How to take care of Dieffenbachia?

Here is how you can take care of Dieffenbachia:


Everyone knows how important light is for a plant’s growth.

Most varieties of Dieffenbachia do well in low lights, but some of the varieties need a little more indirect sunlight to grow. The plant will grow in low light as well, but the growth will be slow.

To facilitate healthy new leaves, you should provide them more indirect light to the plant but bear in mind that direct sunlight can scorch the leaves.


The plants need water but overwatering the indoor plants can destroy them. Dieffenbachia plants like to neither sit in the water nor dry out completely. You need to figure out when the plant needs water. Make sure the soil does not dry out completely, as it may ruin the plant. Also, ensure that the plant never sits in the water.


The plant loves moisture in the air. You should have 60 percent humidity level in the air. You can also use a humidifier to maintain the humidity level. Place the plant atop the tray filled with pebbles and water if you do not have a humidifier.


It is highly important to know the right temperature Dieffenbachia plants need to grow. The plant needs a temperature between 60-850F. Bear in mind that if the temperature drops below 500F, Dieffenbachia will stop growing.


If you are planning to grow Dieffenbachia, you should know when the right time to feed the plant is. You should not feed them in winter. In case you have put the pot in a place where the plant is getting enough bright light, then you should feed it more frequently. Feed the plant half-strength complete liquid fertilizer during the growing season.
