so, yesterday, i found 3 of my 1 gal pots with dead cuttings.
i had 1 KB cutting with one node stuck in the pot. found out the bud it had was rot. i pulled it out and the roots were still good, so i planted it again in hope it will do something. this one was due to over watering.
my Paradiso Nero Mario was doing well till aboutt a week ago, it was semi-hardwood sucker. found out that the all the barks under the soil was coming off.. but the roots still look ok and had one green bud coming off. i planted it again. it was due to over watering.
now.. RdB. it was green cutting. this one died few days ago. i pulled it out and this one was bone dry. the whole length of the cutting was dried up. there were plenty of water in the soil. probably i should have kept it in the controlled env where the moisture was plenty.
so what have i learned. 1) don't water until the soil is rather dry. 2) if it's green cutting, keep it in controlled env until the cutting is hardened and will not dry out.
but here is the funny thing. other RdB which is mostly hardwood given same amount of water at same time is growing wonderfully. Salce which was started at the same time with Paradiso Nero Mario is also doing well with same watering and so on along with Fico Preto, and Socorro Black.. i guess some cuttings are just not meant to be.
