|Can you start Asparagus from seed from last years plants?|
|Yes, you can start asparagus from seed you have collected from your plants. Asparagus seed can be sown indoors in midwinter or outdoors in a seedbed. In either case, soak the seed in tepid water overnight, then plant them. Space the seeds 1 inch apart and 1/2 inch deep. You'll save yourself some trouble by planting your seedlings into a nursery bed rather than into their permanent location in the garden because you'll want to "weed out" the female plants. Only male plants produce good crops of spears.
When danger of frost has passed, harden off your seedlings and plant them in the nursery bed. When the ferns flower, cull the females. Female plants have flowers with large, three-lobed pistils; male flowers are larger and longer than female flowers. Next spring, transplant the male plants into their permanent bed in the garden. It will take 3-4 years before seed started asparagus crowns will be large enough to start harvesting.
Best wishes with your asparagus!
