Pay attention to fertilization in the basin and spraying fertilizer on the leaves to cultivate strong mother branches. The main measures to protect fruits are: first, strengthen the supply of fertilizer and water and accumulate nutrients; The second is artificial pollination; The third is to sparse flowers and fruits. Lemon fruit is very big and needs a lot of nutrition. The normal leaf-fruit ratio is 30 to 40: 1.

You can also leave no weak branches and only 1 fruit for strong branches.
