How to Grow

Hare's Ear seeds can either be sown directly outdoors or started indoors to get a jump on the growing season. With either method, the seeds should be kept moist until germination, which will occur in 14-60 days (can be erratic). If starting indoors, sow the seeds into small pots or packs 6-8 weeks before the last expected frost. Once seedlings are established, they can be transplanted directly outdoors after frost danger has passed. If sowing directly outdoors, plant in well-drained, loamy soil in an area of full sun after the frost season is over.
