As an experienced strawberry grower, I am glad to answer your question here. Let me tell you the most interesting thing about these plants is that they give you several hints when they require fertilizers.
If your plants have begun to give clues such as pale leaves or immature fruits, you can maintain them using natural compost. Why you should prefer compost to commercial fertilizers is because they are organic and contain decomposed leaves and plant materials that are good for plant growth. Also, if leaves still remain yellowish, consider using a quality
nutrient additive such as golden Tree. You’ll notice the difference after just a few days of use.
