Catching up after bad sod webworm infestation

In late September, a majority of our front lawn (St. Augustine) was wiped out by a terrible sod webworm infestation. After treating with bifenthrin (topical) and Bayer Complete (systemic) one month later to stop their cycle, the recovery back to a thick turf is much slower because it is cooler now.

Is there anything you would recommend in terms of N-P-K ratios or certain products that could stimulate growth during the cooler season to achieve a thick turf in a short time period?

Cooler Nights and shorter hours of sunlight this time of year sure put St Augustine in a Semi Dormant state. Recovery can be real slow. Ground temperature because of Cooler nights is a big factor.

Try Milorganite, and apply it heavy. It helps hold moisture as well as a slow stead feed for about 6 weeks. You can't apply too much unless you dump on and cover the turf.

That's great advice from Ric, but be patient. Turf has really slowed down here in TX, and will come to a halt in the next couple of weeks. If you're south of a line from Corpus Christi to Laredo, you may see a response, but otherwise, it's real close to "bed time" for lawns in TX.

St. Aug can hang on to it's green color (but not the vibrant green) during the winter, but with the cool nights and shorter days growth pretty much stops after Thanksgiving.

In the winter, we're a lot drier than Florida. The very dry air heats and cools quickly. After Thanksgiving, we routinely get hard freezes at night here in TX, with wild temperature swings during the days. It's not uncommon for us to get down into the 20's at night and warm into the 70's during the day.

But a good dose of sewage sludge now will pay dividends in the spring. Hit it with a 1-0-1 ratio fert at green-up.

I am South of Brownsville Texas and on the Gulf. Even here St Augustine grows so slow in the winter we might only cut it once a month and then only to get the high spots near the warm roads or buildings. Many years Crab Grass doesn't die out

I only wished I could be on full time vacation in Mexico. But I was talking about my location in Florida compared to Texas. I do get out of town on occasion for some fun. But at my age I am becoming more of a home body.

Here's a good starting point for guidelines:

http://aggie-turf.tamu.edu/

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.
