Summarize the following:
Using a shovel, dig a hole that is at least 20 inches (50.8 cm) deep or as deep as the container presently holding the sapling. Between these two options, choose the depth that is deeper. The width of the hole should be twice as long as the diameter of the sapling root system. Add composted cow manure and topsoil to the hole, mixing it into the soil at the bottom and sides of the hole with a shovel or garden fork. Note that organic peat moss can be used instead of topsoil, if desired. If desired, you can skip the soil amendments altogether. Doing so can make it more difficult for the tree to establish itself, but if you wish to add fertilizer to the area after planting the tree, there shouldn't be a problem. Spray the amended planting hole with a preventative "knock down" herbicide. Doing so is not strictly necessary, but it can help keep the growing area free from weeds for two years or so of growth, giving the tree enough time to establish itself in the process. Application amount can vary depending on the type of herbicide used, so follow the instructions on the label carefully. Free the sapling from its current container and place it directly into the center of the prepared planting hole. If the sapling is in a traditional nursery container, carefully tip the container on its side and grab the tree at its base. Carefully wriggle the tree back and forth until it eases out of the container. Do not disturb the roots after removing the sapling. Stand the sapling upright in the center of the planting hole. The roots should be completely beneath the soil line. Fill the remainder of the hole with soil and water well to help pack the soil in. For best results, fill half of the hole with soil, then thoroughly water this soil before proceeding. After the water appears to drain, fill the remainder of the hole with additional soil and water again. To give the tree another boost and help the sapling establish itself, consider applying a balanced fertilizer containing equal parts nitrogen, phosphorus, and potassium. These fertilizers will usually be labeled as 10-10-10, 30-30-30, or something similar. Apply 0.22 to 0.44 lb (100 to 200 g) of fertilizer per tree. You should apply the fertilizer in small pockets of soil around the perimeter of the tree. Do not spread it into the planting hole or along the surface of the ground. Surface fertilization can result in weed growth. Note that fertilization may not be needed if you mixed organic material into the planting hole prior to planting the sapling.
Dig a deep hole. Mix organic material into the hole. Apply an herbicide. Place the sapling in the planting hole. Settle the soil. Consider fertilizing the tree.
