Hello,
I went to visit my grandmother today, she was upset that one of her plants/flower is not growing. I looked at it and some of the lower branches/shoots are dead and dry. The tips of the new growth are turning black and welting. She stated that the plants growth this year is stunted. I am not a garden guy, but really wanted to help her out for she does not use the net.
Here are some pictures attached. Two of them are of the plant in question and one is an offspring from the same plant without the issue.
Any help or advice would be great!
Cheers
