Determining If a Plant Is Self-Pollinating

Self-pollination varies by species. Many tomatoes, peppers, and beans are self-fertile; squash, cucumbers, and fruit trees often require cross-pollination. To know for a specific plant:

• Check seed catalogs or extension publications.
• Observe flower structure: perfect flowers (both stamens and pistil) often self-pollinate.
• Bag a flower before opening; if it sets fruit, it’s self-fertile.

Without knowing the plant, a definitive answer isn’t possible. Provide the species for specific guidance.
