|i am a novice gardener. a couple months ago, i planted 2 rhodedendrums. they are each about 2 feet in size. they are planted about 6 feet apart, and they experience the same amounts of sun/shade/water, etc. they are in the shade most of the day, with a few hours of full sun in the afternoon. immediately after planting, they both really started to look great with lots of new growth. however, about 2 weeks ago, one started to look bad with leaves hanging down and falling off. the other rhodedendrum is still looking really great. since there are no signs of insect problems, i have been advised that it sounds like insufficient water, but why would one plant look bad and the other look great? i've increased the amount of water but it doesn't seem to be helping. the only other action i've taken is applying scott's plant food for rhodedndrums. any other suggestions?
