The following was received via email: I am hoping you can help me. I have planted this tree in a very large concrete container on my patio, the conditions are very good for it here - Kelowna- on the lake, sheltered from the direct sun. My question is this, do I need to fertilize this tree because it is in the container? If so what should I use, I assume I'm a little late for this, but better now than not? The leaves have come out but there are no flowers yet. Can you offer any other suggestions to help our new green friend? Thank you.
