It amazes me how many people still refuse to believe that global climate change is happening. Here in our central Texas garden, we still have eggplants and tomatos blooming, on December 8! We've only had one very light freeze so far, and for those of you who wonder, YES, that's very unusual.
This year I planted a late fall garden of mustard greens, kale, lettuces---and was planning on eating those throughout the winter. Although my bed of "cut and come again" mixed greens and radishes are doing OK, my mustards, broccoli and brussel sprouts are covered with aphids. They know a stressed plant when they see one! It's just too warm for those vegetables.
However, some of our native plants, such as the salvias, are very happy, and are producing millions of seeds. Some of those are still nice and green and blooming, too.
It's really hard to refute the idea of climate change when you can see it for yourself, not ten feet from your own back door.
Plant a garden!
