When I say I have a trick, here it is. All over town now the bagged plants are being marked down in the big box stores and big home improvement stores. Some as much as 75%. That’s when I shop for callas. I purchased 6 tubers the other day. Make sure the tubers are firm and not mushy. Immediately plant them in a pot and water well. I usually plant mine about 1-1/2 to 2 inches deep in a good potting mix and keep the soil damp, not wet, until the tubers start emerging. Lay the tubers flat with the bud right side up. I lightly fertilize with liquid feed when the foliage unfolds. By mid-summer I will have flowers if allowed to grow in filtered shade. Once the blooms are finished I transplant them into the garden or allow them to grow in the pots until a freeze is predicted. Then I bring them in to dry, until the danger of frost has pasted next year. I then bring the dry pots out, water, and when they start growing, I liquid feed them about every 2 weeks until they flower. Now there is another way. This time of the year a friend of mine has had success by watching for the plants that have finished blooming at stores. He buys them at a reduced price and plants them in his garden. If the clump’s roots are matted you can divide, but I like big clusters. So if I did it this way, I would plant the whole plant, again, in high filtered shade and rich well drained soil. So the trick is simple. Buy on sale and enjoy them late.
