Growing strawberries at home can be a rewarding and enjoyable gardening experience. These popular fruits are not only delicious but also rich in vitamins, antioxidants, and other essential nutrients. By understanding the basics of how to grow strawberries, home gardeners can add this healthy and tasty fruit to their gardens with ease.
Strawberries can be grown from seeds or transplanted from existing plants, with the latter being a more straightforward approach for beginners(source). These plants require adequate spacing, usually around 12-18 inches apart, to allow room for runner growth and better air circulation (source). With proper care in terms of light, water, soil, and mulching, strawberries will thrive and yield an abundance of fruit for years to come (source).
Choosing the Right Variety
When growing strawberries, selecting the appropriate variety is crucial for a successful harvest. Strawberry varieties can be grouped into three main categories: June-bearing, everbearing, and day-neutral.
June-Bearing
June-bearing strawberries are the most common type and are known for producing fruit during a three to four week period in early to mid-June in most regions [source]. These plants form flower buds in the fall as the day length decreases, making their harvest timing predictable. To ensure a steady supply of fruit throughout the season, consider planting early-season, mid-season, and late-season varieties of June-bearing strawberries [source].
Everbearing
Everbearing strawberries produce small, intermittent harvests throughout the growing season. These plants do not depend on day length variation to initiate flowering, unlike June-bearing strawberries. Everbearing varieties can provide a continuous harvest for gardeners seeking a consistent supply of fresh strawberries throughout the season [source].
Day-Neutral
Day-neutral strawberries are similar to everbearing varieties, as they also produce fruit throughout the growing season. However, day-neutral plants are less affected by environmental factors such as temperature and daylight length. This can make them an excellent choice for gardeners in zones 9-10, where fluctuating temperatures and day lengths can impact the production of other strawberry varieties.
One example of a day-neutral variety is the alpine strawberry (Fragaria vesca). Alpine strawberries are known for their small, flavorful fruits and their adaptability to different growing conditions [source]. When selecting a strawberry variety to grow, consider the climate, growing season length, and your personal preferences for fruit production.
Site Selection and Soil Preparation
Garden Location
Choosing the right location for your strawberry garden is crucial for optimal growth and fruit production. It is essential to select a site with full sun exposure, as strawberries require 8 to 10 hours of sunlight each day for ideal growth (WikiHow). Ensure the selected area has well-drained, loamy soil, to maintain plant vigor and reduce the risk of disease (UMN Extension). Additionally, positioning the berry beds on fairly level ground with a gentle slope of 2-3% can improve air circulation around the plants (UMN Extension).
Soil Testing
Prior to planting your strawberries, it is highly recommended to conduct a soil test. This will provide valuable information about the soil’s pH, nutrient levels, and any possible imbalances. Strawberries prefer slightly acidic soil with a pH between 5.5 and 6.5. If the soil pH is outside this range, you can amend it for optimal strawberry growth.
Soil Amendments
Once the soil test results are available, evaluate the necessary amendments to create well-draining, fertile soil for your strawberry plants. One approach is to incorporate dehydrated cow manure, garden compost, or peat moss (up to 1/3 concentration) into the topsoil to loosen the soil quality (Stark Bro’s). Straw mulch is another helpful addition; it helps suppress weeds, moderate soil moisture, and prevent berries from coming in direct contact with the soil (Better Homes & Gardens).
When planting the strawberry rows, consider incorporating the runner system to maximize fruit production. Space the rows approximately 4 feet apart, and plant individual plants within the rows about 18 to 24 inches apart. Timing is crucial; plant your strawberries in early spring, after the risk of the first frost has passed for optimum growth in your home garden.
Planting and Spacing
In-Ground Planting
Before planting strawberries, choose a well-drained site with plenty of direct sunlight. Prepare the soil by loosening it and adding compost or other organic matter to improve fertility. Dig holes deep enough to accommodate the roots of the strawberry plants, usually about 12-18 inches apart, and 4 feet between rows, which will allow for proper air circulation and runner development. UMN Extension and The Old Farmer’s Almanac both provide guidelines for planting spacings.
When placing the plants into the holes, make sure the roots are spread out and not coiled. Fill the holes with soil and firm it around the plants, ensuring that the crown – the point where the stem and the roots meet – is slightly above the soil line. Water the plants thoroughly after planting to help the roots establish contact with the soil.
Container Planting
Strawberries can also be grown in containers, which is an excellent option for those with limited space or who want to add a decorative touch to their garden. When selecting a container, choose one with drainage holes and ensure that it is large enough to hold the roots and provide room for growth.
Fill the container with a high-quality potting mix and plant the strawberries following the same spacing guidelines as for in-ground planting. Place the containers in an area that receives at least 6-8 hours of sunlight per day, and water regularly to maintain moist but well-drained soil. Better Homes & Gardens also offer tips on container planting.
Watering and Fertilization
Water Requirements
Strawberries require consistent moisture throughout the growing season. Providing 1 to 2 inches of water per week is essential for a healthy crop, and maintaining well-drained soil helps prevent root rot. A drip irrigation system can be an effective way to ensure that the plants receive the required moisture while minimizing water wastage.
It is important to keep the soil evenly moist, especially during periods of fruit development. However, overwatering can lead to disease and reduced fruit quality. In addition, avoid splashing water on the foliage, as this can encourage the spread of diseases.
