|i have several golden showers draecenas. They have been dropping so many leaves that some braches are almost bate. I see sticky shiny spots on the leaves. i have sprayed with Volck Oil and a spray for mites/pests/fungi.They are in pots on my porch. What could have gotten to them?( the leaves turned yellow with brown spots and parts of the stems died.)

|The sticky substance you're finding on the leaves indicate your dracaenas have developed a population of insect pests. Scale insects and mealybugs are common on dracaenas and can be controlled with Insecticidal soap sprays (or you can dab individual insects with a cotton swab dipped in rubbing alcohol). I'm concerned that the Volck Oil may have left a residue on the leaves that is suffocating them and causing them to drop from your plant. Instead of using the oil, try treating the insects with insecticidal soap sprays. There's enough fatty acids in the insecticidal soap to suffocate the pests but not enough to damage the leaves of your plants. I hope your dracaenas recover!
