How to Fertilize Strawberries: A Detailed Guide to Fertilization Techniques for Growing Strawberries
1. Fertilizer Requirements Strawberry roots are relatively shallow, have a strong ability to absorb nutrients, and have a high nutrient demand. They are very sensitive to nutrients, and both excessive and insufficient fertilization can have adverse effects on growth and development, yield, and quality. Nitrogen fertilizer can promote the formation of a large number of leaves and runners, strengthen vegetative growth, increase fruit size, and raise yield; nitrogen deficiency causes leaves to turn yellow, with localized scorching, and they become slightly smaller than normal leaves. Phosphorus fertilizer can promote flower bud differentiation and increase the fruit-setting rate; phosphorus deficiency causes purplish-red spots to appear on the appearance of the upper leaves, and flowers and fruits tend to be smaller. Potassium fertilizer mainly promotes fruit ripening, increases the sugar content of the fruit, and improves fruit quality; potassium deficiency often causes black, brown, and withered areas at leaf margins, and in severe cases they become scorched, with older leaves suffering more seriously, while the fruit is pale in color and poor in taste. In addition, strawberries are very sensitive to chlorine, so the use of chlorine-containing fertilizers should be controlled.
