Lemon and lime trees grow well in areas with mild winters. Both lemon and lime trees produce fruit in winter to late spring. According to the Florida Citrus Growers Association, all citrus fruit is high in vitamin C. Lemon and lime trees are grown as standard and dwarf varieties. Lemon and lime trees are known as "citrus". Their care and use is similar to all citrus trees. Citrus trees need good drainage and aerated soil to produce abundant fruit. Lemon and lime trees benefit from mulching.
"Eureka" is the standard full size lemon tree. "Meyer" is the smaller variety of lemon. The Eureka grows to 20 feet in height, the Meyer to 12 feet. Standard lemons have thick skin, the Meyer has thin skin. The Meyer is as juicy as the standard Eureka, but less acidic in taste. Both grow in climates with mild winters where temperatures stay above 20 F. Lemon trees bear fruit year 'round on all varieties. Both varieties have thorns on their trunks.
"Bears" is a well known lime tree variety for warm climate gardens. "Mexican" is the standard bartender's variety. These trees grow well anywhere orange trees are successful. These two standard varieties both grow to a height of 12 to 15 feet. Lime trees have thorny branches and drop many of their leaves in wintertime. The main crop matures in winter to late spring, with some fruit year round. When limes are mature, they can be as big as lemons.
General Care of Citrus Trees
Lime trees and lemon trees are evergreen trees; they are used as landscaping plants because their leaves are green all year round. Citrus trees are also grown commercially for their many varieties of fruit. Lemon and lime and all citrus trees need a warm climate to produce fruit. Choice of variety will depend on individual climate conditions.
Good soil drainage is vital for both lemon and lime tree health. Poor drainage and clay-like soil conditions are improved with the addition of peat moss, sawdust or ground bark to soil around the trunk. Trees also benefit from a 2- to 3-inch layer of mulch to preserve water. They need regular watering but should never have standing water. Water new trees twice a week in normal summer weather, more in hot times. Older trees can be watered every other week.
