I bought this Bloodgood maple in late August 2018 from my local nursery. It is 7 feet tall and the leaves were red when I planted in my backyard. It is facing south with morning and late afternoon sun. I fertilized it with Osmocote 15-9-12 in Spring. During summer and up until now late October and the leaves are still dark burgundy colour. Just wondering if it will ever change to red. I am located in Vancouver. Thanks for your help!
