As the weather cools, it’s the perfect time for strawberries to hit the market. Who can resist the allure of large, bright red strawberries? Fortunately, strawberries are not only delicious but also easy to grow, even in a small space like a balcony.

In this article, we will share some tips on how to grow strawberries on your balcony, ensuring you can enjoy a bountiful harvest right at home.

Selecting Strawberry Varieties

Most strawberry varieties are propagated through tissue culture to maintain stable traits, so you can simply buy seedlings. Some types, like alpine strawberries and woodland strawberries, can be grown from seeds. Strawberries come in various types based on ripening time, color, and fragrance.

There are also ornamental varieties like red-flowered strawberries, as well as the aforementioned alpine and woodland strawberries. Choose the ones that suit your preferences.

Planting Strawberries

Strawberry seedlings can be planted in the fall, and it’s not too late to plant now for a winter harvest. In northern regions, planting can also be done from March to May for a summer harvest.

Seeds can be sown in spring and fall (March to May and September to November). Strawberry seeds are tiny, so just press them into the soil. They will germinate in about 10 to 15 days. Once the seedlings have 3 to 4 true leaves, they can be transplanted.

To ensure a good yield and high-quality fruits, the soil for strawberries should be nutrient-rich, loose, and well-aerated, with no pest eggs. You can mix compost with sand, perlite, organic fertilizer, or slow-release fertilizer. If possible, add mediums like akadama soil, pumice, or pine needles to the soil.

The ratio of soil to granular medium should be between 6:4 and 5:5. Besides single planting, multiple plants are often grown in long pots or on vertical growing racks for easy picking and better space utilization. The pot depth should be 18 to 25 centimeters, with a spacing of 15 to 20 centimeters between each plant.

Light Requirements

Ample sunlight is essential for healthy strawberry growth and even fruit coloring. Aim for 6 to 10 hours of direct sunlight daily. However, during the summer, it’s advisable to provide some shade to prevent leaf scorching.

Temperature Control

Strawberries typically ripen in summer, but in the south, where summer temperatures are high, greenhouses are often used to shift the harvest season to winter. When growing strawberries at home, keep the temperature around 10 to 15 degrees Celsius to prevent the plants from entering dormancy, which would delay fruit ripening. You can place the plants indoors or use small greenhouses to maintain the temperature.

Other Management Tips

Under natural conditions, strawberries reproduce through runners. However, due to virus accumulation and variety degradation, this method is generally not used for commercial cultivation as it can reduce yield and quality. Since strawberries do not thrive when grown continuously in the same soil, it’s best to replace the soil and seedlings each year.

For home growers, though, you can experiment with runner propagation. If you don’t plan to propagate, it’s best to remove the runners to prevent them from sapping the plant’s energy. Also, remove any dead leaves that appear during the plant’s natural metabolic process to prevent pest and disease issues. To ensure fruit quality, you can selectively thin out flowers and fruits, retaining only the healthiest strawberries.

With these tips, you can enjoy fresh, home-grown strawberries all season long. Happy gardening, Lykkers!
