seriously? I can't remember when I started them last year...my memory is failing me. I want to say it was Valentine's day, but it might have been St. Patrick's Day, LOL. I always pot up to the bottom of the container from Jiffy Pellets to a paper cup to cut-off 1 liter bottles, and they were less than 1' (with huge root systems of course).
Well, I will be the one pulling up to the plant swap in a landscaper's truck.
