Catching up after bad sod webworm infestation

[quiet]

Here's a good starting point for guidelines:

Also check your county extension service's website. Pay attention to their watering recommmendations for your soils.

As for not applying fertilizer if it's hot . . . then when could we apply it?? (BTW, the record high at Austin-Bergstrom on February 21 is 101 set in 1996! YES, FEBRUARY 21!)

For southern turfgrasses, apply ferts when the lawn is actively growing.

You can apply Milorganite (or Houactinite- same thing, just from Houston's sewage system) any time. It won't burn. Other fertilizers, use common sense. Don't apply to a wet lawn. Water it in ASAP.

In the spring, apply fertilizers high in K to build deep strong roots. Build a thick dense turf, and you won't need much in the way of herbicides at all.

For our St. Augustineturf, we de-thatched and aerated today (big-time), followed-up by cow manure compost. After applying so much bifenthrin to thwart sod webworms a month ago, we needed to get some life back in the soil - hence cow manure compost.

Wanted to ask - when I walk the dogs I noticed a lot of lawns have either of the following 2 problems: large spots with mostly thatch and green shoots, or the entire lawn a mixture of green, yellow, and dead grass blades. Are yellow blades a root problem or iron problem?
