Green asparagus

The Content Of The Article:


Green asparagus (Asparagus officinalis) is a member of the lily family (Liliaceae) and is native to the Mediterranean and Western Asia. Already with the ancient Egyptians and Greeks asparagus was used and cultivated as a medicinal plant and delicacy. Many hobby gardeners believe that green asparagus is bleached asparagus grown without earthwall. However, this is only partly true: Although bleaching asparagus turns green when you allow it some sunlight, but it also assumes a purple to brownish hue, due to the natural colorant anthocyanin. Therefore, it has been early adopted to breed anthocyanarm and -free, grass green green asparagus varieties. Many come from the US, where green asparagus is much more popular than its colorless cousin. Because its varieties are considered more modest, taste savory and contain more vitamin A, C and carotenoids than white asparagus. Basically, bleaching asparagus is always cultivated on dams, green and purple varieties are grown in flat beds.

Appearance and growth

Green asparagus has a vigorous rootstock that consists of fleshy storage and fine suction roots and grows forward in one direction. Starting from April, finger-thick, fleshy shoots, which are white below the ground, drift above the earth, first blue-red, then green. As vegetables, the young shoots appearing in early summer are used. If you do not separate them, then up to 150 centimeters high, thin, branched stems with tiny leaves develop.

Young shoots of green asparagus

Only the young shoots of the green asparagus are harvested

Green asparagus is one of the dioecious plants, like pale asparagus. That is, there are both male and female plants, the pollen of the male plants is flown from insects to the female plants. Since female plants produce fewer rods and have a shorter lifespan, only pure male varieties are usually cultivated.

Location and ground

Green asparagus can be cultivated on the same bed for up to 15 years if properly cared for. It thrives unlike pale asparagus on any soil and does not need to be accumulated. When preparing the bed, you can save a lot of work by sowing a green manure last year. Deeply rooted soybeans, lupines or bush beans leave behind a well-aerated, humus-rich and loose soil in which the green asparagus can quickly gain a foothold.

Asparagus seedlings

Asparagus plants have Saugwurzeln and meaty storage roots. The latter can be over 50 centimeters long

Crop rotation and mixed culture

When green asparagus a mixed culture is possible with bush beans, carrots, onions and marigolds.


You can theoretically sow green asparagus from March / April in boxes with potting soil or in the greenhouse. For this you bring the seeds at a distance of eight to ten centimeters in one centimeter deep grooves in the row spacing of about 20 centimeters. The following spring, the young plants are then transplanted to the final location.


Put young plants in the ground

You put the asparagus young plants at about 40 centimeters distance on small compost hills

The cultivation of own asparagus plants by sowing is possible, however, by the purchase usually as a rootstock of preferred young plants, the time until the first harvest can be shortened by at least one year. Seedlings of green asparagus are available at asparagus farms on site or by shipping. Eight to ten young plants per asparagus eater should be at least. In late frost or wet and cold weather, you can store the root braids after the purchase in a cool, dark room for about a week.

The best planting season is in the spring from March to April, before the young plants begin to drift. So that the shoots do not dance out of line later, you spread out the spider-like mesh on the loose soil and make sure that the longitudinal oval buds of all seedlings point in the same direction. During the rhizome planting, a 30-centimeter-wide and 25-centimeter-deep trench is lifted in the longitudinal direction of the bed and mixed with five centimeters thick applied frost compost in the graben sole. Then place the root braids 40 centimeters apart and cover at first only five centimeters high.

Plant asparagus

Although early asparagus plants form rods earlier, they are a bit more expensive than rhizomes

Early asparagus plants in the pot are significantly more expensive than root rhizomes, but earlier bring first bars and the trench pulling omitted. They are planted at a distance of 25 to 40 centimeters in a sunny bed of sandy soil. The root ball should sit about three inches below ground level.


A mulch layer keeps the soil moist and suppresses weeds.This is only completely rotted, at least a year old mature compost or composted autumn leaves. The material does not need to be screened, but can then be thinner and more evenly distributed. Keep the green asparagus sufficiently humid, especially during dry periods.
The first fertilizer application is made with organic vegetable fertilizer or vegetable veggie fertilizer. As a rule of thumb, apply a handful of fertilizer to two running meters and score on the surface. Easy sprueing promotes rooting - but not too much, depending on the soil, the soil is still wet enough at planting time anyway. From the second year you fertilize each in March and the end of June and then renews the mulch layer.
The main problem is weedy weed. If root weeds such as couch grass have spread, it usually takes two to three years until the bed is free of weeds if collected consistently. White goosefoot and other seed weeds hardly slow down the growth of asparagus plants - provided they are young and can not be sown.
In the first and second growing year you can use the bed twice and plant salad and kohlrabi between the asparagus rows. Tip: The permanent solution is a bedding arrangement of monthly strawberries. If your green asparagus runs from its third year to top form, you can pick the sweet fruits for dessert at harvest time.

