Asparagus - one plug


Botanical name:

Asparagus officinalis

Asparagus is a perennial ... You deserve it!

We know asparagus well, at least on our plates. Asparagus is a vegetable that takes time (and self-sacrifice), without being too difficult, because between the first stage of sowing and the first harvest of asparagus, there will generally be 2 years and 3 springs. . Once launched, the cultivated claws will yield the "fruits" of your labor every year.

Asparagus is a hardy herbaceous plant, which can reach 1.50 meters in height. It is a crop that will be able to stay in place for a few years because it does not exhaust the soil. according to the literature, we say between 8 and 12 years. It is said that the longevity of an asparagus grove ranges from 8 to 15 years.

Type of plant

Type : Vicaceous, rustic.

Family : Asparagaceae - asparagaceae

Foliage : obsolete

Rooting : rhizome

Origin : center of Europe - it is endemic to some regions of France.

Particularity

• Resistance to cold: - 20 ° C
• Soil: all soils, with a preference for sandy, light and loose soil
• During the first 2 years, it is important to train the stems.

How to sow Asparagus

From March and until June, we prepare the seedlings for the following year, in the nursery:
• Prepare the ground. It should be rich in humus and well loosened.
• Plant a seed every 5 cm and separate the rows by 30 cm.
• Cover the seeds with an inch of potting soil.
• Thin out every 10 cm after the shoots have emerged.
• These plants will grow until the following year to be replanted in March. These are the claws that will be transplanted.
• For maintenance, the hoeing should not be deep so as not to damage the roots.

How to plant the asparagus claws

In the fall, prepare the land:
• Dig trenches about 20 to 30 cm but no more and about 40 cm wide.
• Arrange the earth in an embankment on either side
• Space each trench at least 4 feet - 1.50 meters apart if possible.
• Loosen the bottom of the trench without turning over the earth.
• Add compost and scratch again.

Prepare for planting:
In the following spring, 1st year:
• At the bottom of the trench, make a small butt 10 cm high.
• Plant a stake every 70 cm, on the one hand to identify the claws and on the other hand when the asparagus stalks have grown, it will be necessary to "train" them for the first 2 years because the asparagus stems will be fine and fragile.
• Place the claws near the stakes after cutting the roots that are too long.
• Cover the bottom of the trench so that the stops where the asparagus claws are placed are only covered by a maximum of 3 cm. Do not level the ground. The rest of the “embankments” will be used in a few months.
• Do not hesitate to tutor as soon as the stems appear, without tightening them too much.

In the following spring, 2nd year:
• Level the soil with the soil that remains on the sides after adding compost.
• Hoe and weed regularly to keep the planting area free from weeds or weeds.
• Tie the young fragile stems to the stakes.
• No harvest this year!

The third year is good!
In the spring and the following years:
• Set up a 20 to 30 cm mound of earth, this operation is necessary for the production of white asparagus. (It's not for green asparagus)
• Throughout the season, hoe and weed to aerate the soil.
• Harvest! (from April to June)
• Be careful the first year we only harvest 1 or 2 "spears" so as not to weaken the soil.

From the 4th year, the harvest takes place normally.

Maintenance and asparagus

After harvest:
Lay down a mulch to prevent the sun from drying out the claws during the summer. The stems should always be attached to their stake.

At the end of autumn:
• Cut the yellowed stems and put them in the composting system if they are healthy.
• Flatten the white asparagus cultivation mounds and amend the compost soil on the surface.

Every year, at the beginning of spring:
Redo the mounds for white asparagus and add compost and a natural fertilizer (phosphorus and potash). For example, fish bone meal, or beet stillage ...

Gardening with the moon

• In the third year, the mounding of the spears becomes an increasing and / or decreasing moon.
• The harvest becomes root day

Gardener's Info

Soil type: Lightweight, loose and humus

Exhibition: Sun

Watering: only in case of drought

Harvest period : from April to June, for white asparagus, once the spears protrude from the stems.

In the garden, the asparagus ... and the gardener

• The main pest of asparagus is Beetle. So my offers you a very simple association: add tomato stalks near the asparagus cultivation.
Claw rot: the foliage turns prematurely yellow in season and the roots are covered with purple down. Tear off the affected feet, throw them in the trash, do not burn them.
Rust : the stems become covered with a kind of rust-colored dust. This disease is often spread when the soil remains too wet. As a prevention, spray with Bordeaux mixture. BE CAREFUL of compost: the organic matter used to strengthen the culture must be properly broken down, and finely ground.

The gardener's advice:

• Therefore prefer an ORGANIC (AB) seed
• Also favor the SOC Label (official certification service)
These 2 labels guarantee the varietal identity and the good sanitary condition of your purchases.

Associations in the vegetable garden:

Companioning vegetables in the garden is called companionship, and it is the art of growing vegetables that get along well together. Asparagus is no exception to the rule. Some crops are favorable to it (and vice versa) and conversely other combinations of vegetables are more harmful to it. Please note, these associations are first and foremost a matter of proximity. That is, vegetables that go well together will end up planted in rows or areas of the kitchen garden nearby. Conversely, crops that do not go well together may be found in the vegetable garden during the same period, but they will be greatly removed.

Favorable associations:

• In the vegetable garden, asparagus appreciates being grown near tomato, cucumber, pea and leek plants.

Unfavorable associations:

• On the contrary, with asparagus, it is important to space the rows of beets, garlic and onions.


We recap

• Type of soil: Light, loose, sandy

• Planting: with the Crescent moon in late autumn

• Maintenance: little, in dry weather, weed and water.

• Harvest: waning and waning moon from March to June, once the spears emerge from the earthen ridges.

Herbaceous vegetable plant very rustic, asparagus (Asparagus officinalis) is grown in a vegetable garden for its tender and delicious young shoots: them. These develop from an underground stump: the claw.

