What Type Of Strawberries Should I Grow?
The type of strawberries you choose to grow may depend on the resources you have available and may affect the way you raise your plants. There are three main types of strawberry plants:
- Summer-fruiting: Typically the most popular strawberry variety because they produce large fruit in bumper crops from early to mid summer. Examples of summer-fruiting strawberries include Honeoye, Sweetheart and Cambridge Favourite
- Perpetual-fruiting: Producing small crops of fruit over a long period, often from spring until the first frost, perpetual-fruiting strawberries don’t require as much growing space as their summer-fruiting relatives. Examples of perpetual-fruiting (or ‘everbearing’) strawberries include Flamenco, Aromel and Balero
- Alpine: Sometimes referred to as ‘wild’ or ‘woodland’ strawberries, Alpine strawberry plants produce smaller and sweeter berries than other varieties and so are well suited to growth in containers, pots, or baskets. Examples of Alpine strawberries include Mignonette, Baron, Solemacher, and Scarlet Wonder
If you plant a variety of different strawberries, you’ll be able to grow and harvest your fruit over a longer period of the year
When To Plant Strawberries
The best time to plant strawberries is going to vary depending on where you live, and the local climate. In Britain, for harvest the following year, the window for planting strawberries runs from mid-spring through to early Autumn - mid-September at the latest in southern regions. The earlier you plant your strawberries, the longer their roots will have to establish before the heat of summer kicks in
Of course, if you have a greenhouse, and the ability to control the temperature of that environment, you could grow strawberries all year round
Where To Plant Strawberries
One of the most attractive things about growing strawberries is their flexibility: strawberries can grow in gardens, plant pots, hanging baskets - or anywhere you have space. Ideally, you’ll find a position where your strawberry plants can get a lot of sun, are sheltered from wind and birds, and where their fruit can be picked easily at harvest. Avoid growing your strawberries in spots that get a lot of frost because the cold might damage any early flowering varieties
If your growing spot doesn’t get a lot of sunlight, don’t worry: you could opt for Alpine strawberries is that actually do better in a bit of shade
Planting Your Strawberries
You’ve decided on a type, and chosen a location for your strawberries - now it’s time to think about how you’re going to plant them
How To Grow Strawberries In The Ground
If you’re planting your strawberries in the garden, make sure you’re using slightly acidic soil - or enhance the acidity of the soil by digging in compost or organic fertiliser beforehand. You’ll need to dig a hole for each strawberry plant, spaced around 40 cm apart in rows 100cm apart so they have enough room to flourish, You can enhance the drainage by planting the strawberries in slightly raised beds
Once your plants are placed, push the soil back over and around them. Make sure the crown of your strawberry plant isn’t below the surface of the soil or the moisture might cause it to rot. When they’re bedded in, water the area around your plants thoroughly
How To Grow Strawberries In Pots
You can grow strawberries in a variety of largecontainers, including plants pots, hanging baskets and window baskets, or even growing bags.
Fill your container with peat free multi-purpose compost and plant your strawberries the same as you would when planting in the ground. Leave around 20cm of space between each plant. Water your compost regularly, and check that it doesn’t get dry in hot weather
How To Grow Strawberries From Seeds
Alpine strawberries can be grown from seed indoors, although the process is difficult and takes a lot of time and effort – we recommend growing your strawberries from runners or plants
If you do decide to start your strawberries from seeds, you’ll need to ensure the germination process has begun before you put them in the ground, or in your container - a process that can take over a month
Sow your seeds indoors in the autumn or spring by scattering them thinly into seed trays. Make sure they’re kept moist and get a lot of heat and light. Ideally, you should start with a seed tray, and a heating lamp set at around 18 to 20 degrees - and then move the plants to the ground or a container when they grow too big to maintain in the tray
How To Plant Strawberry Runners
Most varieties of strawberry plant produce runners, also known as ‘stolons’, which are stems that grow horizontally and run along the ground - producing new plants from nodes along their length. Plants from strawberry runners produce their own roots: when these roots are established in their own soil, the runners can be cut from the main plant and should begin to grow on their own - at which point you can move them to a new location
By cultivating runners from your healthiest or best-tasting strawberries, you’ll be able to propagate new plants that share those qualities. If you’re going to propagate your strawberry plants this way, remember to use nutrient-rich, composted soil, and be careful when (or if) you move them to a new spot to grow
The best time to plant your runner plants is probably in mid to late summer. Make sure they’re established in the ground before the first frost to protect them from the effects of the cold
How Long Do Strawberries Take To Grow?
