Q.leaves and flowers of calla lily getting brown
Why are leaves and flowers of calla lily getting brown? I bought a healthy looking plant a week ago. It is kept in a conservatory and has been watered regularly. Now the leaves and flowers are looking brown and fading.

Calla Lilies do not like there roots to sit in water.
You may be overwatering. Your plant should have a well draining pot. Soil damp but not soggy. Feel the soil before watering.
Also the light conditions may have changed from the greenhouse to your conservatory. They do like full sun.
Here is a link with more information.

Every time I water they fill up with water and fall off,try watering very little still same.
