BioAdvanced 5-in-1 Weed and Feed Granules - Kills Lawn Weeds & Crabgrass - Feeds, Greens & Strengthens Lawn - Treats Up to 4,000 Square Feet - 9.6 lb Bag

Been taking care of yards at homes I've owned since 1984. I put this BioAdvanced down in March. It has snowed twice since then (Chicago). I have a few Dandelions, but the grass is gorgeous, green and thick! Develop a version to put down in November to prevent Spring Weeds and make the grass Green as fast as possible in March, if it can be done. Thanks again for a superb product! (BTW...I used the season-long weed killer/preventer last year. The grass wasn't as green, but there were zero weeds the entire Spring/Summer!)

This product gets better results than the professional fertilizing companies I've used in the past. It gets rid of hard to eradicate weeds and lasts for several months. I suggest a few weeks after application using "Ironite" or a product that has the main or sole nutrient nitrogen for a really green lawn weed free. It's remarkable that the Bayer 5 in 1 eradicates crabgrass too. The only downside to the product is that it definitely has a chemical odor that lingers a a couple days or more. Pour the product into the spreader on cement so if you spill it won't destroy the lawn. Wear long sleeves, gloves, pants, goggles and maybe a mask. Your neighbors might think you're odd but hey better to be safe than have any adverse outcome from using any chemical. Keep pets off too for at least a couple days or until the odor goes away. Those are my suggestions for using this product a couple times of year versus multiple times fertilizing and doing it safely for a weed free, green (use a nitrogen nutrient), lush, professional looking lawn.

Everywhere I used it saw the grass grow better, although it did not fight some weeds effectively

This stuff won't work unless the lawn is wet, then it will stick to weed leaves and kill them. Application on a dry lawn will not work well. There was a rain the night before I applied it. The lawn was not soaking wet, but was very moist between the grass blades. Dandelions are dying and hope to see crabgrass die off soon. You use about half the amount of this for the same application area as Scotts, so you have to be sure you have good even coverage to kill the weeds. Also, dandelions become zombie weeds, still sending out flowers and gobs of seeds even though they are near dead!

Used this product for the last 2 years with mixed results. Since weeds are typically not as big of a problem in zoysia lawns to begin with, this product has predictably done very well when it comes to weed & crabgrass prevention. Almost zero weeds or even crabgrass even though I'm surrounded by untreated neighboring lawns. However, my results as far as green-up & growth promotion & overall health of my lawn have been poor. Lawn has been ravaged by dollar spot/brown patch in each of the last 2 seasons. With such a short growing season, the dead spots don't have much time to regenerate before time's up on the growing season. Last year, after a liquid fungicide stopped the problem, there was only time for about 1/2 of the damage to recover. To tell the truth, I regret ever going with zoysia grass to begin with (now about 10 years ago) It was billed as low maintenance & has proven to be anything but that. Now, faced with the nightmare scenario of removing it with it's ridiculous root system, that's just not an option for a 68 YO man.

If I could give this negative stars I would. I actually have more weeds in my yard AFTER using this. However, the feed portion of the weed and feed appears to have worked because my grass is a lot darker green. But I seriously have more weeds in the yard after using this and it is blowing my mind. I didn't want to believe that only good weed control could be applied through liquid form, but this product made me change my mind. This was applied at 6 in the morning AFTER the grass was "dewy" and then each area was hit for five minutes from my lawn irrigation system. Same day turned out to be dry and sunny later in the afternoon. You couldn't have any better conditions for the application to stick to broadleaf weeds, etc. Do not recommend this product to anyone looking for weed control because you'll be highly disappointed!

This actually works.

I have two large lawns that I irrigate. Each Spring, I get quite a bit of dandelion throughout my lawns and later in the summer, the crab grass and clover start to take effect. I have the clover under control for several years, but this pre-emergent worked really well this Spring in the dandelions. Ill update later with fall results.
