For those that start celery from seed--do when do you pot-up the little seedlings into their own pot that will carry them to plant-out size? I'm thinking after they are maybe ~3" tall?
Thanks!

I initially sow as thinly as I can in 72-cell size containers. I thin to one seedling/cell once a winner is discernible. Once they are a couple inches tall, I check the root systems carefully until it seems they need to be potted up to a larger size container. Not sure how happy their roots are about being disturbed, so I try to keep them as happy as possible. For me, they take 8-10 weeks to reach the size I like to plant outdoors- that doesn't count the rather long time they take to germinate.
