Concern® Weed Prevention Plus® for Lawn Care 8-2-4 - 25lb 2-Bags
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.

Existing Weeds
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.

Review Rate FAVORITE organic gardening pre-emergent weed preventative!!This is my FAVORITE organic gardening pre-emergent weed preventative. I have a huge yard that requires several hours of weeding every day UNLESS I apply Safer Brand corn gluten meal. When I apply that in ideal conditions, I only have to weed 1-2 hours a week. Yeeehaww! This year my biggest issue with the product is getting the neighbor's ducks and chickens to stop coming over to snack on my weed preventative. :-D

Review Rate Decent pre-emergent, only good option for organicAfter researching options for organic pre-emergent fertilizers, it seems corn gluten is really the only choice. It's expensive, but helps to buy a 2- or 3-bag combo. Free shipping is also a nice considering the weight. As for the effectiveness, it was OK in my first year using it. Had lots of clover, that's about it. Not sure this stuff is effective against clover though. I also read that it takes a few applications over a couple years to really build the effectiveness of corn gluten, so I will be re-applying next spring. Overall I'm pretty happy with it. Cost is the only reason to downgrade to 4*

Review Rate Great productHave applied this once so far and already notice the weeds dying and my dog was able to enjoy the backyard still without worry. I can’t wait to apply the second round and start getting rid of all the foxtails and dandelions.
-
Review Rate Excellent customer service backing an excellent productBefore I applied, I had questions. Called the 800 help number and had a very useful conversation about the application rate and how to get it right - based on that, a 5. Ease of application - a 5. My lawn looks great right now. A little too early to know if the seed suppression is fully effective, but so far, so good. Based on this experience, I would buy again from Safer.

Review Rate Looking forwood to using this productHave not applied this yet . When can I apply this product
Response From Safer Brand®Lauren : Consumer Relations RepresentativeHello Jack,
The first application to your lawn should be in early spring, approximately 3-5 weeks before weeds begin to sprout. This is about the time when daffodils and crocus flowers are in bloom. We recommend reapplying in late summer when the temperatures become cooler to help combat late season weeds. If using in a garden, it can be applied at any time.
Please feel free to contact our Consumer Relations Team at 1-855-7-ORGANIC (1-855-767-4264) with any additional questions. -
