Creeping weeds in the lawn is an absolute nightmare for any amateur gardener. However, if you can correctly determine the weed species, you can fight them. To save yourself a lot of trouble and worry, you should check the lawn as early as spring.

Yellow flowering weeds in the lawn: Identify and destroy dandelions
If you see yellow weeds in your lawn, they are most likely dandelions. This herbaceous plant has ovate, highly lobed leaves and bright yellow flowers , which, by the way, are edible. As with all other weeds, you should act as soon as possible. Preferably as early as spring.
Destroy dandelions: Unlike other grasses, you can’t stop the spread of dandelions by scarifying in the spring. The plant quickly recovers from pruning and forms flowers again. It is better to cut them out. If you find individual plants, then you can infuse them with boiling water. This procedure should be repeated twice a day until the plant withers.
Alternatively, you can make a solution of vinegar and water yourself. It is best to first check with local authorities to see if the use of this home remedy is even allowed. Otherwise you risk fines. If the use is allowed, then you can (but really in very rare exceptional cases) use apple cider vinegar with 15% acidity and mix it with water in a 1 to 1 ratio. Then spray directly on the leaves and aerial parts of the plant. But in no case pour the vinegar solution directly into the soil. If the plant leaves turn yellow-brown, then it is a sure sign that the plant has died. In any case, it is better to use approved means for weed control from the store.
Weed with small yellow flowers: control horned wood sorrel.
Horned wood sorrel is recognizable by its small yellow flowers. These are formed as early as mid to late April. It spreads quickly and only becomes noticeable when it is already too late. So if you recognize individual plants in the lawn, then you can dethatch the lawn, depending on the condition, lime the soil and reseed. Fertilize the lawn abundantly so that it can grow densely. Water the grass extensively to speed up its growth. Wood sorrel can tolerate a lot of moisture poorly. If these measures do not help, you will have to remove the old lawn completely and reseed it.
Determine creeping weeds in the lawn: Field thistle has purple flowers
Field thistle is a perennial plant that spreads very quickly. Therefore, you should fight it in time. The thistle has an erect growth, spiny elliptical leaf edges and pink flowers , which then turn purple. The plants have long root shoots and therefore cannot be easily pricked out.
Destroy creeping thistle: Aerify the lawn. The weed spreads much slower in the loose and airy soil. The second step is to cut the plants off close to the ground. You should dispose of the plant debris immediately to prevent it from spreading in the garden. Repeat the process and cut the above-ground plant parts close to the ground another 3 – 4 times to weaken the weeds. Then you can carefully dig up the roots.
Identify creeping weeds in the lawn: Here’s how you can eradicate mugwort.
Mugwort-leaved bunchgrass is a plant with hairy stems and pinnately lobed leaves. The weed forms its flowers in summer. They contain pollen that can cause allergies. In this country, the creeping weed is known mainly as a field weed, but it is now spreading into small gardens, especially in the southern parts of the country.
Pulling out the plants proves to be an effective and environmentally friendly measure. To protect yourself from the pollen and prevent allergies, you should wear the appropriate protective clothing when doing so. This includes old gloves (which should be disposed of afterwards) and a dust mask.
Millet in the lawn: The blood millet
Blood millet is an annual grass that reproduces by seed. These can remain in the soil for up to three years before germinating. So even if you haven’t had a weed in your lawn in recent years, you should check it in the spring to be on the safe side. You can identify it by its bright green grass blades and typical growth (which resembles a crab). The weed prefers soil with a high sand content.
Destroy leaf millet: Be sure to scarify the lawn. Flower millet can recover well after being cut back, so if you find large plants in the lawn, be sure to remove them.
Re-seed the lawn as needed to prevent weeds from growing. Then fertilize the grass regularly, watering during prolonged dry periods. Possibly, liming could have a positive effect. As a rule, if the lawn is dense enough, then it will also inhibit the growth of weeds.
In the worst case scenario, you can use chemical pre-emergent and post-emergent control agents from your local dealer. However, get thorough advice on this in the garden center.
