Re: Rooted Cuttings Failure Question?

However because all dropped leaf cuttings are toast for this year - binned last one today - I was restricted to changing out cuttings that have the original leaf after ~3 1/2 months, but no new "leaf growth".

Re: Rooted Cuttings Failure Question?

Txs, for the suggestions. I am going with change soil for this years slow ones where cane still green. Use potting mix (sterilized on label) and heavy on vermiculite 50%.