Harvest and recovery

Harvest of green asparagus

The harvest starts with green asparagus in mid-April

In well-developed seedlings may cut a few rods in the second year of cultivation. During the harvest phase from mid-April, all sprouts must be cut continuously as soon as they are 20 to 30 centimeters high. The green shoots are cut off directly above the ground as long as the heads are still closed. This also applies to damaged or pencil-only rods! If you leave them, less or no new shoots will grow. Closing date for green asparagus is already in the second week of June.

Best harvest in the early morning, because then the proportion of flavoring sugars and flavorings is highest. You will stay fresh if you place the asparagus spears in a tall container immediately after harvest and add some ice water. Until preparation, they are stored in the refrigerator at two to five degrees Celsius.
It is best to use the harvested green asparagus fresh. And there are plenty of opportunities for that - not without reason is asparagus one of the most popular delicacies in the spring. You can use the green asparagus stewed, fried or raw in salads. These bars are cooked in a few minutes. Green asparagus grilled or fried tastes particularly delicious. Green asparagus can also be processed largely unpeeled - only the slightly woodier stem base must be peeled occasionally.

Cut the asparagus spears with a sharp knife just above the ground

After the harvest, the asparagus shoots shoot up and develop densely branched stems with filigree foliage. So the plants store reserves in the roots for the sprouting next year. In the middle of the vegetable patch disturb the perennial shrubs, on the garden border in front of a wooden wall or wall, on the other hand, they offer a pretty picture. A cord stretched along the edge prevents the thin shoots, which are up to 1.50 meters high, from falling apart or breaking off.
Make sure you've sprinkled the asparagus bed with cornmeal right after the harvest and possibly renew the mulch layer so that the summer sun does not dry out the soil too much. The withered asparagus shoots are cut in the late autumn a hand's breadth above the ground, roughly chopped and composted. An asparagus bed can be used for up to ten years, only then the yield slowly decreases.

Asparagus perennials

The asparagus shoots grow up to over one meter high perennials. Tip: The asparagus herb looks nice as green in summer bouquets

variety Tips

The variety 'Snow White' is one of the best known German varieties of green asparagus. It has a pure green color, is extremely delicate and aromatic and can be grown on heavier soils as all varieties, as the dam culture is eliminated. The variety 'Primaverde' is very early, productive and also free of anthocyanins. 'Martha Washington' is a standard green asparagus variety in the USA.

Asparagus 'Jacquma Poupré'

Green asparagus 'Amaro Montina'

Deep purple varieties such as 'Jacquma Poupré' (left) are cultivated like green asparagus and can cope well with less good soil. 'Amaro Montina' (right) is a tasty, slightly bitter wild asparagus selection. The plants are highly resistant to asparagus rust

Tips for buying asparagus:

Regardless of whether it's a green or purple variety, freshness is crucial for taste and quality. The interfaces should be wet. With asparagus offered in crates and chip baskets, this can easily be recognized. The heads must be largely closed. Spread the sprout tips, the rods were stung too late and are often lignified in the lower part. The end of the rod must be bright green or violet colored.Green asparagus with bright ends was cut too close to the rhizome. The bars taste bitter!


Asparagus is either propagated via seeds or vegetatively via sticking. For this you should shorten the rhizomes evenly to ten centimeters.

Diseases and pests

Green asparagus is relatively robust in terms of diseases and pests. The asparagus fly (Platyparea poeciloptera) frolics in the crop residues. That's why you should not stand a stump when cutting, but also not cut too deeply. In autumn, the yellowed herb is also cut as deeply as possible. Composting is recommended only if it is previously finely chopped, otherwise the residues are disposed of in the green section. Asparagus chicken (Crioceris asparagi) is easy to pick up. To do this, fill a bucket with water, add a drop of dishwashing detergent and tap the tiny beetles over it. This works great in cooler temperatures, in warm weather, the tiny beetles are very nimble and fall to the ground at the slightest touch.
