New Lawn - I.D. a weed and preparing for winter
Hi all. This is a follow up to a long post: http://forums2.gardenweb.com/forums/load/lawns/msg0816265128933.html which includes soil analysis, photos and all sorts of good advice.
I planted about September 1 and managed to get grass growing. I used a lot of water, but overall we are pleased.
First question; what is the weed shown in the photo. It is sprinkled around the yard, and it came up before the grass shoots. How can I get rid of it? Should I look at a pre-emergent in the spring? If you look at the link above, you will see the mature version. I hit the stuff with RU in the summer, but it came back.
Second question; Winter prep. I added a lot of calcitic lime and a dose of potassium sulfate about a month prior to seeding. Should I add a light application of lime now? Anything else for a new lawn?
Thanks in advance.
