How to care for your Mandevilla
Use these instructions to care for a Mandevilla. This guide will tell you how to water a Mandevilla; its light, temperature, humidity preferences and any additional care it might need to help it grow.
Mandevilla
Place your Mandevilla plant in full sunlight for at least 6 hours a day. In dimmer light, your plant might not bloom as much, but as an indoor plant, it might tolerant bright, indirect light. You can also supplement with a grow light.
When the top inch of your Mandevilla dries out, your plant needs watering. Your plant appreciates regular watering as long as it has the proper drainage. Although the Mandevilla is fairly drought tolerant, remember not to let the soil dry out completely.
Moisture in the air makes your Mandevilla happy. So misting the leaves or placing a humidifier close by will help your plant to thrive. Another idea is to keep a wet pebble tray next to your plant.
Mandevillas also love warmth, and 70℉ to 90℉ makes your plant feel the most comfortable. Your plant might tolerate cool temperatures s long as they stay above 60℉. Also, remember to keep your Mandevilla plant away from drafts and vents.
Spring and summer are the best times to fertilize your Mandevilla plant, specifically every two weeks. You can use a balanced formula diluted in water at half strength. During the fall and winter, you can stop fertilizing your plant as it goes into dormancy.
The Mandevilla is considered toxic to pets and humans if ingested. Plus, the milky sap that drips out of cut stems can irritate your skin.
Mandevillas cannot survive the winter throughout most of the US, but it’s easy to overwinter your plant indoors. To do this, wait until night temperatures dip below 50°F. Cut back the vining stems as much as you’d like, leaving at least 8” of stem length. Keep the plant in a bright spot indoors, water sparingly, and do not fertilize. Your Mandevilla will not grow quickly, if at all, over the winter. Begin fertilizing it again in the early spring and move it outdoors once temperatures stay above 50°F.
