Mexican Key Lime is the standard lime used in beverages and key lime pie. Known by many names, this small lime is also called a Mexican Lime, Bartender's Lime, and West Indian Lime. The small, rounded, yellow-green fruit is aromatic and tart. The fruit is smaller than a Bearss lime.
A bushy, medium-sized tree that is cold sensitive and best grown in mild-winter climates. Self-fertile. Harvest fruit in Fall. Protect from cold temperatures below 32F.
Semi-Dwarf vs. Standard citrus trees:
The difference between a semi-dwarf tree and a standard tree is the mature height. Semi-dwarf citrus trees are smaller and grow to approximately two-thirds the size of a standard tree form. Depending on the position of the lower branches on the trunk, a semi-dwarf citrus can look like a bush with a short trunk, or a tree with a trunk.
The mature height of a Mexican Key Lime tree based on average growing conditions:
Semi-Dwarf tree: 8-15 ft. tall.
Standard tree: 15-20 ft. tall.
In containers, the Key Lime tree will be smaller and can easily be pruned to maintain a desired size.
The mature height and fruit production of your citrus tree will depend on several environmental factors such as climate, light, soil type, texture, fertility and moisture, and pruning practices. Your citrus tree can easily be maintained at a smaller size with annual pruning.
