I've posted last year about my young Whitebeam tree which is not thriving. I decided to give it another year to see whether things would improve but if anything it looks more sparse and the leaves are falling even earlier. I've regularly fed and watered it. Could there be anything else causing these problems? It's in alkaline soil - not great quality but have added lots of manure and compost to the border over the last few years and other plants are thriving there.
It's mainly to provide privacy from a neighbours window and I don't know whether to bite the bullet and replace this tree with something else? It's barely grown at all and I need something to grow fast and bushy in this border asap!
Any advice? TIA
