Planting asparagus

While the different varieties offer early or late harvests, it is usually in spring that they are best enjoyed. Follow our advice to have a good harvest and avoid disease.

We distinguish 2 types of asparagus, white asparagus and green asparagus. Both are cultivated in the same way.

In the month of February to April, it is important to plant the asparagus in a row and preferably in the direction of the wind.

Asparagus is greedy so a pre-fertilization of the soil is necessary.

  • Prefer them sandy land because they heat up faster
  • Avoid wetlands
  • You will respect a distance between each plant of 50 to 60 cm and 1.5 m between each row.

The asparagus plantation is done thanks to the young tufts coming from the seedling called "claw".

  • The first year, make a trench 2 to 3 cm deep and place the claws at the bottom of your trench,
  • Then cover with a few centimeters of potting soil or good fine soil
  • then fill with soil from the garden.

In sowing, wait the following year to put them in place

Cultivation of asparagus

The cultivation of asparagus is carried out in 2 stages because they cannot be harvested in the first year.

To go faster you can directly buy plants that are already 2 years old.

  • The first year, we cover the claws with 2 to 3 cm of soil,
  • The second year the claws are lightly covered with 15 to 20 cm of soil

Thus, once properly in place, you can harvest your asparagus for almost 15 years.

In regards to watering, asparagus needs water regularly but hate standing water.

Asparagus harvest

Asparagus should be harvested while still tender and cut with an asparagus cutter.

The best period to harvest the asparagus is fromapril to june. The asparagus is harvested with a gouge or a long knife.

  • When the shoot tips the tip of its nose, it indicates it is time to harvest the asparagus (After that, it is best to let the asparagus develop.)
  • Drive the knife as deep as possible to slice the spear and have as much as possible asparagus in good condition.
  • Green asparagus are shallower and a simple knife is enough to harvest them.

Tip: It is best to wait 3 years before starting to harvest asparagus to allow the plant to develop during the first years of its life.

To know about asparagus

This vegetable is particularly rich in vitamin C, but it is best known for its finesse and its subtle and delicious taste.

The ancestor of asparagus that we know today was officinal asparagus.

The taste of asparagus depends mainly on the nature of the soil and its richness in organic matter.

Thus, clay soils will give them a rather bitter taste.

There are several kinds of asparagus:

  • Green asparagus: arguably the most subtle in taste, it does not need to be peeled.
  • White asparagus: quite common, it is larger and can only be eaten after having been peeled.
  • Purple asparagus: relatively rare, it is more like green asparagus.
  • Wild asparagus: fine and delicate, it goes perfectly in salads.

To get the most out of them, eat them as soon as possible after they have been cut, this is the guarantee of a better flavor.
