I've been a fan of Nick Bantock's work since I found the Griffin and Sabine
The rituals for alraun making I'd seen instructed me to make offerings of milk, honey and blood daily. Unfortunately, this resulted in the soil getting moldy. I took the pot outside to await a chance to change out the soil and find another way of giving offering, and the cat dug it up before I had a chance.
I may or may not try another plant this year. If I do, and it fails again, I'll give up on this for the time being.
