Hi, I am newhere and was hoping to get some help. Last spring I got a bunch of Pussy Willow branches and one of them grew a root in my vase. SO I decided to try to grow a tree out of it. I planted it in the pot, fertilized and watered it generously. New sprout grew from the root and several leaves grew. It was going well until recent weeks. All of the leaves are turning yellow and drying. I keep the tree in the pot indoors, it gets plenty of light and the temp in our house is cool.
here is the pic of what the leaves look like now:
I appreciate any advice! Thank you!
