My calla lily sometimes has green blooms instead of white. Can you tell me why?
Calla blossoms often start out green when they first open and mellow into white as the flowers age. This is normal and happens to a few different kinds of flowers as well.
I just recently noticed in my flower bed when I turned my mulch, it was moldy. I had planted some Calla Lilies in the middle of spring. One of them had bumps all under the one side. I figured the mold was the cause. I am wanting to plant some tulips and daffodils for next spring, but I was going to remove all the mulch first since I don't want those bulbs to get sick as well. My question is, can I put down potting soil after removing the mulch, and then next spring put in new mulch? I live on a military base, and it is lease agreed that the flower beds in front are to have mulch. Would my idea work, or should I just put down mulch?
I received Calla Lilies for my birthday this Sept. Can I plant them outside and leave them through the winter? I'm in Zone 6b.
Calla lilies will not survive in your area over winter. Here is more information: https://www.gardeningknowhow.com/ornamental/bulbs/calla-lily/calla-lily-winter-care.htm
How do you harvest calla lily seeds and propagate? Is it worth it?
Allow the seedpods to dry on the plant and then harvest the seeds. Plant the seeds in moist, but well-draining, soil. While you can grow them from seed, you should know that they will take up to three years to flower. Therefore, it is generally better to propagate these plants through division.
I thought I was going to get another flower on my calla, but it has a big seed pod. What should I do with it?
If you're not saving seeds, you can simply cut the seedpod off or leave it. Of course, if you save them, keep in mind that seed grown plants will take longer to produce flowers.
When cutting back my calla lily for the winter, I noticed that some of what looked like flowers actually had pods inside. Could these be seeds for new plants? I wanted to possibly plant them to see if they would come up in the spring. Your thoughts?
Yes, these are seed pods, which can be used to grow additional plants. Seed pod are ripe once they turn yellowish and go soft. At this point, you can harvest the pods. Remove the pod from the plant and break it open. Then, take the seeds from the pulp using a plate or collander to catch them and rinsing under water. Dry the seeds and store them in a dry, cool place or plant right away. You can also choose to save the seeds by cutting off the dried seedpod (turns a orange, gold or light green color) and storing the seeds in an airtight container until ready to plant. Of course, seed grown plants will take longer to mature and produce flowers when planted this way verses offsets.
I have an indoor calla lily. Can I spray it to keep it fresh?
I would set it on a pebble tray filled with water. This will help keep humidity up around the plant. Misting the plant will also work, but you may find that it encourages fungus to develop on the plant.
