Early February is correct for north central Texas. Those that say March are wrong.
Easy Pre schedule for N Central Texas
Valentines Day Barricade
Memorial Day. Barricade
Labor Day Barricade + Gallery
This is great advice, The holiday schedule is actually a good schedule to go by for the avg home owner who kinda/somewhat cares about their turf. Both for pre and fert. With a couple added notes
Barricade or Stonewall as discussed many times is Prodiamine. Great grassy weed control with long soil residual. If you want to do the Holiday schedule divide the yearly max by 3 and apply on those holidays.
The downside to the Holiday schedule on Pre's is most will do the Labor and Valentines and forget the Memorial app. That's why I like two 6 month apps of Barricade/Stonewall.
And on pre's the prill mix is pretty small typically. So when their yard is 2500 sq feet on the front and they have to measure out 5lbs out of a 50lb bag and spread that small of amount. 1st. It's not that easy to spread but can be done with multiple passes on the lower settings. 2nd. They're like no way this small amount works as I just took a couple scoops out of the bag and have so much left over. Even know the bag says it will cover 13K+ or so.
