My calla lily plants are left outdoors year round. I have not divided them. They are pink and yellow plants. They are in containers. They grow and bloom but most blooms do not open. Hope you can help.
Calla Lily Blooms Not Opening

If buds are not opening fully, they likely need more water. Increase your watering. They should be watered at least daily and twice a day if the temps are over 80 F, especially if they're in containers. You can also add some phosphorus, such as bone meal, to the soil.
