    Those are not mature, therefore, are not ready for harvest. They have to be brown and brittle. They will fall off at the touch when they mature. This does make it difficult to collect viable seed, since the wind takes them off with ease. It may be best to collect any casings on the ground near the tree.

    The next thing to consider will be you zone. Zone 9 is the very edge of what it can tolerate, heat-wise. This will mean that your mild winters will make it difficult to fully stratify them. This means very low germination rate. The refrigerator will be your best bet for at least three months.
