Flaming weeds offers many advantages: you can remove the plants quickly, without chemicals and, above all, effortlessly. Especially for people with back problems, the method is perhaps the best choice, because you do not have to bend.

Even more so – when during the garden season not only flowers and perennials bloom, and also weeds spread in the joints between the paving stones, then quick action is required.

By law, the use of weed burners is permitted. To be on the safe side, however, you should ask the local authorities when you are allowed to use the devices and what protective measures need to be taken.

How do I burn weeds properly?

There are two types of weed burners. The gas burners produce flames that heat the weeds around 800° C on average. The electric ones, on the other hand, do not produce a direct flame, but heated jets of air. This causes above-ground plant parts to die after a few days. The weeds then look wilted, not burned. Both the gas burners and the electric devices score points for being very easy to use.  Their effectiveness can vary greatly depending on the weather and the type of weed. The weeds can be removed faster and better during prolonged dry periods. So choose a hot, sunny week to treat the patio or garden path.

To remove weeds safely , you should strictly follow the manufacturer’s instructions regarding operation. As long as nothing else is specified:

  1. Sweep the work area, remove grass clippings, fallen leaves or flowers.
  2. Choose a sunny, windless day and start work early in the morning.
  3. Be patient and hold the flame on each plant for a few seconds.
  4. Especially in late summer, there is a risk that new weeds will grow quickly after flaming. This is because most plants go to seed in August. Therefore, several treatments are necessary until you permanently get rid of the plant.

In most cases, treated plants die after several days and never grow again. However, there are exceptions. If it rained heavily the day before, the weeds will have soaked up and be less susceptible to heat rays. The above-ground parts of the plant will die, but the plants may resprout after a few days.

Flame weeds in joints: How long does it last?

Under optimal conditions, that is, if you remove the young plants in the spring and then treat the paved area every 2-3 months, you can permanently remove the weeds. However, if you remove the pavers and joints for the first time in the fall, then patience is required. However, if you treat the joints after each sprouting in September, you will finally get rid of the plant next year.

If you want to kill weeds in the lawn, then you can also use natural weed killers.
