As one of those common climbing plants, the Mandevilla will climb vertically up to 20 feet tall in ideal climates. The vines need a support structure, such as a trellis, to twist around while they grow. These vines are fast-growing, growing up to 10 feet in the first season.

Do mandevillas need big pots?

Plant one plant per 12 to 14 inch container to work best. Keep plants well watered and fertilized to stimulate vining growth and flowering. Mandevilla will grow fast during hot weather so don’t let the pots dry out.

How long do mandevillas last?

Mandevillas thrive in warm, humid weather and bloom continuously from late spring until frost. They are best purchased as potted plants. Wait until temperatures are reliably in the 60 degree F daytime temperature range (50 degrees F at night) before you plant them outdoors.
