The Q&A Archives: caladiums

Question: Hi!
I live on the northern edge of Zone 4, so know I can't start caladiums outside yet. I've read that you can start them indoors, then transplant outside, to give them a jump start, and this is what I'd like to do. I'd like to start them in 6-8" pots, then just sink the pots outside in about 3-4 weeks. Will this work? Is that size pot big enough? How deep do I put the bulbs? I figure 1 bulb per pot. Can I also do this with large dahlias, and callas, and any other tender bulbs? Sure appreciate any help you can give me. Thanks! Terri Lynch

Answer: Yes, you can do this with all of those bulbs, but you need bigger pots. I would go for at least 10-12" for the best growth. Each bulb has it's own planting depth, but the ones you mention usually go an inch or two beneath the surface. Check packaging to verify planting depth. You are correct that you should put only one bulb in each pot.
