Why grow cactus seedlings in a plastic bag?

Category: Why? | Posted: Sun Sep 06, 2009 3:43 am

First time I ever tried to grow cacti from seeds was a really disaster. I ordered a kit with 12 different seeds and a germinator. I put soil in the small plastic square pots, the seeds and water. Then I waited. After a while the seeds start to germinate and I was so happy. Then after a while I noticed that some of the small seedlings just fell over and they had no roots? I spayed the pots with natural bug poison, and it crawled up a lot of larvae. It was Sciara. They destroyed nearly all of the seedlings.

The second time I where more careful and sterilize all the soil in the microwave to prevent gnat eggs. Then I put a layer of sand on top. This time it worked out fine. The only trouble this time was that I have picked out species that need different environments at different stages of their lives. Some needed fresh air and not so high humidity two days after germination. I had a real trouble to give them what they wanted and failed with a lot of them.

From now on I always grow my cactus seedlings in plastic bags. Well, it works with any closed environment; the plastic bags are just simple and cheap! Somehow the environment regulates it self in there, and you can grow as many different species as you like in different bags. I am growing messembs (Aizoaceae) in bags as well. Some species of cacti have been in a bag for two years soon (Blossfeldia). No problems with gnats or mold, and no more watering! (Well, maybe some...)

It's just perfect for the slow growing species.

Useful information Christer. You've proved that practice makes perfect!

I wonder if this technique could be tried for other plants as well...

Well sure. If it's a slow-grower it should work. I've just tried on messembs and cacti...
