I had a similar problem with one of my red leafed philos labeled by the
vendor as "Bloody Mary". A friend advised increasing the humidity
quite a bit combined with regular misting of the emerging leaf, and
that alleviated the problem. I can't tell you how much the humidity
changed because I don't have a hygrometer (or whatever they are

Subject: [Aroid-l] Discussion of Aroids, Philodendron andreanum
Growing successfully a wide range of rare Philodendrons, I have
problems with P. andreanum.
They are very strong growers under good conditions in greenhouse
culture. But each new leave gets stuck in the bud.
Rhen it rips and opens up deformed (often the leafstalk breaks
through the leafblade).
Does anybody have an advice, how to get out of that problem?
Thank You in advance
And Good Growing
