Bear grass, also known as bear bulb, is an intense weed that can plague many lawns. Bear grass has a very strong root system and develops into a "tuber" form (hence the name bear bulb). The most complete way to get rid of bear grass on the lawn is to remove the weeds by hand. You can also try using chemical herbicides or sprinkling sugar on the grass as an organic herbicide instead of chemicals.

Steps

Method 1 of 4: Identify bear grass

1. 

   Look for clumps of grass that look strange. Bear grass is usually taller and paler than the rest of the lawn. Because bear grass looks similar to other grasses, it can be difficult to spot small patches of grass unless you look closely.

2. 

   
   
   Examine the leaves of the grass. Kneel on the ground to observe the shape and thickness of the leaves growing in strange grass. Bear grass has thick and hard leaves growing from the stem in sets of 3 leaves. Most grasses have two leaves that grow from one stem.

3. 

   Observe the grass. Break off a branch of grass that is suspected of being a bear and watch for the broken head. Bear grass stems have a triangular cross-section and a solid core, while most other grasses have a round stem. Many common grasses also have hollow cores instead of solid cores.

4. 

   
   
   Carefully dig to the roots of the bear grass. If you suspect that a bear grass is based on the shape of the upper part of the plant, you can also proceed with eradication immediately, or dig to the base of the grass to be sure before taking any action. Use a garden spade carefully dig beside the grass and observe the tubers at the roots. You may have to dig up to 30-45 cm deep. advertisement

Method 2 of 4: Manually remove the grass

1. 

   
   
   Wear gardening gloves. This method requires a little digging of the ground, and gardening gloves will help prevent dirt on your skin and under your nails.

2. 

   Use a spade to dig straight into the ground beside the grass. Dig as deep as possible. The root system of bear grass can grow through the soil about 30-46 cm deep.

3. 

   Gently uproot the bear grass roots from the ground. It is important to be gentle with your hands to reduce the number of broken roots as well as the number of broken root pieces.

4. 

   Dig up scattered grass roots. If the roots are left, there is a risk that the bear grass will regrow.

5. 

   Place the grass in the trash bag with the soil dug up. Throw away the grass in the trash bag. Do not throw the grass in a pile or put it in the compost pile, as this may spread the grass to other areas of the lawn. advertisement

Method 3 of 4: Use sugar

1. 

   Use this method in the spring. This works best if done at the beginning of the growing season, when the bear grass has just sprouted and is just starting to sprout.

2. 

   Use a hose to water the lawn. You do not need to water it, but it should be so that the lawn is evenly moist and reaches the ground.

3. 

   Spread the path onto the lawn in straight lines. Walk back and forth on the lawn in straight lines and evenly spaced, sprinkle sugar through the sieve, repeatedly shaking the sieve handle so that the sugar drops to the grass evenly.
   • This is not just folk therapy. Sugar actually "eats" bear grass, and at the same time nourishes beneficial microorganisms for the lawn.

4. 

   Use a hose to spray the lawn once in the morning. Do not water it soaked, as this will make the road disappear. You should only mist lightly, water enough so that the leaves are damp and help the sugar soak into the ground to penetrate the roots.

5. 

   Repeat this process at least twice in the spring. Bear grass may not be completely dead after the first treatment, but after two attempts they will be completely destroyed. advertisement

Method 4 of 4: Chemical control of bear grass

1. 

   Use the herbicide before the bear grass grows five real leaves. The leaves of the bear have too many obstacles to prevent insecticides from penetrating the "bulbs" and roots. Herbicides are most effective if used early in the season, when bear grass is still young and has few leaves.

2. 

   Choose the right herbicide. Products containing MSMA or a chemical called bentazon are most effective. Bear grass is a common problem, so herbicides are often labeled "bear herbicides."

3. 

   Wait for bear grass to grow for a few days before using the medicine. Herbicides are most effective when grass is thriving, and the effect is likely to be worse if applied immediately after mowing. Wait two or three days after mowing the lawn before using the herbicides.

4. 

   Spray the herbicide while the soil is dry. Wait a few days after the last watering before spraying. Do not spray pesticides if there is a chance of rain within 4 hours after spraying or if heavy rain may be expected on the next day, as the chemicals will be washed away by the water and will not have the opportunity to work.

5. 

   Read the instructions on the label to determine the correct dosage to use. MSMA herbicides are usually diluted and sprayed over entire lawns. For example, the label may instruct you to mix 45 ml of chemicals with 20 liters of water to treat 93 square meters of lawns.

6. 

   Repeat this method more than once during the growing season. For tropical grasses, you may only need to spray twice, but cold grass may need to be sprayed 4-8 times to completely kill it. advertisement

Advice

• Determine if beargrass grows in damp soil. Usually, bear grass grows due to poor drainage. If you find beargrass grows in moist soil, you can reduce grass growth by drying the grass and improving drainage in the soil. This may not be enough to eradicate this persistent weed as it can survive dry conditions, but it can reduce bear grass populations.
• Do not try to put garden mulch on bear grass. This herb has a very strong vitality and will usually grow through mulch, cloth, or even plastic.
• Never plow the soil to try to get rid of bear grass. This will only scatter their "bulbs" around and can actually make the situation worse.

Warning

• Keep children and pets away from the grass for 24-72 hours after spraying the herbicide. Many herbicides cause poisoning when swallowed.
• Note that widespread herbicides, especially those containing MSMA, can discolor grass when applied regularly.
