i play bagpipes for them. i think they like more manly music. pump water through their pipes and want to kick FMV and take names.
maybe too much water? not enough heat and fresh air? soil too compacted?
one of my Black Madeira was drawing water to the top of the cutting. i noticed what seems like possible mold forming. that's right before i took all the cuttings in cups outdoor since night temp was getting over 50.
now they are all happy. since then the water has dried up, it's showing root to the side of the cup, and growing nicely.. so far. i mist them when the leaves look droopy. when the cup feels light, i water them. since they are outdoor, i don't worry too much about mold or rotting.
out of 3 cuttings i made from 1 long cutting UCD sent, one is in full leaf. other one is putting out leaf now. one is still sort of hanging in there, but has root. that last one is terminal bud. the terminal bud is not opening, but the bud right next/below it is starting to do something.
when the soil looks compacted after few watering, and leaves are looking droopy even after watering, i usually stick tooth pick into the soil and move it around. hoping that will get some aeration going. do this at your own risk.. it might break root or two.. i do this on top of the soil and bottome drain hole.
