When Do Butterfly Bushes Bloom?
Butterfly Bushes have a long bloom period from summer through fall. In most areas these flowering bushes bloom from June or July to September. The blooms often persist later and arrive earlier in warmer climates.
How to Plant Butterfly Bushes
Start by watering your plant thoroughly in its pot. Next, dig a hole twice the width of the root ball and not quite as deep as the root ball is tall. Place your plant level in the hole. The top of the root ball should be slightly higher than the existing soil line. Backfill with the soil you dug out. Water deeply until the water begins to pool on the ground surface. Apply 1 to 2 inches of mulch to reduce watering needs. Water daily for the first week, 3 times per week the 2nd and 3rd week, and 1 to 2 times weekly thereafter for the first 2 to 3 months until your Butterfly Bush is established.
How to Care For Butterfly Bushes
These flowering plants tolerate full sun and part shade and are adaptable to a variety of soils as long as your soil is well drained. If your soil is nutrient rich your Butterfly bush will not require fertilizer. Fertilize in early spring and when planting if your soil is lacking. Choose a balanced, slow release fertilizer. Water well when your plant is newly planted and during establishment, After establishment these shrubs are drought tolerant and only require watering during dry, hot periods. Butterfly bushes don't require pruning, but these shrubs do tolerate heavy pruning if you choose to do so. Mulching is a good choice especially in colder regions to protect the roots from freezing temperatures and help the soil retain moisture.
When to Prune Butterfly Bushes
Pruning Butterfly Bushes should be done in winter. They bloom on new wood so there is no need to worry that you will remove flower buds at this time. Minor pruning (a snip here and there) or deadheading can be done at any time.
How to Prune Butterfly Bushes
Since these shrubs bloom on new wood and are fast growing most experts recommend pruning them back to the ground in winter. This is definitely a good option in cooler climates where your plant will die back to the ground anyway. Here in the south, Butterfly Bushes can actually become large woody shrubs. So it is up to you. If you want fresh lush, prolific growth on a woody base skip the heavy pruning. If you prefer your whole plant to be new herbaceous growth with flowers evenly dispersed over your entire plant, prune away! The harsh prune will encourage vigorous growth. With some older varieties deadheading can encourage reblooming, but it is unnecessary with newer varieties that rebloom well without pruning.
