I hope I'm in the right place to ask about calla's. I had a potted calla in winter that produced blooms for many months. When it seemed to stop blooming and appeared to be declining, I put it aside in my garage to dry out, maybe 3-4 months ago I just checked to see how the bulbs looked and they are plump and seem to be trying to spout. Can I now plant them in my outdoor garden at this time of year or is it to late? Any suggestions will be appreciated. I really want to grow them in my garden. I'm in N.GA Zone 7a thank you.
