Need some cutting advice. I was given a couple of N. x coccinea cuttings. I potted them up in lfs/perlite/vermiculite/peat about 5 weeks ago. My temperatures are highs 75F lows 55F. Humidity remains above 65% during day and 80% at night. I realize this is a lowland highbrid and my conditions are more highland conditions. One of the two cutting is the apical meristem cutting and it is continuing to put out new leaves. Each new leaf begins sending out a tendril but the tendril turns black and the new leaves are droopy. The other cutting is remaining green and seems to have an activated node because I can see the swelling but no new shoot. Are the night temps just too cold or should I just continue being patient? Should I try and find a warmer spot for the cuttings?
