How It Works
An effective plan of attack against weeds is to get them before they start! Concern® Weed Prevention Plus® is powered by corn gluten meal, bone meal and potassium sulfate. Corn gluten meal suffocates and suppresses weeds before they begin to grow, while bone meal and potassium sulfate gently fertilize your lawn for lush, green grass.
Corn gluten is a by-product of the cornstarch manufacturing process and it has the ability to prevent seeds - especially those seeds of pesky weeds found in your lawn and garden - from growing roots and maturing. Corn gluten meal is combined with a natural fertilizer in Weed Prevention Plus® to give your lawn a nutrient boost for fast green up and growth.
Get Ahead of Weeds Before They Start
When using a weed pre-emergent, timing and temperature are key. Be sure to apply Weed Prevention Plus in early spring, so you attack bothersome weeds before they sprout! As a general rule, Weed Prevention Plus® should be applied when crocuses begin to bloom or when forsythia blooms start to drop. This timing will vary depending on different geographical locations and climates.
It’s extremely important that you apply Weed Prevention Plus early in the spring while the weeds are still germinating below ground. Once applied, the corn gluten meal works to prevent weed seedlings from successfully germinating. And the best part is that children and pets can play on the lawn immediately after application since Weed Prevention Plus® is composed of natural ingredients!
Lawn Food for Fabulous Lawns
Using Weed Prevention Plus® not only prevents weeds, it also fertilizes your lawn at the same time! The slow release fertilizer will be released into your lawn at a steady rate over a few weeks to encourage the growth of lush, green grass without burning your turf.
With an NPK analysis of 8-2-4, your lawn is getting the important macronutrients it needs to grow healthy and strong. So what exactly do these numbers mean and why are they important for lawn growth? Below is a simplified breakdown of each one:
8% N=Nitrogen – promotes leaf growth & fast green up
2% P=Phosphorous – supports flower & fruit development
4% K=Potassium – helps deep root development & general plant health
These numbers are all important because they show the percentage of each macronutrient contained in the fertilizer. Higher numbers don’t necessarily mean a better product when comparing the NPK of different fertilizers. What’s important is how these nutrients are released into the soil. When nutrients are released at slow and proportionate rates, there’s less chance of you finding burn spots throughout your lawn.
Nitrogen is the most important macronutrient for lush, green lawns, so that’s why it comes in at the highest number: 8%. Potassium is great for promoting strong roots and overall lawn health, so that’s why ours has 4%. Phosphorous is not as important for lawns to grow, so we’ve only included 2% phosphate in Weed Prevention Plus®. Since lawns stay in the vegetative state for the entire life cycle, there’s no need for extra of this bloom encouraging nutrient.
How to Apply
Take special note of the weather conditions for the next few days following your application of Weed Prevention Plus® on your lawn. For best results, make sure there is a going to be a few rain-free days in a row after you apply. After Weed Prevention Plus® is spread throughout your lawn, thoroughly water your entire lawn to ensure the corn gluten meal begins to absorb into the ground. Then, allow it to dry out over the next few days, and as weeds try to sprout, their roots will die and they won’t be able to develop.
If you’re looking to grow new grass on your lawn, you will need to wait at least 6 weeks after your application of Weed Prevention Plus® to sow new seeds. Because corn gluten meal is so effective at suppressing seed germination, it can potentially suppress the growth of new grass seed as well.
Great for Gardens
Weed Prevention Plus® is great for preventing weeds in and around flower, fruit and vegetable gardens as well! Corn gluten meal doesn’t change soil pH, and it won’t harm any of your established plants, so feel free to spread it around your blooming tulips and growing tomato plants. If you’re transplanting already sprouting fruits and vegetables into your garden, they’ll be safe around Weed Prevention Plus too. And, the added fertilizer will help them grow big and strong!
If you’re looking to start your garden from seed, then you’ll need to wait 6 weeks to plant your new seeds after applying corn gluten meal to your garden soil.