Nutrient Management
A successful strawberry crop relies on a well-balanced nutrient regime. Strawberries thrive in rich, loamy soil with plenty of organic matter, such as compost or well-rotted manure. Prior to planting, incorporate organic matter into the soil to improve fertility and drainage.
Fertilization of strawberries should be carefully planned, as over-fertilization can harm the plants. For June-bearing varieties, apply nitrogen (N) at a rate of 0.30 ounces per 10 ft of row six weeks after planting, and again in August. For all types, ensure that the soil pH is around 6.0.
Mulching plays a vital role in maintaining soil moisture and temperature. Using straw mulch helps to retain moisture and prevents soil from splashing onto the plants. Additionally, mulching suppresses weed growth and prevents nutrient competition.
Pest and Disease Control
For successfully growing strawberries, it is important to properly manage pests and diseases. This section of the article will briefly discuss the methods for controlling insect pests, fungal diseases, and other issues that may affect strawberry plants.
Insect Pests
Insects like bugs and slugs can damage strawberry plants and cause reduced vigor, as well as impacted fruit production. To manage potential insect pests, consider the following approaches:
- Choose a suitable site for your strawberry plants to reduce pest pressure. Ensure the location receives adequate sunlight and does not have excessive shade from trees or buildings.
- Regularly monitor your plants for signs of pests and take action early to limit their impact on your strawberries.
- Use natural or chemical control methods, such as Safer® Brand Insect Killing Soap, to manage pest infestations.
Fungal Diseases
Fungal diseases such as powdery mildew and anthracnose can be common in strawberry plants, affecting both leaves and fruits. These fungi thrive in cold temperatures and can cause excessive leaf growth, ultimately reducing the yield. To manage and prevent fungal diseases:
- Regularly inspect your strawberry plants for signs of fungal growth or disease symptoms, such as lesions, discoloration, or distorted leaves.
- Manage the humidity and moisture around your strawberry plants by providing proper ventilation and avoiding overwatering which can lead to fungal growth.
- Apply preventive treatments such as fungicides, either organic or synthetic, to keep fungal diseases at bay.
By implementing the measures mentioned in the above sub-sections, you can successfully control common pests and diseases that affect strawberry plants. This will ensure a healthy and productive garden for growing delicious and nutritious strawberries.
Maintaining Strawberry Plants
Pruning and Runners Management
Proper pruning is essential for healthy strawberry plants. Remove any dead or yellowing leaves as they appear throughout the growing season to maintain good air circulation and prevent disease.
Management of runners is also important. Runners are horizontal stems that grow away from the mother plant and produce new plants. Allow only a few runners per plant to develop, as this will ensure the new plants receive adequate resources to grow. As a rule, choose the most vigorous runners for propagation and remove the rest. Peg chosen runners into pots filled with multi-purpose compost or directly into the ground, and remove secondary runners that grow from them. This technique can be essential for successful development of new strawberry plants, as mentioned by Which?.
Overwintering Care
Strawberry plants need attention during winter to protect them from harsh weather conditions. Strawberry varieties such as Tristar may require special overwintering care, like covering the rows outdoors with fleece or using straw mulch. Weeds should also be removed throughout the season to ensure better drainage and reduce competition for nutrients. For container-grown plants, ensure there is a drainage hole at the bottom of the pot to prevent waterlogging.
Rejuvenation
Rejuvenation of strawberry plants is crucial for maintaining a bountiful harvest year after year. One common approach is the matted row system, where plants are allowed to grow and produce runner plants in rows. At the end of the season, remove the mother plants, and the most vigorous runner plants will remain, ensuring your garden continues to produce a healthy crop in coming years.
Another important practice for rejuvenating strawberry plants is mulching with materials like straw or pine needles. Mulching helps retain moisture, suppress weeds, improve soil structure, and insulate the roots during extreme temperatures. Applying straw mulch around the plants before winter and after the initial harvest helps in maintaining the health and vigor of the plants, as mentioned by Royal Horticultural Society.
Harvesting and Storage
Successfully growing strawberries requires not only proper planting and care but also attention to harvesting and storage. Properly harvesting and storing strawberries will ensure fruit remains fresh and delicious.
When to Harvest
Knowing the right time to harvest strawberries is crucial to getting the best flavor and texture. Strawberries should be picked when they are fully ripe, which is when they are bright red all over. Look for strawberries that are firm, plump, and shiny. Grower Experts advises to avoid strawberries that are soft, mushy, or have mold on them.
It’s important to note that fruit production may vary based on the strawberry variety, planting conditions, and climate. Harvesting typically occurs from spring to early summer, and small fruit may be a result of inadequate watering or fertilization.
How to Store
Once you have harvested your strawberries, proper storage is essential for maintaining freshness. Follow these simple steps to store your strawberries:
- Rinse strawberries gently, but briefly. Prolonged exposure to water leads to a mushy texture and a less appealing appearance.
- Remove any damaged or overripe berries to prevent spoilage.
- Let strawberries air dry on a paper towel or a clean cloth.
- Arrange strawberries in a single layer on a tray or plate, making sure they don’t touch one another.
- Store the tray or plate in the refrigerator. Strawberries typically last 3-7 days in the fridge, depending on their freshness.
For longer storage, consider freezing strawberries for future use. Simply follow the steps above but place them on a baking sheet or tray and put them in the freezer. Once frozen, transfer the strawberries to a freezer-safe container or bag, and store them in the freezer for up to 6 months.
