I'm awaiting the first of my spring-planted Caladiums to emerge. I have a whole row planted here, all this same variety "White Wings" but this one came on super early because it was a potted one I got last year at Lowe's. When I put it in the ground so it would be alongside its siblings, I dug in a bunch of alfalfa pellets, (yes, horse food) and also added a little bit of pelleted fertilizer. The leaves on this plant have doubled in size in just over a week! Biggest one is 16in. long.
I've got to say, everything I've added alfalfa pellets to has just gone gangbusters! That stuff is the best soil amendment I've ever used. All my Caladiums are getting that stuff from now on - now, geez I've got at least 20 more bulbs to plant this afternoon! I might need to hit the feed store tomorrow . . .