Effective Against a Variety of Weeds
Weed Prevention Plus® is effective against a variety of common garden and lawn weeds including:
- Annual Bluegrass
- Black Medic
- Black Nightshade
- Buckhorn Plantain
- Catchweed Bedstraw
- Creeping Bentgrass
- Curly Dock
- Green & Giant Foxtails
- Redroot Pigweed
- Wooly Cupgrass
- And much more…
Corn gluten cannot be used to kill existing weeds. Because the weeds have already sprouted, corn gluten’s powers are ineffective at suppressing the weed’s root growth. In fact, by applying corn gluten meal to existing weeds, you’ll actually be feeding it like you’re feeding your lawn because of the fertilizer in Weed Prevention Plus®.
In order to kill existing weeds, more extensive measures will need to be taken. Use a contact weed killer like Safer® Brand Fast Acting Weed and Grass Killer to kill weeds on contact. This weed killer is compliant for use in organic gardening and won’t move through your soil to damage nearby plants and grass. And, if you can, place mulch on top of the established weeds you killed to further prevent regrowth and new blooms.

- All About
All About Weeds
Unwanted weeds can cause harm in your garden if left unattended. They can crowd out the flowers and vegetable plants you have worked hard to cultivate.
Weeds can also cause damage to sidewalks and cause cracks in driveways and other outdoor surfaces; and let’s not forget how weeds can take over a backyard.
Weeds are typically just plants that are growing in the wrong place. Most weeds are just the natural flowers and plants that grow in your area and some may have been introduced in the past for medicinal, culinary or decorative purposes. So if you are wondering how to classify weeds basically, if you didn’t plant it, and you don’t want it in your lawn or garden, it’s a weed.
Unwanted weeds can cause allergic reactions for some people; some of them have jagged leaves and many of them are unruly and well, they grow like weeds, taking over your garden and crowding out the plants you have spent time, energy and money on cultivating.
- Control Options
Control Options for Battling the Weeds in your Yard
To control weeds, maintenance is key. If you’re looking for organic control options so you can still walk in your grass and spend time in your garden without worrying about the harmful effects of chemical residuals, read about the two types of solutions for weeds that are approved for organic gardening.
A contact killer, herbicidal soap will kill any weeds or grass that you spray it on and only those plants. The great thing about herbicidal soap is it won’t run through the soil and it won’t kill nearby plants.
It works great to kill weeds or unwanted grass within hours on sidewalks, driveways, between cobblestone walkways or outdoor pavers.
Also, spray it in your flower bed on those pesky plants you don’t want around. Just make sure you don’t accidentally spray it on your flowers, vegetable plants or other ornamentals because herbicidal soap doesn’t differentiate between plants you like and weeds you don’t like.
Use herbicidal soap as needed throughout the gardening season to keep weeds that happen to sprout up, under control.
Corn Gluten is a natural, pre-emergent, herbicide, which means it kills the roots of sprouting seeds before they can take hold so the weed will never grow. It works best if you mix it with mulch or into the soil for flower beds or apply it to the lawn then water it. If it rains heavily in the 2-3 days after the initial application, you’ll want to reapply, so watch the weather forecast. Reapply every 3-5 weeks for best results.
If you apply corn gluten in the early spring to your flower bed, vegetable garden or lawn, you’ll be greatly reducing the number of weeds you have to spray with herbicidal soap or pull throughout the growing season.
If you are planning a garden that you’ve planted from seeds, don’t use corn gluten until the flowers or vegetables you’ve planted are firmly established plants; otherwise corn gluten is a safe, natural way to control weeds throughout the season on all plant types. You can even use it on fruits and vegetable crops, up to the day of harvest.
If you love feeding the birds, but hate the mess and all the weed and grass that grows from the seeds all over the ground, sprinkle an ample amount of corn gluten into the ground below the feeder to stop those seeds from germinating.
