using aspirin

Question

The article talks about spraying. Can I just water the soil around the roots, or do I have to spray my tomatoes and seedlings with the mixture?

Thanks, Marcia.

Answer 1

Spraying the stems and leaves directly with the mixture will be most effective. The aspirin works by stimulating the plant's immune system and doesn't kill pathogens/pests directly, and I'm not sure whether the plant can absorb it from the soil, so the best bet is spraying directly on the plant.
