I found four Brugmansia arborea seeds in a desk drawer, which I forgot I had. They're about a year old, but have been in a little plastic bag, so I assume they're still viable. (Please correct me if I'm wrong though)
I tried to grow them last year and had no luck with it. They didn't root.
I didn't remove the outer seed coat though, so maybe that had something to do with it?
Anyway... I'd like some advice on how to grow these, including soil, nutrients, light level, etc.
I am literally clueless when it comes to growing, so any advice is good advice.
I hope to get better at plant cultivation with the help of this community, and hopefully by the end of the season I'll be able to give some seeds away! I'm going to grow more than B. arborea if I can get some seeds in time for planting.
