Q: For the past two or three summers, I've noticed the leaves of maple trees around Fargo are a pale yellow color rather than deep green. Similarly, my 20-year-old autumn blaze maple also has pale yellow leaves in the spring and summer. There is little or no color change in the fall. We long for the fall days when we have bright red leaves. We've tried root treatments, which are only partially successful. Do you have any other suggestions to keep our tree alive? — Todd Dudgeon, Fargo.
What's a gardener to do? Most of us fill our available yard space with our favorite flower and vegetable varieties that have bloomed beautifully and yielded well in the past. But seed catalogs and garden centers are filled with new varieties each year. Should we throw caution to the wind and try new varieties or stick with the old favorites? What if new varieties are duds? Will the season be wasted on ugly flowers and non-productive vegetables?
