As a homeowner, have you ever wondered “how much roundup per gallon of water” you need for your lawn?
Look no further! We’ll go over exactly how much water you’ll need and how to properly use it below.
Roundup vs Water Mixture
The amount of Roundup per gallon of water you need depends on the type of weeds you want to kill and the Roundup product being used.
There are various options to choose from, but generally, you can do a simple calculation to find the answer. To kill seeding weeds, mix 2/3 ounces of Roundup Pro with 1 gallon of water.
But to protect crops and kill broadleaf weeds, the answer gets a little more complex. Either way, whenever the weeds come, you always want to get them away as soon as you can.
While you can just pull them out by hand, it can take up far too much time and effort. Roundup simplifies this process.
Read on to learn more about the types of weed killers and how much Roundup per gallon of water you need to use.
What Is the Ratio of Roundup to Water?
As we said above, the correct ratio will depends on the kind of Roundup you are using and the type of weeds you are killing.
Roundup Concentrate Plus
With Roundup Weed and Grass Killer Concentrate Plus, you’ll likely be spraying near your garden or trees. If the weeds are small, light, and thin, then mix about 3 ounces of Roundup per one gallon of water.
However, if you need to kill some stronger perennial weeds or clear them for a gardening plot, then you should mix 6 ounces, or 12 tablespoons, of Roundup herbicide per gallon of water.
Roundup Super Concentrate
If you’re using Roundup Weed and Grass Killer Super Concentrate, then you should mix about 1.5 ounces, or 3 tablespoons, of Roundup per gallon of water. This should take care of most small weeds.
For medium-sized weeds or vines, mix 2.5 ounces for every gallon of water. Remember, more concentrate makes the mixture more potent, allowing it to kill bigger weeds.
Roundup Pro is ideal for perennial weeds that have seeded and started to form buds. If you are killing weeds that are currently seedling, then mix about 2/3 of an ounce of herbicide per gallon of water.
For more dense weeds, use 2 ounces of herbicide per one gallon of water. However, if you need to kill woody vines or thick brush, you may have to use up to 13 ounces of Roundup Pro herbicide per one gallon of water to fully eradicate them.
Roundup Poison Ivy
Roundup Poison Ivy kills 200 types of weeds, including poison ivy, poison oak, and poison sumac. Since the product works quickly, you can keep your yard in good shape and let the kids run free soon after application.
The weeds will absorb the chemical immediately, and you’ll see results within 24 hours. For each gallon of water in your sprayer, add six ounces of Roundup Poison Ivy. Then, spray the roots to keep the weeds from growing back.
This concentration is strong enough to kill the most stubborn weeds around your home, patio, and driveway. It’s even rainproof if applied at least 30 minutes before the storm begins.
How much Roundup do I need per 10 acres?
For larger plots of land, you’ll need to know how much Roundup you need per acre. Roundup recommends using up to 44 gallons per acre. The volume of the spray should increase through that range to ensure you kill all the weeds.
Generally, one gallon of a Roundup solution covers about 1000 square feet. If you multiply the number of acres by 10, you will need roughly 440 gallons of Roundup solution per acre.
How much Roundup do I use for 5 gallons of water?
The following ratios for Roundup are based on five gallons of water:
- Roundup Concentrate Pro: You will need between 15 and 30 ounces per 5 gallons of water.
- Roundup Super Concentrate: You will need between 7.5 ounces and 12.5 ounces per 5 gallons of water.
- Roundup Pro: You will need to use 65 ounces per 5 gallons of water to eradicate thick bushes and dense weeds in your field or garden.
- Poison Ivy: Mix in a 24-ounce container by adding 1 ounce of concentrate and fill with water.
Are there any other ways I can kill my weeds?
There are many other natural remedies to kill your weeds without using Roundup. These include:
- Dish soap
- Corn gluten meal
- Concentrated vinegar
- Boiling water
The Roundup to water mix isn’t a cut and dry answer. If you’re using a concentrate, that ratio decreases.
But for most homeowners using Roundup Pro, 2/3 ounces of Roundup Pro per gallon of water is a good starting point.
