The USDA drought monitor site is important for gardeners. I scooted my browser over there when I saw migrating spring birds back in the Carolinas early, on Jan 6th. Did they know something we did not?
And there you have it. If this keeps up, winter wheat in the midwest will not do well; we grow white winter wheat in SC and it may not be a banner crop here, either. The Mississppi River may well again run low, interfering with deep draft barge traffic. Southern states east of the Appalachian Mountains are in drought - especially Georgia. Most of Texas is hurting.
Drought resiant seeds and breeds, mulching, drip irrigation, and wicking beds are looking like better and better options for gardeners. And rain barrels are sounding pretty good. It was 80 degrees at the Columbia SC airport today. In January. This does not bode well for the summer heat.
