Plants Forbidden For Compost?
The thread on "Help on a couple of questions please" has inspired me to post these questions:
(1) What plants (and fungi, etc.) should never be used (or only sparingly used) for food crop compost due to their poisonous, toxic or otherwise unhealthy nature when the food is consumed?
(2) What plants (and fungi, etc.) should never be used (or only sparingly used) for any compost due to toxic effects on the plants that you wish to grow with the help of the compost?
P.S. Regarding question (2), I have already heard that Walnut, Ailanthus and Norway Maple all have alleopathic properties but I am sure there are other plants of concern or open to debate.
