What fertilizer is best to apply before and after harvesting persimmon trees?
What fertilizer is best to apply before and after harvesting persimmon trees? Why apply fertilizer even after harvesting? Before and after fruit harvest, persimmon trees should be given nitrogen and potassium fertilizer to promptly replenish the tree's nutrients and raise its nutrient level, which helps the tree flower and fruit normally the following year. The specific method is: apply pre-harvest fertilizer 15~20 days before harvesting the persimmons, mainly with quick-acting, fast-dissolving nitrogen and potassium fertilizer. For trees bearing 50 kg or more, apply 2~3 kg of urea and 0.5~1 kg of potassium chloride or potassium sulfate per tree, or 1~1.5 kg of potassium sulfate, broadcast after rain or dissolved in 50~60 times clear water and drenched on. Apply post-harvest fertilizer within 10~15 days after harvesting, mainly with complete nitrogen, phosphorus and potassium fertilizer and high-quality organic fertilizer. Along with clearing the orchard, remove all kinds of weeds around the persimmon tree, then dig a ring-shaped trench 25~30 cm deep and 25~30 cm wide around the tree's drip line, thoroughly stir and mix 2~3 kg of nitrogen, phosphorus and potassium compound fertilizer with 40~50 kg of composted, fully rotted human, livestock and poultry manure, apply it into the ring trench, and cover with soil.
