|I planted my caladium bulbs many weeks ago, right after Burpee sent them. They sat in the basement for about 6 weeks(planted in pots) and as the weather got better I put the pots on the back porch. Nothing has happened yet and I am afraid it will be so late when they sprout that the summer will be half over. Last year I tried the same thing and many of the bulbs had rotted. I ended up getting plants from the nursery and vowed not to do this again, however, I did. What can I do to speed up the process so I know whether to go to the nursery again, or not? I planted them with about 1 inch of dirt on top. HELP!
