I bought a 50lb bag of TTTF last year and only used half. This year I aerated and seeded the other half of the bag. I aerated and seeded on 9/26/11 and I've watered every day or every other day atleast once per day on the days I watered. Today makes 10 days. I'm seeing a few sprigs here and there. The temps for the past 10 days have been: 9/26-9/30 were highs around 84 and lows in the 60s 10/1-10/7 have been highs in the 60s but have warmed into the low 70s for the past 3 days. Lows have been between 43-49. Do you think its still early for some of the seed or do you think the seed is too old. If its too old, what should I do?
