Colorado—the word means “red” in Spanish. And Colorado’s soils are often reddish, due to the abundance of oxidized iron. Here in Colorado Springs, Garden of the Gods (right) attracts visitors with bright orange sandstone monoliths. Further north, Red Rocks Park and Amphitheatre is part of the same formation. Our well water has so much iron in it that our white laundry turned pink—we had to install an iron-removal component to our water system.
So, with all this iron present in our soils, why do so many plants here suffer from a deficiency?






My houseplants had been looking fine all summer, but now they were obviously ailing. No leaves were drooping, no obvious critters were chomping on the leaves. It was more of a general sense of decline—and a dappled, grayish pallor to the foliage.
If you feed them, they will come. Anyone who puts sunflower seeds into a birdfeeder sooner or later has to contend with squirrels. And if you grow a garden—well, squirrels like many of the same foods we do, plus flowers, tulip bulbs, and numerous other plants. The question isn’t whether or not you’ll have squirrels in your yard. You will. The question is, what are you going to do about them?
