What's going on with this bay tree?
My flatmate has a bay tree (outside the flat thankfully) and it's been struggling a bit recently. I turned over the leaves and found these little brown scabs? bugs? unsure!
It's light levels aren't great, but it manages fine (I moved it slightly recently so it has more light, hence 8 think why the new growth is looking better than the old), and it's watered once the soil is pretty dry.
