I use all liquids, no granules. However, my applications are done in 1-2 gallons/M through either a walking boom or single nozzle wand with a fan tip. The Chemlawn gun and tip are only for special high volume applications where the goal is to put down 5-10 gallons. Otherwise, the pattern is poor for precision, low volume coverage. I can do an acre in an hour or less with a three nozzle walking boom.

 

I also use "All Liquids". Gallery is a great Pre-Em and needs about 2 gal. of water/M. I have those big spreaders, heavy bags of fertilizer, but would never go back to them of these 1/2 acre lawns. Another feature is that I water in the fertilizer after each application and will not accept a client that does not have irrigation. Also, I will not let my clients do anything to their lawn because I cannot second guess them. I'm dealing with a suspicious area in a client's lawn now. If I find that they are putting anything down themselves, that is a breach of contract and will not accept them the next year. I treat a lawn 12/year. Granted these are in the south and it never get much below 35 degrees.

 

never put out pre m yet but on my jr you can put down 1gallon per k just by changing the tips thats at 5mph could slow down to 2.5 mph and put down 2 gallon per k...i myself agree with roy i wouild want control of the irrigation system..just use the 1gal per k tips and run the sprinklers...

 

Never had a problem with granular pre-emergents. Split apps are the way to go.

A ride on is perfect for granular pre/fert, with the spray set up to spot any weeds with herbi.

Unless you had REAL small lawns, liquid pre through a ride on just isnt worth it.

 

Every liquid preemergent I know of suggests it be watered in with 7 - 10 days. So if it doesn't rain soon, or if the homeowner does not water, the effectiveness is reduced. Also, dry preemergent products can be safely spread into & underneath ornamentals & low-growing trees. These are the reasons why we prefer granular preemergent products compared to liquid. We prefer the non-staining ones.

 

We have been applying granular applications and have found that the results to be pretty good.

 

I live in West Texas so if you want a yard you have to have an irrigation system. So that isn't really an issue. I always instruct my clients to water after 48hrs so the post emergents have plenty of time to absorb before it is hit with water.

Those of you using liquid fertilizer, how often do you apply? How long can it sit on the lawn before it needs to be watered in?

Most of the grass in this area are Bermuda or St Augustine. I have a few Buffalo grass and Zoysia or Sea Isle Paspalum customers as well. Which brings me to another question. I have a lot of mixed grass yards with St Augustine/ Bermuda mixes. My current situation I have 2 100 gallon and a 80 gallon v bottom for custom mixes. I mix one for MSMA product and another tank with broad leaf depending on the weeds present for the St Augustine, Speedzone and Trimec Southern are the most used. I switch from tank to tank to hit the grassy weeds in the Bermuda. Since all the ride units have only one tank how do you approach this? Just use the Speedzone and then spot spray MSMA for the grassy weeds with a pump up?

I appreciate all the replies.

Turf tech I can only comment on liquid fert i apply 3 times a year and it does not need watered in. part of it will be absorbed through the leaf blade the rest will washed off with the next rain.
