How long does a Buddleia take to grow?
Buddleia is a fast-growing shrub that can put on a couple of metres of growth or more in a year, but it can be pruned back to a low framework of stems in early spring. Grown from seed, it is even possible that buddleia may produce flowers in the first year. Overwintering Buddleia can be tricky. Here are some tips on how to best prepare your shrub for the winter season. The addition of an extra layer of mulch helps protect the roots from freezing. Another option would be to dig the plant up, put it in a pot, and put it in a frost-free location.
Do Buddleia have deep roots?
Why is Buddleia (Butterfly bushes) known to be bad? Buddleia, or butterfly bush, is a fast-growing species that can overtake and crowd out native plants if not controlled effectively. Buddleia has deep roots and produces a lot of seeds, which allows it to spread and take over an area easily. For older varieties of butterfly bush, it can be helpful to deadhead them to keep them from dropping viable seeds and to help quicken or promote rebloom.While the temptation to tidy up the garden in the fall is strong, gardeners in our climate should exercise caution when it comes to pruning butterfly bush. By waiting until early spring to prune, you can protect your plants from winter damage and set the stage for a season of spectacular blooms.In these natural areas, the butterfly bush becomes an invasive plant. It’s considered a noxious weed in some regions because it can out-compete native plants and destroy habitat. Native plants are crucial host plants for local caterpillars and other pollinators.Butterfly bush is best planted in the spring or fall. If planting in fall, make sure to get them in the ground well before first frost in order to develop a good root system before colder temperatures set in.The average life expectancy of a butterfly bush is 10-20 years. Consequently, once older bushes begin producing fewer flowers, it is time to consider replacing them.
Where is the best place to plant buddleia?
All it needs is a sunny, open position and to be pruned hard in early spring. The plump nectar-rich flower spikes of this fast-growing deciduous shrub are very attractive to pollinators, especially butterflies. When should I prune butterfly bush?

At this point in time, the summer lilac is not in sap and there are no birds or other creatures nesting in its branches.Left unpruned, large butterfly bushes can become “second story” plants: their flowers form way up at the top so you can’t enjoy them unless you have a second story window. The warmer your climate, the more you should cut back your butterfly bush each spring.Butterfly bush cuttings should be taken in the spring or summer to be rooted and planted before winter. It will take several weeks for roots to grow, and the young plant needs time to settle in before colder temperatures arrive.Fall is not the time to prune butterfly bushes. Though they may be lightly trimmed in autumn to remove any flower heads (and along with them, any lurking seeds) and neaten them up a bit, spring is far preferable for pruning.
