### Why Wood Ash Works for Tomatoes
Wood ash, the powdery residue left after burning untreated wood, is packed with **potassium, calcium, and trace minerals**. Potassium plays a key role in flower and fruit development, while calcium strengthens plant cell walls, preventing diseases like blossom end rot.
**Benefits of using wood ash for tomato plants:**
1. **Encourages more flowers and fruit** – Potassium triggers more frequent blooming.
2. **Prevents calcium deficiency** – Reduces the risk of blossom end rot.
3. **Improves flavor** – Enhances the sweetness and overall taste of tomatoes.
4. **Repels pests naturally** – Acts as a mild deterrent against slugs and some insects.
