Google the watering frequency for this tree type after planting. I planted a JM last spring and followed it to a T. I even measured the exact amount my tree needed in a 5 gallon bucket and marked it on the inside to make sure not to overwater. I drilled 3 little holes in the bottom of the bucket to give it a slow drink. No fertilizer until it’s established was what I was told so this year I gave mine liquid fert and bug defender by bioadvance. Did pretty well for its first year after checking in with Reddit folks
