i have a question about my irises. i planted some irises last year and didn't know that they were too deep until near the end of the growing season. the foliage had started turning yellow and they had not bloomed yet. so i researched some and replanted them an inch deep. they put out green foliage and i thought that i would get some late in the year blooms. that did not happen. so i figured that i was probably too late in the year for blooms and maybe next year. then i saw a segment on Gardening by the Yard on how to plant irises. i didn't know that half the bulb was supposed to be aboce the ground. so yesterday i went out and did that. the thing is, once the new green foliage sprouted it nevered died back during the winter. i live in alabama so somethings will take longer to die back. should i cut some of this foliage or should i leave it as is?
