What fertilizer to use for lemon trees

Lemon likes warmth and is not cold-resistant. It is suitable for cultivation in subtropical areas with warm winters and cool summers. The suitable annual average temperature is between 17-19℃. It is suitable for planting in warm, deep soil, well-drained and gently sloping land.

Lemon trees are suitable for applying farmyard manure. Organic fertilizer and fermented farmyard manure are high-quality base fertilizers for lemon trees. These fertilizers have a long fertilizer effect and more comprehensive nutrients. They can improve the physical and chemical properties of the soil in the fruit garden to a certain extent and provide high-quality environmental conditions for the growth of fruit.

After the beginning of spring, lemon trees should be fertilized with bud fertilizer, and organic fertilizer should be applied in combination with inorganic fertilizer. After fertilization, the ditches should be cleared and the soil should be covered. Fertilizers such as manure, urea, calcium sulfate, potassium sulfate, zinc sulfate 3, boric fertilizer, and ferrous sulfate can be used.

How to fertilize a lemon tree

When applying fertilizer, dig trenches on both sides of the lemon tree, away from the base, and expand outward from the trenches dug last year. Apply the prepared organic fertilizer and then fill it in. After a few years, the entire orchard can be dug and fertilized.

Spring fertilization

Lemon trees need to be fertilized around April in spring, mainly nitrogen. The largest amount is used from the flowering period to the young fruit swelling period, and gradually decreases from the fruit coloring period.

Summer fertilization

Lemon trees are fertilized in summer from June to July, mainly phosphorus fertilizer, which reaches its peak during the vigorous growth period of new shoots and the fruit expansion period. The absorption of phosphorus increases again after the fruit is harvested.

Fall Fertilization

It is best to apply fertilizer in mid-October in autumn. Fruits need a certain amount of potassium. The absorption of potassium is relatively stable throughout the annual growth cycle, but the absorption of potassium also increases significantly during the fruit expansion period.

Winter fertilization

It is appropriate to apply fertilizer in winter from November to December. Topdressing should mainly be done with decomposed human feces or urine or urea, wood ash and other quick-acting fertilizers. The amount of fertilizer applied this time must be less to avoid fertilizer damage.

Key points for fertilizing lemon trees

1. When digging trenches and applying fertilizer to lemon trees, be careful not to dig trenches in the same place every time you apply base fertilizer, as this will damage the new roots that grew last year.

2. When lemon trees are fertilized with concentrated fertilizers or raw fertilizers, the roots may be burned and the plants may die. Therefore, it is necessary to remove the plants from the pots in time and replant them.

3. Lemon is light-loving and has high requirements for light. When there is insufficient light, many flowers and fruits will fall and the yield will be low. Therefore, after fertilizing, it must also be given sufficient light.
