This winter I have a problem with my tupidanthus. I grow it as a pot plant at home. About a month ago the edges of leaves started to become black, and some leaves began to roll up. There were no changes in watering - same moderate watering as before. I thought that the reason may be winter lack of light, so I moved the plant to a lighter place about 3 days ago. No changes so far. What would you recommend?
I hope your plant is doing better now.It sounds like your plant was overwatered or allowed to sit in water for too long. It wants the top 2" of soil to dry out before watering again. A bright spot out of direct sunlight is best. Take a look here.
