What fertilizer is good for peach trees?

Time for topdressing peach trees

1. Basal fertilizer for peach trees: Basal fertilizer can be applied to peach trees once in autumn, before or after the leaves fall and combined with autumn turning. You can dig a 40 cm deep trench under the tree and then apply the fertilizer.

2. Top dressing of peach trees: Peach trees can be fertilized 2-3 times a year, mainly with quick-acting nitrogen fertilizers, combined with a small amount of phosphorus and potassium fertilizers. If it is a high-yield garden, it can be applied 1-2 more times.

What fertilizer to use for peach trees?

1. On the basis of applying base fertilizer, use 1/2 of the total nitrogen fertilizer as topdressing, apply it once before the peach tree blooms and after harvesting the fruits, and the amount of topdressing each time accounts for one quarter of the total nitrogen fertilizer. Ternary compound fertilizer can also be applied once before flowering and after physiological fruit drop, and the amount of fertilizer applied each time is one third of the total amount.

2. Peach trees are sensitive to trace elements and require foliar fertilization. Spraying boric acid solution during the initial flowering period can increase the fruit setting rate. From late August to early September, spraying potassium dihydrogen phosphate solution once can enhance cold resistance. Spraying calcium nitrate solution during the rapid expansion period of the fruit can increase the hardness of the fruit.

Should I use urea or compound fertilizer for peach tree topdressing?

Organic fertilizer and urea can be applied to peach trees at the same time and can be mixed, but they must be used immediately after mixing, otherwise the fertilizer will easily become damp, especially after organic fertilizer and urea are mixed, which will cause dampness and lumps to appear in about 10 minutes.

Topdressing method for peach trees

1. Top dressing before budding: Top dressing can be done before the temperature rises after the peach tree is covered with a greenhouse. The main purpose is to supplement nutrients to enable it to sprout and bloom better. This has a good promoting effect on the continued differentiation of flower buds and increasing the fruit setting rate. Generally, nitrogen fertilizer is used as the main fertilizer, with an appropriate amount of phosphorus fertilizer.

2. Top dressing after flowering: Top dressing can be applied during the fruit setting period after the peach flowers have faded. At this time, the peach trees have consumed a lot of stored nutrients due to germination and flowering, and the young fruits and new shoots grow faster. The two are prone to conflicts in nutrient requirements. It is necessary to supplement with quick-acting nitrogen fertilizers, combined with phosphorus and potassium fertilizers, to promote the enlargement of young fruits and the growth of new shoots.

3. Top dressing before fruit harvesting: Top dressing can be done one month before peach fruit harvesting, mainly with phosphorus and potassium fertilizers. The main purpose is to promote rapid growth of fruit cells and increase cell gaps, thereby increasing fruit size, increasing yield, and improving quality.

4. Topdressing after fruit harvest: After peach trees are harvested, topdressing can be carried out to promote the growth of roots and new shoots, restore tree vigor, make branches and buds full and plump, increase the storage of nutrients in the tree, and lay a good material foundation for a high yield in the following year. It is better to use nitrogen, phosphorus and potassium compound fertilizers.
