For the first time in 20 years of being in the Nursery Garden Center business here in our part of Texas we moved up our Fall crops by 2 weeks on some and 1 week on others.
I judge by wind. So far this year the "winds of change" have been running a couple weeks early.
We usually change plastic on our greenhouses during the first couple weeks of October to get the correct pliability so we can get 1 more year out of a 1 year-2 year or 4 year plastic.
This year we have scheduled this for the last couple of weeks in September. We usually have 100 plus(or there abouts) temps for 120 days starting around first few days of June. This yeart was July. The trees in our forested area are loosing leaves due to heat stress a month or more earlier. Our fescue and perennial rye grasses which usually struggle and experience a 50% die back have done the best since we started planting them more than 20 years ago. Our pasture grasses have seeded a month earlier.
Usually during our summers here the "cold fronts" that bring needed rains go further east and we get nothing. This year the humidity has been up by more than 50% and have had lots more rain. Moisture here during July/August is mostly non existent. This year we have had several days of cool mornings/overcast with 1/4 inch or more of moiture. Usually its an afternoon thunderstorm and the tornado sirens go off. They haven't this year so far.
Looking and planning for a cold wet winter that lasts into Spring of 2010. If not then we will have lots of firewood for next year,,,
70-30 colder than normal based on 20+ years here working with our native north Texas area environment.
