Why Pruning is Essential
Pruning accomplishes several important objectives:

When to Trim Mandevilla Vines
Timing is critical when pruning mandevillas For shaping and rejuvenation, prune in late winter or early spring before new growth emerges. Never prune fall through winter when plants are dormant.

Pruning Tools You’ll Need

- Gloves for protection
High quality tools make pruning easier and minimize damage. Clean tools thoroughly between plants.
How to Prune Mandevilla Vines Step-by-Step
Follow these simple steps for successful shaping and rejuvenation pruning
1. Remove Dead or Damaged Growth
First, cut out all dead, diseased, or broken stems to improve plant health. Make cuts just above healthy buds.

Next, identify branches that are overgrown or undesirable. Prune these stems back to just above a leaf node.
3. Shape and Contain Growth
Now shape and contain growth by selectively trimming stems. Cutting back tips encourages bushy fill-in.

Carefully thin overcrowded interior growth to allow air circulation and light penetration.
5. Tidy Growth on Supports
Finally, neatly trim back growth wandering away from supports to maintain optimal coverage.
Summer Maintenance Pruning
To maximize flowering:
- Deadhead spent blooms just above foliage
- Pinch back shoot tips to encourage branching
- Lightly thin as needed to improve air flow
Avoid heavy pruning in summer.
Training Young Plants
Pinching back and trimming new shoots trains young vines. Remove weak or awkward stems. Guide selected stems onto supports.
Post-Pruning Care
Once pruning is complete:
- Disinfect tools to prevent disease spread
- Water and fertilize to aid recovery
- Inspect regularly and prune as needed
- Train new growth onto supports
Proper follow-up care keeps plants vigorous.

Should I Cut Back Mandevilla?
This is a commonly asked question with a resounding, yes. Knowing when to prune mandevilla vines is key to continued health and vigorous blooms. Cutting back a mandevilla vine is best done in late winter or early spring, before the plant starts to produce new growth.
Mandevilla vines put out new growth faithfully and quickly, and the summer’s flowers all bloom on this new growth. Because of this, cutting back a mandevilla vine drastically wont hurt it or particularly affect its summer display, as long as you do it before it puts out its new shoots.
You can cut back old growth or branches that are getting out of hand straight down to the ground. They should sprout new strong stems in the spring. Even branches that aren’t getting unruly benefit from being pruned somewhat, encouraging new growth and giving the whole plant a bushier, more compact feel.
A single stem of old growth that’s cut back should sprout several shoots of new growth. Cutting back a mandevilla vine can also be done during the growing season. You should never prune new growth vigorously, because this will result in fewer flowers.
You can, however, pinch off the ends of new growth early in the spring, once it’s reached a few inches (7.5 cm.) in length. This should encourage it to split into two new shoots, making the whole plant fuller and more prone to flowering.
