Soil: Fast draining soil is key. Can tolerate different soil types.

Temperature: Prefers warm weather. Can withstand temperatures down to 32 degrees for a brief period of time.

Water: Requires moderate water. Drought tolerant once mature. We recommend occasional, deep waterings. Allow the soil to be dry between waterings. Either use a moisture meter or stick your finger through the soil to gauge the moisture level.

Sun: Full sun. In partial shade, the plant will grow fewer flowers.

Pests: Cascabela theviatas have minimal pests, which are usually aphids and spider mites.

For aphids, blast them off with water if the infestation is light. Otherwise, use horticultural oil or soapy water.

For spider mites, control the infestation as soon as it’s discovered. Some options are horticultural oil applied several days apart as well as insecticidal soap combined with hydrogen peroxide. Use commercial pesticide for severe infestations.

Whenever using any kind of pesticide, be aware that it can damage the plant if the temperatures are in the 80s or above.
