Bonariensis does grow slowly right now....seedligas, young plants and mature plants are only just beginning to quicken in growth.
Only pot on when you see roots at bottom of the tray otherwise leave them for now. However, pot on into small pots when these roots are seen and pot on again when roots are visible. They will grow vigorously very suddenly with greater day length and extra warmth. I add plenty of perlite in compost mix for bonariensis.
Hi, I'm new to the forums so please forgive me if I've asked this question in the wrong area.
I planted V. bonariensis last Spring and they grew brilliantly, however, even though I didn't cut the plants back, there's absolutely no sign of any new growth. Do you think it's still early yet, or, have I lost them? I'm just South of Glasgow if that helps. Any advice would be much appreciated, thank you.
