I have a normally scheduled program, but what do you guys do about new customers? I don't spray full time, it is just a supplement for my mowing customers. So I spend a few days spraying and then stop.

What is the absolute minimium between apps you could use? I would like to get everyone on the same schedule. Looks like I will have 3-4 weeks since I last sprayed the new pick ups.

It all depends on the release curve of the fertilizer you put down, and the weed pressure in the lawn.

What did you put down for fert, what percentage was slow release? What is the release mechanism? (Poly Coated? Sulfer Coated?)

How bad are the weeds in the lawn, what type of weeds did the lawn have, how healthy is the lawn. Do you have a soil test to reference back to?

Good grief Lush.

4 - 5 weeks.

Early in the year I keep them at 45 days apart. But on round three I will space them out to 60 plus days and use a 100% XCU product so it will keep them greener longer.

Lushgreen asks some valid questions, all things to consider.
Ignore the unconstructive comment on this thread.

I'm assuming your asking about spraying, not fertilizing?...i've always heard 4 weeks to be safe, but if you have had a lot of rain after your app i dont see waht 3 weeks would be a peoblem. keep in mind many states regulate how many times a blanket app can be done in a year.

yes just talking spraying. my fert is all granular and i'm very familiar with that.

What I'm asking is that about 5 weeks ago I did round 1 and it is now time to do round 2. between the two rounds i have picked up and sprayed multiple new clients. i want to get everyone on the same schedule so i don't have to go out and spray 1 or 2.

4-5 weeks? My schedule is much different than that.

Maybe thats because I use a different fertilizer than you. In order to give a true estimate, you need to know some specifics about fertilizer.

Many States are getting very restrictive about what types of fertilizers can be applied when, because nutrients are showing up in waterways. The cause, homeowners (and commercial applicators who don't know what they are doing) over applying.

He could be applying AS, or a methyl coated season long fert for that matter, would you still make that recommendation?

Gotcha! Check the label on your herbicide, but I would think you'd be good to spray again on the regular schedule. If you blanket sprayed with round one, all you should need to do is spot spray the second time anyway.

If you spot sprayed round one, then I would continue the trend and spot again, unless for some reason weed pressures have increased since then.

Personally, I blanket spray everyone for round one with a good Ester based herbicide, and minor spot spraying is all I need for the rest of the year usually.

He said in the first line he has a normally scheduled program which is 4-5 weeks in most parts of the country.

He was asking when to do new sales that he does a round on later than his normal applications that still fall within that rounds timing.

They get done on the same schedule as everyone else which is.....4-5 weeks and if they are out of sync then that's the breaks. You can make up a week here or there and hopefully get them in line with the rest a few rounds down the road. If he is concerned about weed control timing a simple company generated courtesy service call will cure that.

I think you misunderstood his question, and got a little to "Into it"

It doesn't sound like he is applying some exotic fertilizer products, but standard products.


What does doing a soil test have to do with his original question anyhow.

Not to be a pud but if your state has integrated I.P.M. strategies for commercial applicators then blanket spraying everyone is in violation of those strategies and not cool with the environment especially using strong esters.

Do your lawns that you treated all last year really need a blanket application of esters each spring?

My returning customers may show a few weeds on edges or something but certainly don't need a blanket application.

Especially with esters.

I also don't use pre emergent on all round 1 customers. Maybe only 30% get it because most are not crabgrass or weed prone.

I usually go 6 weeks between apps, but in the spring picking up new customers I will go as soon as 4 weeks to get them on the same schedule as the other customers in the area. and usually new accounts need a second app sooner than established accounts to get them looking good!

Actually, as discussed with my Department of Ag rep, it is within Ipm guidelines. There are many weeds that will start in lawns in the spring that will be too small to see, and missed with spot spraying. By blanket spraying everyone one time in the spring, when the highest percentage of weed seeds are germinating, I get all the actively growing weeds, showing or not. This means less spraying later in the season, and happier customers.

Considering that I spray within the guidelines of the label on my products, and only under ideal conditions, my ester product is broken down in the soil long before it poses any kind of problem. BTW, except for the fact that it can volatilize in higher temperatures, how is it any more hazardous than an amine product?

You answered your own question.

I don't know. Maybe it's your area but most of my returning clients only have a weed here and there in spring and summer. I rarely blanket app lawns unless it's a new sale that's never had service or had poor service in the previous year.

I do have a select few customers that I don't blanket spray, because I rarely have problems. There are alot of people in my area that don't take care of their lawns, even in high end neighborhoods. Chickweed seems to germinate in even the thickest, highest mowed lawns. It gives us problems every year. By blanket spraying, it knocks it out before it gets a chance to take over. With the nicer lawns, it will be small enough that you can't see it below the 4" turf, but its there. Luckily, it seems easy enough to kill, but it you can't see where it is, and you try to spot spray, everything you miss will start taking over, causing a service call 2 weeks after you were there, and then you have to go back and spray more chemicals.

I use the ester for my R1, and amines for my spot spraying the rest of the year. With the ester, even the small amount that gets in the weeds growing below the turf is usually enough to kill it, even the ground ivys and other hard to control weeds. My R1 is over well before temperatures get high enough to volatilize the ester emulsion.

Every area is different, I am sure what you are doing works well and your customers are happy. This is what it seems to take to keep my customers happy, and my ag department seems to be happy with my program. I consulted then when designing it, both for the fert and the weed control.

Best of luck this season to you!