Early or late depending on the different varieties, however, it is always in the spring that the asparagus is eaten. It forms a bushy bush with feathery foliage (florists' asparagus) and is covered with tiny yellowish flowers from May to August, followed by red berries, only on the female feet.

The taste of asparagus depends on the nature of the soil and its richness in organic matter. So, clay soils will give a rather bitter taste.

Today China is the world's largest producer of asparagus, Peru is its biggest exporter, and the Germans are †“by far – its biggest consumers.

Asparagus also has many medicinal properties:

  • The phenolic acids it contains play an essential role in the prevention of cardiovascular diseases.
  • The plant improves venous circulation and promotes toxification of the organism, via the lymphatic system.
  • It is also a powerful diuretic thanks to its richness in potassium and asparagine.
  • It participates effectively in the elimination functions of the organism thanks to its fibers.
  • And finally, its particularly low sodium level makes it the ideal vegetable to fight against hypertension.


Planting

  • Carefully prepare the ground intended to accommodate the asparagus, which will remain in place for more than ten years.
  • Loosen the soil deeply over a maximum of 50 cm and enrich with composted manure and / or an organic fertilizer rich in phosphorus and potash.
  • In March, divide the land into parallel strips 40 and 60 cm wide.
  • Dig trenches 15 to 25 cm deep (or 5 to 15 cm for green asparagus) depending on whether your soil is heavy or light.
  • Be sure to plant the claws as soon as possible after obtaining them. Prepare them: the damaged root ends are cut off and sprinkled with crushed charcoal which will allow them to heal better.
  • Place a small stake every meter and plant the claws by correctly spreading the roots at the foot of these stakes. Cover with a maximum of 10 cm of soil. The tutor allows you to locate your plantations: in fact, during the following 2 years, you will not harvest spears and will let the plants develop their vegetation.
  • At the end of winter, make a hill 25 to 30 cm above the white asparagus beds. Instead of the mounds, place a plastic tunnel over the rows of green asparagus. Stimulated by heat, the claws will emit rapidly growing shoots, allowing them to turn green while remaining very tender.

Successful cultivation of asparagus

Successful cultivation of asparagus

Among all the asparagus (Asparagus officinalis L., Liliaceae), we find some more or less late or early, which can allow the harvest to be spread out.
Asparagus is perennial thanks to its underground parts, and tolerates all types of climate: it is a very rustic vegetable plant.

What is called "asparagus claws" is actually the set of roots. It is from these claws that the stems that we know and which are edible are issued: asparagus. But be aware, the real name of "asparagus" is "turion".

In order to obtain a harvest, patience is required. In theory, you have to wait 3 years. The claws sold at the Ferme de Sainte Marthe have been cultivated for 2 years already, which requires you to wait one year before harvest. Then, the harvests are done annually for 10 to 15 years.

Soil and exposure

This is not a myth, asparagus claws particularly like sandy soils, which will heat up quickly. But they can be satisfied with a more classic floor. In any case, avoid cold, wet soil.

Note that asparagus prefers a sunny exposure, even if it adapts to partial shade.

We recommend planting the prongs from February to April. The soil must be properly prepared to ensure the sustainability of the crop.
The ideal is to prepare your soil in autumn. However, it is possible to do this later.

Explanation of the diagram:
1. Dig trenches about 25/30 cm deep, 30 cm wide. Leave the reject soil between the trenches. These trenches will be spaced approximately 1.80 to 2.00 meters apart. Therefore, loosen (without turning over) the bottom of the trench and incorporate compost and bottom fertilizer.
2. When planting the claws, make small ridges of earth about 8 cm high, which you will space 70/80 cm apart. Do not forget to add a tutor who will identify the location but also support growth during the first years. On each of these small butts, place a claw by spreading the roots well. Cover with soil to a thickness of about 6 cm.

Cultivation management
During this first year, the plant will slowly take its ease. From the second year, the ground must be leveled. And then, each year, a stop must be made during the month of March over the entire length of the trench, and to a height of 50 cm.
From October, cut the dry stems above the ground and level the ground.
Annual fertilization will be welcome, although asparagus is not considered an impoverishing plant.
"One hoeing is worth two waterings": an old adage which also applies to asparagus

Harvest
From the third year (and it is important not to harvest before, at the risk of compromising the good development of the plant afterwards), it is possible to harvest 1 or 2 shoots.
It is only from the fourth year that a normal harvest is possible.
The shoots are harvested using a gouge to fetch them delicately and deep in the ground.

Enemies
The main pests of asparagus are flies (seedlings, asparagus and leafminers) and beetles.
Only beetles may require intervention when their number produces a real defoliating effect in late spring and / or summer. If this is the case, the plants should be monitored after their spear production, that is, when the canes are forming, and spray only when the larvae are young. Aphid attacks are rarer, but in the south of France, it is sometimes necessary to intervene at the end of the season.
After planting, the diseases observable on canes and leaves (cladodes) are mainly rust, especially detrimental to young plantings and stemphylliose, responsible for the dieback of asparagus by drying out of the aerial parts. It is then necessary to treat preventively in sensitive regions (south), in stormy periods.
If a treatment is necessary, we will only use products with the mention "authorized in the gardens".


Good 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 doesn't need to be peeled.
  • White asparagus: quite common, it is larger and can only be eaten after being 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.


VI. Best associations

Apart from the first year, when lettuce or green beans can be grown on the side mounds, they take up all the space. Their foliage in fact forms a mass more than a meter high and just as wide. Perfect to house children's games. We should avoid scattering asparagus in the flower beds, even if it seems tempting, because the sight of three large parties often plucked by the beetles is not an enchanting spectacle. If one is looking for a feathery foliage effect, fennel is much better suited.
