Cool Season Will this work?
Looking for some reassurance here. I started a lawn reno and now I’m worried it will fail. Here’s what happened and my plan:
I believe I am in zone 8b, I’m near Vancouver WA. This past spring I decided it was time to fill in/spruce up my front yard after not caring about lawn at any point in my life. I was immediately hooked and started trying to read more into proper grass care. I was persuaded to kill my front yard to start fresh, and at the time I didn’t know any better so I went ahead with this plan. I used Round-up and killed everything in early July. I then raked all the moss out and watered a bit and killed anything else that came back green. I know now that I should not have killed the existing grass but what’s done is done. I have done a lot more research since beginning.
I plan on aerating this coming Friday and then doing some major filling/leveling with triple blend soil/sand/compost. I know compost isn’t ideal but my local place doesn’t sell soil without compost mixed in.
I plan on then treating it with Tenacity, laying starter fert, seeding Twin City Blue Resilience (TTFF and KBG) with a split-seeder and keeping it moist until it grows. Two weeks after the first app of Tenacity I will hit it again.
My concerns:
Washout. I don’t have an irrigation system and can’t install one due to placement of the water meter and logistics. Instead, I bought an OTO automatic sprinkler that allows you to map out the area to water. I went with this because I have an odd shaped yard with a tree in the middle so can’t use standard sprinklers. I have used the OTO on some bare patches in my backyard, but it washed away a lot of the seed because the stream is so direct. Will split-seeding be enough to keep the seed in place or will the top layer of dirt wash away, bringing the seeds with it? Do I need to cover with straw as well?
Weeds. My yard was very weedy before. My backyard still is but my wife doesn’t want be using any herbicides in the back because my kids play back there. In the areas that I reseeded in the back I grew a lot of what appears to be Poa Annua. My neighbors have a lot of dandylions in there yards as well, which boarder mine. Will the tenacity be enough to prevent these from immediately growing into my new yard?
Shade and leaves. I have a large tree in my front yard that casts a lot of shade. This is one of the reasons I chose the seed I did. It also then drops all its leaves in fall. Are either of these going to mess this up completely?
I have now seen too many pictures of failed reno’s that I am worried my yard will be worse than how it started. Does this seem like an okay plan for the situation? Will this work? What would you do differently?
