There’s nothing quite like opening a jar of homemade strawberry jam made from fruit you grew yourself.
Freshly picked strawberries have a sweeter flavour, stronger aroma and softer texture than many supermarket varieties, making them perfect for preserving. Better still, strawberries are one of the easiest fruits to grow, even if you only have a patio, balcony or a few containers.
Whether you’re hoping to make a single batch of jam or enough to fill your pantry, here’s everything you need to know about growing strawberries for preserving.
Why Homegrown Strawberries Make Better Jam
Growing your own strawberries gives you control over exactly when the fruit is picked.
Unlike shop-bought strawberries, which are often harvested before they’re fully ripe, homegrown berries can stay on the plant until they’re perfectly sweet and full of flavour.
That extra ripeness makes a noticeable difference when you’re making jam.
Homegrown strawberries also tend to have a stronger aroma and richer colour, creating a preserve that’s bursting with summer flavour.
Choose the Right Strawberry Variety
Not all strawberries crop in the same way.
For jam making, think about how much fruit you’d like to harvest at once.
June-bearing strawberries
These produce one large crop over a few weeks, making them ideal if you want enough fruit for several jars of jam in one go.
Everbearing strawberries
These fruit little and often throughout the summer.
They’re perfect if you enjoy fresh strawberries as well as making smaller batches of jam.
Where to Grow Strawberries
One of the reasons strawberries are so popular is that they’re incredibly versatile.
They grow happily in:
- Garden borders
- Raised beds
- Containers
- Hanging baskets
- Strawberry planters
- Window boxes
If you’re short on space, containers often make harvesting easier and help keep fruit cleaner.

Give Them Plenty of Sunshine
Strawberries produce their sweetest fruit in full sun.
Aim for at least six hours of direct sunlight each day.
Plants grown in too much shade often produce fewer berries, and the fruit may not be as sweet.
Choose the Right Soil
Strawberries like fertile, well-draining soil that’s rich in organic matter.
If you’re growing them in containers, use a good-quality multi-purpose compost and ensure your pots have drainage holes.
Avoid leaving plants sitting in water, as soggy roots can quickly rot.
You’ll Need
Water Consistently
Regular watering is one of the biggest secrets to producing juicy strawberries.
Allowing plants to dry out between watering can reduce fruit size and affect flavour.
Water the soil rather than the leaves whenever possible to reduce the risk of fungal diseases.
Feed for Bigger Harvests
Strawberries are hungry plants.
Once flowers begin to appear, feed every week or two using a fertiliser designed for fruiting plants.
Many gardeners successfully use tomato feed (yes really!) because it’s high in potassium, helping encourage flowers and fruit.
You’ll Need
Protect Your Crop
You’re not the only one who loves strawberries.
Birds, slugs and snails are all keen to enjoy your harvest too.
Simple netting can stop birds reaching the fruit, while straw placed beneath ripening berries helps keep them clean and reduces the risk of rot.
You’ll Need
Harvest at the Perfect Time
The best strawberries for jam are fully ripe but still firm.
Pick them during dry weather if possible, ideally in the morning after any dew has dried.
Use the fruit as soon as possible after harvesting for the freshest flavour.
If you’ve picked more than you need, simply freeze the berries until you’re ready to make jam.
How Many Plants Do You Need?
The answer depends on how much jam you’d like to make.
As a rough guide:
- 6–8 plants provide plenty of fresh eating.
- 15–20 plants can produce enough fruit for several batches of homemade jam.
- Larger beds allow you to preserve throughout the summer.
Remember that strawberry plants also produce runners, allowing you to create new plants for free.
Equipment You’ll Need
Growing strawberries is simple, but a few tools can make the job even easier.
Recommended Equipment
- Strawberry plants
- Strawberry tower planter
- Hanging baskets
- Multi-purpose compost
- Tomato feed
- Watering can
- Garden netting
