I have Zeon Zoysia that this is its first full summer of growth. I am learning as I go from this forum as well as online sources. I have been applying the 16-4-8 fertilizer about once a month along with Milorganite to get the growth started. The lawn is green and the starting to fill in (with a couple bare spots still but that is due to too much water and need for topdress). I just placed Mirimichi CarbonizPN on my grass as I was told it was a great product for root growth.

My question to the group is should I be applying some sort of weed prevention right now? If so, what should I be applying?
Supersod schedule for Zoysia says to but my local SiteOne guy said to hold off on weed control since I do not currently have any weeds in my yard. His reason is that Zoysia is dense and chokes out weeds. From his comments it sounds like I need to just fertilize for growth and spot treat when they do come up with a sprayer.

Many of you have some great lawns on this site and my goal is to be there one day. I am just trying to get my schedule down this year so I can make it routine in the coming years.

What says the group?

I would say yes, but only if you believe the roots are fully established. While zoysia gets very thick, weeds will still try to germinate. A popular pre-emergent here is prodiamine. A $65 jug will last most people many years.

When was the grass installed?

If installed last summer, you are fine to. Full sun ✓dense....you will get some weeds if you do nothing. You may not have to be as aggressive as if you had something else but they will pop up. Shaded, gotta watch moisture (drainage) and fungal more than others scenarios in my experience.

So you have to act now? I wouldn't be in a big hurry if u are talking about a pre.

Sod installed last August. I do have moisture issues in 2 areas. Still working on fixing that by underground drainage. I just don't want to be fighting something I can prevent before happening.

I assume at this point that it's rooted.

Pre-em's typically get put down Feb/March for summer annual weeds like crabgrass and again in Sep/Oct, however, better late than never.

You may want to read the Bermuda bible. It's not the exact same for zoysia but will still give you plenty of infomation that does appyl. https://thelawnforum.com/viewtopic.php?f=22&t=1651

I have Zeon. Get some prodiamine down. I prefer granules.

Cut it low, cut it often, and water the crap out of it. Fertilize regularly.

It doesn't like dry areas or soggy areas or shady areas. But boy does it LOVE Sun!

Check out my 2018 journal to see mine - it's really starting to perk up this last month.
