San Pedro Cactus from seed....not working.
I've never tried to grow a cactus from seed. I sowed 1 seed each into 9 small peat pots. I used a mixture of vermiculite and milled sphagnum (sp?) moss.
I put these in a flat, covered with a plastic dome, on a seedling mat. Humidity was never a problem.
Now, 4 weeks later I only got one sprout out of 9.
Did I do anything wrong? I read these were easy to grow.
Also, is there ever any possibility of flowering in zone 4?
