Candytuft - leaves turning yellow
I sowed evergreen candytuft in early summer in a soil-less, well-drained medium . It has been blooming for several weeks and appeared healthy but in the last week the lower leaves on a couple of plants have started turning yellow. I haven't fertilized or changed the watering routine and the other plants in the bed are doing fine. Other beds have had fungus problems due to a wet, cold August but those problems all showed up much sooner. Anyone have suggestions? It would be much appreciated.
