About Dipladenia
Mandevilla sanderi is a moderate-growing climber in the Apocynaceae family. It reaches around 3 m tall and 1.5 m wide at maturity, with evergreen foliage. Red, pink and white flowers appear for much of the year.
Where to grow Dipladenia
Dipladenia suits tropical, subtropical and warm-temperate climates and grows best in full sun and part shade or morning sun. It is frost tender, so protect it from hard frosts or grow it in a sheltered spot or pot.
Soil & planting
Dipladenia does best in loamy and free-draining soil. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Dipladenia is regular, moderate watering. A feed in spring with a balanced fertiliser keeps growth strong. In its first year, water deeply once or twice a week to settle the roots in, then taper off as it establishes.
Pruning & care
Prune Dipladenia after flowering to keep it compact and encourage the next flush of blooms. Overall it is moderate maintenance.
Using Dipladenia in the garden
Dipladenia earns its place for pots and courtyard containers, a feature or specimen planting and hanging baskets. It is equally at home in the ground or a large pot on a balcony or courtyard.
Companion planting & design
For a cohesive, low-care bed, pair Dipladenia with other plants that enjoy the same regular, moderate watering and tropical climate. Group three or five together for impact rather than dotting single plants through the garden.
Good to know
Note that it is toxic to cats and dogs, so site it away from pets that chew. It is thornless and easy to handle.
