Hi guys,
I would like to ask you for your opinion on my plumeria plants. I bought them as cuttings this May so had to root them first (using rooting hormone). Once roots developed, I transferred plants into pots containing soil for cactus. During next few months of growth (glasshouse), new leaves developed and plants looked healthy. Now, during autumn, leaves are falling off and tips are turning black. I went through some forums on plumeria and it seems plants could be infected with black tips fungus. Do you think this is really my case or are just plants going dormant and this dark colour of tips is usual? Plants have been grown at glasshouse with temperature range from 20-25°C.
I live in the Czech Republic (central Europe) with temperate climate.
Many thanks for your help,
Bart.

Welcome! Bartolomej

It does look like black tip fungus. Very strange considering your greenhouse temperatures Confused

Thanks for your quick response. Yeah, it seems bit strange for I learnt that black tip fungus prefers lower temperature. Anyway, I will spray both plants with fungicide and see if it helps. Do you think it would be better to remove those black parts if fungicide has no effect?

Keep an eye on it and if it seems to be spreading then definitely cut, and clean your knife/clippers between cuts and keep cutting until no more rot is visible.
Sometimes the black tip will 'seal' itself and than you don't need to do anything.
