Dear PBS, Following an exceptionally wet nine months, I have Stagonospora on Habranthus magnoi and Zephryanthes spp. I completed the treatment recommended on the wiki using the bleach method and red blotches remain on bulbs and their roots. Is the solution perhaps too weak? I've soaked other bulbs (Sparaxis for one) in a 5% bleach solution without ill effects. I cannot use chemical treatments. Suggestions anyone? Very much appreciate it, Pamela Slate
