1. Aglaonema leaves are turning brown.
Browning of leaves is caused due to overwatering or excessive use of fertilizer.
2. Why is my Aglaonema plant drooping?
Drooping of leaves is an indication of improper light or water requirements. Too much of light makes the leaves weak and floppy. Move your plant away from the harsh light to avoid droopy leaves.
3. Why are Aglaonema leaves yellow and small?
Yellow and small leaves are a sign of copper deficiency. Either, the soil is lacking in copper, in which case you need to use a micronutrient spray. Second, cooler temperatures (<18℃) causes the plant to insufficiently absorb and utilise copper, in which case you need to move the plant to a warmer area or in more sunlight.
