Growing Instructions for the Northern Catalpa

The seeds have a period of dormancy. They can be planted in the fall for spring germination or they can be cold stratified to simulate winter conditions and to break their dormancy. The seeds are stored in a refrigerator so they have already been stratified. 1. Place the seeds in a plastic bag and seal it. Store the bag in a refrigerator for 3 weeks. 2. Fill a pot with a mixture of potting soil and sand, peat moss or vermiculite. The seeds need moist, well-drained soil. Use pots that have drainage holes in the bottom. 3. Sow the seeds on the soil and cover them with a thin layer of soil. 4. Water the container and leave it to drain. 5. Put the pot in a warm, sunny area. 6. Water the pot regularly so that the soil is moist but not wet. 7. The seedlings can be transplanted when they are a few inches tall.
