There seems not one effective ragwort eradication solution. Each one of the technique known has faults. A common method is slashing or cutting yet this is the most unsuccessful method. New plants can thrive out of existing roots and this makes cutting the worst weed eradication method ever for ragwort.
A good way to eliminate ragwort is always to chop off the big roots and the crown. You cannot do it by using your hands for pulling. Also, enormous plants come with large roots which are often well secured to the soil so tugging them may leave a few of the root fragments under the surface. Moreover, if ever you draw the roots, some of the hidden seeds will be exposed to sunlight. Exposure to air and sunlight promotes sprouting of seeds.
Manual removing of flowers works well solely for controlling the spread of seeds. The seeds should be placed into garbage bags and eventually thrown away. Tiny growths of ragwort are easy to remove by using simple tools such as shovels.
Mowing is often not effective simply because ragwort may grow a couple weeks later. What is worse is usually the weeds start to have more crowns and tend to be more tough. This is why mowing or slashing must be supported by herbicide spraying.
One more ragwort control technique is cultivation, but its reliability is only limited in autumn and spring, although cultivation during summer is also done. Nonetheless, cultivation lessens the number of pernicious weeds and prevents growth of new plants. What you have to make sure is step-by-step implementation of cultivation which may include things like introduction of crops that compete against the weeds for nutrients and water. For example, planting of oats enhances pasture and imposes competition with the invasive plants.
However, among the disadvantages of cultivation is greater propensity of soil erosion. Moreover, it doesn’t ensure thorough elimination of ragwort. New plants may appear right after cultivation and they may be eliminated by spot-spraying.
There is absolutely no other successful methods to curb increase of ragwort than continuous elimination. The area should be inspected occasionally to look for new growths. Herbicidal use should be done with extreme caution since most weed killers destroy other plants. Consult a specialist regarding registered chemical products which fight particularly against ragwort. Using the incorrect chemical substances can destroy the atmosphere.
A different way to curb the growth of these types of invasive weeds is through setting up of fences around the affected area. The plants could be kept to fill the place with low chances of invading neighboring premises. As the plants increase in a restricted space, they start competing against each other for water and nutrients.
Elimination of ragwort is just one of the weed control steps applied by property owners and farmers. Some other measures are giant hogweed along with Himalayan balsam control.
