[Arisaema-l] What Happened To My Seedlings

[Aad van Beek]

Peter,

I never seen to learn it. At least the spelling is correct this time corms instead of corns. In all other post I used tubers when referring to arisaema's so this must be a slip of the pen.

Why doesn't everyone write and reads Dutch than life would be much easier for me.

>> When I sawed the arisaema seeds in Mai last year I used 7 cm (3 inch) square containers The soil was 50% regular potting mix, 20% pumice, 20% course sand and 20% perlite. Filled the containers with the potting mix up to 1,5 cm (0.6 inch) under the top. Made the soil soaking wet. Put all the seeds from 1 packet on it (these seeds were soaked in water for about a week, refreshed it ones). Put about 1 cm (0.4 inch) quartz sand on top and finally sprinkled it with a fine layer of grid. Then put a refrigerator bag over the container and to secure the bag put them in a second container like this

>> After 3 weeks I checked twice a week if there were any leaves visible. If they were about 1 cm above the ground I removed the plastic bag and put the container outside in a shady place. There they stood until september / october when I harvested all corms. Half of them are now in the refrigerator to see if the two cycle in one season will work out for me and the others half I will place in march in containers again.
