Can you start a catalpa tree from the seeds within bean?

Yes. You can start a catalpa tree from the seeds within a bean. Here are the steps involved:

Harvest the seeds: When the catalpa bean pods are ripe and brown, harvest them by cutting them off the tree. Allow them to dry completely in a warm and dry location for at least a week to break dormancy.

Extract the seeds: Once the bean pods are dry, break them open and extract the seeds. Discard any damaged or immature seeds.

Prepare the seeds: Soak the seeds in water for 24-48 hours, changing the water every few to speed up germination. Soaking the seeds helps soften the seed coat, making it easier for the seedlings to emerge.

Plant the seeds: Fill small pots or trays with a well-draining soil mix. Plant the seeds 1/2 to 1 inch deep, spacing them about 2 inches apart. Cover the seeds lightly with soil.

Provide warmth and moisture: Place the pots or trays in a warm location with temperatures between 65-75°F (18-24°C). Keep the soil moist but not soggy.

Wait for germination: Germination typically occurs within a few weeks to a few months, depending on the temperature and conditions. Keep the seedlings in a warm and sunny location until they grow few true leave stage, then gradually acclimate them to outdoor conditions.

Transplant the seedlings: Once the seedlings have developed several true leaves and have a sturdy root system, you can transplant them into larger pots or into the ground in a sunny location with well-drained soil.

Care for the young tree: Water the young tree regularly, especially during dry spells. Fertilize according to the package instructions to promote healthy growth.
