What to do if Clivia leaves have spots

Causes of spots

Improper fertilization

Applying unfermented fertilizer will cause the bacteria to multiply in large numbers in the potting soil.

Improper soil replacement

If the potting soil is not changed for a long time, the nutrients in the potting soil will decrease and pathogenic bacteria will exist. If the plant has wounds, it is easy to be infected by bacteria.

Imbalance of nitrogen, phosphorus and potassium in fertilizer

This is especially caused by insufficient potassium fertilizer or direct contact of fertilizer with the roots during fertilization. Rust spots on individual leaves are often caused by fertilizer directly contacting a fleshy root or a wound.

Take precautions

First of all, we must prevent the plants from root rot so that the leaves can get enough nutrition. Secondly, we must prevent external injuries and prevent the spread of wounds. The amount of fertilizer applied must be controlled well, and excessive fertilizer should be avoided. In summer, do not water the pseudobulbs of mature flowers. In summer, we must pay attention to ventilation, cool down, strengthen management, and regularly spray carbendazim, thiophanate-methyl, methyl tolbutamide, agricultural streptomycin and other sterilization drugs for prevention and control, which can reduce and eliminate the occurrence of leaf spot and leaf yellowing.

Replace new soil

To prevent and control leaf spot disease, the soil can be changed. When changing the soil, wash the fleshy roots with clean water, dry them and then put them in the pot. If some leaves are already rotten and look terrible, just cut them off.

Spraying
