Long, hot, dry summer in here Central TX. Was still in the 90's up until 6 days ago. 1" of rain in the last 2-1/2 months. All of a sudden, 3 nights in the 30's this week, with highs only in the low 70's . . . delightful! But now, all of a sudden, some Tif 419 lawns are going dormant already. One month early! Last round (5 of 5) of fertilizing was done last week of Sept. Andersons 25-5-15 1.96% Amm N 12.42% WSN (urea) 4.37% WIN 6.25% Other water soluble N (methylene ureas) Ammonium Phosphate Potassium Sulfate 5.1% Sulfur Good micro pkg: Cu, Fe, Mn, Zn Thought I'd get another month. The shorter cut lawns (1.75" to 2.00") - are still green, but the higher cut lawns (2.25" to 2.5") are starting to lose color. Many neighboring lawns have lost almost all their green during the last couple of days.
