Broom (the bushy, yellow flowered plant) is a shrub and I would not have thought that it could be split at all.

Bulbaholic's right - not only can you not do it now, it can't be done at all.

Even moving an established one is a death sentence for them.

My broom shrub has gone completely brown. Has it died or is it just resting?

As broom is evergreen, Avril, I am afraid that it may be a gonner. Break a piece off and see if the wood is green or dry and brown.

Thank you B. The wood is dry and brown so it's a gonner.
It was a fair age so I've had a lot of broom from it.

Broom - broom! (sorry)
