Mandevilla

What is the plant

Mandevilla vine (rocktrumpet plant) has become a popular spring garden center item over the past few years. These vigorous plants make an excellent spring and summertime addition to any landscape, patio or trellis vines and overwinter indoors.

The Mandevilla plant got its name from Henry Joseph Mandeville a gardener and British diplomat in 19th-century Argentina. You’ll easily recognize this lovely tropical plant by its glossy oval leaves, colorful trumpet-shaped flowers, and enthusiastic vining habits. The Mandevilla vine is excellent for growing up arches, use as pergola plants and growing as a trellised potted flowering vine on a patio. The plant is easy to care.

How to Care for the Plant

Water
Provide a slow, steady trickle of water on a weekly basis. Soak the soil thoroughly, and be sure the plant has good drainage. These plants do not like to stand in water and will develop root rot if not properly drained. If you are keeping your plant indoors, spray the leaves daily to keep humidity levels adequate.
Fertilizer
For growing, flowering plants in the spring and summer use a well-balanced, water-soluble fertilizer that delivers a healthy dose of phosphorous (e.g. 10-20-10). This will help your plant maintain the energy it needs for vibrant growth. During times of heavy growth and flowering, you may need to apply a liquid fertilizer once every week or two. As the growing season winds down, you should stop fertilizing to help prepare your plant for the winter months.
Sunlight
Place your Mandevilla in an area where it can stay warm and get plenty of bright, indirect light.

Soil
A good compost-based potting mix or soil for container plants can make a good base, but you should mix it with some very fine gravel or sand for lightness and good aeration. A combination of builder’s sand, coco coir or peat moss and good quality potting mix in equal parts is ideal.
Temperature
The plant should stay above freezing (50F is best) throughout the winter.
Container
Any type of container with drainage holes. Pay attention to the size of the container. Plants should have enough room for the roots to spread a bit, but if given too much room, they will put all their energy into producing roots.
