When to Prune a Bridal Wreath Spirea
Proper timing is crucial when pruning a bridal wreath spirea. Here are the best times:
Spring
The optimal time is right after flowering finishes in late spring or early summer. This avoids accidentally removing flower buds for next year’s blooms.

Step-by-Step Guide to Pruning a Bridal Wreath Spirea
Follow these simple steps for pruning your bridal wreath spirea:
-
Put on protective gloves and safety goggles. Disinfect pruning tools with rubbing alcohol.
-
Examine the plant and look for dead, damaged, or diseased branches. These should be removed first.
-
Use bypass hand pruners to cut off dead and damaged wood at the base, where it connects to healthy growth.
-
Use loppers to remove thicker dead branches. Always cut back to healthy wood.
-
Identify older branches that are more than 2-3 years old. These will appear thicker and woodier.
-
Prune back older branches, removing about one-third of their length. This rejuvenates the plant.
-
Cut back any overlong or wayward shoots to shape the shrub. Aim for an even overall shape.
-
Once blooms fade, prune back stems to just above a healthy bud or branch. This promotes re-blooming.
-
Step back periodically to check for any asymmetrical or uneven areas. Prune these as needed.
-
Disinfect tools again once finished pruning. Water the plant deeply after pruning.
Avoiding Common Pruning Mistakes

Pruning too late in fall or winter, removing potential flower buds
-
Leaving damaged or diseased wood that can compromise plant health

Making cuts too close to the base, which can hinder new growth
-
Shearing or topping the plant into an unnatural, overly formal shape
-
Not pruning enough older branches, leading to reduced vigor
-
Forgetting to prune immediately after flowering, reducing next year’s blooms
-
Failing to disinfect tools between plants, spreading disease
-
Not watering after pruning, stressing the plant further

Temperature and Humidity
This plant is quite hardy, surviving both cold winter and hot summer temperatures in its defined range. It thrives in climate conditions within its USDA hardiness zones (5b-8a). It has no preference for humidity conditions.
Pruning
This plant tends to spread through suckering, so ground suckers will need to be trimmed off if you want to keep the shrubs confined.
If desired, the shrubs can be pruned for shape or size immediately after the spring flowering period. Always use clean, sharp pruning shears. A good pruning routine is to remove all dead wood, as well as some of the oldest stems, all the way to ground level. This will open up the center of the shrub to sunlight to reinvigorate it. Tips of branches can also be trimmed to control the shrubs size.
