Clematis 'The President & 'Niobe"
We bought two Clematis from crocus in 2 ltr pots. They are both planted in terracota pots, we folowed the planting instructions and feed on clematis feed fortnigntly.
The president has developed discolouration on the lower leaves, whilst the leaves furthest away are healthy. Niobe leaves are mostly healthy, just an odd dark discoloration.
Any suggestions? Please help. Pictures attached.
