The greed (Aegopodium podagraria) is next to the field horsetail, the field winds and couch grass to the most persistent weeds in the garden. Especially in permanent plantations such as perennial flowerbeds, it is very difficult to combat, as it is both self-sowing and spreading through subterranean rhizomes.
Native is the greed in Europe and Asia. Its natural habitat is nutrient- and humus-rich soil in the light shade of woody plants, where it conquers larger areas with its underground creeping rhizomes. He needs a uniform water supply. Including the white, umbelliferous inflorescences, it can reach stature heights of up to 100 centimeters, but its foliage carpet is usually no higher than 30 centimeters.
Chop off Giersch regularly
Flowering greed (Aegopodium podagraria)
It is very important that you fight every little yaw colony in the spring, as soon as the first tender leaves show, consistently. If the plants are cut off several times a year with the hoe at ground level, they are gradually weakened and the carpet becomes noticeably more greasy. Nevertheless, this method is tedious and tedious, because even after more than a year, the Giersch still has enough power to exorcise in places.
Fight rhizomes with the grave fork
When digging, the root network should be completely removed to prevent further spread of the yaw
On humus-rich, not too heavy soils, clearing the dense root system is the more efficient method: work the soil piece by piece with the grave fork and thoroughly dilate the rhizome mesh. It is important that no remnants of the ivory-colored crawlers remain in the soil, because new plants are created from them. And: Do not dig up a soil overgrown with greed, because that will not solve the problem. Although the newly planted bed looks temporarily good again, the rhizomes are stimulated by the parting to grow and the plant conquers the lost territory very quickly back.
It is important that you do not simply dispose of the yolk leaves and rhizomes on the compost, because the danger is great that they will simply continue to grow there. Therefore, allow the plant remains to dry in the sun for several days. Alternatively, you can make a nutrient-rich slurry from which you can fertilize your tomatoes and other plants, for example.
Suffocate greed with cardboard or fleece
On unplanted areas or under larger trees you can fight the yaw relatively easily by mulching the entire floor with a layer of thick cardboard and then about ten centimeters thick with chopped bark. After two years at the latest, when the cardboard is completely rotted, the rhizomes have died.
However, the seeds remain germinable for a long time, so you must continue to keep a watchful eye on the surface. As a permanent bed cover we recommend a weed fleece made of plastic, which of course should also be laminated with bark mulch. You can plant such a bedding anyway: just cut slits in the fleece and put in these places perennials or roses.
Potatoes as a weed killer
Experienced gardeners swear by potatoes as efficient weed suppressants: The plants shade the soil with their dense foliage and at the same time dispute the greed for water and nutrients. In particular, before the installation of a new garden on a Neubaugrundstück the one-year potato culture is recommended because it loosens the soil in addition to the weed suppression.
By the way: There is also a decorative form of variegated leaves from the Giersch. The variety 'Variegata' is occasionally planted as a ground cover among shrubs, for example. Although it is decorative, but not as vigorous as the wild form. Therefore, it covers the soil well only under optimal growing conditions and suppresses other weed species.

Herbicides as a last resort
Only if nothing else helps, you should also think about the use of herbicides in massive yaw problems. For a long time there were no sufficiently effective resources available for the home and garden. In the meantime, however, there is an environmentally friendly preparation on the market called "Finalsan GierschFrei", which can also effectively combat problem weeds such as greed and horsetail. According to the manufacturer, two treatments are required at intervals of about two to three weeks.
However, it is only sensible to use herbicides under woody plants.In perennial beds or mixed plantings, no comprehensive treatment of the Giersch carpet is possible because the herbicide also damages all other plants. Therefore, in Staudenbeeten that are heavily interspersed by Giersch, usually only the complete new plant. In autumn or spring you should remove all the perennials, divide the rhizomes and carefully pull out all the Giersch rhizomes. Then you clear the bed from the weeds and finally put the shrubs back into the ground.

The snow-white blossom crowns the greed from May to August
Before the weed became a weed in the local ornamental gardens, it was cultivated for many centuries as one of the most famous wild vegetables and medicinal herbs. Giersch contains vitamin C, as well as provitamin A, proteins, essential oils and various minerals. The taste of the Giersch resembles that of the celery, the parsley or the carrot herb and is not only blanchiert but also raw as salad or Pesto edible. If you want to make yuck like spinach, you should harvest a sufficient amount, because it collapses in hot steam. Even soups, casseroles or vegetable dishes can be refined with Giersch. Harvest Giersch to eat in early spring from the end of March and use only the young, bright leaves without stem.
