|Ragwed (Ambrosia artemisiifolia L.)
The Ambrosia grows in sunny, dry, often poor and where there is no competition with other plant species. To prevent its establishment, it is sufficient to limit the bare soil, by taking a seeding of plants adapted to site conditions and promoting effect by fertilization.Control of Ambrosia will not totally eliminate the problem but will reduce the rate of pollen in the air and thus help a large number of people inconvenienced by this allergy season.
Symptoms – Recognize ragweed and how to eliminate
Stuffy nose, watery eyes and itchy, the month of August to first frost, ragweed is still claiming victims. So without further ado, let’s learn to identify this weed which bears the Latin name of Ambrosia artemisiifolia. Once unmasked to fight against this problem, simply enforce the uprooting or cutting short just before flowering. THERE is no risk of allergic reaction to touch.
The appearance of ragweed
What is it like this annual plant, responsible for the uncomfortable hay fever? She looks rather harmless and resembles almost any weed. So its asset: knowledge go unnoticed!
The ragweed reaches an average height of 70 cm. The stem, covered with hair, is topped with sheets of grayish green, thin and tightly cropped. They are opposed to the base and alternate at the top. During the months of June and July, the plant is covered with tiny green flowers shaped ear grouped at ends of stems. In August, flowering bursts to let fly into the air billions of pollen grains. And now, the damage is done!
To eliminate ragweed, it is still necessary to know where she is housed. The reaction promotes coexistence and flourished in colonies, encouraged by the rays of the sun.
The ragweed seems to have a penchant for right-of railroads, edges of sidewalks, construction sites, poorly maintained land, a piece of bare earth where calcium has burned the grass in a corner of the garden where the soil has been disturbed. It grows as … a weed!
Symptoms rather unpleasant
Casually, the ragweed causes great discomfort to more than 17.5% of our population. Its pollen causes severe unlucky in some reaction:
- Irritation of the nose
- Tingling of the throat
- Repeated sneezing
- Eyes swollen and teary
- Sinus congestion
- Hoarse cough up some chronic asthma
Health problems, social costs engendered by runaway medical costs and absenteeism at work, these are some of the consequences of this phenomenon that deserves our attention. A radical solution is needed: stop the problem at source by getting rid of the guilty!
Not to be confused with poison ivy
Poison ivy tends to grow near forested areas. This plant bears trifoliate leaves and hard fruit ranging in color from yellow to dull white. These leaves are almost smooth, glossy and sometimes alternate on a woody stem. His contact with the skin causes itchy skin immediately.
Ragweed, meanwhile, presents no danger to the touch and can be pulled at any time without consequence. And when we learn that the survivability of its seeds in the soil is more than 40 years, we realize the importance of taking all necessary means to make it disappear immediately spotted.

Dealing with it … before August!
How to get rid of this plant detestable? The simplest is to snatch it. It’s easy to do since it has a poorly developed root system. But beware! It is essential to perform the operation in June or July at the latest, that is to say, before flowering.
Regularly maintain his lawn. Mainly mowing evenly along the ground making sure to line the exposed corners, are all ways to prevent the emergence of this weed.
While grubbing remains the means of destruction over the practice, one can, in the case of land covered with grass, ragweed, shave regularly ground undesirables. In this way, we prevent them from unleashing their flowering so devastating. However, if one can not overcome, the services of professionals will undoubtedly save an infested field.
