Many factors other than winter low temperatures can affect plant adaptation, including soil fertility and drainage, spring frost, summer heat and humidity, length of growing season, pest and disease pressures, and microclimates.

When choosing fruit varieties to plant, good resources for local fruit growing information and ideas include area retail nurseries, agricultural universities, county cooperative extension offices and Master Gardener programs.
