Rowan tree looking sickly
My Rowan tree was planted 2 years ago. This season it started out looking healthy with lots of blossom and then lots of berries. Over the last week or so the leaves are yellowing and although it’s still hanging on to its berries it doesn’t look too good . I have another planted at the same time that is still lovely and green . I have watered and mulched both trees the same . Any advice would be welcomed . Thanks Jane .
