The causes and treatments of yellow leaves of Areca palm

1. The temperature is too low

1. Reason: Areca palm likes a warm environment, is not cold-resistant, and is in a low temperature environment for a long time. The plant is susceptible to frost damage, which can cause the leaves to turn yellow.

2. Treatment method: It needs to be transferred to a warm environment and maintained for a period of time before it returns to normal. The minimum temperature in winter must not be lower than 10℃, so some insulation and anti-freeze measures need to be taken to help it survive the winter safely.

2. Improper watering

1. Reason: Areca palm likes a humid environment, but cannot withstand waterlogging. Excessive watering will damage its root system and directly cause the leaves to turn yellow. If you water it too little, it won't get enough water to grow, and its leaves will turn yellow and wither.

2. Treatment method: If it is caused by over-watering, you need to stop watering, turn over the soil, place it in a cool and well-ventilated place for a period of time, and then water it normally after it slowly returns to normal. If it is due to insufficient watering, it is necessary to immediately replenish it with sufficient water, but there must not be any stagnant water to avoid damaging its root system.

3. Too much light

1. Reason: Areca palm likes light, but is more suitable for growing in a semi-shady environment. If the leaves are exposed to strong light for a long time, they will be burned and turn yellow.

2. Treatment method: Immediately move it to a cool and well-ventilated place for maintenance, cut off the leaves that have turned yellow, give it the necessary water, and it will return to normal after a period of maintenance. In summer, it can be placed under a shade shed or tree for maintenance.

4. Unsuitable soil

1. Reason: Areca palm is suitable for planting in well-drained sandy and slightly acidic soil. If the soil is not acidic enough, it will affect the absorption function of its roots and cause the leaves to turn yellow.

2. Treatment method: Change the soil regularly. The new soil should be slightly acidic, not too alkaline. Before changing the soil each time, the new soil needs to be exposed to the sun for disinfection.
