I have a 20 year old forsythia bush that has been pruned each year, but now has grown very woody. How low can I prune it without killing it off!



Wait until it's finished flowering and cut out 1/3 of the old wood - especially any branches that are crossing each other or growing inwards.
Cut the rest down by 1/3 when the plant is dormant (ie when it's lost its leaves but before it starts budding next spring) then pruned out 1/3 of the old wood each year.

If you stick some of the prunings in the ground they will probably root quite easily too.

they are tough plants, mine was very woody, cut it right down thinking of having a change. but it shot new stems from the ground. did put up with rejuvenated bush for two years, but finally dug it out to plant a new rose, have kept a cutting though, just in case?
