Clematis 'Bill MacKenzie' problems — and how to fix them
Clematis 'Bill MacKenzie' (Clematis 'Bill MacKenzie') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Excessive vigour
Can quickly overwhelm small spaces and weaker plants. Give it a large support and hard prune annually as Group 3 to keep it in bounds.
Self-seeding
Abundant seedheads scatter viable seed. Remove seedheads if you want to prevent volunteer seedlings, or leave them for winter display.
Wet, heavy soil
Dislikes waterlogging and may suffer root problems in soggy ground. Improve drainage before planting in heavy soils.
Late spring growth
As a Group 3 clematis it breaks late from low buds; bare stems early in the year are normal, so wait before assuming the plant has died.
