They are growing all over my newly planted grass and some of them have that red center where the leaves meet like poison ivy. Can it be identified this early? Thank you for your help!

I don't know what it is, but it isn't poison ivy.

Hi. Welcome to the site. Where are you from ? You can complete the profile data so folks here can give better advice

I am not sure what seedling is that. But i think its not poison ivy. Since poison ivy will have more long elliptic cotyledon and have their three leaflets soon after the cotyledon.

Thank you! I updated my location if that helps

It looks to my old eyes like an Amaranth/Pigweed seedling.

Could be. Is the stem red?

Edited to add picture from NGA database:


The round cotyledons are characteristic, they're more elongated in pigweed.
