How to Grow Asparagus from Seed

Absolutely nothing compares to the delectable flavour of fresh asparagus spears harvested straight from the garden. Two thousand years of taste testing have made asparagus one of the world’s most desirable vegetables.

Established plantings can yield for 20 years, so proper soil preparation is essential. Select a sunny site with well-drained soil and work in large amounts of composted manure or garden compost, at least 12″ deep. A soil pH in the range of 6.5 to 7.5 is ideal.

Soak seeds in water for 2 days before sowing 2.5cm (1″) deep and 12.5cm (5″) apart in rows 45 to 60cm (18-24″) apart. Thin the seedlings to 15cm (6″) apart when they are 7.5cm (3″) tall. During mid-spring in the second year, transplant the 1 year old roots 45cm (18″) apart in rows 1m (40″) apart.

A light harvest can be taken in the second year, however, it is best to wait until the third year after sowing to take a regular harvest. Each spring, mulch established plants with compost and feed with a general purpose vegetable fertilizer.
