Something spooked your Mom, obviously. Talk to your step-dad and see if he knows what happened. But I'm willing to bet she had some kind of close call! If you grow, do it away from home. Plant the sprouted seeds the day before it is supposed to rain, say a prayer over them, and walk away for 6 weeks. DON"T make visiting them a habit! You get noticed regularly going out into the woods and you will get busted.
