Mary Washinton — Approx. 60-75 sds/pkt. A trusted, reliable variety introduced in 1949 that produces vigorous, medium green, mouth-watering spears that are excellent fresh or quite suitable for freezing. It is an heirloom vegetable that is one of the older and more common asparagus varieties, with good resistance to asparagus rust and wilt. When fully established, asparagus plants can produce yields for 20 years or more.

OSC® Asparagus Seeds
Select a sunny site with well-drained soil and work in large amounts of composted manure up to 12” deep. A soil pH in the range of 6.5 to 7.5 is ideal.
Planting: Soak your asparagus seeds in water for 2 days, then sow seeds 2.5 cm (1”) deep and 12.5 cm (5”) apart in rows 45-60 cm (18-24”) apart. Feed with a general-purpose vegetable fertilizer such as granular 4-12-8 or soluble 20-20-20.
Thinning: Thin the seedlings to 15 cm (6”) apart when they are 7.5 cm (3”) tall.
Transplanting: During mid-spring in the second year, transplant the 1-year-old roots 45 cm (18”) apart in rows 1 m (40”) apart.
Harvesting: It is best to wait until the third year after sowing to take a regular harvest. Each spring, mulch established plants with compost and work in large amounts of composted manure 30 cm (12”) deep.
