Hardiness determines the extent to which a plant or tree can tolerate cold or heat. Normally this is measured in cold such as "plant hardiness to 27 degrees." This means that below 27 degrees the plant will begin to be effected by the cold, starting with freezing of leaves and or fruit.

All of these trees require full sun and well-drained, deeply fertile soil. The hardiness zones and spacing vary depending on the variety of tree. They all require a soil pH between 6.0 and 6.5 except the orange tree which requires a lower pH.

In horticulture dwarfing is considered a desirable characteristic in modern orchards, where genetic dwarfs may be selected and propagated, or more often, scions are grafted on to dwarfing rootstocks. Almost all modern apples in commercial use are propagated as dwarf or semi-dwarf trees for ease of picking and spraying, and higher productivity per unit of land.

Rodents, especially voles, tend to feed on tree bark when other sources of food are exhausted or difficult to come by. Sometimes they will eat a band of bark encircling the trunk of the tree, and if this happens, the tree will die.
It also helps to pick up dropped fruit and mow around the trees during the summer, so that rodents are not attracted to the orchard.

You can use any fruit for this, but it is probably easiest to find multiple varieties of apples. Apples are available in many countries all year round. If you are teaching this honor to a group, buy one apple per person, getting as many varieties as you can. Then cut each apple into slices, and place them on plates. Label each plate with the name of the apple variety it holds. Then have a taste testing party.
