A couple questions:
I have a couple of Castor Beans that look great, as we've not had a frost yet. Does anyone know, or can anyone point to a reference, that details how long/if the poison in the plants remains in the soil? I know the seeds are the most poisonous part of the plant, but the stems/leaves (and presumably roots) are as well. If I put the whole thing in the compost pile, will it poison the compost?
It also occurred to me that the hot, sunny spot I planted them in would be ideal for tomatoes next year. If there is any poison left behind by the castor bean, will the tomatoes absorb it, or just have their growth stunted?
Anyone know the answer to these questions?
Scott, remove takeout to reply, of course
