If your flowering shrubs aren’t blooming as beautifully as you’d like, the issue may not be the plant—it may be when you’re pruning. Knowing the best time to prune flowering shrubs is key to maintaining lush growth, avoiding damage, and encouraging colorful blossoms yearly.
At Brothers Tree service & Landscaping, we work with homeowners across Belfair, WA, Tacoma, and Mason County to bring out the best in their landscapes. It all starts with timing.
Best Time to Prune Flowering Shrubs: Why It Matters
Pruning isn’t just about shaping—it’s about plant performance. Cutting at the wrong time can remove the buds that produce flowers, delaying blooming for a full season.
Here’s how to get it right.
Spring-Blooming Shrubs
Think forsythia, lilac, and azalea.
- Best time to prune: Immediately after they finish blooming
- Why? These shrubs set their flower buds in late summer or fall, so pruning in winter or early spring removes those buds.
Summer/Fall-Blooming Shrubs
Examples: butterfly bush, rose of Sharon, and most hydrangeas.
- Best time to prune: Late winter to early spring, before new growth begins
- Why? These bloom on new wood, so pruning before growth kicks in boosts flower production.
Reblooming or All Season Flowering Shrubs
Some varieties bloom more than once per year.
- Best approach: Light shaping right after first bloom, then deadhead flowers regularly to encourage continued blooms.
Other Factors to Consider
Can You Cut Back Shrubs in the Fall?
Fall is not ideal for flowering shrubs unless you’re:
- Removing dead or damaged branches
- Performing minor shaping only
Heavy pruning risks stimulating new growth, which frost can damage.
When to Cut Back Shrubs in General
Different shrubs have different needs. Some benefit from hard pruning, while others only use light trims. When in doubt, consulting professionals help you avoid costly mistakes.
Best Tools to Use for Shrub Pruning
Using the right bush trimming tools improves results and protects your shrubs:
- Hand pruners: for clean cuts on small stems
- Loppers: for mid-sized branches
- Pruning saw: for thick, older growth
- Shears: for shaping bushes with dense foliage
Don’t forget to sanitize your tools to prevent disease transfer.
How to Trim Evergreen Shrubs with Flowers
Evergreens with seasonal blooms should be:
- Pruned after flowering, not during the dormant season
- Trimmed conservatively, especially in cooler climates like Mason County
Removing too much can thin out foliage and weaken winter protection.
