How to plant and grow mandevilla

Classic tropical vine, mandevilla (Mandeville) They are a great way to add a pop of color to any sunny vertical space in your garden. With large, showy flowers that last all summer long and the fact that the plant is low-maintenance it makes it a great choice for a vine. Mandevilla vines have seen a resurgence in popularity in recent years, and breeding work continues to expand vine varieties.

Mandevillas are all about large, tropical-looking flowers. They come in shades of pink, red, white, and many shades in between. Now there’s a new color added to the collection, which is beautiful apricot. The large, five-petaled flowers often have a rich golden throat inside that adds to the tropical look. The flowers are borne in clusters that continue to grow and add more buds all the time. Be careful not to damage these growth points in the flowering clusters, or new buds will not form on that stem. The size of the bloom can vary slightly depending on the variety. In general, small flowers tend to be more abundant, and large flowers are slightly sparser but very large.

Although mandevilla is not classified as toxic to animals by the ASPCA, it can be mildly toxic when ingested, so keep the plant away from curious children or pets. The milky sap that exudes when cut can also irritate the skin on contact.

Where to grow mandevilla?

While mandevilla is typically grown as an annual because it dies when exposed to near-freezing temperatures, it can overwinter indoors. It is perennial in frost-free zones in USDA hardiness zones 10-11. Mandevilla is an excellent choice for the garden or patio.

How and when to plant mandevilla

Plant mandevilla outdoors in mid- to late spring after the temperature consistently exceeds at least 50 degrees F. Vines benefit from a trellis or other support. If you plan to overwinter the plant indoors, plant it in a container with drainage holes and filled with all-purpose potting soil.

Mandevilla care tips

As far as caring for these plants is concerned, mandevilla plants are low maintenance.

a light

Mandevilla needs 6 to 8 hours of full sun for best flower production. In hotter areas, it benefits from some shade during the afternoon.

Soil and water

When planting outside, choose a location with good drainage and rich soil. Amend the planting area with compost or other organic matter to support flowering. Water regularly to keep the soil moist but not excessively wet.

Temperature and humidity

The preferred temperature range for mandevilla growing outdoors is 68-90 degrees Fahrenheit. Anything below 50 degrees Fahrenheit will likely damage the plant. If the plant overwinters indoors, keep the temperature in the range of 60-65°F at night and 70°F or warmer in the day.

Fertilizer

Like most hardy plants that flower for long periods, mandevilla benefits from a good dose of fertilizer every now and then.

pruning

If the plants become too wild for your liking, mandevilla can be pruned or trained to keep them within bounds. In addition, this will encourage further branching and flowering.

Potting and repotting

When potting your mandevilla, use a lightweight, well-draining potting mix. Trim off any dead or damaged roots, then place the plant at the same depth as in the previous container. Replant mandevilla every year or two in the spring into a pot just one size larger than the current one.

Pests and problems

Mandevilla does not have major pest problems, but it can attract mealybugs, aphids and scale insects. The plant is usually ignored by deer and rabbits.

How to propagate mandevilla

You can propagate mandevilla from cuttings or seeds. In spring, take 3-inch cuttings from the tip of the plant or side shoots and remove all but the top two leaves. Dip them in rooting hormone and plant them in a well-draining potting mix. When starting seeds, use fresh seeds. Wait for it to dry on the plant, then harvest the seeds, soak them in water overnight, and plant them in well-drained soil.

Mandevilla species

Initially, all mandevillas were climbers and vines, but now some have more of a shrub form.

New Mandevilla varieties

More recently, gardeners and plant breeders have been curbing and reducing the size of mandeville trees. Many of the newer varieties are great choices for hanging baskets and even for spilling out of a container. Branching is also improved, creating denser plants and greater flowering potential.

With all the effort to cut back the size of these plants, the foliage can be quite variable between cultivars. Older varieties tend to have much larger leaves that are rougher in texture and have more pronounced veins. The smaller, more bushy species tend to have smaller leaves that are generally smooth and somewhat shiny. Smaller leaves showcase the flowers more.

Frequently asked questions

  • When do mandevillas bloom?

    The flowering season typically extends from early summer until the first frost, as cold temperatures will kill the plant unless you bring it indoors.

  • Will Mandevilla return next year?

    If you live in USDA zone 8 or a warmer area, the roots will still survive after the plant dies back, and may grow back in the spring without any encouragement from you. If you live in a cooler area, bring the pot inside when the outside temperature begins to drop to the 40°F to 50°F range and then replant it outside in the spring once temperatures remain above the same range.

  • Can I grow mandevilla indoors all year round?

    You can grow this plant indoors all year round if you can provide a warm, sunny location such as a south-facing window. Water it when the soil feels dry to the touch, and fertilize it in the spring and summer. Repot them in a slightly larger pot in the spring and prune them by a third in the fall.
