I received a letter from my HOA telling me that I needed to prune some dead leaves and limbs from my plants. I called and spoke to the community manager, and I explained to her that it was not a good idea to prune frost sensitive plants until the threat of frost was over. She got a little "huffy" with me on the phone. Anyway, she agreed that I could disregard the letter and touch base with her in a month about this issue. I want to follow up with a letter to the board to acknowledge that I spoke to someone, and I would like to include some references that give some details on proper pruning. It could be a website or a title of a publication. Does anyone have any recommendations? Thanks.
