Planting Crosne

Prefers a full sun location in rich, sandy, well drained and fertile soil with a 6.6 to 7.5 soil pH. Crosne is started by dividing rhizomes, tubers, corms or bulbs (including offsets), but not by seeds. In spring when the days are warm and nights still cool, set bulbs directly in the garden at 3 inches deep with 12 inches between plants.

Growing Crosne

Water regularly but do not over-water. Plants should never be allowed to flower; causes crosne to develop bigger tubers to harvest. When the foliage reaches about 1 foot tall, cut it back to 6 inches or less.

Harvesting and Storing Crosne

Harvest after frost kills the foliage; leave crosne tubers in the ground until needed. Tubers should be pale and firm, not rubbery, when dug up out of the ground. Scrub tubers to remove dirt. Can be stored in an open basket or refrigerated for about a week. Eat raw, put in salads, or stir fry. Tubers can also be pickled or dried, for later use.
