Ferdinand Pichard gone blind
I planted a Ferdinand Pichard in the late autumn of 2015, so it's into its 2nd summer. It gave me two flowers last summer and then developed a lot of tall shoots for the rest of the year which I had to cut back.
This summer, there were more flowers (probably about 20) in June but once they were deadheaded, it produced a lot of growth but no more flowers. I checked the tip of the shoots but cannot see any buds on them. It is now over 6ft tall. It is in a mostly sunny position and the other roses in the same bed are doing well.
Would someone know whether this particular variety is prone to blindness and what I should do to make it flower? My garden is only very small and I cannot afford to keep something that does not flower.
