After the sorus is collected and brought back to your facility it needs to be prepared for spore release by cutting the reproductive material away from the rest of the blade and cleaning it. Blade material brought in from the wild presents a contamination vector for the rest of your nursery operations. Carefully clean the blades in an area of your facility that is easy to clean and separate from other cultures. There have been many published methods of cleaning sorus material; below, we chose the method that works best for our facility and we find the most effective.

Sorus tissue is ready to be released on the day after sorus preparation. Generally, the sorus preparation, release, and seeding will each take a whole afternoon and will be completed much faster with an extra set of hands.
