To get your Asparagus bed started you
will want to select an area of your garden that can be left alone
for many years. Because, unlike most other vegetables, Asparagus plants
can live a long, long time.
Asparagus should be planted in soil that is deep with organic
matter. Plants should be 12 to 18 inches apart in rows that are 3
feet apart. Plant the potted plants at ground level and not in a
trench like you would a bareroot crown. Asparagus plants will spread
horizontally along the ground as the years go by. If you plant them
too close together they will crowd each other out.
As the plants get
older the spears will get thicker. It will be the third year before
you get any kind of real harvest. Only harvest about half the first
few years so the plant can produce energy to spread. No spears, no
Spears should be harvested by bending near the ground and snapping.
This is the best way to avoid damaging other spears not yet ready
Be sure to keep your Asparagus bed weed free and fertilized well. In
the fall, cut all ferns back to the ground and clean up fallen
debris. Remove any plants that make berries (pretty rare). Apply a 2 to 3 inch layer of compost over the bed. This will
help to suppress weeds that germinate in the spring.
A mature asparagus plant can produce between 1/2 to 3/4 of a pound
of spears. One person who really likes asparagus can use about 20
plants all their own!
