Q&A – I sprayed aphids with an insecticidal mix. Now the leaves are black. What happened?
Question:
I sprayed aphids with an insecticidal soap/Baking soda mix. Now the leaves are black. What happened?
Answer:
The insecticidal soap probably killed the aphids. Baking soda is sodium bicarbonate. Sodium will burn foliage which is probably what happened and why the leaves are now black.
