The first step in growing delicious strawberries is selecting the right variety. In Britain, there are several types of strawberries to consider, each with its unique characteristics.
- June-bearing Strawberries: In the late spring or early summer, these types yield a single abundant harvest. They are known for their large fruit size and excellent flavor.
- Ever-bearing Strawberries: Throughout the growing season, everbearing strawberries yield two or three minor harvests: in the spring and again in the autumn. When it comes to constant crops, they are fantastic.
- Day-neutral Strawberries: Day-neutral varieties produce fruit continuously from late spring until the first frost. They are less affected by day length and can produce berries throughout the growing season.
When choosing a variety, consider your local climate, soil conditions, and personal preferences. June-bearing strawberries are excellent for making jams and preserves, while ever-bearing and day-neutral varieties provide fresh fruit for longer periods.
Preparing the Soil
We read a few guides and found the Strawberry plants growing guide from Chris Bowers were we learn that strawberries thrive in well-drained, fertile soil rich in organic matter. Proper soil preparation is crucial for a successful strawberry patch.
- Soil Testing: Before planting, conduct a soil test to determine the pH and nutrient levels. Strawberries prefer a slightly acidic soil with a pH between 5.5 and 6.5. Based on the test results, amend the soil as needed to achieve the desired pH.
- Organic Matter: Incorporate plenty of organic matter, such as compost or well-rotted manure, into the soil. This improves soil structure, fertility, and drainage, providing an ideal environment for strawberry plants.
- Raised Beds: Consider planting strawberries in raised beds, especially if your garden has heavy clay soil. Raised beds improve drainage and make it easier to control soil conditions.
Planting Strawberries
The timing and method of planting strawberries are critical for establishing healthy plants and maximizing fruit production.
- Planting Time: In Britain, the best time to plant strawberries is in early spring or autumn. Spring planting allows the plants to establish before the summer heat, while autumn planting gives them time to develop strong root systems before winter.
- Spacing: Proper spacing is essential for healthy growth and high yields. Space strawberry plants 30-45 cm apart in rows spaced 60-90 cm apart. This provides enough room for the plants to spread and ensures good air circulation, reducing the risk of disease.
- Planting Depth: Plant strawberries so that the crown (the point where the leaves emerge) is at soil level. When planting, ensure that the soil is level with the bud union, which is the enlarged area where the canes connect to the rootstock. If you plant too deeply, the roots will rot, and if you plant too shallow, they will dry out.
Watering and Mulching
Proper watering and mulching are essential for healthy strawberry plants and abundant fruit production.
- Watering: Strawberries need consistent moisture, especially during flowering and fruiting. Water the plants deeply once a week, providing about 2.5 cm of water. Avoid overhead watering, which can promote disease. Instead, use a drip irrigation system or water at the base of the plants.
- Mulching: Mulch helps retain soil moisture, suppress weeds, and keep the fruit clean. Use organic mulches such as straw, pine needles, or shredded leaves. Apply a 5-8 cm layer of mulch around the plants, being careful not to cover the crowns.
Fertilizing Strawberries
Strawberries are heavy feeders and benefit from regular fertilization to support their growth and fruit production.
- Pre-plant Fertilization: Before planting, incorporate a balanced fertilizer, such as a 10-10-10 formula, into the soil. This provides essential nutrients to support initial plant growth.
- Post-plant Fertilization: Once the plants are established, apply a balanced fertilizer in early spring and again after the first harvest. Avoid high-nitrogen fertilizers, which can promote excessive leaf growth at the expense of fruit production.
- Organic Fertilizers: Consider using organic fertilizers, such as fish emulsion, seaweed extract, or compost tea. These provide a slow-release source of nutrients and improve soil health over time.
Pest and Disease Management
Strawberries are susceptible to various pests and diseases, but with proper management, you can keep your plants healthy and productive.
- Common Pests: Aphids, slugs, and spider mites are common pests that can damage strawberry plants. Monitor your plants regularly and take action at the first sign of trouble. Use insecticidal soap or neem oil for aphids and spider mites, and handpick or use organic slug pellets to control slugs.
- Disease Prevention: Strawberries can be affected by diseases such as powdery mildew, grey mould, and verticillium wilt. To prevent disease, practice good garden hygiene, such as removing infected plant material, rotating crops, and ensuring good air circulation. Use resistant varieties when possible.
- Organic Control Methods: Consider using organic control methods, such as introducing beneficial insects (ladybirds for aphids) or using copper-based fungicides for disease prevention. These methods help maintain a healthy garden ecosystem and reduce the need for chemical treatments.
Pruning and Renovation
Pruning and renovating strawberry plants are essential for maintaining plant health and maximizing fruit production.
- Pruning: Regularly remove old, yellow, or diseased leaves to improve air circulation and reduce disease risk. After the harvest, cut back the foliage of June-bearing varieties to about 10 cm above the crowns to encourage new growth.
- Renovation: Every few years, it’s necessary to renovate your strawberry patch to rejuvenate the plants. For June-bearing strawberries, renovate after the last harvest by mowing or cutting back the plants to just above the crowns, thinning out excess runners, and applying a balanced fertilizer. This encourages vigorous new growth and improves yields in subsequent seasons.
Extending the Growing Season
To enjoy fresh strawberries for as long as possible, consider techniques to extend the growing season.
