Planting, care and pruning are steps that will enhance blooming.
Buddleia is preferably planted in fall in order to ensure root growth and thus proper settling in in spring.
- Choose a full sun location for the best blooming.
- Avoid excessively rich soil that would only lead to building up leafage instead of blooming (fertilizer is thus useless, too).
- Follow our guidance for planting trees here at Nature-and-Garden.
- To make a hedge, keep a distance of around 3 feet (1 meter) between each plant and its neighbors.
Technically, it is possible to prepare buddleia through cuttings at the end of summer.
- Snip in summer 6-inch (15 cm) cuttings off new growth wood (only partially hardened off).
- Remove lower pairs of leaves, keeping only the topmost pair of leaves.
- If possible, dip the base of the cuttings in powdered rooting hormones.
- Plant the cuttings in special cutting soil mix.
- Keep your cuttings near light, but not in direct sunlight.
- Keep substrate moist.
- Ensure that the cuttings can’t freeze in winter, and transplant in the following spring.
Take note that buddleia is very invasive and can quickly become a cumbersome friend.
Pruning, and caring for butterfly bush
You’ve got 2 options to prune, both cases are at the end of winter:
- To remodel your butterfly-bush:
Prune the shoots from the previous year’s growth while ensuring the buddleia has a nice bearing.
- To frankly rejuvenate your buddleia:
Cut back as much as you wish, it will grow back even nicer and should bloom even more.
- If you don’t prune the butterfly bush, it will end up growing sparse and leggy instead.
Watering and adding fertilizer
Mulch in the summer helps retain moisture in the soil and also avoids weed growth.
In spring, adding flower shrub fertilizer will increase the blooming.
