Hi olive and others... :-)
Great efford you do there! Thank you again for spreading the love!
Since any mold etc. can quickly kill little cacti seedlings I was just wondering if anyone of you does some sort of seed treatment on your cacti seeds?
It's worse the work especially if you have harvested in the quantities you did and you want as many as possible to live!
I found that some seed batches are really contaminated and others not so much. It would be nice if most breeders would do that and tell the people, (Good selling point!?)...even tho I started sterilizing my seeds again right before sowing. The less bad microbes the better...but I'm still experimenting what the best method is in my view.
I think it would not hurt wash the seeds for about 20 min in a 1% solution of h2o2 where you could also add some alcohol or Kaliumpermanganat remove and dry them.
I guess there or other options as well and I would love to hear your methodes/option/ideas.
After drying it could also help to inoculated them with some beneficial microbes before storing. (Only a tiny amount is needed.) But the people who get the seeds do have to know this so they do not clean them again. Interesstingly some plants do carry their beneficial microbes in their seeds...but I guess cacti do not!?
Just some ideas...have a nice day folks!
