Winterizing Mandevillas as a Houseplant
Mandevillas will not tolerate freezing cold weather so it’s best to overwinter them indoors until the warmer months arrive, before the temperatures drop below 60 degrees F.(15 C.). Make sure that your Mandevillas well watered also.
You may want to groom your plant a bit by trimming if it’s overgrown to control the upward and outward growth, inspect the plant for insects, and treat it with insecticidal soap, horticultural oil, or neem oil. Common insect pests of Mandevillas are aphids, scales, whiteflies, and red spider mites, allow the pesticide to dry from the plant’s leaves before bringing indoors.
Once your container-grown mandevilla is brought indoors locate an area that gets the most sunlight light, a South or West facing window is the best location, although plants use less (water) moisture during the winter months it’s important to ensure that your Mandevilla has sufficient water or the leaves will turn yellow followed by browning of the leaves and then leave drop.
The soil should be somewhat moist or damp to the touch, use your finger and check the top few inches of soil, 1-3 inches. A soil probe or soil moisture is the ideal tool that will give accurate readings.
Because of the winter months, there is no need for fertilizer applications, because during this time of the year is a plant’s dormant period or when a plant slows down from growing. This time is for your plant to rest, don’t try to force your Mandevilla to put out new growth or even to flowers, remember this is the time of the year for your Mandevilla to take a break. The ideal time to make a fertilizer application is during the spring months when the days are long.
How to Return Your Potted Mandevilla Outdoors After Overwintering
Once the warmer months return it’s time to return your potted mandevilla outdoors but before returning your mandevilla outdoors look for signs of early spring growth which is a clear indication that your Mandevilla is breaking dormancy. However, don’t move your Mandevilla outdoors until temperatures are consistently above 60 degrees F. (15 C.)
During the spring and summer months fertilize your Mandevilla every 2 weeks with triple 20 (20-20-20) or triple 10 (10-10-10), before applying fertilizers read and follow the manufacturer’s directions for the best result.
