Dieffenbachia Care Guide

Welcome to our Dieffenbachia care guide! In this guide, we will provide you with  tips and guidance to ensure the health and longevity of your Dieffenbachia plants.

Dieffenbachia, also known as Dumb Cane, is a popular houseplant known for its beautiful foliage. With proper care, these plants can thrive and bring beauty to any indoor space.  Some of our Dieffenbachia are grown from Jordan's great grandmother's plant, that his father still has in his kitchen!  We're talking about a 100 year old, or more, plant!

Here are some important care tips to keep in mind:


Dieffenbachia plants thrive in bright, indirect light. Place your plant near a window where it can receive filtered sunlight. Avoid placing it in direct sunlight as it can scorch the leaves.


Dieffenbachia plants prefer temperatures between 65°F and 75°F (18°C to 24°C). Avoid exposing them to extreme temperature fluctuations or drafts.


Proper watering is crucial for the health of your Dieffenbachia. Water the plant when the top inch of soil feels dry to the touch. Ensure that the pot has drainage holes to prevent waterlogging, as this can lead to root rot.

It's important to note that Dieffenbachia plants are sensitive to overwatering. Avoid letting the plant sit in standing water, as this can cause the plant to rot.


Dieffenbachia plants thrive in high humidity. To increase humidity levels, you can place the plant on a tray filled with water and pebbles. As the water evaporates, it will create a humid microclimate around the plant.

Misting the leaves occasionally can also help increase humidity. However, avoid misting too frequently, as it can lead to fungal diseases.


Feed your Dieffenbachia plant with a balanced, water-soluble fertilizer during the growing season (spring and summer). Follow the instructions on the fertilizer packaging for the correct dosage.

It's important not to over-fertilize your plant, as this can cause fertilizer burn. Always dilute the fertilizer according to the instructions and avoid applying it to dry soil.


Regular pruning is essential to maintain the shape and size of your Dieffenbachia plant. Prune any yellow or damaged leaves, as well as any leggy or overgrown stems.

When pruning, make clean cuts just above a leaf node to encourage new growth. You can also propagate the cuttings to grow new plants.


Repot your Dieffenbachia plant every 1-2 years, or when it outgrows its current pot. Choose a pot that is slightly larger than the current one and use well-draining potting soil.

When repotting, gently loosen the roots and remove any dead or rotting roots. Place the plant in the new pot and fill it with fresh potting soil, ensuring that the plant is at the same depth as before.

Following these care tips will help ensure the health and beauty of your Dieffenbachia plants. Enjoy the lush foliage and vibrant colors that these plants bring to your indoor space!
