Mandevilla – Sun Parasol® Giant Red Emperor
Resists: Deer, Rabbits
Adapatable as House Plant
Dead-Heading Not Necessary
Mandevilla needs plenty of sun and does best when it is hot. It will struggle if temperatures are lower than 45 degrees. It can be overwintered indoors with appropriate care. It will go out of flower in the winter and may drop leaves to help it survive the winter. Do not over water in the winter, which is problematic. Keeping the soil on the dry side can help mitigate root rot issues. Use good, well-drained potting soil with Mandevilla. Spider mites and mealy bugs can be problematic. Treat as needed. Your local garden center can help you choose an appropriate treatment method.
This tropical plant is a great option for containers with a trellis for it to climb.
