In the fall of 2013, I decided to lift and divide a fairly large group of Red Alert from which I had purchased a few from B&D a few years earlier. They multiplied profusely. Of the group, I got about 140 blooming size bulbs, kept about 40 for myself and gave the rest to a Goodwill to pass out. Left over were about 80 to 100 real tiny offsets that were too small to give away--varying in size from a BB pellet to your small fingernail. So, I made shallow trench about 6 inches wide and sprinkle planted them (just like peas). They're doing very well. That Goodwill's going to love me!
