Bonide Captain Jack's Lawnweed Brew, 32 oz Concentrate, Fast-Acting Formula Controls Weeds, Moss, Algae, Lichens & Disease

Works great! Nuked the horseherb that was taking over large swafts of my yard without bothering my bermuda one bit!

This saved us from being overrun by dandelions! We haven't used herbicides for over a decade because of how toxic most are. We were trying to weed dandelions in our grass by hand. We couldn't keep ahead of their spread! (And it was so much work!) I've been using this product since spring of this year and it's now late summer. I spot spray the dandelions in our lawn and in our periwinkle. I really saturate each dandelion. We are making great progress! Our lawn looks much nicer. I'm using a two gallon pump sprayer. I also bought a hose sprayer that mixes as you spray for our rental house where the yard is FULL of dandelions. (But I haven't tried it yet.) With spot spraying I find I need to go around and check ideally sometime between 12 hrs and 2 days for dandelions that aren't fully dying. I spray those again. Often one spray kills the dandelions, two times almost always does. But there may be some extra hardy ones that need to be sprayed more times depending on how well established they are. I think once we get the dandelions eradicated I'll need to do my method twice a year to maintain a dandelion free yard. I'm hoping I'll only need to spray each one one time at that point since they won't be established. I try to spray when it won't rain for at least a couple days and also pause our sprinklers from the time I start spraying until a couple days after my final spray. Also I go around and grab any flowers left behind after a day or two so they won't re-seed. (Especially the ones that ripened after spraying.) They're easy to grab because the stalks rot after spraying. Also watch the temperature. This spray works best when it's between 60-80 degrees outside and where the temperature will stay in that range for at least a few hours after you spray. The pores on the leaves close at hotter/cooler temps and this product must absorb through the leaves. I feel like the lawnweed brew actually kills dandelions better than the deadweed brew, although the deadweed brew works on a lot more weeds and works really well and really fast. (It kills all plants, though, so you can't use it in your lawn without killing the grass.) Also if you spot spray you will have black spots in your grass for a while after you spray until the grass recovers. After that it'll be healthy and beautiful!

This product did nothing. It didn't kill any vegetation at all. Complete waste of money, effort, & hours of my time

I was hoping to kill some weeds without damaging grass but the weeds survived. I love the idea of being natural and non toxic but it just didn’t kill the weeds. It is iron based so it did green things up. I was happy with the price and the fact that it was concentrated but I guess if it doesn’t work on the weeds- I won’t buy it again. FYI, Captain Jacks Dead Weed Brew DOES kill the weeds. They turn brown within minutes!

I applied this product in late January on a 60 degree day. It took two aplications to see that it did do what it was adversized to do. It was easy and safe to use . it did kill the clover. This product was cheaper as compaired to other. very effective on my lawn. I feel like this product will do better when the weather is warmer and the ground warms up. I am happy with this product.

The first time I used this product I did not get very good results. The little measuring cup that comes with the bottle is a little hard to read and I think I did not add the full 6 oz to 1 gallon of water. The second time I used it.......Shake the bottle before measuring. I measured 6 oz in a glass measuring cup. Added it to 1 gallon of water in the pump up sprayer. Added 1 teaspoon of dish washing soap to act as a wetting agent to help the solution sting to the weeds. Gave the pump up sprayer a couple of shakes to mix everything. Pumped up the sprayer and sprayed my weeds I did not see same day results, but in 2 of 3 days what I sprayed was blackened and dying. I really like the results. It did not kill my St Augustine lawn, just made it greener and it killed all the weeds ! I am in south Texas and we have a 10 month+ growing season, and weeding never ends. Love this stuff. Next my son is going to try this on his dandelions in Madison Wisconsin. I will report back on his results. Cheers!

I've used the spray bottle for the last 2 years and it works great. I decided to try this concentrate and broadly spray the lawn this year. Even using a pretty strong water ratio (I could see the brownness as I sprayed) this just didn't apply to the weeds as well as the spray bottle. It's more work using the spray bottle for sure, as you have to get on your knees and spray each weed, but it just works better. After using this concentrate, most of the weeds looked a little sickly, but not straight up dead like I'm used to with the direct spray bottle application. I'll be going back to the spray bottle next time.

I've been using this for about a year now. It is the only product I've found that does not kill my Floratam grass. It is pretty effective if you use it every 2 weeks, but if you miss a treatment, your weeds will come back. Doesn't kill dollar weed and takes several applications to kill most other weeds, but it still beats pulling by hand.
