Hello, I think this may be a repeat plea from me but I had a greenhouse built on the end of a garage wall 2 years ago. The wall is covered in ivy - now inside the greenhouse. It is poorly and sad and covered in black mould (i think thats it) Have sprayed with pesticide twice and washed with washup solution(mild) three times. Looking its very worst just now, i really want to help it, can anyone help me? thank you in anticipation, Les

if 've read this right the ivy was on the outside wall of the garage and is now inside the greenhouse. It wont be happy with the conditions, the black mould will need spraying with a fungicide to 'cure it' but personally I'd remove the ivy totally.
