Choosing between the many varieties of citrus trees can be confusing. There seems to be an endless selection of orange trees, grapefruit trees, dwarf lemon bushes and even limetta shrubs. But one of the most unusual and captivating tree species is without a doubt the citron citrus tree.

The citron is a slow growing and small tree with the maximum height of only 8 to 12 feet. It has stiff branches, willowy twigs and oval shaped leaves. The leaves are quite often lemon scented and are evergreen in nature. What many gardeners love most about the citron citrus tree are its large white and purple blossoms which display a brightly colored center.

The fruit of the citron tree is oblong and rather unusual in shape compared to other citrus fruits. Though there are some tree varieties which are more common than others almost all citron fruits are covered with a rough rind with a soft, sweet and watery flesh.

Some varieties of citron citrus tree include the fascinating and unique “fingered citron”, the “Corsican” variety which was introduced to the US by explorers in 1891 and etrog, diamante and Bajoura.

Though the origin of the citron citrus tree is not known for certain, it has been found to have a long and fascinating history. The earliest signs of citron harvesting were found to be in 4000 BC when excavations discovered citron seeds among other food stores and harvesting tools.

Other signs of the citron history include a Jewish coin from 136 BC which depicts a citron-like fruit on one side, a reference made by a Chinese writer in 300AD and records of the fruit being imported into Greece from Persia were it was then cultivated and enjoyed by the privileged in 200 BC.

Today citron citrus trees are found in regions around the world which have steady year-round temperatures with little chance of sudden frost or cold nights. Citrons are used quite often in cooking in places such as Guatemala, Indonesia, India and Porto Rico.

Citron citrus trees require sufficient aeration and need proper and consistent pruning to produce adequate fruit. They will also need regular fertilization, room to produce a large roots and a monitored watering system.

Here is a quick reference guide to some of the most common citrus tree pests:

Aphids: Though it is next to impossible to not have any aphids present while growing trees, they can grow in numbers rapidly and can do a lot of damage in a short amount of time. The marks left by aphids are often confused with other citrus diseases because of the dark marks which appear on the leaves. Aphids can damage a tree’s growth by sucking the sap from their leaves and causing leaves to drop and dry.

Citrus White fly: A common pest to appear on all types of citrus trees, Whiteflies are a winged insect close in size to a common fruit fly. Whiteflies will often hide on the underside of a tree’s leaves and suck the honeydew sap from the leaves veins. Similar to aphids the damage left by whiteflies is often confused with leaf rot and is similar in appearance to mould.

Orange-dog caterpillars: A large insect, orange-dog caterpillars will eat and rip the edges of a trees leaves. Though this type of caterpillar is most common in Florida it can be found on plants which have been imported and sold in other regions. The best way to rid your tree of orange-dog caterpillars is to remove them by hand. But be warned, when disturbed this species will spring two red “horns” from its head and spray a foil smelling odor.

Citrus Thrips: One of the most damaging of all citrus diseases and pests, the citrus thrip will ruin a young tree’s leaves, fruit, blossoms and roots. These persistent pests are yellow and orange in color and can usually be found on the underside of the tree’s lower leaves. The marks left by citrus thrips will be quite evident as most of the fruit, blossoms and leaves which are attacked will shrivel up and dry out completely.

Citrus Bud mite: Though bud mites can attack any type of citrus tree, they are most commonly found on lemon trees. Bud mites will appear only in hot and humid climates and will enjoy feeding on the lemon blossoms and fruit buds. To rid your plant of bud mites consider using the same all natural sprays that you would to eliminate any citrus diseases.

When caring for citrus trees it is important to have all of the appropriate tools and products. One of the best ways to stay organized is to make up your own citrus health care kits which include all of the necessary tree essentials.

If you are one of the many people who love to grow their own citrus fruit and enjoy the time, patience and commitment it takes to care for fruit bearing plants then continue reading and find out how to make your own citrus health kits.

Pruning shears: This is of course one of the most important tools to include in your citrus health kit. Proper pruning and trimming is necessary to ensure health, steady growth as well as root structure and fruit development. When preparing your kit make sure to have a pair of sharp and reliable sheers which are capable of trimming all sizes and thicknesses of branch.

Mycorrhizal Treatment: Most mycorrhizal sprays contain living fungi which when applied to soil will assist both new and mature trees to colonize their root systems and will provide excellent soil conditions. These busy little fungi will in exchange for food bring nutrients and water to the tree’s roots.

Misting hose attachment: Water is essential for citrus health and can mean the difference between fresh, unspoiled fruit and dried, useless blossoms. When building your kit consider purchasing a misting attachment for your hose which will allow for you to gently water the upper branches and leaves of your tree.

Fertilizer tablets: All citrus tree varieties will thrive when given the appropriate amount of fertilizer. The most convenient way to ensure your tree is getting enough nutrients is to use commercial fertilizer tablets. These essential citrus products are easy to use and one tablet is often enough to nourish a tree for an entire year.

And finally, the last product to include in your citrus health kit is a Biostimulant. This dry, water soluble product contains everything needed to stimulate root growth and tree strength. Most citrus tree biostimulants will include humic acid extracts, amino acids, yucca plant extracts as well as sea kelp, beneficial bacteria and living fungi.
