Spray Frequency

[Summett]

I am a homeowner who is tackling a pretty good bout of clover. My lawn was only established last year, so i didn't do too much weed control then as i was trying to establish it throughout the year. So, this year i'm tackling them.

Last week i sprayed Speedzone and had (or having) pretty good results so far, and my question is that if i have to spray again, when would you all suggest?

Learning (from this site) that clover may be a sign of low nitrogen, i plan on "feeding" it on a pretty regular program going forward, so wondering if i should hold off until the fall should i need to spray it again, or should i hit it sooner than that to combat the clover completely. According to the Speedzone suggestions, it should only be applied 2 times a year.

Any thoughts or suggestions would be helpful. Thanks!

wait 2 weeks before re-spraying.

I believe in most cases, you can only "blanket spray" (your whole lawn) twice a year. If you just spot spray, this shouldn't be a problem. Don't spray the speedzone above 85 degrees. I like to keep it below 80. Only spray where the weeds are, since it will not prevent weeds.

It can take up to 2 weeks for the weeds to "die" and disappear from the lawn. And it could take even longer under dry conditions.

Thanks Lilmarvin. I guess my question revolved more around blanket spraying again. Although I was going to give it a couple more weeks to see how it looked. Maybe by then spot spraying would do the trick, but I was just curious on the 2nd blanket spray.

Do your second "blanket" app in the fall. Mid to late September should do the trick. Spot spray once a month would be ok

If you have a big weed problem, I'd blanket spray twice in a row. Give the Speedzone about 3-4 weeks to see what weeds you actually killed, vs. what weeds just got top-burned. Then hit it again with a standard 3-Way herbicide.

Sometimes weeds will survive one blanket spray, but virtually NOTHING will survive two when they're back to back.

This way, it's under control and easy to maintain via spot spraying from there on out.

Good point. Very true. Whoop is up late or is it up early in Utah?

I was so beat that I went to bed at 9pm. But, because I've been running on 4-5 hours of sleep lately, my body decided to get me up at 1:30am!!!! Aaaaargh. Today's gonna be a looooooong day.

Boosting the nitrogen level is the right thing to do. Whether you spot spray or make another blanket application, be sure your mix includes a spreader-sticker to get the best results possible.

Without seeing your results or the extent of your problem and not knowing what rate you used or how well it was covered, I would say do not do another blanket application at this time. Wait until fall, give your fertilizer applications time to work, wait for more favorable weather before using your one remaining allowable blanket application for the year. Even though a winter has passed, it is still a new lawn that probably has not matured yet. If the first Speedzone application is showing signs of working I think you will be further ahead to get your mowing height and frequency, watering schedule, and fertilization fine tuned.

Thanks all for the replies. As suggested, i think i'll wait a little to see how this 1st spray works itself out, and then probably blanket spray again (while putting the nitro down with a good program).

I've seen many posts before about utilizing a "sticker". Any suggestions that a consumer might be able to find?

There is a JDL/LESCO in Brooklyn Park. Looks like it is about 50 miles from you. It is under $30 for a gallon and will last you forever. I'm sure they could UPS it if you can't get by there.

Big box stores might have some version of it, I have never looked at Home Depot or Lowes for that.

Alternatively, you could use a few drops of dish soap in your mix.

Thanks foreplease. I knew that Lesco was pretty close, i guess i was under the assumption that they were more of a wholeseller and sold to those in "the business". But i could be wrong on that. I'll check with them.

Thanks for the tip on the soap too.

Do a little background before you head to Lesco (EH Griffith, ebay even). Locally, they always try to screw me when I go in there at one of the stores so I usually go to a different Lesco or another landscape/fert company. Sometimes I have no choice if they have something I need in stock fast. I usually get them to knock off 10-20% off the price.

Brooklyn Park store is closed. There is a John Deere Landscape in Medina. You could check with any local farm co-op