Strawberries are such a rewarding fruit to grow because of the relatively short time it takes for them to mature It usually takes around four months for a strawberry to grow from a seed to a berry-producing plant. That timescale is obviously dependent on certain environmental conditions, including temperature, light exposure, access to water, and the quality of the soil
You can track your strawberry plant’s growth through the following phases:
Seedling - 0 to 8 weeks: If you’re growing from seeds you’ll need to plant about 8 weeks before the first frost. You should start to see leaves forming from around 2 weeks of growth
Vegetative - 8 to 12 weeks: In the vegetative phase, healthy strawberry plants start to form lots of green foliage
Flowering - 12 to 14 weeks: Following the development of foliage, you’ll start to see flowers - which could eventually become strawberries. Many owners opt to remove flowers during the first year of growth so that the roots and foliage can flourish, and that the plant becomes stronger in the long term. Strawberry flowers are edible, so if you do prune them, you could throw them in a salad
Fruiting - 14 weeks onward: After strawberry flowers are pollinated successfully, fruit should develop. Strawberry fruits are usually white when they first develop but then swell in size over the next couple of weeks and turn a bright, rich red. Once that happens, they’re ready to pick and eat!
How To Look After Strawberry Plants
Growing strawberries shouldn’t monopolise your gardening time, but you will need to keep an eye on them to make sure they stay healthy:
- Water your strawberries regularly to keep them moist. Try to direct the water to the plant itself so that the leaves don’t mould
- Feed your strawberries regularly - once a week or once a fortnight is usually a suitable schedule. Use a high potassium feed (such as tomato feed) to encourage flowering
- Place a mat around your plants before fruit starts to develop to protect the berries from slugs and snails, and consider using netting to protect from small birds or mammals
- Trim runners in the first year of growth to help your plants conserve energy and nutrients, and to encourage the development of healthy fruit
- After three or more years of growth, it might be necessary to replace your strawberry plants - you might consider using runners to propagate new plants
Strawberry Plant Problems to look out for
It’s worth being aware of some of the most common problems that affect strawberry plants’ growth, and what you can do to fix them:
Grey mould:. Try to keep the fruit dry when watering your plants, and water them in the morning so they have time to dry out during the day. It may also help to keep the soil around your strawberry plants free from debris since the fungus spreads on plant matter
Verticillium wilt: It’s difficult to cure verticillium wilt once it takes hold, so prevention is the best cure - and you should remove plants if you spot an infection
Mildew: If you spot mildew, prune any affected leaves, and remove weeds from around the plant
Vine weevil: The best option for dealing with weevil is to apply a biological vine weevil solution
Frost: If you’ve planted strawberries in spring, they may still be susceptible to a late frost which can damage their growth. Protect strawberry plants from frost by covering them with pots, or placing a layer of gardening fleece over them
When To Pick Strawberries
Most strawberry fruits turn from white to red as they ripen. When the fruit is bright red all over, and looks juicy, it’s ready to be harvested. It’s worth harvesting strawberry fruit as soon as they ripen - because this is when they taste best!
Harvesting strawberries is easy. Since you can pick them by hand, all you’ll need is a container to hold them. Take the stalk holding the fruit between two fingers, and pinch the fruit free, taking care not to bruise or blemish it. Give your strawberry fruits a wash, and they’re ready to eat - although you can store them in the fridge for a few days if necessary
What To Feed Strawberry Plants
In early spring, as your strawberry plants are growing in the ground, you should scatter high potassium fertiliser around them to encourage healthy growth. If you’re growing your strawberries in containers, use a liquid feed. Use a high potassium feed, such as tomato feed, that will help them flower
Are Strawberry Plants Perennial?
Strawberries are perennial, which means their above-ground portion will die off in winter but then grow back as the weather warms up, bearing fruit year after year. You might find that some strawberry plants take a growth break towards the end of summer, and then grow again in autumn
After 2 or 3 years, you’ll find your plants become a little less productive - which is a sign you should replace them or propagate them through runners
