In general, trees should be planted at the same depth
(or no more than 1 inch below) they grew in the nursery.
The root system must never be subjected to freezing
or drying conditions. Trees should be spaced 15 to 16
feet apart.
To ensure good root growth after planting, water the
trees immediately after setting them out and on a weekly
basis thereafter if they receive no rainfall.
A rule of thumb is that 1 oz of actual nitrogen per
year of tree age should be applied, although this should
be adjusted according to the native fertility of the
soil and the tree's general vigor. For example, a tree
grown in a clay loam will require less applied nitrogen
than a tree grown in a sandy soil. As a note of caution,
excessive nitrogen can cause high amounts of premature
fruit drop. Occasionally, other nutrients such as phosphorus,
potassium or zinc may need to be supplied. A soil test
will be necessary to determine exact recommendations.
