Growing mandevillas outdoors
When growing directly in the ground, temperatures must be high in both summer and winter and planting is done in spring.
- Mandevilla planted directly in the ground copes well with direct sunlight.
To boost flower-bearing, remove mandevilla wilted flowers regularly (deadheading).
- It is best to prune lightly at the very beginning of spring to spur blooming.
- Pruning can be done during re-potting.
Spring is the best season for pruning mandevilla. It keeps producing new stems and flower buds during the growing season. Unlike other shrubs, this vine doesn’t create flower buds that need to go through winter to bloom, so you won’t be pruning flower buds away.
If you need to reduce the shrub over the Summer or Fall, it’s also fine – just remember to water so it has enough means to recover from the pruning. Avoid Winter since wounds take long to heal; these let diseases in.
