Japanese knotweed can be difficult to remove.It can grow to heights of 7 feet, and the roots can be twice that deep.If you want to eradicate Japanese knotweed from your lawn or garden, you should use more than one approach.With a little time, effort, and patience, you can get rid of Japanese knotweed.
Step 1: Remove the canes.
Japanese knotweed won't grow from cut canes, so it's important to trim down as many as you can.Cut the canes as close to the ground as possible, then remove the cut pieces from your lawn or garden.
Step 2: Glyphosate can be applied.
Glyphosate can help you get rid of Japanese knotweed.It will kill almost any vegetation it touches, so make sure to only apply it to the weeds.After cutting down the canes, spray the weedkiller on the plants.If you can't spray weedkiller for fear of ruining other plants, paint the individual canes and leaves with a glyphosate gel.The World Health Organization considersGlyphosate to be a probable human carcinogen.It's not allowed in some states and countries.If handling this chemical, please check your local laws.
Step 3: Wait 7 days before using weedkiller.
Don't disturb the plants for at least 7 days after applyingGlyphosate.The time given to the herbicide to penetrate the root zone is given by this.You should not cut the canes or mow the plant for a week.Take care to dig out the deep roots with a pitchfork after removing the dead knotweed.
Step 4: The plants should be Mowed down weekly.
If you keep cutting the aboveground parts of Japanese knotweed, the plant will die.Each week, mow the plants down as short as possible to help kill them off.
Step 5: Glyphosate should be applied several times.
Glyphosate won't eradicate the Japanese knotweed problem.It is recommended that you apply the weedkiller twice a year in the late spring and early summer.
Step 6: If all else fails, contact a professional.
If your attempts to eradicate Japanese knotweed fail, don't get discouraged.If you want to get an estimate for the removal of this stubborn weed, you should do an internet search for companies that specialize in it.Many companies guarantee their work, making it a worthwhile expense, even though you will have to shell out some money.
Step 7: There are regulations regarding Japanese knotweed in your area.
The United Kingdom requires you to dispose of Japanese knotweed at a licensed landfill site because it is classified as controlled waste by the 1990 Environmental Protection Act.Japanese knotweed disposal rules for the region where you live can be found on the internet.
Step 8: The knotweed needs to be gathered for proper disposal.
Japanese knotweed can be easily transported if you fill trash bags with it.Burning the weed will reduce the volume you need to dispose of.Cut canes of Japanese knotweed for a week or so, then burn them in a fire pit.After the waste has cooled, put it into containers for transportation.Practice fire safety and keep plenty of water nearby to put out the fire.Follow local fire laws before burning yard waste.Burning is not allowed in some areas.
Step 9: To get it to a licensed landfill site, arrange for a registered carrier.
If you live in a place that forbids you from tossing this weed in the compost or trash bin, you will need to arrange for a registered carrier to take the Japanese knotweed to a licensed landfill site.The rhizomes must not spread to the ground and take root if the registered carrier's vehicle is not cleaned.You can use the internet to find a licensed landfill site near you.
Step 10: If allowed, throw the knotweed in the trash.
Japanese knotweed can be put in the trash if there are no rules about how to dispose of it.The knotweed will grow and spread if the dead plants are used for compost.
