Sunsi, I start 6 celery plants in cells in early Feb. and then keep sowing every month through May. The nurseries around here have plants available around July 4th so I think you still have time. I'm germinating some now along with brussel sprouts.
Ventura is my favorite so far for consistently nice plants and when it comes to fresh eating because it's not strong and I don't blanch. I usually devour the inner stalks and dry the outer ones or use them in cooking.
The plants have done well both in the ground and in raised beds. They like rich moist soil and will attract slugs/snails so I sprinkle Sluggo around and keep an eye on them.
I've had good luck drying it and also freezing after sauteing for use in soups, stews, but I prefer drying because of limited freezer space. When rehydrated it cooks up just like fresh.
Good luck- I think you'll really appreciate your own homegrown celery.
