Plant the Asparagus Plug Plants as soon as possible after receipt but not if the soil is waterlogged or frosted. Handle the plugs carefully to avoid damage and do not let them dry out.
Plant in separate rows, setting individual plugs 40-45cm (15-18") apart with 1.2m (4ft) between rows. For each row dig a trench 30cm (12") wide and 20cm (8") deep. Replace some of the soil to the bottom of the trench to form a mound or curved ridge 10cm (4") high at its tallest point. Plant the plugs into this trench so the top of the plug is just covered with soil. Water well to ensure the plants do not dry out. Gradually fill the trench with soil as the plants grow. When the cropping stage is reached, a 5-8cm (2-3") layer of soil can be mounded over the crowns in the autumn after the crowns have been cut down. Repeat as necessary, in subsequent years.
After planting, apply a general fertilizer, such as Growmore, at 100g per sq. metre (3oz per sq. yard). Hoe it very lightly into the surface, taking care not to damage or disturb the newly planted plugs.
