I Have A Chinese Dogwood Tree (which Is An Evergreen) I Bought It 5 Years Ago And It Was About 9 Feet Tall. It’s Now 15 Feet Ta

Question

ll and the first year it’s produced flowers. Every spring i have hundreds of leaves with the tips turning brown and the leaves turning yellow and falling. The tree looks very healthy otherwise. New leaves are coming out while lots of the old ones are falling. I did spray this year and last year for anthracnose and no help. Any ideas?

Answer 1

Check your growing conditions. It also would be prudent to have the soil tested. They need an acidic soil and yours may be alkaline.
