Pineapple flowers like the warm and humid climate. The basic leaves of pineapple are closely arranged and show a lotus-shaped tube shape, and the center of the tube is cup-shaped to store water without leakage, so in the process of culture, we should often irrigate to keep the center and leaves moist to ensure the water supply of the whole plant. In order to make the pineapple blossom grow luxuriantly, it is necessary to apply a small amount of foliar fertilizer to the leaf tube every two weeks, such as spraying Shibao, according to the instructions on the use of foliar fertilizer and the growth of the flower.

Perhaps many friends have had such an experience. When the pineapple is bought, it may look very good-looking and brightly colored, but after a period of time, the leaves of the pineapple may wither and turn yellow. so what is the cause of the yellowing of the leaves?

Fertilizer application

The reason: the concentration of fertilizer applied to the pineapple flower is too high, which makes the inorganic salt ions accumulate in the leaves, and the protoplast dehydration occurs in the mesophyll cells with different ion concentrations, which leads to the yellowing of the pineapple leaves.

Solution: in the process of fertilization, try to dilute the high concentration of fertilizer solution to a lower concentration in the fertilization process.

Diseases and insect pests

Cause: caused by fungal or bacterial infections or epiphytic pests, the main symptoms are spots or decay.
