My calla lilies bloom green, no color in the flowers. What am I doing wrong? When I bought them they had color. Then as the summer went on they came up green and stayed that way.
Nothing wrong. Calla lily flowers often start out green and develop their color as they grow. The color should appear shortly.
Instead of digging up and storing the roots, can I just bring in the potted plant and store it in a dark place while I'm gone during the winter months? I'm usually gone for 6 months, so should I begin watering it and set it outside when I return?
Yes, you can. Once warmer weather returns, you can set the pot back outside and resume regular watering and fertilizing.
When I just planted them this summer, they had two flowers. Now I have several flowers, but all of the new ones are drooping. They look so sad and it's making me very sad!
It may need more water. They are water hungry plants. Increase watering. If they are in containers, you may want to water several times a day.
I was told that a cat could die if exposed to a calla lily. Is this true?
They are only harmful to cats if the cats eat them. They are fine being around them, they just can't snack on them. Normally cats leave plants alone, but if you have a cat that likes to nibble plants, you may not want to grow this plant.
Will Calla Lilies re-bloom after being cut?
My calla lily plant is blooming beautifully. However, I would like to enjoy it inside the house and at work. I'm worried that it will stop blooming after I cut off two or three. The summer has just started and I don't want it to stop blooming. Please help.
Calla lilies only bloom once a season. If there are unopened buds, they won't be affected by cutting those that are already opened.
