How to Grow Dieffenbachia (Dumb Cane)? Master These Cultivation Methods

Temperature: Keep the room temperature between 10°C and 18°C, water according to temperature changes, and master the amount of watering. Fertilizing: In the early growth stage, it has a high demand for nutrients, so apply phosphate fertilizer once every half month. Light: About 6 hours of light per day, do not expose it to the scorching sun.

Cultivation Methods for Dieffenbachia

1. Temperature

Control the indoor temperature. Dieffenbachia is a cold-resistant plant, but when the temperature drops below 0°C, its growth becomes very slow and the leaves may even wither, so an indoor temperature of 10°C to 18°C is most favorable for the growth of Dieffenbachia.

2. Watering

Water daily to keep the soil moist. You can wait until the soil dries out before watering again, which prevents water accumulation in the pot and root rot. In summer, when the temperature is too high and water is easily lost, increase the frequency of watering.

3. Fertilizing

During the growth stage, the plant needs a large amount of nutrients, so apply liquid fertilizer about once every 15 days. No fertilizing is needed at the seedling stage. During the flowering period, apply some phosphorus-containing liquid fertilizer, which can promote more blooms and also prolong the flowering period.

4. Light

The growth of Dieffenbachia cannot do without light. Too much or too little light will cause the leaves to turn yellow and wither, so light is very important. It needs 6 hours of light per day, and the best placement is in a spot with diffused light.

5. Pests and Diseases

The high temperatures of summer lead to an increase in the number of scale insects and red spider mites, so pay constant attention to whether pests and diseases are present in daily care. Once they appear, we must promptly treat them with medication, so as to ensure that Dieffenbachia can grow healthily.
