Marmara Cambium Miner
Rose pruning continues--briefly. It poured here today for a few hours, then the sun came out, so I got outside and trimed a rose I'm thinking of removing. It's a good rose, but no fragrance, flowers are short-lived, gets huge...so I'm thinking about how much I really need it.
While I was trimming I saw some tunnels of the Marmara cambium miner. This is the larva of a moth that tunnels into the cambium layer of rose stems, leaving grey trails. Most of the damage I see from this pest is on small twiggy stuff that gets trimmed off anyway, so I don't worry about it.
It's clouding up again. More rain on the way.
