Q.Linden tree in distress
My Linden tree was planted last October. The leaves came on great and dense this spring, but now at the end of May the leaves closest to the trunk are turning yellow, their autumn color, and falling off. Is this normal? Does it need water or fertilizer? We had a wet April/early May, but it has not rained for 10 days or so. There is mulch around the base. It gets plenty of sun.
Linden trees need moisture, with good drainage. And mulch. Because it's a fairly young tree, it also would appreciate some fertilizer. This article may help you:
