Who doesn’t love strawberries? Perfect as part of a colourful summer fruit salad, a healthy morning smoothie, a vibrant Eton mess, or as that old English favourite, strawberries and cream.
If you’re a strawberry fan, the many varieties of ‘Fragaria × ananassa’, are easy to grow at home, allowing you to enjoy the perks of harvesting ripe fruits in your own garden. What all strawberry growers will soon realise – you’ll be having the juicy fruit with everything, as just one plant can be a prolific cropper.
Understanding the different types of strawberry
Strawberries are either summer-bearing or everbearing.
Summer-bearing strawberries tend to grow bigger fruits and produce one larger harvest over a two-week period in the summer. The exact timing depends on the cultivar. These larger harvests are ideal if you plan to make jam with your strawberries, as you will require a glut of fruit in order to do this.
Everbearing plants, also called perpetual strawberries, produce fruit all season, but in smaller numbers and more sporadically. This type of strawberry is ideal to snack on fairly regularly, or for small harvests to enjoy at breakfast for example.
It’s also worth mentioning the alpine, or wild strawberry, Fragaria vesca. Technically an everbearing strawberry, it also does well in gardens. The fruits are small and a bit dry but with an intense flavour. They spread easily and make excellent groundcover, which is another perk as the dainty leaves are ornamental.
When to plant your strawberries
Strawberries are available as bare-root runners, that are best planted in the spring or as young plug and potted plants.
You can plant strawberries at any time of the year, as long as the soil is workable and not waterlogged or frozen. However, mid-spring or early autumn are the ideal times to plant strawberries for an effective and bountiful harvest.
How to plant strawberries
So, you love the taste of strawberries. You’re ready to have them with everything, but your big question is. How to grow strawberries? The great news is that strawberries are simple and straightforward to grow. You do need to make sure you follow some basic guidelines though. Here’s how to do it.
A thorough examination
The first step is to examine your plants prior to planting. Check them for signs of pests and disease and remove any damaged leaves with clean tools. If your new plants are on the small side, you may choose to remove any early flowers or immature fruits. This will encourage the plant to put its energy into producing fresh growth, giving it a better chance of producing higher yields in the summer.
Choosing where to grow them
When left to their own devices, strawberries may become very invasive, which is why many gardeners prefer to grow them in containers. Traditional strawberry planters are specialised containers that allow multiple plants to be grown in a small amount of space. Strawberries grow well in most containers and hanging baskets, as long as drainage holes are present. Try a multipurpose compost as a growing medium and space the strawberries about 20cm (8in) apart.
When planting strawberries, try a sunny location as they fruit well in full sun. They will tolerate part-shade, although fruit yields may be smaller. Strawberries like fertile but well-drained soil. If you are planting them directly in the ground or a raised bed, it’s worth incorporating some manure or general fertiliser into the soil before planting. Space the plants 30-45cm (12-18in) apart, in rows 60-90cm (24-36in) apart
Planting your strawberry plants
Using a trowel, dig a planting hole twice as large as the plant’s root ball. Make sure the plant’s crown, where the leaves meet the roots, is level or ever so slightly proud of the compost surface. Planting strawberries too deep can lead to rot, and planting too high will dry the roots out. Backfill around the plant’s roots and firm down the soil with your hands.
The final stage is optional but certainly helpful. Add a thin layer of straw to the surface of the soil and around the strawberry plants. If straw isn’t available, you can use horticultural grit. This acts as a barrier between the developing fruit and the soil. Fruits resting against the soil surface are vulnerable to rot if the soil is wet, and nibbles from hungry insects.
When to harvest strawberries
You are likely to know when to harvest strawberries as the fruits will have darkened in colour and look juicy. Try to harvest as soon as they are ripe, as this is when they taste their best. Remember to be as gentle as possible when harvesting as this prevents bruising to the fruit. If you can, remove the stalk and stem from the plant too.
How to care for your strawberries
Strawberry plants require some light maintenance to keep them healthy and productive. The first tip is to water regularly, especially if the plants are growing in a container or raised bed. When watering, aim the flow near the base of the plant, rather than overhead, as the leaves of strawberries can be susceptible to moulds when wet.
Regular fertilising is also important when growing strawberries, as they are heavy feeders. Most gardeners like to use a high-potash liquid feed every two weeks, such as Miracle-Gro Performance Organics Fruit & Veg feed. This kind of feed encourages flowering; and more flowers means more fruit. If strawberry feed is unavailable, tomato feed will do the job well.
Be aware that you may not be the only lover of fresh strawberries in the garden. Birds, slugs, snails and other insects enjoy them too. Many gardeners create a netting shield around their strawberries to stop the birds getting to them. Containers of strawberries placed on high surfaces can help deter slugs and snails. If you are growing strawberries in the ground, you may wish to use copper rings to discourage slugs or snails, or put down slug pellets, although make sure they are pellets that are certified as safe to use near edible plants.
It’s worth remembering that strawberry plants eventually lose their vigour and usually need replacing every three to four years. In the second or third year, you may decide to propagate baby plants from the runners your strawberries produce. These are the long creeping shoots that snake along the soil and produce daughter plantlets nearby.
However, in the first year, it’s beneficial to remove runners as and when you see them. Cut them off where they meet the mother plant. This encourages your strawberry plants to put more energy into flowering and fruiting.
By following these simple and straightforward steps, you’ll have a bumper harvest of strawberries in no time. How you make the most of this delicious fruit is up to you.
