Strawberries are easy to grow and by using just a couple of varieties you can be harvesting fresh strawberries throughout the summer and autumn. But to grow strawberry plants that produce an excellent yield of delicious fruits it is important to provide them with nutrient-rich soil full of organic matter and to feed them regularly with an appropriate strawberry fertilizer.
Strawberry Fertilizer: NPK Ratio
Strawberries grow best in fertile, nutrient-rich, slightly acidic soil and they prefer to be fully exposed to the sun. During the early months, most strawberry varieties will benefit from plenty of nitrogen. Nitrogen is essential for all plants and plenty of it will ensure your strawberries develop thick foliage necessary for absorbing light for photosynthesis. Nitrogen can be derived from organic powder fertilisers like bone meal or fish meal, or it can be added using a liquid fertilizer. If you choose to use a liquid fertilizer look for one with an NPK ratio where the first number is the highest, indicating it contains a greater proportion of nitrogen than phosphorus and potassium. After an initial dose of nitrogen-rich strawberry fertilizer switch to a fertilizer rich in potassium and phosphorus. Continuing to supply strawberries with high amounts of nitrogen throughout the growing season will result in too much foliage and not enough fruit. In most cases, changing to a strawberry fertilizer that has a balanced NPK ratio will be sufficient. However, some growers use a potassium-rich fertilizer on their strawberries as they find this works best during the blooming period. To get the best results from your strawberries, use a strawberry fertilizer in combination with plenty of compost in the soil. Strawberries perform best in rich soils that have plenty of organic matter in them. Growing them in compost made from garden waste, manure, or rotted leaves works well.
Strawberry Fertilizer: How To Apply
Regardless of whether you are using a powder fertilizer or a liquid fertilizer, apply it around the base of the plant. Apply both with water to ensure the fertilizer drains into the soil and reaches the roots of the strawberry plants. Fertilize early-fruiting strawberry plants after their last harvest. If you fertilizer in the early spring they will develop too much foliage. For strawberries that produce their fruit later in the season, it is fine to fertilize them at the start of spring. Strawberries that are more than a year old only need to be fertilized once per year. New strawberry plants should be given nitrogen early on followed by a balanced strawberry fertilizer, or a fertilizer rich in potassium and phosphorus, just before they bloom.
