Hi all, I've got a 3 yr old Margaret Merrill rose which flowered beautifully the first year, didn't do much last year and this year although it's grown quite tall, has no flower buds on it at all. Has had the same treatment as my other two roses in the same bed, i.e. been pruned, mulched, fed & watered. Faces west, in clay soil,but is only 2 ft away from 6ft high box hedge behind it.
I did wonder if I pruned it too severely last year as this time it's shot up to over 5ft but looks very healthy.
