Easy Guide to Fertilizing Strawberries for a Bountiful Harvest

If you want your strawberry plants to thrive and produce a sweet harvest, giving them the right nutrients is key. This simple guide will help you understand when and how to fertilize your strawberries for the best results.

1. Do a Soil Test

Before adding any fertilizer, it’s a good idea to test your garden soil. Soil can lose nutrients over time, and too much fertilizer can be harmful. Use a soil testing kit or contact your local cooperative extension office for accurate results. Aim for a well-draining soil with a pH between 5.3 and 6.5.

2. Best Fertilizer for Strawberries

Strawberries love rich soil, so consider adding compost or aged manure before planting. For ongoing support, a balanced fertilizer like 10-10-10 or 12-12-12 is ideal. If you prefer organic options, choose natural fertilizers such as blood meal, kelp meal, soybean meal, or alfalfa meal. Granular fertilizers are recommended, but liquid fertilizers work well, especially for container-grown strawberries.

3. When to Fertilize Strawberries

  • June-Bearing Strawberries: Fertilize once a year in late summer or early autumn after harvesting. Avoid spring fertilization to prevent soft berries and diseases.
  • Day-Neutral Strawberries: Fertilize when the second flush of flowers appears, and repeat every six weeks until September. Overwintered plants need spring and mid-summer fertilization.

4. How to Fertilize Strawberries in Garden Beds

The amount of fertilizer depends on the type, so follow the package instructions. For granular fertilizers, broadcast around the base and scratch it into the soil with a hand rake. Water it in, ensuring it doesn’t touch plant stems to avoid damage.

5. How to Fertilize Strawberries in Pots

Container strawberries need special care. Consider growing them as annuals, replacing the potting mix and plants each year to prevent diseases. While granular fertilizers can be used, liquid fertilizers are easier for containers. Apply with a sprayer or watering can during regular watering, but be consistent as liquid fertilizers wash out more quickly.

Remember, don’t fertilize late in the season, and follow these tips to ensure your strawberries flourish and provide a delightful harvest.
