Celery: these are very tiny seeds, and we strongly recommend transplanting them. They take 4 to 6 weeks in trays and then around 75 to 85 days after transplant. The good news is you can get lots of celery from a little area--about two bunches per square foot, and even more in a raised bed! All our varieties are Heirloom, open-pollinated, Non-GMO, and self blanching!!
