Barrel cactus are easily grown from seed! I picked a seed pod, took it home and made sure the seeds were dry before planting. I planted the seeds in small pots using a commercial cactus mix and in no time I had over 100 baby cactus. I have been giving them to friends like crazy. If given regular water and grown in a sunny (hot) window they grow quickly!
