I just finished rehabbing my sprinkler system and As I gear up for spring my plan was to core aerate, overseed, and top dress. I’ve scanned (with an APP) many parts of my backyard and it’s come up as Kentucky Bluegrass. So I bought some seed (trying the pre-germinate method). A few other parts of my grass came up as St Augustine (what I have in the front) and Bermuda…
How will it look if I overseed KBG over the whole backyard? Will that give me a fuller greener lawn? Will KBG eventually be the dominant grass back there? Are the other grass types problematic?
Just not 100% sure how to attack this. Any advice is appreciated. I’m in Souther California and my backyard is 1/2 full sun and 1/2 partial shade.

Late summer/early fall is the best time to seed cool season lawns.
Regardless, if you are you looking for information about how to overseed a cool season lawn. You can find a comprehensive guide [in this post here.](https://www.reddit.com/r/lawncare/s/pUsKCxyvwQ)

Welcome to the never ending battle of lawn care! Happy to have you. One of the best things you can do and it’s optional, is get a soil test and see if you are low in any nutrients or high. You can plan fertilizer from there.
I don’t recommend going crazy year one as you can usually see a solid improvement with so minor changes. First is mowing regularly, keeping it around 2.5-3” during growing season which is spring and fall. And 3-3.5 during summer. I try to cut twice a week in the spring and as needed in the hotter months. Another thing is to just get a basic 4 step fertilizer program from and Ace or Scott’s. Just to get some stuff down and feed it.
Another thing I did for fun was to aerate. Walk around and stick a screwdriver in the grass when it’s not frozen. If the screwdriver goes in fairly easy you can skip this. If you get it in a little before resistance, you can opt for this. You can rent the machine if you’d like, it’s a work out but it’s kinda fun. Do a pass in one direction (left to right) and then a second in the other (front to back)
If you survive this year and still think it’s fun, get a plan in place for next season if you want to make any changes.
Edit: if your going to aerate do it before you put down a weed prevention application
