Hello all. When I bought this Juniper, there seemed to be a touch of brown tips in the foliage underneath. That seems to have disappeared. Tonight I used Bioadvance 3 in 1 spray on it due to a bit of fungus I discovered. I noticed a bit of brown tips on top. Not sure if it resulted from the spray or if I just noticed it then. I just wasn’t sure if I could use the concentrate version in a normal spray bottle, and was reassured it was okay. Could this be the issue, or something else? Also the question I really need answered, will fixing this necessarily require a defoliation measure?
