When to plant or sow Asparagus?

Asparagus thrives in full sun and well-drained soil, ideally sandy loam that warms quickly in spring. Choose a permanent site carefully—an asparagus bed can remain productive for fifteen to twenty years. Avoid heavy clay or waterlogged ground, which encourages root rot. Before planting, dig the bed deeply and work in plenty of well-rotted manure or compost to improve fertility and drainage. Plant asparagus crowns (one-year-old roots) in March or April when the soil has warmed. Dig a trench about 20 cm deep and 30 cm wide. Create a low ridge of soil along the bottom of the trench, then drape each crown over the ridge so the roots spread downwards and outwards. Space crowns 40 cm apart within the row, and leave at least 90 cm between rows if planting more than one. Cover the crowns with 5–8 cm of soil initially, then gradually fill in the trench as the fern-like shoots emerge over the following weeks, until the bed is level. Water the newly planted crowns thoroughly to settle the soil and encourage root establishment. Keep the bed consistently moist through the first growing season but avoid waterlogging. Apply a 5 cm layer of well-rotted compost or manure as mulch after planting to suppress weeds and retain moisture. Do not harvest any spears in the first year; allow all growth to develop into ferny foliage, which feeds the crown and builds strength for future crops. In the second year, harvest lightly for two to three weeks only. From the third year onwards, you can harvest normally for six to eight weeks each spring.
