The Canadian goldenrod is one of the plants, along with the Indian balsam, that have become a real threat to the native flora. In order to prevent further spread of the Canadian goldenrod, permanent control is necessary.
The Canadian goldenrod displaces native plant species
That is why Canadian goldenrod must be fought
The plant is native to North America and was introduced to Central Europe as an ornamental. It can be found in many gardens and is valued for its pretty spikes of yellow flowers, vigorous growth and suppression of other plants.
It is precisely these properties that make the Canadian goldenrod a problem in nature. The ornamental plant also spread in the wild and displaced native plants. The nutritional value of their nectar and pollen is lower than that of native species, causing additional damage to bees and bumblebees.
Methods of controlling Canadian goldenrod
- stop seed development
- Cut plants short regularly
- dig up rhizomes
- Cover surface with foil
The control of Canadian goldenrod is complex and takes several years. The plant reproduces via seeds and underground runners.
First of all, the formation of seeds must be prevented. For this purpose, areas on which Canadian goldenrod grows are mowed in good time. Digging up the rhizomes only makes sense for small stocks.
As a result, regular mowing is urgently needed, as this is the only way to weaken the rhizomes and prevent new runners from forming. Affected areas must be cut at least two to three times a year. The cuttings should be removed to make it easier for native plants to resettle.
Reseed fallow land immediately
Canadian goldenrod is a so-called pioneer plant, which is particularly fond of spreading on fallow land.
One way to prevent this is to work fallow land as soon as possible and sow meadow herbs or other fast-growing native plants. Alternatively, a foil can be applied.
Wear gloves when controlling Canadian goldenrod
Canadian goldenrods trigger contact allergies in sensitive people due to the escaping plant sap. Gloves should therefore always be worn when fighting.
tips
Like all goldenrod species, the Canadian goldenrod is not poisonous. It is even one of the medicinal herbs. Even the Germanic peoples appreciated its healing effects on wounds, rheumatism and gout.
