Symptoms and Control Methods of Physiological Diseases in Money Tree

Diseases caused by improper management in money tree are called physiological diseases, mainly including cold injury and weak, spindly growth.

Cold injury

The minimum overwintering temperature for money tree is 8°C; below 8°C, cold injury easily occurs. After being frozen, money tree tends to drop leaves, and in severe cases the whole plant dies.

Branches grow weak and spindly, with elongated internodes

This is mainly caused by insufficient light or too small spacing between plants and rows. Money tree has a relatively wide adaptability to light, but it should not live long-term in an environment with too weak light. For plants showing the above symptoms, shorten the branches that detract from their appearance, move the plants to a position with more ample scattered light, and maintain a relatively suitable density. It should be noted that plants that have grown "leggy" should not be moved directly into direct sunlight, to avoid sunburn.

Symptoms and Control Methods of Root Rot and Leaf Spot in Money Tree

Symptoms and Control Methods of Root Rot and Leaf Spot in Money Tree

Cause: a physiological disease, caused by improper fertilizer and water management.
Symptoms: the disease causes many large spots, affecting ornamental value and growth.
Many leaves develop paper-thin spots, irregular in shape, with the boundary between diseased and healthy tissue not very distinct. The leaf color is somewhat chlorotic and lacks luster. When the root system is pulled out, it is wet-rotten and brown.

Disease characteristics:Money tree has an underdeveloped root system; trees whose roots have not developed well often show symptoms of water deficiency, while excessive watering during care, combined with continuous rainy days or low temperatures (below 16°C), often causes root rot.
Control methods:This disease is controlled through cultivation techniques. When purchasing, choose trees with healthy root development; manage fertilizer and water according to weather and temperature, watering more when hot and less when cold. A substrate moisture content of about 60% is the standard for water control (that is, the substrate forms a ball when squeezed by hand and breaks apart when released). During the peak growing season, apply fertilizer about once every half month, with an appropriate increase in phosphorus and potassium fertilizer; when roots first begin to rot, spray foliar fertilizer to maintain the roots; in winter, light must be sufficient.

Control of Root Rot and Leaf Spot in Money Tree (Malabar Chestnut)

This disease is a physiological disease caused by improper fertilizer and water management. The root system of money tree is notwell developed, and trees whose roots have not developed well often show symptoms of water deficiency, while excessive watering during care, combined with continuous rainy days or low temperatures (below 16°C), often causes root rot.

The disease causes many large spots, affecting ornamental value and growth. Many leaves develop paper-thin spots, irregular in shape, with the boundary between diseased and healthy tissue not very distinct. The leaf color is somewhat chlorotic and lacks luster. When the root system is pulled out, it is wet-rotten and brown.

Control methods: no good control method has yet been found for this disease; it is recommended to strengthen thepreventionwork for this disease.
