Asparagus Overview

Asparagus have beautiful featherly green leaves in Summer after the Spring spears have been left unharvested. It only grows in the warm summer months and becomes dormant in winter. The crowns need about two years to grow strong enough to produce sizeable spears, but can be harvested after that for many years. They need a cold winter and cool spring for best production.

Common problems with Asparagus

Asparagus falls under attack by fungal pathogens, so be sure to plant it in soil that has a good drainage and allow deep watering to encourage a deep and healthy root system. Asparagus beetles can harm plants.

How to harvest Asparagus

Harvest the new shoots that emerge in spring and early summer months and cook and enjoy fresh. Leave some spears to grow into foilage for next years' harvest. Leave the first two years to allow the plants to grow strong before harvesting! To harvest white asparagus add soil around the spears to eliminate sunlight.

How to propagate Asparagus

Seed

Sow seeds after fruits have ripened (when they are bright red). Be sure to remove the fleshy seed coat of the seed before placing under 1 cm of soil and keep moist.

Division

Division of large crowns can be done when lifted in the dormant period (winter months).

Other uses of Asparagus

It was once an official medicinal herb, noted for its diuretic and laxative properties.
