Yes sir it all makes sense.
I know all about the NPK etc. Never bothered to check my soul ph though.
Truth is, I have a "green" thumb, so I understand how most of it works. I'm just not used to killing my "weeds".
The 2,4-D is new to me, but it turns out the stuff I sprayed them with uses it. I'll hit them again in a week or so. I put down some seeds a couple weeks ago as well.
I’m terrible with plants honestly, but I got so tired of looking at a crappy yard I had to learn and that’s just the basics. Be sure to choose an herbicide based on your invasive species, same as choosing seed or fertilizer based on conditions.
Sounds to me like you’re well on your way, it just takes time now. Pre-emergent now and 3 times total this year will make a big difference next year. You’ll notice less weeds for spot treatment.
I’d do the whole yard now and then again in about 2 months just before the heat really sets in. Then wait it out until fall.
