I live in hardiness zone 8-9 (Greece - but in a cooler pocket, close to Mt. Parnitha) and have planted an Abies Koreana 3 years ago. The tree was doing very well until October this year. In fact it grew about 1.20m in this time and has made cones last year for the first time since we bought it. Now I am extremely worried. The needles are yellowing from the bottom to the top - inside to the outside - needle tip to base, non symmetric. I can not find any bugs on the tree and this years growth continues to look healthy. I do find a few spots on the trunk of the tree that bleed resin, but very little, on 2 spots it is whitish. The soil is clay which was enriched with peat and polyhum at planting. I have added since then bio-compost. The ground has a good number in earth worms. Neighboring plants are doing well - with the exception of am Pieris Japonica - which is a lighter shade of green, without the typical chlorosis symptoms (showing veins..) but a uniform "yellow". On advisement I have applied "Sequestren" and Iron pellets, as well as on advisement a leaf fertilizer "Miller Nutri leaf" 20-20-20 which I also sprayed on the Abies and all other plants and conifers. They all seem to do very well with it. At this time the conifers had already previously received their own specialized fertilizer. On advisement I have applied a root drench and foliar spray against "Phytophtora" - but I have seen so far no result. Will I loose my tree? Could it be water shortage in the deep earth as I watered, but we had hardly any rain at all this year? Thank you so very much for your answer. PS I can provide pictures of the tree.
