Answer: Newly transplanted trees and shrubs will need about one inch of water per week, applied slowly to allow it to percolate down and wet the entire root mass. If you haven't already, build a basin around your tree and water by flooding the basin. If rainfall is abundant, you won't need to water during the winter and spring months. (Keep track with an inexpensive rain gauge and supplement if rainfall equals less than one-inch per week.)
Don't fertilize until you see signs of new growth. You can then feed with a formula made especially for evergreens, applying according to label directions. Expect your spruce to take a few months to establish itself before new growth appears. Best wishes with your new tree!
