Indoor Lime Plant
I bought a lime plant to grow inside. Some of the leaves have spots of sticky residue on them. I'm not sure what it is. The plant otherwise appears to be quite healthy and has several blossoms on it. Do I need to do anything about this?

This is typically a sign of either a scale or aphid infestation, both of which can be hard to spot. I would treat the trees for these pests. I recommend neem oil for this. It is very effective but still organic. Here is more information to help you:
