Giant Bear Claw is highly toxic
Fight Poisonous Giant Bear Claw successfully
The giant bear claw has become a real plague: Once imported as an ornamental plant to Europe, the aggressive neophyte now displaces native plants and is also extremely dangerous due to its toxicity: even a touch can cause severe burns from the fine nettle hairs. Therefore, it is immensely important to destroy the plant immediately as soon as it appears somewhere.
No fight without protective clothing!
However, before you get to work, you should first wear protective clothing to protect the eyes, skin and mucous membranes from the nettle hair and from the plant juices. It is important here
Furthermore, all measures should take place on a day with a hidden sky: Bark claw injuries occur mainly under the influence of sunlight.
Fight Giant Bear Claw - Methods
The giant-bear claw can be effectively controlled by mechanical methods, whereas the use of herbicides and other chemical substances is usually not allowed - especially in the recreational area and in the vicinity of water!
Timely removal of flowers / seeds
The giant umbels of the Giant Bear Claw produce up to 50,000 seeds, which are widely distributed by wind, water, animals or vehicles. For this reason, the flowers should not even reach the stage of seed formation. So please separate the flower umbels by June at the latest.
Excavate with rootstock
But it is better and more effective to dig out the whole plant right away. It was with a sharp spade dug at least 15 inches deep into the ground and in addition to the above-ground parts of plants and the not a beet not dissimilar rootstock - vegetation cone called - separated or completely excavated. Subsequently, the Giant Bear Claw can not drive out due to non-existing root. If you want to be on the safe side, remove the soil layer, dispose of it and bring new soil.
Mowing / milling
However, the excavation of the plant only makes sense for individual specimens. Sometimes, however, larger areas are affected, which then regularly mowed close to the ground and as far as possible also milled up to 15 centimeters deep. Start in May and repeat the procedure every ten days - all summer long. If available, feed sheep or goats. The animals do not mind the poisonous plant and they eat it in time. On grazed areas, the Giant Bear Claw is therefore almost never to be found.
Safe disposal of plant residues
To safely dispose of the plant remains, you would have to burn them. The Giant Bear Claw is not on the compost, not in the bio-garbage and actually has nothing to do in the residual waste.
Tips
Many people breathe the affected areas with hot water. In fact, this thermal method is effective because roots and seeds are killed by the heat. However, this also applies to all other plants in the area concerned, so it would be better to use a different method.
