Raven ZZ Plant Care Guidelines

Light Requirements

Raven ZZ plants are adaptable to various lighting conditions, ranging from bright indirect light to low light. However, to achieve optimal growth and maintain the plant’s dark foliage, providing ample bright, indirect light is recommended. Avoid exposing the plant to direct sunlight, especially harsh afternoon sun, as it can cause leaf burn.

Soil Selection

Choosing the right soil mix is crucial for the healthy growth of raven ZZ plants. While they can tolerate standard houseplant soil, it is best to opt for a well-draining mix enriched with perlite, pumice, or sand. These additives promote excellent drainage and prevent the risk of overwatering, which can lead to root rot.

Watering Practices

Raven ZZ plants possess rhizomes that store water, allowing them to withstand drought conditions. Thus, they do not require frequent watering. Overwatering can lead to root rot and eventually kill the plant. To prevent this, ensure the soil dries out completely between waterings. During the active growing season (spring and summer), increase the frequency of watering, but always allow the soil to dry out before the next watering. Remember, it’s better to underwater than overwater these succulents.

Temperature and Humidity

As tropical plants, raven ZZ plants thrive in warm temperatures and average humidity levels. They can tolerate humid conditions but do not necessarily require them. Maintain temperatures between 65 to 85 degrees Fahrenheit (18 to 29 degrees Celsius) to avoid shocking the plant.


During the active growth period, raven ZZ plants benefit from regular fertilization. Applying a balanced houseplant fertilizer every three to four weeks will encourage strong and healthy growth. Choose a fertilizer specifically designed for houseplants and follow the instructions on the packaging.

Potting and Repotting

Raven ZZ plants have a slow growth rate and only require repotting when they outgrow their current container. These plants can tolerate being rootbound, so repotting is typically necessary every two to three years. Signs that indicate the need for repotting include roots protruding from the drainage holes or rhizomes pushing against the pot’s edges. When repotting, choose a slightly larger pot to avoid overwatering and refresh the soil to provide essential nutrients.

Dealing with Pests and Diseases

Like other houseplants, raven ZZ plants may encounter common pests such as mealybugs, scale, spider mites, and thrips.
