Microbes are slow, too early to tell how well it works

Microbes are slow, too early to tell how well it works
I think this works based on microbial action, so it relies on soil microbes to eat up the thatch. It seems like this may have some microbes included, but I don't see a list on the labeling.I've made one application of this and haven't seen any noticeable changes. It's still a little early to tell though. If this works by encouraging microbes to handle the thatch, it'll take a while before the effects are noticeable. If it works, this is a great and less labor intensive way to detach, while still helping the soil improve itself.It has some fertilizers (potassium and iron) and humic and fulvic acids, so even if the microbes don't work out, it'll improve the soil.

5.0 out of 5 stars A simpler way to dethatch
Reviewed in the United States on March 29, 2024
Size: 32 ozVine Customer Review of Free Product( What's this? )
Dethatching a lawn can be challenging as so much debris builds up on your lawn over time. There is a real need for something that can move along natures natural degenerative actions. Petramax has come up with a great product that speeds up that natural dethatching process.

You simply mix 6 ounces of the product per gallon of water in a sprayer and then apply it to the area to be treated. Be sure to water your lawn 5 minutes after applying so that you get the optimal results. This product is a microbe booster and speeds up the natural rotting process.

The 32 ounce bottle can do 1,250 square feet. For best results it should be applied weekly during spring and summer months. It can be applied to all types of grass. When we used it we noticed that the degredation of our accumulation of mowed grass disappeared.

We feel that this is a great product and it does it's job well. We will be continuing to use it.

Easy to follow instructions, I am going to finish 2 more applications and hopefully see results. I have a very thick layer of thatch and this is my last ditch attempt before renting a power rake to destroy my lawn. Applied, no strong scent easy to see where it’s sprayed water after applying and let it do its thing

4.0 out of 5 stars Giving nature a helping hand
Reviewed in the United States on April 23, 2024
Size: 32 ozVine Customer Review of Free Product( What's this? )
First off I like the Petra products so when offered to give this a try I said sure. Knowing that this is not going to be a miracle dethatching process and will not replace a mechanical dethatching my expectations were pretty low. It mixed up easy enough and I do like the ease of applying with a spray versus powders & spreader. I may have been moving too slowly since it didn't cover as much as I expected. Watered it in as directed and then we had a few days of rain. Gotta say, I was starting to see a difference, although subtle, so we'll see how this does after several treatments into the season. This might make a great intermediary product to extend the time between mechanical thatching helping break down light thatch and clippings that accumulate. So far I'm a fan

5.0 out of 5 stars Grass is doing well with a host of products including this one
Reviewed in the United States on March 21, 2024
Size: 32 ozVine Customer Review of Free Product( What's this? )
I can't comment on this product solely by itself, because I've been using 5 of these products from Petra together at once. I know the Petra brand from their sprayers. I have one pump sprayer from them. I was excited to see their offerings of different chemicals. I applied to the backyard a week ago, and just did the front. Only natural rain so far, so no variations from sprinklers, and the backyard looks much better and has more growth (although some is weeds as I haven't started weed control yet). It mixed well in tank and was able to flow through the plastic filter bucket.

I'm hoping this product will help get rid of some of the dead grass that has been leftover after winter so the new grass can continue to come in strong. I would recommend considering the larger size both as it's cheaper per oz and depending on the yard size the 32 oz can go quickly.

3.0 out of 5 stars Dissolve some thatch and clippings…not dethatch
Reviewed in the United States on April 14, 2024
Size: 32 ozVine Customer Review of Free Product( What's this? )
Dethatching is an aggressive process involving dragging tines down to the dirt and pulling out half decomposed clippings and such. To be clear—this is not a “dethatch” miracle spray.

What it does do is introduce organic material to the clippings and thatch layer just at the soil level and boost the nitrogen cycle by attracting beneficial microbes and other natural activity. This process requires it to be hot and applied when grass is aggressively growing. You should see worm castings and probably mushroom activity the next day or so after applying. If you don’t then there is not enough organic material to start the process. Think of it like compost starter for the whole lawn. Mushrooms on your lawn are a high-five from Mother Nature. They are a vital part of the nitrogen cycle—Google it.

NB: I will not use this product until the temps are at least regularly over 90° in North Texas. Otherwise it’s a waste of time. But as I am asked to review this product prior to May then I can only make a conjecture as to what it will do based upon the ingredients. Once I am able to use it, I will use every 2-4 weeks depending on grass clipping yield.

I'm a bit of a lawn nut. I carefully plan everything I put down on my yard. This year has been a rough start because of illness.
I usually mechanically dethatch my zoysia grass at the beginning of the season. This year I applied this liquid dethatcher. So far it looks to have done a fine job and theoretically it's left more decomposed lawn food from the thatch being biodegraded vs physically removed.
There's definitely a smell and color to. I watered it in as instructed and that addressed the dark color on the lawn

5.0 out of 5 stars Convenient Way to Dethatch Lawn
Reviewed in the United States on March 8, 2024
Size: 32 ozVine Customer Review of Free Product( What's this? )
I have a layer of thatch in my lawn. This liquid dethatcher contains active ingredients that break down the thatch into smaller particles, making it easier for microorganisms to decompose and for the thatch to integrate back into the soil. It’s convenient and easy to apply with a hose end sprayer. It allows for uniform application across the lawn. It enhances microbial activity, breaking down thatch but also stimulating microbial activity in the soil. The directions for this lawn dethatcher are to mix 6 oz of dethatcher to one gallon of water and that will cover 1,250 sq. ft. of lawn.

Reviewed in the United States on April 22, 2024
Size: 32 ozVine Customer Review of Free Product( What's this? )
I mixed this up and sprayed a test area in the lawn that seemed like it had more thatch than other areas. It was easy to mix and comes in a resealable container. Grass has been actively growing in FL, so it should have been a good time to try it out. After two weeks, I have not seen any noticeable difference. I guess I should have taken pics and compared them, but as it stands, I still have a lot of thatch in that area. I will try again in another section now that the daytime temps are solidly in the 80s and 90s to see if that makes a difference. Will update if I get better results.
