Mandevilla is a reliable flowering vine with big, leathery leaves and stunning trumpet shaped blooms. However, the vine is frost sensitive and suitable for growing outdoors only in the warm climates of USDA plant hardiness zones 9 through 11. In cooler climates it is grown as an indoor plant.

Like all potted plants, occasional repotting is necessary to keep the plant healthy and to provide ample growing space for the roots. Fortunately, repotting mandevilla isn’t difficult. Read on to learn how to repot mandevilla in a new pot.

When to Repot a Mandevilla

Mandevilla should be repotted every year or two, preferably in early spring. However, if you didn’t get around to pruning your mandevilla vine last year, it’s best to wait until fall, then prune and repot at the same time.

How to Repot Mandevilla

When repotting a mandevilla, prepare a pot no more than one size larger than the current pot. Ideally, the container should be slightly wider but not too deep. Be sure the pot has a drainage hole in the bottom, as mandevilla is susceptible to root rot in soggy, poorly drained conditions.

Fill the pot about one-third full of a lightweight, fast-draining potting mix such as a blend of commercial potting soil, sand, and compost. Remove the plant carefully from its pot. Trim any roots that appear dead or damaged.

Place the plant in the center of the pot. Adjust the soil in the bottom of the pot, if necessary, to ensure the mandevilla is planted at the same soil level as in its current pot. Planting too deeply can damage when moving to a new pot.

Fill in around the roots with potting mix. Firm the mix with your fingers, but don’t compact it. Water the mandevilla plant well and then install a trellis to support the vine. Put the plant in light shade for a few days while it acclimates to its new pot then move the mandevilla into bright sunlight.
