The ideal temperature for growth of oranges (for example) is between 21☌ and 32☌. Generally growth occurs within a temperature range of 13☌ to 38☌, depending upon the species and cultivar being grown. While a citrus may survive a period of cold, it does need warmer temperatures yo grow and fruit. It is important to recognise the cold tolerance of citrus varies, as do other cultural requirements. More tender species may not perform well or at all in colder areas, unless in a greenhouse, but lemons, oranges, grapefruit and cumquats are grown successfully in places where outside temperatures can reach zero over winter, sometimes with a little protection if the cold gets extreme. Most citrus are considered subtropical plants, but some can be grown in colder climates. LESSON 1 INTRODUCTION: SCOPE, NATURE, BOTANY AND TAXONOMY
