Causes and treatments for yellow leaves on cactus

1. Waterlogging of the soil

1. Reason: Cactus is drought-resistant but not moisture-resistant and is afraid of waterlogging. If you water too much or fail to drain the water in time after rain, water will accumulate in the soil, causing damage to the root system and yellow leaves.

2. Treatment method: Stop watering immediately, remove the plant from the pot, cut off the rotten roots and yellow leaves, and then plant it in soil with good air permeability for maintenance.

2. Improper fertilization

1. Reason: Fertilizer needs to be applied regularly during the growth period of cactus to ensure normal growth of the plant. If no fertilizer is applied for a long time or too little fertilizer is applied, it will lack nutrients, grow poorly, and have yellow leaves.

2. Treatment method: Base fertilizer should be applied to the bottom of the pot, and fermented organic liquid fertilizer should be watered once every half a month to provide it with nutrients and help it recover.

3. Temperature discomfort

1. Reason: If the temperature is too low, it will easily cause the cactus roots to rot, but if the temperature is too high, it will easily cause scale insect damage, which will cause yellow leaves on the plant.

2. Treatment method: The temperature around the plants should be regulated, keeping it above 20°C during the day and not lower than 10°C at night.
