Asparagus:
Fresh Bursts of Garden Goodness
by: Liz Roberts
Nothing brightens up a spring table than a plate of asparagus.
Its’ color bursts with the promise of a verdant season ahead
while its’ taste bursts with tasty freshness. Having just
picked asparagus is easy. Any green thumb can handle cultivating
the stalks. They're relatively simple to plant and maintain.
Before you select which type of asparagus to plant, you’ll
have to clear away a good sized area for your stalks. Once they’re
established, they will take over your garden. The best soil for
asparagus is a well drained sandy loam. You can plant them in heavy
clay soils too, but only if the top layer is of good depth and
there has been an abundance of organic matter incorporated in it.
It should be a deep soil, free of rocks and gravel. Asparagus can
grown in any pH level, however the best for it is one between 6.0
and 7.0. Good drainage is also essential and surface water should
be quickly removed during the plants’ first growing season.
Weeding the area before planting is vital. Any weeds stuck in an
asparagus plot will be enmeshed in their densely woven roots. In
order to remove the weed, you’ll have to remove the entire
asparagus plant as well.
The most adaptable kind of asparagus is the Jersey Giant. It can
thrive in all sorts of soils and produces medium sized spears.
The Millennium is another good choice. This hybrid produces a high
yield harvest after its’ fourth season. Other types include
the hardy Mary Washington and Viking. You can grow your asparagus
from seed or from the root tops known as crowns. Most gardeners
prefer growing from crowns because they can withstand air exposure.
Buy crowns that are firm and fresh. By pass any withered or mushy
ones since these are probably dying or old. Plant your crowns in
the early spring, either in May or June (depending on where you
live and how warm the climate is)and before any growth appears
from the crown. Dig holes about 6 inches deep. Place a small mound
of earth in the hole, then set your asparagus on the mound. Make
sure its’ roots are hanging down and evenly spread out in
the hole. Now cover the crown with two inches of topsoil. As the
shoots elongate add more and more soil until the hole is completely.
The crowns roots(or tops) should be 4 to 5 inches below the dirt’s
surface. Your planting rows should be a good 2 ½ to 3 feet
apart with an in row spacing of 15 to 18 inches.
Asparagus like damp surroundings so keep their surrounding soil
well moistened. They require one inch of water weekly between the
months of May and October. Weed control is needed in order to eliminate
any competition to developing crowns. When your asparagus reach
their second spring and subsequent years afterwards, till a mixture
of the previous years topsoil and manure into the dirt. Do not
fertilize during your plants’ first year. You can start when
they reach their second season. Use a commercial fertilizer with
a nitrogen percentage in the mid thirties (every fertilizer is
tagged with this code 00-00-00. Look for the first two numbers
to be anywhere from 34 to 37). For more efficiency, dig a shallow
2 inches deep and 6 inches wide trench to the side of your asparagus
rows. Now apply your commercial fertilizer at a rate of 1 lb to
every 100 ft of row. Cover the trench with soil and apply water.
You can also pour the fertilizer and water into the trench together.
Shallow tilling is then required to prevent soil compaction as
well as weed control.
Luckily asparagus does not have any pest problems. There have
been some reported cases of a condition known as asparagus rust.
This is a fungus that causes plant tissue to break down and the
stalks to prematurely lose foliage. Rust afflicted plants are more
susceptible to other attacks from similar soil pathogens. Control
can be achieved with the application of such preventatives as Polyram
or Zinab. The Mary Washington and Viking varieties do not suffer
with this as other asparagus do.
You can harvest your asparagus once it reaches its’ third
season (keep in mind this is only allowed if you planted it when
its’ crowns were already two years old). Do not harvest before
their third year. This will cause stress which will weaken the
plants. Asparagus can be harvested for a two week period only after
three years. During the fourth and subsequent seasons you can have
a full cutting season lasting four to six weeks. Remember don’t
continue cutting well established or mature stalks after June in
any year. The reason being is during the cutting season the plant
draws on its’ food reserves stored in its’ roots from
the previous growing season. The top growth must be allowed to
develop after July 1st in order to replace the nutrients stored
in the asparagus’ fleshy roots. Also excess harvesting during
any year of your asparagus’ life will put additional stress
on the plants. It may also result in a smaller crop the next harvesting
season.
Most cutting seasons for asparagus fall between the first and
fifteenth of May (however this may vary depending on growth conditions).
You can harvest every other day although some asparagus can be
cut on a daily basis. The asparagus shoots should be cut when they
reach a height of approximately six inches. Cut them just below
ground level. Be careful to not damage any new shoots that are
still underground. Asparagus growth takes place near the tip of
the shoot. If you injure this tip, it will result in the stalk
not growing. Cutting is best done with a knife being pushed into
the ground. Now sever the stalk one inch below the soil's surface
Keep cut asparagus in a moist, cold atmosphere( the veggie bin
in your fridge is about the best place for them).
Winterizing your asparagus is another important factor to having
healthy stalks come the next spring. Water them until late fall.
The top growth can be left standing over the winter time. This
will act as a snow trap and help replenish moisture reserves left
in the soil. Also apply four inches of mulch for extra protection.
Asparagus is the perfect addition to any garden. It complements
not only the landscape but also the table with its fresh bounty.
Grow it for it’s great looks and tastes. You'll be pleased
at this wonderful harvest.
