Is it possible to divide a small clump of Verbena bonariensis. I have several small clumps now, they'll be about 3 years old. So it would be handy if they do split so I could have several more plants. Cheers.
It might be difficult to divide that clump without damage. Mine seed themselves all over the place and babies are easy to move. I'd wait a bit and look for seedlings.
@Posy...I often hear about how they are prolific self-seeders, but in the 3-4 years I've been growing them, I have never had a single self-sown seedling.
The normally branch from a single stem, I think they'd be hard to divide. Probably better to wait until they form new shoots in the Spring, and then do some cuttings. They take readily.
Wait until it's starting into growth with buds, then lift and cut it into sections or pull off (brutally!) bits of stem. You want bits of stem with signs of growth, attached to bits of root. Basically this is what is politically incorrectly called 'Irishman's cuttings'. A bit easier and quicker than stem cuttings. Pot on and give a bit of TLC to start with. Although... you could probably get away with planting larger segments straight out.
