I need you help guys, I have planted seed of pinus pinea and now it is 1 month old. I kept it indoor for 1 week - sunny window. and then put it outdoor garden under the full sunlight (8-9 hours of sunlight). i was watering it after 2-3 days. and then I noticed that needles become brown and getting more and more brown after few days. yesterday was quite hot and I watered it and in the evening I noticed that needles become even more brown and started to fall down.
can you please advice how to save it. I want to save it very much. Please help me. Shall I water is less often? or full sunlight burnt it? I guess one of it effected really bad. or is it better to put it in just sunny window?
many thanks in advance
