Thank you for your post Macson & Charles. I have a plot on a council run allotment site and occasionally we receive a small pile of wood chip from the Borough. Today, I thought I would add some ‘brown’ to my compost bins but didn’t know if it was a good thing to acquire new wood chip that had (shredded) ivy leaves in it. Definitely less than 10% in the overall scheme of things. It will be towards the end of 2019 when this pile of compost is ready for testing for readiness (things move slowly on Plot 14 :-)) However, I am still nervous about adding ivy to anything that will come into contact with edible plants.I’ve believed that, in general, evergreen plants have a thicker cuticle and epidermis and therefore should not be composted plus I have always thought that ivy contained poisonous alkaloids. Any thoughts or observations would be welcomed before I add any more of the ‘new’ wood chip to the engine house of plot 14.
