How to apply: ROEBIC Foam Tree Root Killer
358414
..... Three days ago, at the first sign of this back-up, we called in a major drain clearing company. After inserting a 3" then a 4" root cutter into the drain, everything was running again. Then inserted a camera inspecting the job. Small areas of root were still hugging the wall in three places. They supplied us with their own root killer product, but it doesn't foam up. Roebic Foam FRK 6 attacks more areas...the walls in the pipe. $21 is a small investment if it kills fresh cut roots and keeps them from returning. I plan on repeating this twice a year...always.

CAUTION: when preparing the application process, add the following tips to their written directions. After reading other helpful reviews, I have details worth noting.
Yes, transfer the contents to a small bucket or large can. Break up lumps with a putty knife or similar tool. Because the neck of the container is only 2" wide, you won't be able to empty the contents fast enough into the toilet bowl. The bottom of the container is tightly packed with crystals, like a fine sand. What I did, do a practice flush and get a read on the highest water level. If you can regulate the water in the bowl, less water is better, preventing a foaming overflow when crystals join water. DON'T put content into bowl when the water is rising. Wait to pour crystals in bowl as the water starts to recede. Thus, the foam is going down and not rising. Most of the foam will drain out. Follow with another flush or two depending on quantity of water in bowl. I did this tonight. In the morning, back to normal. Expecting great results.

Dont kill on contact it takes a few minutes. A little trick put boric acid in the plants instead it won't harm the plants and kills worms, those nets and other stuff.

I've had 95% success in rooting cuttings using this rooting tray a humidity dome and Clonex rooting gel.

I pH adjust my water and add Foxfarm Big Bloom for a light nutritional boost to achieve these results.

I wish you luck!

We recently planted several trees and one of them was far away from the house with no easy way to water it. I purchased the treegator (jr due to height issues w/ the tree in question) and came up with a way to transport water to it using a cooler and 6' water hose. It works great and our dying tree is already showing new signs of life. highly recommend. picture attached.

Honestly I'm not sure if it worked or not; if it's accelerating decomposition it doesn't seem particularly fast, but I didn't do a side-by-side comparison to be sure.

I will say that you need to be careful with this, because the recommended next step is to burn the decomposed stump out with charcoal, which I did.  And the stump burned...right down to the clay soil, which is now baked solid in my planter box.  (This is not a reflection on the product, just a note about the process).

Use gloves and have a putty knife handy! Man this stuff is impossible to get off your hands... Please don't make the same mistake I did.

I used this with some copper wool to seal a few seams on my roof that I knew a roof rat was getting in from. Standing on a 12 foot ladder, I stuffed the copper wool in and sprayed this into the crevice. The first time I did it, the foam expanded a bit past where I wanted it to and had to get a putty knife/spatula to smoosh it back in. Overall, I am pleased with this, but took off two stars for the applicator straw and trigger as they get gummed up very easily.

This stuff is very easy to use. The packaging is nice, with directions right instead telling you exactly how to use it. I just did this to my tree today and it turned out gorgeous. It looks just like snow.
The only thing I suggest, is, if you can, do it outside or in a garage, as it does get everywhere. I laid a sheet down because I did mine inside and the clean up wasn't bad. Definitely recommend this instead of spending extra money on a snowy tree.

This product works great. Had an issue with Oaxalis spreading in my back lawn which is Hybrid Bermuda.
Regular treatment eradicated it within a summer season. Keep a bottle handy for spot treatment afterwards.

Here is how to do it. Drill as many holes as deep as you can. 1/2 inch is great. Fill the holes with lye or Drano. Get your garden hose, stand back and spray water on the stump. Expect to hear some noise and a little steaming. The stump should crack between the drilled holes as well as the circular growth rings. Water as required to dissolve the lye but not so much to run into the ground. Once the stump has bleached out, start pouring something like kerosine into the holes Check daily and keep filling the holes that are not full.. Again try not to get any on the ground. Now this is the fun part. Buy a bag of Charcoal briquettes and lighter fluid., Also use a wet vacuum/ shop vacuum that is able to blow.. Get a ,metal pipe 6-8 feet long and use duck tape to attach it to the hoes and secure the pipe so that all air from the shop vac will exit the pipe that you just taped onto the hose. At night get a lawn chain, possibly an adult beverage. Set the bag of briquettes on top of the stump. add some lighter fluid just like you are ready to BBQ. Once the briquettes are really red & hot. Turn on the shop vac & make sure it is on blow. Aim the pipe at the center of the tree stump. Within minutes the stump will start ti disappear, the stump will glow white hot. It is like carving the stump with lava. Once dirt starts blowing out of the stump, move the pipe to edges of the bowl shape you just created i the stump. If tou are persistent enough you will even burn all of the roots out. You can place a1/4 inch thick piece of metal minimum between the stump & anything else that is flammable.  I take no responsibility for your actions, as every situation is completely different. Contact a stump removal professional if you have any questions or there is any possibility that anything but the stumpcould burn.

I used this on those pesky weeds that come up through cracks in the cement. Within 48 hours, most were wilted but not annihilated, which is what Roundup usually does. I've always found Roundup to be the biggest killer of them all.

I do like the foam, because it may be less likely to blow around in the wind, although I can't confirm that. While it has a very narrow spray, it also spreads out over the weeds a bit, without spreading out too much to the surrounding area. The sprayer is pretty strong, so you can be three feet away and still shoot it where you want.

I admit I didn't use it as an edger. We use natural fertilizer and weed products in our lawn, so I didn't want to kill grass with it.

If this is cost effective, or if you can't get right in front of the weeds (to avoid more traditional spray that might blow in the wind), this may be the product for you.

Actually worked better than the commercials! On an island we have several C-vans for storage and the roofs were starting to leak. I broomed off the top and the spray penetrates the light dust and "bites" in for surprising adhesion. Fill larger holes with expanding foam. Wait over nite then protect and seal with Flex Seal.

I used a bag of this to fill in some dead spots and it worked like a charm. There are small seedlings everywhere I spread it, with better results than I've gotten from anything else.

Waterweed works great, just make sure to cut a piece off (razor knife) and kneed it really, really well. I went through 2 tubes, using about 1/3 tube at a time and it worked perfect, sticks well and hardens like a rock. I stuck it to fiberglass & metal, let it cure for an hour and then coated it with 3m 5200 sealant. They work well together and really create a great filler and seal when cured.

This is an excellent product to stop roots from trees,  also works as a weed barrier for many years to come.

After 1 week of applying this to my inside potted orange tree, the complete topsoil is full of fungus. It is blossoming and Im hoping this hasn't harmed the fruit or cause the tree to die. I had applied 2-3 tablespoons to the top and watered well. I am returning the product, which I was going to use next fall on grapefruit trees in Arizona.

This stuff acts like a wetting agent or surficant. Mixed up some foliar spray and the water was bubbling like soap. Outstanding product. Does exactally what it should for a foliar additive.

This is a very environmentally safe product compared to common sewer root killers with copper. You need to go to root X's website to learn about how it works and why it is a better solution that the off-the shelf items. You can't really evaluate it until around 3-4 months later when it prevents the roots from growing back after I mechanically removed the existing roots. Hopefully I will remember to post an update then. It was easy to follow the application instructions. The mfg website says the product is only available from plumbers & I didn't care to contact the dealers in my area.
