| Can mandevillas be planted outside all year round? |
| Mandevilla dipladenia is definitely a tropical plant and won't survive your winter weather outdoors, but makes a lovely greenhouse or houseplant. Mandevilla can grow to ten feet, so you need lots of room indoors. Don't cut your plant back, but gradually acclimate to indoor growing by taking it indoors at night and back outside during the day for about a week. It should be happy with temperatures between 65F - 70F indoors, bright light but not direct sunlight, ample water spring and summer, little water in the winter, lots of humidity - so mist the leaves every few days - especially when flower buds form. |
