Rhododendron leaves dark green and deformed
This year I decided to take up gardening as a hobby. I've really enjoyed it so far, planting blueberry bushes in the backyard (faces south) and rhododendrons between my sidewalk and porch. The leaves of my Rhodies (some of the leaves) are dark green and deformed, curling. They didn't die and fall off, but I removed them today since I was afraid of what leaving them on might do. Right now, I water with a soaker hose every three days for 15 minutes, with the hose looping around and back to the start. I kicked back the watering to that after reading that 75% of purchases die to overwatering. I'm in North Alabama and in zone 7a. Anyone seen this before?
