Hi Joy,

Three questions:
1. What species of grass seed did you plant?
2. What did you spray two weeks ago?
3. Did the grass come up last fall or this spring?

There are sometimes specific herbicides that you can/can't use on grass species - some will injure or kill desirable grass. Depending on what you seeded (and what came up), herbicide selection needs to be done carefully.

Yes, you can mow the flowering weeds to prevent seed and knock back the weed pressure. 

Hi, thank you for replying!

1. I don't know the specific mix of grasses, but it is a mix of warm season grasses.

2. I don't know the specific chemical. It didn't affect the grass, only the weeds. A company sprayed for us.

3. The grass germinated and started to come up last fall, but this spring it got much bigger/fuller in some areas not covered by weeds.

If we mow, do we also still need to pull up all the weeds? Or will the grass fill in and choke them out if it gets enough sunlight? Should we spray again at some point this summer/fall? 

Hi Joy,

Unfortunately, I can't help you until I know the grass species and the herbicide(s) used.

But if you seeded warm season grasses, they wouldn't really be green now - they need warmer days and we generally see significant green-up at the end of May to early June. I'm wondering if the grasses you have might be a weed, like cheatgrass? Or perhaps what was in the space before you seeded is greening up?

Can you send photos? One from a distance and several close up of the grasses.

Can you find out the mix you seeded? Call the company where you purchased it?

Please contact the company that sprayed and asked them what they used. 

It would also be great if you could provided a detailed explanation of the process you used for seeding. Then we can discuss recommendations and what you can do. My email is: <personal data hidden>

Thanks!

Hi again,

I'm not sure you saw my reply, but posting it again. Please email me photos and additional information.
