Years ago when I knew even less than what I know now , I planted a snowball bush and I didn't realise it was grafted and grew a large silver birch instead as I cut the wrong sucker off ! Well , I've just discovered a very healthy sucker from the snowball bush and as it was what I planted originally, I would really like to save it. The same thing happened a few years back but it died. This shoot looks a lot bigger and healthier so I'm hoping to rescue it. What would be the best way ? I would be very grateful for some help please.. Don't know whether to try it in water or plant with a heel or what. I think it would be deemed as a semi-ripe cutting ??? Thanks , Jean.
