Roundweed or sedge is a terrifyingly resistant weed that plagues many lawns. She has strong roots and nodules, and the fruit is a triangular nutlet. The best way to rid your lawn of sedges is by hand weeding, removing the plant and its root. However, you can also resort to chemical herbicides or, as an organic alternative, sprinkle sugar on the grass.

Steps

Method 1 of 4: Recognizing sedges

1. 1 Look for tufts of grass that grow out of place. Sedge usually grows taller and lighter in color than the rest of the grass. Because sedge is similar to other types of grass, small tufts will be difficult to spot unless you specifically look for them.
2. 2 Examine the leaves. Get on your knees and look at the shape and thickness of the leaves that grow from the ground. Sedge leaves are dense and tough, they grow from the stem in three. Most other varieties of grass have only two leaves per stem.
3. 3 Examine the stems. Break the stem of the suspected sedge and examine the broken edge. Sedge has a triangular stem with a solid pith, while most other grasses have round stems. Most common grasses tend to have a hollow core rather than a solid core.
4. 4 Dig carefully to the sedge root. If, based on the appearance of the top of the plant, you decide it is sedge, you can either remove it right away or dig to the root to confirm your suspicions before taking any action. Take a garden trowel and carefully dig a hole near the tuft of grass and look at the root for the presence of walnut fruits. To do this, you will need to dig a hole 30-46 centimeters deep.

Method 2 of 4: Weeding by hand

1. 1 Put on a pair of gardening gloves. This method requires you to dig quite a bit in the ground, and gardening gloves should reduce the amount of dirt on your hands and under your nails.
2. 2 Insert a garden trowel next to the sedge. Dig down as far as possible. The sedge root system can extend to a depth of 30-46 centimeters.
3. 3 Carefully remove the sedge and its roots from the ground. This should be done as carefully as possible in order to reduce the number of broken roots and the number of pieces that these roots can break into.
4. 4 Dig out the remaining roots. If roots remain in the ground, there is a chance that sedge may grow back.
5. 5 Take a trash bag and put the weeds in it, along with the soil you dug with them. Then, throw the weeds into the trash can. Do not throw them into a pit or compost heap, as this may result in spreading them to another area of ​​the lawn.

Method 3 of 4: Applying Sugar

1. 1 Follow this procedure in the spring. This process is most effective at the beginning of the growing season, when sedge is just beginning to germinate and sprout.
2. 2 Hose your lawn. You may not want to water much, but the lawn should be evenly wet right down to the soil.
3. 3 Sprinkle sugar on the lawn in straight lines. Walk back and forth across the lawn at a steady pace. While walking, pour the sugar onto the lawn through a sieve, turning the knob constantly so that the sugar falls on the grass in equal portions.
   • This method is not a common folk remedy. Sugar literally eats up the sedge and at the same time fertilizes microbes that have a positive effect on your lawn.
4. 4 Water the lawn again with the hose. Do not water too much, as this will only wash away the sugar. Water the lawn lightly so that the water will rehydrate the leaves of the grass and the sugar will penetrate the soil and roots.
5. 5 Repeat this process at least twice in the spring. After the first treatment, sedge may not immediately disappear, but after two more procedures, there will be no trace of sedge.

Method 4 of 4: Chemical Control

1. 1 Use herbicides before the sedge has five leaves. Leafy sedge has too many obstacles to keep the herbicide from rolling down to the fruit and root. Herbicides are best used early in the season while the sedge is still young and has few leaves.
2. 2 Choose the right herbicide. Products that contain MSMA or a substance called bentazone are best. Sedge is a common problem, so any weed killer will be labeled as a “sedge killer”.
3. 3 Let the grass grow for a few days before applying the herbicide. The herbicide works best when the weed is growing vigorously, so it will not be as effective if applied immediately after weeding. Wait a few days after your last weeding before treating your lawn with this chemical.
4. 4 Apply the herbicide during the dry period. Wait a few days after watering and do not spray your lawn with herbicide if it is expected to rain in a few hours or if it rains heavily over the next few days. The water will wash away the herbicide and he will not have the opportunity to do his job.
5. 5 Read the instructions on the herbicide bottle to determine how to use it correctly. More often than not, you will first crush MSMA herbicides and then spray them on your lawn. For example, the instructions may say that 45 milliliters of the chemical should be diluted in 20 liters of water in order to treat 92.9 square meters of lawn.
6. 6 Treat the lawn several times during the growing season. The grass for the warm seasons will need to be treated twice, but the grass for the cold seasons will need 4 to 8 treatments before the sedge disappears completely.

Tips

• Determine if sedge grows in wet areas. Quite often sedge appears due to poor drainage of the land. If you find sedge growing in wet areas, you can minimize further growth by drying the grass and finding solutions to improve soil drainage. This may not be enough to kill this resistant weed, as it can grow even in complete drought conditions, but it will at least reduce sedge numbers.
• Never dig in the ground in an attempt to remove sedge. Digging up the ground, you will only spread the "nuts" and instead of doing what is best, the situation can only get worse.
• Do not try to cover the sedge with mulch. This weed is so persistent that it can easily push its way through mulch, pieces of fabric, and even plastic.

Warnings

• Keep children and animals away from the grass for 24-72 hours after applying the herbicide. Most of these chemicals are toxic.
• Beware of the fact that widely used herbicides, especially those containing MSMA, can cause discoloration of the grass if applied frequently.
