In planting a tree care must be taken to get it as deep in the ground as it was before it was taken from the nursery. If a little deeper no harm will be done.
Make the hole in which it is to be planted so large that all its roots can be spread out evenly and naturally.
Before putting it in place, go over its roots and cut off the ends of all that were severed in taking it up. Use a sharp knife in doing this, and make a clean, smooth cut. A callus will form readily if this is done, but not if the ends of the large roots are left in a ragged, mutilated condition.
SHRUBS ALONG THE DRIVEWAY
When the trees are received from the nursery they will be wrapped in moss and straw, with burlap about the roots. Do not unpack them until you are ready to plant them. If you cannot do this as soon as they are received, put them in the cellar or some other cool, shady place, and pour a pailful of water over the wrapping about the roots. Never unpack them and leave their roots exposed to the air for any length of time. If they must be unpacked before planting, cover their roots with damp moss, wet burlap, old carpet, or blankets,—anything that will protect them from the air and from drying out. But—get them into the ground as soon as possible.
When the tree is in the hole made for it, cover the roots with fine soil, and then settle this down among the roots by jarring the trunk, or by churning the tree up and down carefully. After doing this, and securing a covering for all the roots, apply a pailful or two of water to firm the soil well. I find this more effective than firming the soil with the foot, as it prevents the possibility of loose planting.
Then fill the hole with soil, and apply three or four inches of coarse manure from the barnyard to serve as a mulch. This keeps the soil moist, which is an important item, especially if the season happens to be a dry one. If barnyard manure is not obtainable, use leaves, or grass-clippings—anything that will shade the soil and retain moisture well.
