Firstly, I wondered whether it's ok to keep cuttings ticking over in my vitopod without any vent opening? I've had cuttings in there for 2 wks now but there is no rooting to speak of I don't think, though one or two specimens are showing some signs of little green shoots (lilac and spirea), one spirea cutting actually has some aerial roots maybe 7mm long from where two stems fork / branch, never expected that! I'm honestly not sure as to whether I should be opening vents or not or whether cuttings can grow for a few months without any ventilation.
Second, is someone able to help me group these plants according to when they would be expected to root? Rooting times for groups would be helpful also.
Spirea, viburnum tinus, verbena bonariensis, lavender, hebe, rose (young soft growth), euonymus alatus, geranium (perennial), heuchera, buddleia, acer palm,atum, syringa vulgaris, hydrangea, fuschia
