I have this dwarf pine tree, say 50cm tall, it looked healthy until I decided to expose it to direct sunlight some two months ago.
For two weeks it felt like it was about to produce new stems, like I could see some new little buds on the tip of some branches. Then, all in a sudden, after couple of weeks, it lost all the needles apart of few of them on the extremity of some branches, that stayed brown.
I may have underwatered it. So, I moved it to a much less sunny area, and started water it using also a fertilizer, and after one month not only nothing grew back, but the needles left in place are still brown and dry. The fall to the ground just touching them.
I am afraid it is dead, but I know that some pine trees lose their needles once per year. What do you think?
