Different plants need to get into the ground at different times. But
let's assume that I don't want to plant on 16 different dates, for each
plant's optimum planting time. So, roughly speaking, how do I know when
I should plant spring flowers?
One time a couple of years ago, I called the weather forecaster at the
local TV station and asked him when he's going to plant.
What do you advise?
