Step-by-Step Growing Guide
Asparagus is a 20-year investment that rewards patience. Plant one-year-old crowns in early spring, as soon as the soil is workable, in a permanent, well-prepared bed. Dig trenches 30cm deep and 30cm wide, spacing 40–45cm within rows and 120cm between rows. Mix the excavated soil with generous aged compost, a cup of rock phosphate, and a balanced granular fertilizer. Set crowns in the trench, spreading roots like a spider, and cover with 5–8cm of amended soil. As ferns grow, fill the trench gradually. Asparagus demands excellent drainage (wet crowns rot) and pH 6.5–7.5 — it is one of the few vegetables that tolerates slightly alkaline soil. Do not harvest for the first 2 years — let ferns grow to establish the crown. In year 3, harvest lightly (1–2 weeks only). Full harvests begin year 4. Feed with balanced fertilizer every spring and again after harvest season.