- Succession Planting: Planting different varieties with varying harvest times can extend the strawberry season. Combine early, mid, and late-season varieties to ensure a continuous supply of fruit from late spring to autumn.
- Protective Structures: Use cloches, row covers, or polytunnels to protect strawberry plants from frost and extend the growing season. These structures create a microclimate that allows for earlier planting and later harvesting.
- Container Gardening: Growing strawberries in containers is another way to extend the season. Containers can be moved to a sheltered location or greenhouse to protect the plants from adverse weather conditions and extend the harvest period.
Harvesting and Storing Strawberries
Knowing when and how to harvest strawberries is crucial for enjoying the best flavor and quality.
- Harvest Timing: Pick strawberries when they are fully ripe for the best flavor. Ripe strawberries are fully red, with no white or green areas near the stem. Harvest in the morning, when the berries are cool, for the best flavor and shelf life.
- Harvesting Technique: Use scissors or snip the stem just above the berry to avoid damaging the fruit and plant. Handle the berries gently to prevent bruising.
- Storing Strawberries: Strawberries are best enjoyed fresh but can be stored in the refrigerator for a few days. Do not wash the berries until you are ready to eat them, as excess moisture can cause them to spoil quickly. For longer storage, consider freezing, making jam, or dehydrating the berries.
Propagating Strawberries
Propagating strawberries allows you to expand your strawberry patch or share plants with friends and family.
- Runner Propagation: Strawberry plants produce runners, or stolons, which develop into new plants. To propagate, select healthy runners and peg them down into the soil or a small pot filled with compost. Once the new plants have developed roots, sever the runner from the parent plant and transplant to a new location.
- Division: Mature strawberry plants can be divided to create new plants. Dig up the plant and gently separate the crowns, ensuring each division has a healthy root system. Replant the divisions immediately.
Tips for Container Gardening
If you have limited garden space or prefer a more flexible growing option, consider growing strawberries in containers.
- Container Selection: Choose containers with good drainage, such as pots, hanging baskets, or strawberry planters. Ensure the containers are at least 20 cm deep to accommodate the root system.
- Soil Mix: Use a high-quality potting mix enriched with compost or well-rotted manure. Avoid using garden soil, which can become compacted and reduce drainage.
- Watering and Fertilizing: Container-grown strawberries dry out more quickly than those in the ground. Ensure regular and thorough watering, maintaining the soil’s moisture at a steady level without causing waterlogging. Apply a well-balanced fertiliser every 3-4 weeks throughout the period of active growth.
- Sunlight and Placement: Place containers in a sunny location, receiving at least six hours of direct sunlight daily. If growing indoors, use grow lights to provide adequate light for the plants.
Troubleshooting Common Issues
Even with the best care, you may encounter some challenges when growing strawberries. Here are common issues and how to address them:
- Poor Fruit Set: If your strawberry plants produce flowers but few fruits, it could be due to poor pollination. Encourage pollinators by planting flowers nearby and consider hand-pollinating flowers with a small brush.
- Small or Misshapen Berries: Inconsistent watering, nutrient deficiencies, or pest damage can cause small or misshapen berries. Ensure regular watering, provide balanced fertilization, and monitor for pests.
- Leaf Yellowing: Yellowing leaves can indicate various issues, including nutrient deficiencies, overwatering, or disease. Conduct a soil test to check for nutrient imbalances and adjust your watering practices.
- Moldy Berries: Grey mould (Botrytis) can cause berries to become mouldy. Improve air circulation around the plants, avoid overhead watering, and remove any affected berries immediately.
Maximizing Yield
To maximize your strawberry yield, follow these additional tips:
- Rotate Crops: Rotate your strawberry plants to a new location every three to four years to prevent soil-borne diseases and maintain soil fertility.
- Manage Runners: Control the number of runners to focus the plant’s energy on fruit production. Remove excess runners or use them for propagation.
- Support the Plants: Use stakes or plant supports to keep the fruit off the ground, reducing the risk of disease and ensuring cleaner berries.
- Regular Harvesting: Harvest berries regularly to encourage continuous fruiting and prevent overripe berries from attracting pests.
Sustainable Practices
Incorporating sustainable practices into your strawberry growing routine can benefit both your garden and the environment.
- Organic Methods: Use organic fertilizers and pest control methods to reduce chemical inputs and promote a healthy garden ecosystem.
- Water Conservation: Implement water-saving techniques, such as mulching and drip irrigation, to conserve water and reduce evaporation.
- Companion Planting: Grow strawberries alongside companion plants, such as marigolds or garlic, which can help deter pests and improve plant health.
- Wildlife Habitats: Create habitats for beneficial wildlife, such as bees and birds, which can aid in pollination and pest control.
Winter Care
Proper winter care ensures your strawberry plants survive the cold and emerge healthy in the spring.
- Mulching: Apply a thick layer of mulch, such as straw or pine needles, over the strawberry bed in late autumn to protect the plants from frost. Remove the mulch in early spring as new growth begins.
- Container Plants: Move container-grown strawberries to a sheltered location, such as a garage or greenhouse, to protect them from severe cold. Water sparingly during the winter months.
- Cold Frames: Use cold frames or cloches to provide extra protection for strawberry plants during the winter. These structures can help maintain a more stable temperature and protect plants from harsh weather.
