When should the fruit-sizing fertilizer be applied to pear trees, and which water-soluble fertilizer works best?

Pear trees are a fruit tree that likes fertilizer and has a relatively high fertilizer requirement. Applying fruit-sizing fertilizer in time is very important in pear cultivation, as it directly affects the yield of pear trees that year and the income of pear growers. So when exactly should the fruit-sizing fertilizer for pear trees be applied? And which water-soluble fertilizer works better?

Timing of fruit-sizing fertilizer application for pear trees:

Every year from June to August is the period of rapid pear fruit expansion. At this time, fruit-swelling fertilizer should be applied in time. The fertilizer should mainly be high potassium, medium nitrogen or low nitrogen, and medium phosphorus or low phosphorus, which can improve the quality and yield of pears and promote flower bud differentiation in the later stage.

Application methods of fruit-sizing fertilizer for pear trees:

1. Underground topdressing:You can apply high-potassium water-soluble fertilizer 15-15-30+TE. For pear trees with severe potassium deficiency (mainly shown as shortened internodes, small leaves that are yellow-green, and leaf margins that curl and scorch; in severe cases, the entire tree's leaves show this condition), you can flush-apply ultra-potassium water-soluble fertilizer 13-6-40+TE.

2. Foliar spraying:After physiological fruit drop and up to the harvest period, spray 0.3%-0.5% monopotassium phosphate 2-3 times, which can allow the fruit to receive nutrient supplementation in time, with faster and better results.
