Hey guys,

Maybe a funny question asking about sprouts growing in new lawn - but we have just begin to notice there are two kinds of sprouts appearing.

The lawn seed we are using is called RTF (Rhizomatous Tall Fescue), and as far as i know... the seed was not a blend/mix - only RTF.

I have attached a couple of images showing the two different types of sprouts which are popping up. One type has a long, slender leaf - which im guessing is the RTF. The other sprout has a couple of round, thick leaves. Which im not sure what they are - hopefully not weeds.

I appreciate any help.

Cheers.
