Everbearing strawberries – how to effectively extend the harvesting season?

Strawberries are among the most popular fruits in Polish gardens. They are associated with the beginning of summer, a sweet taste, and homemade desserts. However, classic strawberry varieties bear fruit for a relatively short time—usually for 3–4 weeks in June. For those who would like to enjoy fresh fruit for much longer, everbearing strawberries are the perfect solution. With proper care, they can produce crops from June all the way until autumn. How can this be achieved? The key lies in choosing the right variety and high-quality strawberry plants, as well as providing proper care.

What are everbearing strawberries?

Everbearing strawberries, also known as remontant or day-neutral varieties, are types that form flower buds regardless of day length. As a result, they fruit several times during the season, in so-called waves. The first fruits usually appear in June, the next in mid-summer, and the last even in September or October, if weather conditions are favourable.

Popular varieties of this type include Albion, San Andreas, Selva, Ostara, and Mara des Bois. They are characterised by good flavour, an intense aroma, and suitability for cultivation both in the ground and in containers.

Choosing the right location

For strawberries to bear fruit over a long period, they must grow in suitable conditions. The most important factor is sunlight—at least 6–8 hours of sun per day. The more light, the better the flowering and the sweeter the fruit.

The soil should be:

• fertile,
• rich in organic matter,
• slightly acidic (pH 5.5–6.5),
• well-drained, so that water does not stagnate around the roots.

Before planting, it is worth enriching the soil with compost or well-decomposed manure. This is an investment that will pay off with longer and more abundant fruiting.

Regular watering – the foundation of success

Strawberries have a shallow root system, which makes them sensitive to water shortages. Irregular watering results in small fruits and breaks in production. It is best to:

• water frequently but moderately,
• avoid drying out the soil,
• avoid wetting the leaves and fruit.

Mulching is very helpful—using straw, bark, sawdust, or agrotextile. This helps the soil retain moisture longer, keeps the fruit clean, and reduces susceptibility to diseases.

Fertilisation – fuel for long fruiting

Everbearing strawberries require more nutrients than single-cropping varieties.

Regular fertilisation is crucial so that the plant has enough energy for successive waves of flowering and fruiting.

It is best to use:

• fertilisers dedicated to strawberries,
• biohumus,
• organic fertilisers (compost, granulated manure),
• fertilisation every 2–3 weeks during the season.

It is important not to overdo nitrogen, as excess nitrogen leads to lush leaf growth at the expense of fruit.

One of the most common mistakes in growing everbearing strawberries is leaving runners. Although they are useful for plant propagation, they weaken fruiting by diverting energy needed for fruit development.

If you want a long harvesting season:

• regularly remove runners,
• leave them only if you plan to propagate plants.

It is also worth removing old, diseased leaves and spent flower stalks. This improves air circulation around the plants and limits the development of fungal diseases.

Growing in containers and under cover

Everbearing strawberries are ideal for growing in pots, balcony boxes, and hanging containers. This form of cultivation has an additional advantage—mobility. On cooler days, plants can be moved to a more sheltered place.

Even better results can be achieved by growing them in a foil tunnel or greenhouse. Covers:

• speed up the first harvests,
• protect against rain and cold,
• allow the season to be extended by several weeks.

In autumn, it is enough to cover the plants with agrotextile to harvest fruit until the first frosts.

Protection against diseases and pests

Long fruiting is only possible when plants are healthy. Preventive measures are worth applying:

• avoid excessive plant density,
• do not water over the leaves,
• remove infected fruit.

Natural sprays, such as those made from nettle, horsetail, or garlic, are a good solution. They strengthen plant resistance and limit disease development.

Do everbearing strawberries have any disadvantages?

Like any crop, they also have some downsides. Fruit from later harvests may be slightly smaller, and plants require more attention and regular care. In return, however, we gain continuous fruiting, fresh fruit for several months, and the ability to harvest exactly when we feel like it.

Summary

Everbearing strawberries are an excellent choice for anyone who wants to maximise the harvesting season. Proper location, regular watering, fertilisation, and removal of runners allow plants to bear fruit from June until autumn. This is an ideal solution both for gardens and for balconies or terraces.
