Frangipanis are low-maintenance. After they are planted in the ground, they will most likely get all the nutrients and water from the local soil. It’s possible to prune frangipanis but frangipanis will keep a nicer appearance if their branches are not pruned. If a branch is broken off by a child or pet, the frangipani, especially if established, will continue to grow.
During the initial years, it’s best to monitor your frangipani plant in case any problems arise. Small frangipanis can weaken and die in unfavourable conditions.
