I did 5 lawn renovations this spring, including my own front lawn. Results are outstanding if I say so my self on 3 of the 5.... the ones that were watered as per my directions came in thick and full, and still no summer burn. (Rye, KBG and Fescue mix seed) I used a Tupersan (siduron) based starter fert, but still had some breakthrough with the crabgrass... on my lawn I hand weed it twice a day. On the others, obvoiusly the homeowners are not as anal as I am, so they have some CB. The other two lawns that were not irrigated according to my suggested schedule came in OK, but much spottier and with more weeds. My questions are these: (And yes, I can read labels, but am looking for experienced opinions on this) My Lawn was done (dethatched, roto'd, removed 1100 lbs of sand and trash fill, added 1200 lbs of top soil and compost, seeded etc) on 5/16, the last of the 5 jobs. It's been mowed 4 times. I'd like to put down Barricade with my next (3rd) fert app, is it too soon? ( I used a second siduron/starter fert app 4 weeks ago) Lots of clover, purslane and some chickweed. Should I just live with it, or can I use a 3 way with Quicksilver now at a low rate? Hand pulling twice a day for 15 minutes is getting old.... but I don't want to destroy what so far has been a very successful renovation. I get lots if compliments on it already... great advertising, and even I have to say, it is about the best bare dirt reno I've ever seen. Sorry, but as I am new to this as a pro, I can't help but to brag a bit. I have pics but have no clue as to how to post them. So, planted in mid-May, almost 5 mowings... when can I use a pre-M and more importantly, a post-M broadleaf control? I know the common knowledge suggestion is to wait on the post emergent, but... can it be done safely now? If not now, when? Thanks in asvance!
