pruning forsythia

we've not lived here very long, and have inherited a large forsythia from the previous owners.

When should we prune it? It clearly needs a haircut as it's overgrown and didn't flower very much in the spring.

Thanks for your input!

Re: pruning forsythia

They flower on previous years growth so don't take too much of this years growth or they won't flower much at all.
I think they are supposed to be done just after flowering so might be best to leave until next year now.

Re: pruning forsythia

I usually cut mine back after flowering but due to 2 broken ribs couldn't this year. I've just cut it right back as otherwise I know by next year it will be out of control, I'll have some flowers next year but not expecting a good show.

Re: pruning forsythia

I too cut mine back immediately after flowering then continue to take the tips off throughout the summer to keep it in shape.
Mine was a sad little specimen comprising of two twigs that I purchased for £1 when Woolworths was closing down, it is now about 5ft and a neat lollipop shape .

Re: pruning forsythia

thanks for the advice. Think I might give the bush a haircut later today once the grass has dried up a bit - just so we can walk past it without having to duck!

Re: pruning forsythia

If it was mine I think I would just cut it right back now, if really overgrown to get it in shape. You wouldn't get flowering next year but the year after it would be glorious.

Re: pruning forsythia

I've done it! Cut it back from about 12 feet tall, and correspondingly wide, to around 6' x 6'. At least we can walk along the path now without getting slapped by overhanging branches!
