I planted 250 plump, healthy Dutch iris bulbs last October in full sun, in well-drained fertile soil, at the proper planting depth. (I have hundreds of thriving bulbs and rhizomes, including German, Siberian, and reticulata irises). Only about 20 Dutch irises have bloomed this spring. I didn't witness any squirrels eating these bulbs, but they are probably the culprit. My garden has no other 4-legged pests. Would someone please confirm whether squirrels like Dutch iris bulbs? They eat my crocuses and some tulips like candy...!
Thanks Mitch. I might try again this fall, since the Dutch iris bulbs are affordable. This time, I'll dip the bulbs in some hot pepper, vinegar and garlic sauce before planting, to see if that discourages the little thieves!
