Thanks for the suggestion. I haven’t had any experience with hydroculture - being a grimey soil girl. I didn’t even consider Neem Oil, but it would be perfect for this situation. I have used Neem Oil on Roses but not on any of my houseplants. Thanks again for the new perspective.

Instead of using an insecticide. Try spraying your plants thoroughly with Neem Oil. You should also spray around the base of the plant and on top of the Hydroton. Spray again in about 10 – 14 days. The mixture we use is 4ml - 6ml per litre of water and 5 - 8 drops of wetting agent. We find it applies best when we sit the sprayer in a container of hot water for a few minutes (tap water hot is sufficient) Shaking the spray bottle as we apply the Neem Oil ensuring it blends well. We’ve been using it for sometime now and have seen astonishing results.

If your plant has been sitting in the same container for the past 4 years. It would be a good idea to remove the plant (keeping it in the inner pot), give it a good rinse and clean the inside of the outer pot and water-level indicator.
