We nicked the cala seeds with sandpaper like you said last Tuesday in chat, flowox, and 3 out of 6 of them have sprouted this morning!
These babies are my son's science project. They're doing a controlled experiment with fertilizers.
Thanks for your help. And thankyou too Bon for the seeds. I'll let you both know how they grow.
flowox and bon
You are very welcome :o)
