After a few years of overpaying for minimal weed prevention/ fertilizer service I’ve ended my contract with my local company to take it on myself.
In Fresno California, known for cool dry winters and hot and dry summers. Lawn started as tall fescue which I prefer but always fighting a war against Bermuda. I actually don’t mind the Bermuda in the warmer months since it takes the heat and dog traffic much better.
Any good recommendations for preemergent and general fertilizers?
Also I’ll add a few more screenshots of the following weeks for high and low temp references.

Not to be rude, but hire them back…
Seed and pre-emergant don’t mix.
Yes, no, yes
Preemergent won’t help in your battle with bermuda, only with helping control new annual weeds.
Air temps aren’t what you should be paying attention to, soil temps are.
With that combo at the same time, youre gonna end up blocking your seed from growth while feeding the existing weeds you have.
Skip the seed for now. Wait until around temps are crossing below 65.
So i’m no professional, but here’s what I did on my first year, and my yard looked better
first go buy a soil temp gauge. They are cheap and I just threw one in the yard that just stays there (doesn’t have to be high tech or anything). Depending on your yard and what state it is in Id go 1 of two ways.
The way i’m going this spring is:
If you want to prevent weeds, this spring you can put down preemergent once the soil temp reaches above 50 and it rains within 7ish days (I try to do it the day before it rains) Than in the fall once the soil temp gets below 70 you can seed your lawn. If you wait 2 – 3 months after seeding you may be able to put down more preemergent for the winter, but that’s pushing it. I’d just wait and make sure the grass seed takes and start again with just pre emergent the followign spring and fall. I’m sure there’s better ways to do this, but this will be my schedule I follow.
Should look something like:
March – Pre emergent
Sept – Grass seed (if needed)
Oct – Pre emergent ( if no grass seed put down)
water water water
Gotta wait AT LEAST 8 weeks before throwing down seed after pre-emergent.
What do you think the pre-emergent will do to that grass seed?
IT KNOWS NO BOUNDARIES – ONLY KILL
Don’t know what you’re doing but fired the guys that do?? Good luck with that
Despite what others are saying, I used Mesotrione (tenacity)when heavily overseeing and the results were great. My yard was 90% weeds and now is 95% grass. I hit the weeds in advance and power raked the shit out of them prior to seeding and second application of mesotrione. I am in zone 7a NC and did in fall

Preemergent when the forsythia bloom
That would’ve been a good question to ask your professional fertilizer guy before getting rid of him.
I’d wait to seed. You can use Tenacity preemergent right over top of fescue seed, no problem at all. But, you have it spray it again in 45 days. ( it’s only available as a liquid)
If temps are going to be steady, then yes, put down pre-emergant. It won’t do anything for Bermuda, as someone said, only broadleaf weeds and crabgrass. There are products that control Bermuda. Wait until fall for any overseeding.
