Ternitzer environmental adviser warns: "Danger for imported plants"

Plants from other parts of the world are imported for the holidays. Some of our plants feel so good at home that they can spread quickly, move native species and also pose problems for humans.

DISTRICT NUNKIRCHEN. One of these dubious plants is the "Ambroise" or "Ambroisie" called in English "Ambroisie". Pollen or skin contact can cause severe allergies in some people. The flowering period is from August to September, with each plant producing about 3,000 seeds. The plant must be removed in time and eliminated. "Torn plants should not be composted because the seeds are very heat-resistant and tend to accumulate stocks at least twice a year," says environmental advisor Daniela Mohr.

Chemistry in the soil

The tree of the gods is another invasive plant. It penetrates, as well as the introduced Robinia (Scheinacazie), into natural habitats and displaces populations of natural trees by emitting chemical substances to the soil. The sap of the tree is toxic and can cause skin irritation. Pollen can cause allergic reactions, especially during the flowering period. Be careful when slaughtering: this almost always causes rashes and Wurzelausläufer, which then form dense stocks. Years of follow-up or post-cleaning inspections are then inevitable.

Common and known: the giant bear claw

Sheep hog (Hercules shrub) is also extremely problematic because plant juice combined with the sun can cause severe skin damage. The perennial displaces the native vegetation by its large mass of leaves. Small occurrences and individual plants should be removed immediately. Cutting the rhizome to a depth of 10 to 15 cm prevents re-emergence.

Take protective measures

For all measurements, wear gloves, goggles and a dust mask to avoid allergic reactions. In contact with vegetable juice: rinse immediately with soap and water and avoid the sun for 2 days. Nature in the Garden recommends: Do not use invasive plants considered in your garden. If these plants are already present in the garden, it is necessary at least to prevent their propagation in the nature. For some plants, even removing them from the garden is recommended to prevent them from spreading through the fence of the garden.

To use with caution

Vinegar (may cause irritation of the skin and eyes)
Vertiginous or Indian balm
Knotty of Japan,
Canadian or common seaweed
Late Canadian goldrod
Tomatoes from America and Asia, etc.
