Q.White, Sticky-Looking Substance
My gardenia plant is an indoor plant. It has a white, sticky substance that is on the stems and up in the cluster of leaves. Do you know what it is and how to take care of it? The plant is still blooming, but new growth look like it is being attacked, not all but some.
