Proper fertilization of strawberries is the key to rich and healthy crop. Strawberries need a balanced supply of nutrients that can support the growth of plants and the quality of the fruit. Read how to choose the best fertilizer for your strawberries and when to use it best.
Strawberries are among the most popular fruits that we like to enjoy fresh in the form of jam, cakes or desserts. However, in order to produce large and tasty fruits, they need enough nutrients in the soil. Too many or few nutrients can lead to weakening of plants, lower crop and worse taste of fruits. In this article, we will look at what fertilizer is ideal for strawberries and how to timed the fertilization correctly.

What fertilizer for strawberries to choose?
When selecting fertilizers for strawberries, it is important to know that strawberries need a balanced ratio of three main nutrients, namely nitrogen, phosphorus and potassium. Nitrogen promotes the growth of leaves and stems, but its excess can cause soft fruits prone to diseases. The phosphorus is crucial for roots and flowers, which directly affects the number and quality of the fruit. Potassium then improves the resistance of plants to disease and promotes the formation of sugars, thus affecting the taste and color of strawberries.
Another important aspect is micronutrients such as manganese, copper or zinc, which help improve photosynthesis, nutrient absorption and activate enzymes in plants. The best fertilizers for strawberries contain not only the right NPK ratio (nitrogen, phosphorus and potassium), but also these trace elements in a well absorbable form. For example, a fertilizer with a ratio of 8-12-32, which balances the needs of the strawberry throughout the season, is the ideal choice for gardeners. This composition promotes strong roots growth and rich flowering and subsequent fruits, with high potassium content to ensure healthy and tasty strawberries.
In addition to fertilizers from the store, strawberries can also fertilize with natural domestic means. The popular is, for example, compost that gives the soil organic matter and a wide range of nutrients. A good source of nutrients is also decomposed manure or urine, which contain nitrogen, phosphorus and potassium in natural form. Some gardeners also recommend watering from nettle leap, which contains beneficial micronutrients and promotes the immunity of plants. Domestic fertilizers are not only environmentally friendly, but also help improve the soil structure and promote healthy growth of strawberries.
When and how to fertilize strawberries?
Fertilization should be divided into several phases. The first dose of fertilizer is applied to planting, where we support the rooting of plants. Further fertilization takes place during vegetative growth, when plants need more nitrogen for healthy leaves and stems. In flowering and the formation of fruits, it is important to supply more phosphorus and potassium so that the plants have energy to develop quality fruits.
It is also important to fertilize strawberries after harvest, helping the plants to recover and prepare for the next season. If you grow strawberries in containers or elevated beds, it is advisable to use water soluble fertilizers that can be easily applied directly to the roots. Also, remember regular land testing so that you can adjust the fertilizer plan exactly to the current needs of your strawberries. Proper care will ensure strong plants and a rich harvest of tasty fruits.
