Why Summer Is the Most Important Preserving Season
For home canners, summer is not a time to relax — it's the busiest and most rewarding season of the year. From late June through August, fruits and vegetables arrive in rapid succession, each at their flavour peak for just a few weeks. Timing your preserving correctly means you'll fill your pantry with ingredients that are naturally at their sweetest, most aromatic, and most nutritious. Miss the window, and you'll be paying premium prices for inferior produce in winter.
June: Strawberries, Cherries & Early Herbs
June marks the official start of fruit season in most temperate climates. Here's what to focus on:
- Strawberries — Peak jam season. Choose firm, deeply coloured berries. Avoid overripe fruit for preserves. Make jam, strawberry compote, and strawberry syrup.
- Sweet cherries — Begin arriving mid-June. Perfect for compotes, cherry jam, and cherry syrup. Pick and process quickly — cherries deteriorate fast after harvest.
- Sour/morello cherries — Often arrive late June. Exceptional for jam and compote due to their natural acidity and intense flavour.
- Fresh herbs (dill, basil, tarragon) — Dry or freeze for use in pickling later in the season. Dill flower heads are especially valuable for cucumber pickles.
July: The Peak of Summer Abundance
July is arguably the single most productive month for the home preserver. You'll be working almost every weekend if you want to catch everything at its best.
- Raspberries — Short season, incredibly fragrant. Make raspberry jam, raspberry and redcurrant jelly, or freeze whole for winter compotes.
- Redcurrants & blackcurrants — Both are naturally high in pectin, making them excellent jam partners. Blackcurrant jam is particularly rich in vitamin C.
- Cucumbers — Begin arriving in bulk. Start your first batches of fermented pickles and vinegar cucumbers.
- Apricots — Intense flavour in a short window. Apricot jam is a classic; apricot compote is underrated.
- Courgettes/zucchini — Pickle in vinegar brine with dill and garlic for a crispy, surprisingly delicious preserve.
August: Stone Fruits, Tomatoes & the Big Pickle Push
August brings the richest, heaviest harvest of the year — and the most intensive preserving work.
- Plums — Hungarian/Italian prune plums are ideal for thick, spreadable plum jam. Early August plums work beautifully in compote.
- Peaches and nectarines — Preserve in light syrup as whole halves for an elegant winter dessert. Also excellent in jam.
- Tomatoes — Make tomato purée, crushed tomatoes, or lecho (pepper and tomato stew in a jar). August tomatoes are at their absolute sweetest.
- Sweet and hot peppers — Marinate in vinegar brine or add to mixed vegetable pickles.
- Apples (early varieties) — Begin arriving late August. Excellent for apple compote and apple jam (applesauce).

General Summer Preserving Tips
- Buy or pick in small batches — Fresh is always better than bulk-bought fruit that's been sitting for days.
- Process the same day — The moment fruit is harvested, its sugar begins converting to starch and its pectin breaks down.
- Keep your jars ready — Have sterilised jars on standby so you can act the moment produce arrives.
- Keep a preserving notebook — Note the date, batch size, sugar ratio, and any adjustments. This makes next year's batch even better.
