You can use it anytime of the year to prevent dog pooh on your lawn (seriously). It stinks quite nicely (to dogs, not so much to humans) and dogs will steer clear of your lawns. I plan to buy it every year now.

Will green it harm my mature tomato plants

Asked by Bradley May 7, 2016
3
Answers

No, but it will prevent other seeds from germinating in the future. So if you plant from seed in to the ground, you may not have anything that grows. You'd have to plant an actual plant into the soil where you've applied it. The effects don't last forever though and the length varies based on many variables.

Can I use this in july?

Asked by BabyD June 27, 2017

Answers

Can use in July, but I would apply during morning or evening cool down. However the product will only prevent new weeds from growing. Those weeds that are already in progress will not die. My experience with corn gluten is that when used once in spring and once in fall it works beautifully.

Will this product be effective on lawns with weeds already sprouted?

No, its a pre-emergent. Must be applied before they germinate (March 1 summer weeds, September 1 winter weeds)

Can I use this product when overseeding the lawn

Asked by LTC September 21, 2015

Answers

No, it is a pre-emergent. Its main function is to suppress any growth of seeds. Once the grass has sprouted you can then apply.

Asked by steve January 6, 2020

I have used this product in flower beds to knock out clover and some other broadleaf weeds and it worked. But, as it turned out I just happened to get lucky and time it right this was a few years ago before I started learning more about lawn care and weed prevention. Since then, I have been studying lawn care by a fellow that worked from TrueGreen and ChemLawn for 20 years and has educational videos on YouTube designed for the home owner, not lawn care professionals. I learned a lot about how seeds propagate and also how pre-emergents work. So for best results for your corn gluten to work, you need understand the propagation cycle. The seeds produced by plants germinate three times a year depending upon the particular plant. If you apply a pre-emergent during those times, the pre-emergent prevents the seeds from growing roots and therefore, they are not able to sprout new growth and die off. So the trick is in the timing, and there is online help for that, or you can determine it yourself. The three times are when SOIL temps (not air temps) hit 55 degrees and 70 degrees. This happens three times a year - early spring soil temps rise from the winter cold to 55 degrees, late spring soil temps continue to rise to 70 degrees, and in the Fall soil temps fall from the summer heat down to 70 degrees. You need to get your pre-emergent down within a couple weeks of these temp changes. So like I said, this product did work for me, and I must have hit that window by sheer coincidence. If you time it with these key soil temps, you should have good results. You can either take a food temperature and stick it in the ground where these sand spurs are growing and monitor it. Or you can check online for soil temps in your area by visiting: http://www.greencastonline.com/tools/soil-temperature The nice feature of this website is that it has historical data. You can enter your zip code and find out current soil temps for your area, and you can also change the dates on the calendar and get historical information from previous years. This is very helpful to do as you can look up temps in past years to see approximately what time of year your soil temps rise or drop to these key temperatures. Using that historical data, you can get an idea when to start checking for soil temps in your area to hit that ideal window of opportunity to apply your pre-emergent. Here are some other alternatives I found on getting rid of sand spurs, I just happened to find these when looking up sandspur propagation. http://www.howtogetridofstuff.com/how-to-get-rid-of-sandspurs/ Here's the link to using pre-emergents by the fellow that offers lawn care education for home owners. I have used his entire lawn care restoration program and have had great results. Though he doesn't use corn gluten in his videos, (his focus is on crabgrass prevention) I have experienced corn gluten working personally, so you should be able to use it as as alternative. What is key here is how pre-emergents work and also timing to give you the best window of time for success, and he explains how to use the soil temps in this video along with how to measure with a thermometer. https://youtu.be/Oet1QS95kaY Hope this helps!

An I use it to kill grass around trees?

Asked by Cindy April 10, 2019
2
Answers

It will not kill anything that is growing. This is a pre-emergent weed killer, meaning it prevents any seeds from from germinating. So if you have seeds from weeds, or lawn, or plants on the ground, the pre-emergent will prevent the seeds from sprouting and growing.

Supposed to cover 2000 sf but only over about 1000 sf because the nozzle opening is to big and releases too much product at a time.

It is working very well
In northeast Ohio, I applied this in April and made sure it was not going to rain for 3 days. It is working very well.... no weeds as of May 20. I am buying more to reapply in 2 months. You can use it up to 4 times a year. Why don't they carry this product in stores?? You have to order online and pick it up in store. My neighbor just applied the regular weed-n-feed (poison) to their lawn and I'm choking on the smell. The Green It does have a slight odor when applying, but goes away in a day and it not anywhere near the awful smell of the traditional weed killers. Wish all my neighbors used this.....

Timing is everything! I used a chemical pre-emergent in the past and decided to switch to the corn gluten since we have pets and kids playing in the yard. Very happy we did. It does a great job without the chemicals. I live in the Southeast and I apply it on March 1st for the summer weeds and then the 3rd week of August for the winter weeds. Also did some investigating about corn gluten and it should be dry for about three days after applying. No more weeds in the yard, excellent! One other tip, I also use this in my landscaping beds (mulch, etc.) to keep from having to weed each year, excellent time saver. I can confirm though what others have said about the application method and it is hit or miss with some cans whether they simply squirt water or are actually applying the corn gluten (thus the 4 star rating vs 5 stars). I have found about 10% of the cans do have an issue. You can actually see the water turning slightly yellow and you will hear a different sound when it is working. Once I find a good can I will save the yellow top and switch it out with any cans that are having issues then it works fine.

Nice idea but dispensor issue
Home Depot review 9/17/2020 for the Green It 64 oz. Ready-to-Spray Liquid Corn Gluten Weed Preventer. Problem here is the product, being organic in nature from the corn gluten, does not have a thin and consistent texture in the bottle. The sprayer is a standard design used with various common chemical treatments (thin straw and small orifice). The manufacturer should consider having a bottle designed that works better with this product. On the plus side, liquefied corn gluten is less susceptible to being eaten by birds. Crows and seagulls, for example, like to feast on granulated corn gluten which removes a significant amount of the product from the lawn as well as the resulting damage from their pecking.

The sprayer provided had dislodged the straw that distributed the Green It. I have no idea how well the treatment worked as I was not sure anything or where the liquid was dispersed. Also seems like it is imperative that the sprayer be level when administering. That is very difficult to do.
