Asparagus requires a carefully chosen site. It’s a perennial crop that is going to grow in the same spot for up to 20 years. To produce a crop that will give you plenty of spears each year, you need to plant a whole bed of asparagus at one time. (Plant ten plants for each person; one plant will yield 20 to 25 spears each year.)
Plant asparagus at the far side of the garden, where its beautiful whispy ferns make a background border in summer and fall.
Plant 1-year-old asparagus crowns (roots) this spring to begin harvesting spears in two years. Asparagus is not the easiest crop you can grow. It requires thorough soil preparation, space, and regular hand weeding.
Plant crowns in spring as soon as weather is no longer cold and wet. Plant in a sunny spot out of the wind.
Plant asparagus in trenches 8 to 10 inches deep and 12 inches wide. Cover the crowns with 2 inches of sifted soil. Fill in the trench gradually over the course of the first season as the plants grow, never covering the tips—by autumn soil in the bed should be level.
Asparagus ferns will appear in the summer; do not cut these back until they die back in the fall.
