I bought 15 mixed pack of caladiums tubers. I planted them 3 weeks ago. How long does it take for them to start growing? I planted them apart from each other, in potting soil.

It really depends on the temperatures and water they are getting. Water them when the top of the soil is dry to the touch and give them a little more time. It has been a somewhat chilly spring, so they may not be as fast to sprout.
