I bought this little cherry tree on the internet this summer but when the tree came it had just a few leaves. The next week the leaves had like an orange color and it started loosing leaves. That's why I decided to change the soil because it was normal dirt without a lot of drainage and spraying with an organic antimold. And now the soil has akadama and pumice. I thought it was too warm outside in summer so decided to put it inside next to a window pointing south. Since then the new little leaves died before they get big. There is just one big leaf but it's sick. I live in Germany so it's kinda cold now outside around 5° in the morning. What can I do? What is the disease that my cherry tree has?
