When Should Allamanda Be Pruned?

The best time to prune most allamanda varieties is mid-spring, before they start to bloom. You can trim them back here and there any time of the year, but doing heavy pruning in spring should help give the best display of blooms.

How do you make allamanda bloom?

Fertilize in spring through summer every two to three weeks with a good blooming plant food. Allow the plant to rest in winter.
