Since the most common cause of rotten leaves is wetness, you should prevent this. When planting a calla, choose a container with drainage holes (€4.00 on Amazon) so that excess irrigation water can drain away. A coaster is also recommended. You should stay away from planters, as moisture tends to accumulate here unnoticed.
