Mandevillas or Dipladenias (Mandevilla spp.) are very popular, easy-care flowering shrubs and climbers! They are loved for their long lasting flowers and flowering period with their red, pink, white and yellow flowers. Their easy-care nature and drought hardiness make them perfect for container gardens and pots.


How to grow Mandevilla in a garden

  1. Choose a position in full sun or part shade with well drained soil.
  2. Enrich the soil with Yates Thrive Natural Blood & Bone with Seaweed. If the soil is clay based, add gypsum and fork in well. 
  3. Dig the planting hole twice as wide and to the same depth as the root-ball. Remove the plant from the container and gently tease the roots.
  4. Position in hole and backfill, gently firming down. Form a raised doughnut shaped ring around the plant, creating a well so that water will go where it’s needed most. Water in well. 
  5. Mulch with an organic mulch like woodchip or pea straw, keeping it away from the base of the plant.
  6. Water deeply, once or twice a week, depending on weather conditions, allowing to dry out slightly in between waterings. 
  7. During the growing and flowering season feed with Yates Thrive Rose & Flower Granular Plant Food. TIP: for an added boost apply Yates Thrive Natural Fish & Seaweed+ Plant Food Concentrate.

How to grow Mandevilla in a pot

  4. Remove the plant from the container and gently tease the roots.
  5. Position in hole and backfill, gently firming down. Water in well.

Growing tips

  • Avoid overwatering as Mandevillas hate wet feet.

  • Ensure you provide the plant with plenty of sturdy support to grow on. Otherwise, tip prune to encourage a more shrub-like habit.

  • For cooler climates try growing M. laxa. This deciduous variety produces fragrant summer flowers and can tolerate frosts down to -6°C. If it is damaged by the cold, cut back completely and it will re-shoot from the base.
     
  • Some mandevillas are often referred to as dipladenias. These plants are considered to be forms of M. sanderii.

  • Wear gloves when pruning to protect your skin from the milky sap.
