I purchased a Dreadlocks Croton a few months ago at Lowes on the markdown rack. The plant was a 3gal size with only a few leaves for $1.50. The plant has pushed lots of new leaves and is now a full bushy plant again. This plant is planted inground and in 5 hrs direct sun. Problem is all leaves are green with a few yellow blotches on a few leaves. How long will it take for this plant to regain its colors?
