I have several very healthy V. bonariensis seedlings - roughly two to three inches (in old money!) high. Should I pinch out the tops or let the little plants get a bit bigger. They are now in individual pots as I will not be planting them out into the garden until next year. Would welcome advice please.
Cacoethes: An irresistible urge to do something inadvisable
As Verdun says. I would pinch out at slightly larger than they are at the moment.
Thank you so much Verdun and fidgetbones. I really appreciate your advice. They can keep their heads for longer!
Once they get old and woody, I chop them right down. If they look rubbish in the spring, I hoik them out but if they're bushy and reasonably lush, I leave them.
Thank you for that tip too B3. I do have mature plants in the garden so I'll keep a watch out on those.
They are lovely Verdun. Give a nice airy feel to the garden and I love the purple colour!
