“I just moved into a new house and will be removing a butterfly bush. How much of the root ball do I need to remove so it doesn’t come back?” Question from MaryAnn of Portland, Oregon
Answer: Though beautiful, standard butterfly bush (Buddleia davidii) tend to be very weedy and invasive, which is why gardeners often remove it. Remove the whole root system to make sure that it does not come back. The process will require sharp hand pruners or loppers, good garden gloves, and a sharp, heavy spade. Cut back all of the top growth, so you don’t have branches in the way when you start digging. Then dig deeply around the rootball, and pull it up when it’s fully loose. It should not be too difficult. Butterfly bushes don’t have very dense, deep root systems, so they are fairly easy to remove. Let me know if you want any ideas for replacements!
