i picked up a few catalpa seed pods last fall and am wondering if anyone has experience germinating them? the pods have been sitting in the garage since.

These seeds are very easy to grow. The pods should be gathered when they are brown, but before they split open. The seeds need to be held over the winter in a cold (ambient) location, and kept fairly dry. In the spring the pods should have split open to release about 100 or so small light seeds. The seeds just need to be placed about 1/4" deep in potting soil and kept moist; they usually germinate in about 3 weeks. I have always had a very high germination rate, nearly 100%. (not my writing but a snippet from below).
