I'm a newbie to this type of gardening but last fall I started digging out an area to create a mound to expand my banana plant gardening. I layered the bottom and worked up with layers of sticks, limbs, leaves, alternating with good draining soil and composted manure. Only thing is, I used a good bit of Castor Bean plant trimmings...stalks and leaves primarily but probably a few seed pods as well. I've been reading mixed opinions about this because they are poisonous. I'm ready to plant my young banana plants but concerned.
I honestly didn't think it would hurt the plants but now I wonder if it will kill worms ND beneficial life in the soil...?
Any conclusions based on experience?
