The Main Factors To Consider When Shopping For the Best Fertilizer for Strawberries

Applying a top quality fertilizer for strawberries the right way will nourish them with essential micronutrients that’ll promote healthier growth and increased yields. However, these fertilizers aren’t made equal. There’re certain considerations you need to make before making your choice. Here’re the most important factors to consider when shopping for fertilizer for strawberry plants.

1. Fertilizer analysis

Fertilizer analysis is a description of the nutrients contained in a fertilizer. It’s represented in the form of NPK ratio. Essentially, strawberry plants require the three basic micronutrients to grow healthier and produce a higher yield. These nutrients include nitrogen, phosphorous, and potassium. Ensure the fertilizer you choose has all these three micronutrients in the fertilize analysis/NPK ratio. Any extra micronutrients and minerals in the fertilizer are an added advantage.

2. Type of fertilizer

You’ll have the chance to choose between organic and chemical fertilizers. Organic fertilizers for strawberries are sourced from natural ingredients and often come in the form of granules. They’re typically applied directly to the soil, followed by watering to activate them. The main advantage of organic fertilizers is that they’re friendlier to the environment than chemical fertilizers.

On the other hand, chemical fertilizers come in the form of a powder or liquid concentrate. Chemical fertilizers require premixing with water before application. Their main advantage is that they show results faster. However, they may have negative effects on the environment.

3. Frequency of application

Some fertilizers are applied after a few days or weeks while others are applied once or a few times in a growing season. A fertilizer that requires more frequent application will be more tedious to work with but maybe less toxic and less likely to burn strawberry plants. On the other hand, a fertilizer that’s applied only a few times in a growing season will be effortless to work with but might be more toxic and more likely to burn strawberry plants if applied excessively.

4. Ease of application

Ensure the fertilizer you’re choosing is easy to apply. If it requires mixing with water before application, then it should be water-soluble for even application. If the fertilizer comes in the form of granules, the packaging should be able to dispense the granules in a controlled manner to avoid overfeeding one area.


Strawberries are rich in fiber, antioxidants, manganese, and vitamin C among other nutrients. By fertilizing your strawberry plants, you’ll enjoy a bigger yield with sweet, juicy berries. However, this will only be possible by applying the best fertilizer for strawberries the right way and at the right time.
