Sandy your growing season is not much less than mine. They say we are usually frost free after Mother's day but it does not hold true most years. June is my only absolutely safe time. I prefer the tubers because I have flowers sooner and it seems they bloom more the older the bulb.
I am a lazy pot gardener so I do not dig anything up. The the pots are brought inside after a good soaking so there is no bugs hiding. It is easier for me to move the pots outside early spring and if we get a frost I just throw a blanket over them. All my pots are combo pots so I am moving mini gardens outside on the patio and not single plant pots. If something needs color until bloom or when there are no blooms any longer I throw some coleus in the pots.
