How can I effectively prevent and manage tomato plant mold in my garden?

To prevent and manage tomato plant mold in your garden, you can:

1. Plant tomatoes in well-drained soil and provide good air circulation.
2. Water the plants at the base to keep the leaves dry.
3. Mulch around the plants to prevent soil splashing onto the leaves.
4. Remove any infected leaves immediately and dispose of them.
5. Use fungicides as a last resort if the mold persists despite preventive measures.
