Middlesex, United Kingdom
I planted a short hedge of photinia for my neighbour two summers ago to make a division between our two driveways. The line of shrubs has grown very well and become lovely and bushy with light pruning. Everything appeared to be going well but this winter red spots have appeared on many leaves, some quite heavily spotted. The leaves have all stayed on the plants and there is a super collection of buds of new growth. I believe this is a fungal disease and may have been caused because the plant reacted against our long spells of wet weather. I sprayed with a fungicide about a month ago and repeated it a few days ago. My question is ...does the plant normally recover with this treatment or will the leaves probably always have this problem. Any advice of any kind would be welcome.
