What is the reason for the yellowing of frangipani leaves?

Reason 1 for the yellowing of frangipani leaves: soil pollution

Many flower lovers plant their flowers in soil that they prepare themselves, digging up soil from the streets and alleys. However, the soil that you think is fertile may not be safe. Some soils may contain chemical elements due to water, air or other reasons, which may affect the growth of flowers.

No matter where the soil comes from, be sure to sterilize it before using it.

The second reason why the leaves of plumeria turn yellow: incorrect watering

The watering mentioned here includes watering time, watering frequency, and watering amount. Watering on rainy days, or watering too frequently, will cause water to accumulate in the flowerpot, resulting in poor breathing and rot of the roots, causing the leaves to turn yellow. There is another situation: you water too little at ordinary times, water only when you remember, water too much at one time, and forget to water the soil in the pot and it becomes very dry. This watering method will also cause the leaves to turn yellow.

Normally, water the plants when the soil is dry and water them when the soil is wet, and understand the development laws of the plants according to their growth conditions.

The third reason why plumeria leaves turn yellow: improper light

Plumeria likes sunlight. In an environment with plenty of sunlight, it grows healthily and has a strong fragrance. If it grows in a shady environment for a long time, the plant will gradually turn yellow due to lack of nutrients and lack of chlorophyll in the leaves.

Place the plant in the sun for maintenance. Although frangipani is a deciduous plant, increasing the light exposure after bringing it indoors in winter can delay the fall of its leaves.

Reason 4 for the yellowing of plumeria leaves: pests and diseases

Yellowing and wilting of leaves are only the early symptoms of diseases and pests. If not prevented and controlled in time, the whole plant will die. Plumeria diseases and pests are unavoidable, but we can reduce them to a certain extent. Spray fungicides every month, strengthen ventilation and control humidity at ordinary times, and spray insecticides in time when pests and diseases are found.
