Problem with weeds in my lawn (fertilizer, seeding, crabgrass, violet)

[Jlalac]

Looking for assistance in identifying and treatment for these particular weeds. Not sure if anybody else is experiencing the same outbreaks on the island. The clover looking one comes back every year and spreads like wild fire.

Second pic is Crab Grass. Crab Grass will die in the winter but the seeds will come up in spring. Dont cut your grass too short and get Scotts fertilizer with halts. That should help a bit. best of luck. My lawn is a disaster from the old owner.

The one on left is easier to control by pulling it out at root.It is not an aggressive weed.The crabgrass like cmv said is treated in early April and again in late May with Scotts w/Halts. Doing it twice works for me.

I moved your thread to the garden forum.. these folks know their stuff.

The first one looks like a wild violet to me but I am no expert

You can use just about any broadleaf control, just make sure to follow the label directions. Do not use a product like Roundup in your lawn unless you want dead spots. For the crabgrass (2nd photo), you can use a pre emergent control as mentioned above. Even the professionals have had a hard time controlling crabgrass this year, so don't be disappointed with mediocre results. Its too late to get rid of crabgrass in your lawn this season, unless you want to try to pull it.

There are some sprays that will kill crabgrass but not normal grass. I can't remember the name, but we found one that comes in a powder form in a packet (like Kool-Aid - but crabgrass poison!) that you dilute into a sprayer. It also works on clover and other sedges (sedges are one of the most evil weeds to try to destroy...)

Best of all - it DOESN'T have a preventative, which means we can overseed.

So.. once you identify the weed (as everyone here has helpfully done for you) - get to a garden center and read the bottles, or ask for help. Usually the people will be very glad to assist.

In early Spring I use Scott's fertilizer with Halts.

Around June 1st I use Ortho Weed B Gone Max. The "max" is for crabgrass in order to get any that were missed by Scott's and managed to germinate.

Ortho is great for any other weeds I have in my yard. It comes in a concentrated formula. I had to buy a hose sprayer for about $10. I just fill it with the concentrate, set the dial for 1 1/2 oz (even though the bottle recommends 2 oz I find that 1 1/2 oz works just as well), and spray the yard. I do two passes in opposite directions to ensure maximum coverage.

be sure to identify what kind of lawn grass you have as different products work different on different grasses.

Thanks for all the advice guys. So is the first picture definitely a wild violet? I checked out the Scotts with Halts and it states it should be applied just once yearly in early spring. Ron I checked out the Ortho Weed B Gone Max but I only found it in a large hand spray bottle. The bottle didn't mention anything about diluting. Did you just dilute it in the hose sprayer on your own?

There are what's called "hose-end-sprayers". Ortho makes its own, it looks like a big plastic jar with a dial on its lid, and a handle built into the lid that attaches to the hose.

You dump the concentrate into the jar, usually there's a tube that goes from the lid down to the bottom of the jar -- make sure that's in place and tighten the lid. The bottle of concentrate will tell you what dial setting to use (1oz/gallon, 2 oz/ gallon, etc..). Set your dial. Connect your hose, turn the water on, pull your trigger ... SPRAY WEED DEATH!!!!

We use the concentrate for lawn weeds (in the back, where we don't care about overseeding) and for brush killer (nasty poison ivy)..

Good luck with your yard!
