacks in a dark place. Regularly check for signs of rot. 
  • Dry onions in the sun, then cure them in a porch or spare room until the skins are papery. Plait them together in strings. 
  • Wrap unbruised apples in newspaper and store them in boxes in the shed.


Low temperatures inhibit the growth of bacteria that spoil food. Blanching before freezing also kills bacteria and maintains the vitamin content of the crop.

Suitable for: root crops, onions, top fruit, soft fruit, veg fruits, tomatoes, pods and cobs, brassicas. Use within six months.

  • Open-freeze currants on their stems and berries on trays before bagging.
  • Blanch veg in boiling water straight after picking. Cool them quickly, then dry them and pack them in bags. Beans, sprouts and broccoli are successful.
  • Slice apples and plums, toss with lemon and sugar, then freeze.
  • Juice apples, pears and plums and freeze in small quantities.


Bacteria need water, so drying out food prevents them from multiplying.

Suitable for: onions, top fruit, veg fruits, tomatoes, pods and cobs. Use within six months.

  • Core apples, then slice into rings and soak in salt water. String the rings on washing lines indoor, well spaced apart, for three to five days. Use this technique for chillies and mushrooms too, but drying times will vary.
  • Cut tomatoes in half, then cover with salt and dry them on baking parchment in the oven. Store in jars of olive oil.
  • Slice onions, dip in boiling water for 30 seconds, then dry on baking trays.
  • You can buy a dehydrator for around £50, or use an oven on a low heat.
