Growth Requirements: Sunny, sheltered location produces best results. Requires adequate water through summer months from November to May. The Allamanda is best suited for subtropical to tropical climates as it is frost sensitive.
Uses: Ideal for growing over walls, fences, pergolas or on trellis.
Maintenance: Directional pruning may be desirable in the early stages. May prune heavily in spring to maintain density and encourage flowering. A fertilizer high in P (phosphorous) will be beneficial as Allamanda’s are heavy feeders due to flowering. Feed in spring, summer and autumn.
