When should I fertilize a lemon tree?

Fruiting trees are one of God’s greatest gifts to mankind. Which other creation can provide us with our basic needs like the fresh air that we breathe, delicious and nutritious fruit that we can eat, and wood we can turn into shelter or burn for fuel? I can’t think of any plant more useful than a fruiting tree.

Lemon Lime Tree

Of the many fruiting trees out there Lime and Lemon trees are my favorites. Lemon Lime trees are ornamental trees with glossy, evergreen foliage and tiny white blooms that are present almost all year round. It is always exciting when the Lemon and Lime trees begin to grow fragrant blooms and colorful fruit, both of which emit a refreshing citrus scent.

There are many types of Lemon/Lime trees you can plant at home. There is the shrub-like dwarf Improved Meyer Lemon Tree that produces sweet, juicy fruit that is less acidic and less bitter than other Lemon Lime trees. The Improved Meyer Dwarf Lemon Tree can be grown outdoors in USDA plant hardiness zones 8 to 11, but may also be planted in a pot for those who live in USDA planting zones 4-8.

Another wonderful cultivar for home growers is the dwarf Eureka Lemon tree that will give you a constant supply of zesty lemons at any time of the year. When you buy a dwarf Eureka Lemon tree for sale you will be glad to find out that the tree is nearly thornless so you do not have to worry about getting pricked by sharp thorns when you are harvesting juicy and tangy lemon fruit.

Bearss Lemon tree is another nearly thornless variety that produces seedless Bearss Lemons with a distinct aroma and unique flavor of blended lime and lemon without the bitterness and acidity you usually get when juicing lemons and limes.   

If you want the best of both worlds but have limited space at home, then the Cocktail Tree Lemon Lime is the best cultivar for you. The Lemon Lime Cocktail Tree gives you both lemon and lime fruit from a single tree made possible by grafting both Key Lime and Meyer Lemon scions onto a single compatible rootstock.

Fertilizing Lime and Lemon Tree

It is a fact that a Lime Lemon tree should be planted in well-draining soil and it needs enough sunlight and proper watering to be healthy. However, one other important part of caring for the Lemon Lime fruit tree is providing it with balanced nutrients from fertilizers.

Fertilizers are fed to Lemon Lime hybrid trees for it to become healthier, more productive, and more beautiful. Most soil does not provide sufficient nutrients to fruiting trees like the dwarf Lemon Lime tree hybrid. Nutrition is necessary for optimum Lemon Tree growth. Remember that as trees grow, make leaves, produce blooms, and develop fruit, they consume lots of nutrients from the soil. When we apply fertilizers, we replenish the lost nutrients and make sure that there will be enough food for our Hybrid Lemon Lime tree to flourish. The primary nutrients needed by Lemon Lime hybrids and other citrus trees are Carbon Dioxide in the air, hydrogen in the water, oxygen from air and water, nitrogen, phosphorus, and potassium. Secondary nutrients that should also be fed to our Cocktail Lemon tree are calcium, magnesium, and sulfur.

Outdoor trees should be fertilized with complete citrus food once in January or February. The next application of citrus fertilizer should be in April or May, with the last application to be done in August or September. Make sure to follow the label directions to maximize the usage of the citrus fertilizer you will apply.  

Lemon Tree Diseases and Treatment

When not properly cared for, Citrus trees like the Lemon and Lime tree in one, become prone to diseases like black sooty mold caused by the spread of aphids, citrus canker, and other fungal infection. Most diseases can be prevented by employing proper gardening hygiene and the application of copper-based fungicide.
