Do butterfly bushes need to be cut back?

Butterfly bushes do not need to be pruned every year. But since butterfly bushes only bloom on new growth many gardeners prune them severely each spring to encourage lots of new growth and lots of flowers. You can prune this shrub back to twelve or twenty-four inches high. For most plants, that's a drastic reduction.

How deep are butterfly bush roots?

They are supposed to be six feet deep. Therefore, I can't plant anything there unless #1 I don't care if it gets dug up/can be easily transplanted (in the event the pipes have problems and they have to dig up to get to the pipes; not a likely event) and #2 won't root deep enough to interfere with the pipes.

Why is my butterfly bush dying?

If the wilting leaves are shriveled and brown, the butterfly bush is suffering from lack of water.

Can I prune Buddleia in autumn?

Ideally, do so in the early spring (after the last frost). This is best time to prune your buddleia but I experimented last autumn and cut ours down to 2.5 ft and it came back lovely and healthy this year! However it may not be advisable to prune after September in your area, so take care.

Can you keep buddleia small?

When it comes to growing buddleias (or buddlejas) there's a wide range on offer and they vary in habit and quality. It's better to opt for compact varieties rather than the tall rangy ones. However, larger varieties of buddleias can be kept compact with hard pruning in March.
