What is the best fertilizer for bayberry trees? How to fertilize?

The bayberry tree is known as the " fertilizer wood". It is not demanding in terms of fertilizer and water, and can grow in barren mountains and barren land. But it does not mean that it does not need fertilization. Good fertilization is a necessary measure to achieve high quality and high yield of bayberry trees. So what is the best fertilizer for bayberry trees? How to fertilize? Let’s learn more about it below.

What is the best fertilizer for bayberry trees?

According to the fertilizer requirements of bayberry trees, quick-acting fertilizers are mainly used, and nitrogen, phosphorus and potassium fertilizers need to be applied in appropriate amounts. Among them, bayberry is a potassium-loving fruit tree and has a large demand for potassium. The best ratio of nitrogen, phosphorus and potassium is 1:0.5:4. Potassium fertilizer can accelerate the rate of lignification and increase the sugar content of the fruit. Fertilizers like potassium sulfate and potassium sulfate compound fertilizers are very suitable for the growth of bayberry trees, and can effectively promote flower bud differentiation and spring shoot growth.

How to fertilize bayberry trees?

1. Fertilization period

(1) Basal fertilizer: Basal fertilizer is applied in autumn, around October every year, mainly composed of decomposed manure, compost and cake fertilizer.

(2) Shoot-promoting fertilizer: also known as germination fertilizer or spring fertilizer, it is applied before the bayberry trees sprout from mid-to-late January to February each year, accounting for 20% of the total fertilizer. Apply 300-500 grams of urea or 20-30 kilograms of diluted human feces and urine and 1 kilogram of potassium phosphate per plant.

(3) Fruit-strengthening fertilizer: Apply before summer shoots emerge in May each year, mainly quick-acting nitrogen and potassium fertilizers.

(4) Post-harvest fertilizer: In early to mid-July after the fruit is harvested in a good year, apply quick-acting fertilizer mainly composed of potassium fertilizer and supplemented with nitrogen fertilizer to help restore the tree vigor and start flower bud differentiation in time. For trees that bear fruit in a bad year, apply a special compound fertilizer for fruit trees after harvest to help reduce flower bud differentiation in autumn and winter.

(5) Winter fertilizer: In October and November, it is necessary to apply basal fertilizer in combination with deep plowing and hole enlargement. Apply 25-30 kg of manure or 3-5 kg ​​of cake fertilizer per plant, or 40-45 kg of compost, 1.5-2 kg of compound fertilizer, and 2-2.5 kg of wood ash.

2. Fertilization method

For young trees, the method of expanding the holes and deepening the fertilizer application year by year is adopted. For mature trees, apply fertilizer by surface broadcasting and strip application, then cover with soil. Avoid digging large holes or ring-shaped trenches for fertilization.

The above is an introduction to the types, time and methods of fertilizer application for bayberry trees. Note that during the fertilization process, the amount, time and method of fertilization should be appropriate to meet the growth needs of the bayberry tree, while also effectively avoiding the negative effects of improper fertilization.
