Difficulty: Moderately Easy
Step1
Give dieffenbachia plants consistent light levels throughout the year. Dieffenbachias prefer the bright light with any direct sunlight filtered by a transparent curtain in the spring, summer and fall. In the winter, when there is less light available, remove the curtain to allow in the direct sunlight. This will give the plants nearly balanced light at all times.
Step2
Give dieffenbachias a warm temperature, ranging between 60 and 70 degrees Fahrenheit.
Step3
Provide increased humidity around a dieffenbachia. Humidity keeps the plant healthy and can be increased by placing trays of pebbles underneath the plant. Occasional misting with soft water and grouping with other plants also raises the humidity level for this plant.
Step4
Water dieffenbachias when the potting mix has partially dried. Water when you cannot feel moisture by sticking your finger into the soil.
Step5
Cut dieffenbachia stems back to about 6 inches tall if you do not like the look of the plant after it drops its lower leaves. The plant will regenerate spikes of growth from the bottom. Resume normal care from this point.
