Combating sour clover is definitely one of the unpopular tasks in the garden. Unfortunately, sour clover, also called horn-clover, is one of the most persistent types of weed and also spreads very quickly. The annoying clover is particularly often found in pavement joints. But it doesn't stop at lawns and beds. Climate change favors the spread of sour clover, as it grows preferentially in hot and dry places. You can see this from the reddish brown leaves that mix between the green ones. When the clover blossoms, you can see its yellow flowers. Because of its extraordinary way of reproduction, the sorrel is also called spring clover in Germany: when the fruit capsule pops up, it throws its ripe seed several meters away. So it can spread quickly and widely. But even though the sorrel is so stubborn, there are still a few tricks to successfully fight it in the garden.

How can you fight clover on paved areas?

The sour clover came to us from the Mediterranean and loves warmth and dryness. That is why he finds an optimal living space in pavement joints. You can remove the clover with a joint scraper, but in the long run it will be quite tedious. A weed burner is quicker and more pleasant. Hold the gas flame on the plants for a second or two. And although it doesn't look like it at first, the flaming destroys the cell structure of the sour clover. He dies above ground within the next few days. The disadvantage of this method: The process has to be repeated several times a year because the roots are not completely destroyed by the heat.

How can you fight sorrel in the bed?

If your bed gets a lot of sun and you already have problems with clover in your garden, it will probably spread there as well. Because it is particularly difficult to fight, you should act immediately when you discover it. Perhaps you are lucky and he has neither blossomed nor spread over his seeds. Ideally, you can easily pluck the unwanted plants with their roots out of the earth. In loamy soil, however, the root is usually so firmly anchored that it tears off at ground level. In this case, you have to remove the sour clover with a sharp pick.

Often the clover forms individual closed areas. Here you can loosen the soil piece by piece with a small hand fork and tear out the plants together with their roots. You should then immediately plant perennials and ground cover on the open area. A new shoot can be prevented with additional bark mulch (about five centimeters). If a bed is heavily infested with clover, you have to remove and replace the soil - tedious but effective.

How do you fight sour clover in the lawn?

Sour clover likes to spread out in the lawn and ruin the green area. If weeds are found, it is often recommended to limescale the lawn. But the sorrel wouldn't be such a nuisance if it bothered it - it grows easily on calcareous soils.

It is better to keep your lawn grass as healthy and vital as possible. Then clover has less chances to settle. To do this, it is important to optimize the conditions on site. First of all, you should measure the pH of the soil. In the best case, it is between 5.5 and 6.6. If necessary, the pH can be adjusted again with garden lime. After that, your lawn must be supplied with plenty of nutrients. After 14 days, you can mow it deeply, scarify it and, if necessary, sow it again. Where the sorrel was particularly widespread, it is worth peeling the turf flat after scarifying and applying new topsoil. Finally, the lawn should be watered again so that the grasses form a closed scar again. The sorrel does not like damp soils and does not come back so quickly.

Use of herbicides

Chemical herbicides are often suggested when you are looking for information on controlling sorrel. Although these are approved for the home garden, we strongly advise against their use. The use of chemicals in the garden should always be avoided. This is because they attack not only the sour clover, but also the surrounding plants. Important: The use of herbicides is generally prohibited on paved areas! Recommended alternatives from specialist retailers would be organic products based on acetic acid or pelargonic acid. However, these can only burn the above-ground part of the sour clover - the root and any seeds present in the soil remain intact. After a while you have the annoying clover back in the garden.

Garden tip: Check new plants for sour clover

Many garden owners wonder how weeds actually get into their garden. The sad answer: We usually bring the robust wild herb home with us. The main cause of the spread of sorrel is namely the purchase and insertion of new plants, in the soil of which weed seeds are already found. Our tip therefore: Examine the plants that you want to buy carefully and check regularly at the beginning whether sour clover is showing in its environment. If you spot it in time and immediately remove it along with its roots, you can prevent it from spreading. To ensure that there are no more seeds in the soil, you can also remove the upper layer of soil and dispose of it in household waste, not on the compost.
