Making the Most of Your Allotment Glut
As we begin to move into the main growing season, many allotment holders are already looking ahead with anticipation to the months of harvesting. After weeks and months of sowing, planting, and tending, it is one of the most rewarding times of the year.

However, with abundance often comes excess. Courgettes suddenly arrive in numbers, beans appear almost overnight, and fruit bushes can quickly overwhelm even the most organised grower. Food preservation is therefore an essential part of allotmenteering—helping reduce waste, extend the harvest, and enjoy homegrown produce throughout the year.
Below is a guide to key preservation methods, along with simple ideas and practical guidance for using allotment produce.
🍓 Jams, jellies and chutneys
One of the most traditional and widely used methods of preservation, using sugar and fruit acids to store produce safely for months. The best part of having an allotment is that you can use whatever you have and mix and match.Best crops:
strawberries, raspberries, blackcurrants, plums, apples, rhubarb
Garden Jam (Allotment Classic)
Ingredients:- 500g strawberries
- 250g raspberries
- 250g rhubarb
- 900g granulated sugar
- Juice of 1 lemon
- Place fruit and lemon juice into a large preserving pan.
- Heat gently until the fruit softens and releases juice.
- Add sugar and stir until fully dissolved.
- Bring to a rolling boil for 8–10 minutes.
- Test for setting point, then pot into sterilised jars and seal.

🧊 Freezing
Freezing is one of the simplest ways to preserve crops at peak freshness with minimal preparation.
Best crops:
peas, beans, courgettes, berries, sweetcorn, herbs
Frozen herb cubes
- Chop mixed herbs (parsley, thyme, chives)
- Add a little water or stock
- Freeze in ice cube trays

🍅 Bottling (how to preserve tomatoes and soft fruit)
Bottling is one of the most effective ways to store allotment produce long-term without relying on freezer space.How to bottle allotment produce safely
Best crops:
tomatoes, plums, pears, apples, berries, stewed fruits, sauces
Basic equipment:
- Kilner jars or screw-top preserving jars
- Large pan or water bath
- Funnel and ladle
- Clean tea towels
- Prepare the produce – wash, chop, or lightly cook fruit/vegetables depending on the recipe.
- Sterilise jars – wash thoroughly and place in a warm oven (around 120°C) for 10–15 minutes or fill with boiling water.
- Pack the jars – fill with hot produce, leaving a small headspace at the top.
- Add liquid – syrup, juice, or tomato liquid depending on what you are preserving.
- Seal immediately – tighten lids while contents are still hot.
- Heat process (if required)– place jars in a water bath for 20–40 minutes depending on contents.
- Cool and check seals – lids should be concave and fully sealed before storage.

🍲 Sauces, purées and soups
Turning gluts into ready-made meals is one of the most practical preservation methods.Best crops:
courgettes, tomatoes, beans, mixed vegetables
Unusual idea: Courgette, lemon & herb sauce
Blend cooked courgettes with garlic, lemon zest, and herbs for a light pasta sauce that freezes well.
🌬️Drying and dehydrating
Drying concentrates flavour and extends storage life significantly.Best crops:
herbs, chillies, apples, tomatoes
Something to try: Allotment herb salt
Blend dried rosemary, thyme, parsley, and sea salt for a versatile seasoning.

- Blend beetroot, berries, sugar, lemon juice, and water until smooth.
- Pass through a sieve for a smoother texture.
- Chill thoroughly.
- Freeze, stirring every 30–60 minutes until set, or churn in an ice cream maker.
- The result is an earthy, vibrant sorbet with a deep colour and refreshing flavour.
🥬 Fermentation and pickling

🧺 Storing crops for winter
Not all produce needs to be frozen or turned into preserves, with many traditional allotment crops storing exceptionally well when kept in the right conditions. Potatoes, onions, garlic, apples, squashes, and root vegetables can often last for several months in cool, dark, dry, and frost-free spaces. Potatoes store best in hessian sacks or paper bags, onions and garlic should be properly dried before hanging or placing into nets, while apples are best stored carefully in trays or wrapped individually to prevent spoilage spreading. Traditional storage methods remain one of the simplest and most effective ways to enjoy homegrown produce throughout autumn and winter.

Final thoughts
Preserving the harvest is an essential part of allotmenteering. It reduces waste, extends the growing season, and allows growers to enjoy the results of their work long after the beds have been cleared.
From traditional jam making and bottling to freezing, drying, fermentation, and even sorbets, there are countless ways to make the most of every crop.
As the growing season begins, it is worth planning not only what to grow—but how to preserve and enjoy it throughout the year.
