Will calla lilies rebloom after cutting them?
No, they will not. They will need a rest period before reblooming. Here is an article that will help you with that:

How much water do Calla Lilies require?
If they are in pots outside, they need to be watered daily and twice a day in temps over 80F. If they are in pots indoors, they need to be watered when the top of the soil is dry to the touch. If they are planted in the ground, they will need 2-4" of water a week.
What if my Calla Lily needs to have flowers cut off? Will they grow back?
They will grow new flowers next year, but likely will not regrow them this year.
I recently planted a calla lily in my garden. I was away from home for a few days, and we had a really warm, sunny few days and I was unable to water my garden! When I returned, the flowers of the lily had wilted and more or less died off. How do I cut these dead flowers, and will they flower again this year? I'm a fairly new gardener and can manage most plants, but these have left me stumped. Thanks. Wendy.
You can simply snip the faded flowers off at the base of their stem.
With calla lilies, it is unlikely they will bloom again. They will likely go dormant soon so that they can build their energy for next year's blooms.
I have spring bulbs that I still haven't planted. Is it too late? I have Calla Lily, Phlox, Ranunculus and Dahlia bulbs that I should have planted in spring. Can I still plant them? I live in Colorado.
It may be too late, but you have to try. They will not survive another year in dormancy. They need to break dormancy so that they can try to store enough energy to survive another winter. You can try planting them in pots so that you can bring them in for the fall and give them a little more time to grow to store enough energy and then you can put them into dormancy again.
Most of my Calla Lilies are doing fine, but some of them, when they begin to bud, the buds form a round fuzzy "knot", which I think is preventing them from blooming. I keep them moist and in the sun. Sometimes the leaves turn brown as well, either from heavy rain or overexposure to the sun. . . I'm not sure. I would greatly appreciate any helpful tips or advice. Thank you, Carol
This sounds like a fungus is attacking the buds. You can treat the plants wil a fungicide weekly to keep the fungus away.
My Calla Lily bulbs are planted in a pot every spring (I bring them into the house in the winter and store them in a cool dark place). During the summer they get many blooms, but only a few of them turn white. Most of them remain green. I occasionally fertilize them and I try to keep them watered sufficiently. The plant itself is lush and looks very healthy in all other respects. Why don't the majority of the blooms turn white?
Calla lilies' flowers normally start out green and will gain color as the flower ages. This is normal. If the buds are not opening fully, they likely need more water. 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.
