Hi, I planted a new hedge photinia "red robin" against the wall at the bottom of our garden last year. Some of the plants in the corner are doing really well, but the majority of them are looking very sparse. They've lost most of their bottom leaves, the stems are quite weak and the leaves that remain are pale in colour, compared to the darker green of the thriving plants. They are growing from the top but look very bare. I've treated with vine weevil killer after spotting what I think are larvae. Will the plants come back? What am I doing wrong? The site is sunny and semi-sheltered, although it has been a very windy winter. We planted them last April so cold spring + very hot, dry summer. Thanks for any advice!
