Last year I planted some Dianthus "Memories". They flowered well, but then the stems started going white and the leaves shrivelled. So i cut them back, but although they had a second flush, the flowers were rather tatty. This spring they still looked awful so I've got rid of them.
I believe they prefer chalky soil, whereas mine is clay. I have just bought some of the Gran's Favourite variety. How can i improve their chances of survival?
Thanks in advance,
