Hello Gerry

We do recommend you test your soil before selecting new plants. This will tell you whether the soil needs organic matter or nutrients, and these are easiest to work in before you plant. Also a soil test will tell you your soil pH and soil type,  and some trees and shrubs require a certain range of pH in order to thrive. Also, so e trees are better suited to clay or sandy soils.

When selecting a new tree remember to consider all the important factors— mature size of the tree, whether buildings or overhead wires will interfere, call Miss Dig if you are planting a large tree or shrub to mark underground utilities, and the amount of soil moisture and sunlight the plant will receive.

Correctly planting a new tree is critical to the tree’s long-term life. Especially important is to find the root collar so that the tree is not planted too deeply, and to provide supplemental water during dry times in the first three or four years the tree is establishing roots. Here’s a reference that explains correct planting and care, should you need it—
