When to Prune Butterfly Bush
The best time to prune butterfly bush is in the spring, after the final frost but before new growth emerges. This allows you to remove any winter damage and invigorate the shrub, encouraging it to put out fresh, vigorous shoots for the season ahead. Aim for late winter or early spring depending on your climate.
Some gardeners in warmer climates (zones 8 and 9) may do a light pruning in the fall to tidy up the plant for spring. However, spring pruning is generally sufficient.

Pruning vs. Deadheading: What’s the Difference?
These terms often get tossed around together, but they serve different purposes:
- Pruning tackles unproductive areas of the plant, like dead, diseased, or leggy branches. It also shapes the overall size and form of the butterfly bush.
- Deadheading involves removing spent flowers throughout the growing season to encourage new buds to emerge.
Both techniques contribute to a healthy and thriving butterfly bush!
Step-by-Step Guide to Pruning Butterfly Bush
Ready to unleash your inner pruner? Here’s what you’ll need for prune butterfly bush:
- Bypass pruners: Perfect for making clean, angled cuts on small stems and shaping the shrub.
- Bypass loppers: For tackling thicker, woody stems with new growth.
- Gardening gloves (optional): Protect your hands from thorns and scratches.
Step 1: Prune Above Healthy New Growth & Remove Stems
- Locate large leaf buds or signs of new healthy growth on the stems.
- Make angled cuts with your pruners or loppers just above these healthy buds. The angle should slope slightly away from the bud to promote proper water drainage.
- Aim to remove ⅓ to ½ of the overall stem length, depending on your desired level of rejuvenation. A more drastic prune will encourage bushier growth, while a lighter prune will maintain the current size and shape.
- Remove any dead, diseased, or weak stems entirely. These won’t produce flowers and can detract from the plant’s overall health.
Step 2: Examine and Water Thoroughly
- After pruning butterfly bush , give a thorough inspection. Remove any remaining dead or diseased foliage.
- Since pruning can be thirsty work for the plant, water it deeply and thoroughly. Continue watering about one inch per week during the peak growing season.
Step 3: Deadheading for Continued Blooms (Optional)
While not essential, you can further encourage vibrant blooms throughout the growing season by regularly deadheading spent flowers. Simply snip off the faded flower heads to make way for new buds to emerge
