Best Fertilizer For Lemon Tree

The lemon tree is an evergreen shrub that grows in full sun. To keep it healthy and produce fruit, you need to fertilize the plant at least once a year. If you live in an area with alkaline soils, you should fertilize every other year. Fertilizing your lemon tree can be done with either a liquid or granular fertilizer, but there are important differences between the two.

Liquid fertilizers come in a concentrated form and must be diluted before being applied to the soil or watered onto the leaves. Granular forms of fertilizer are dry and must be mixed into the soil before planting. The main advantage of liquid fertilizers is their ease of application; however, they have a shorter shelf life than granular forms and may contain some chemicals that could harm plants if not applied correctly.

Best Fertilizer For Lemon Tree

To determine which type of fertilizer works best for your Lemon Tree, here are some tips to consider: Kelp, Ammonium sulfate, and Down to Earth Citrus Mix. We will also discuss why these are effective, as well as how to choose the right one for your tree. To get started, apply a small amount of these fertilizers to the roots of your Lemon Tree in spring. Your Lemon tree will thank you.

Ammonium sulfate

Ammonium sulfate is a nitrogen-rich fertilizer. Lemon trees that are young should be fertilized with 120 to 230 grams of nitrogen per year. Medium-sized trees need 600 to 1000 grams of nitrogen per year. Sprinkle ammonium sulfate within the tree’s drip line, the area where rain drops from the canopy. Do not apply manure directly to the trunk of the lemon tree.

Ammonium sulfate is available in liquid form and is easily applied to the roots. Do not apply more than one cup per tree per year. The best time to fertilize is mid-June. For second-year trees, wait until mid-June to apply fertilizer. For third-year trees, apply a pound of ammonium sulfate. For fourth-year trees, apply two pounds per tree.

Another excellent organic fertilizer is Humboldts Organics Spikes. This product contains a balanced 8-11-11 NPK ratio. It is convenient, inexpensive, and environmentally friendly. The fertilizer is designed to boost foliar growth and bloom development of citrus trees. It is not recommended for use in citrus trees if they are indoors. It is effective in both indoor and outdoor citrus trees. It is also a good choice for lemon trees.

You can also use a mulch to provide extra nutrients to the soil. Mulching adds moisture and helps to control weeds. Coffee grounds provide nitrogen and acidity to the soil, which is ideal for lemon tree growth. PH levels of the soil should be between 6.0 and 7.0 for optimal growth. Soil banks are a good choice for protection from frost and cold.

Another organic fertilizer is Ammonium sulfate. This product contains 21% nitrogen and 24% sulfur. Compared to ammonium sulfate, it requires more material per unit area. For example, 20 pounds of manure contain equivalent ammonium sulfate. Chemical fertilizers, on the other hand, are readily available and have high analysis. However, an overdose of chemical fertilizers may cause root injury and wilt.

The true lemon originated in India and later spread throughout the Mediterranean Basin. Columbus brought it to America. Two varieties of lemon are cultivated in the United States, ‘Eureka’ and ‘Lisbon’. Unlike ‘Eureka’, ‘Lisbon’ fruits are seedier and borne inside the tree canopy. The latter has a terminal bearing habit.

Down to Earth Citrus Mix

It is important to apply citrus fertilizers on a regular basis, but they should be spread only two to four inches from the trunk. You can use a 2-foot diameter ring to fertilize a tree two feet high, but you should apply a 12-inch ring if your lemon tree is over 12 feet tall. Using the proper size ring ensures that all the roots of the tree get the right amount of nutrients, and it promotes even uptake of these essential nutrients. Lastly, dry fertilizer should be soaked into the soil after being applied to the trunk, or inserted into the ground near the lemon tree using slow-release spikes.

Organic and natural, Down to Earth Citrus Mix is an ideal blend of essential nutrients for your citrus plants. This organic and natural blend contains no synthetic materials, growth hormones, or harmful chemicals. This organic citrus fertilizer will promote the growth of your tree, making it a great addition to your home garden. Not only will you enjoy a more vibrant lemon tree, but you will also have lusher, greener foliage.

When choosing a citrus fertilizer, look for a product that contains high levels of nitrogen and other essential minerals. If you find yourself too busy to regularly apply fertilizers to your citrus trees, you should consider using a slow-release fertilizer. These types of fertilizers release nutrients to the plant over a longer period of time and are perfect for those with busy lifestyles. Most slow-release fertilizers are in the form of spikes that you stick into the soil and insert into the roots of the citrus tree.

Before you begin a citrus fertilization regimen, you should conduct a soil test on the lemon tree. In addition to determining if there are missing nutrients in the soil, you can send an at-home soil test to a laboratory. Having this done will help you determine the appropriate amount of fertilizer. After all, you want to avoid damaging the tree by adding too much or too little fertilizer to the soil.

Down to Earth Citrus Mix contains natural ingredients and microbes that are important for the growth of healthy plants. This fertilizer also helps extend the time of feeding by giving the citrus plant well-balanced nutrition. You can expect the citrus plant to grow larger, with more fruit and stronger branches. Even if you have a small lemon tree, you can still use the Down to Earth Citrus Mix for optimal results.

Besides nitrogen, Down to Earth Citrus Mix has important secondary ingredients to help your citrus tree grow. This mixture contains fishbone meal, feather meal, and basalt, which aid in the protein construction of plants. In addition to nitrogen, it also contains potassium, iron, magnesium, and sulfur, which help prevent the tree from being weakened by a lack of nutrients. Moreover, this citrus fertilizer can be applied up to four times a year and can save your lemon tree from disease.


If you are thinking of growing your own lemon tree, it is best to start by using kelp as a fertilizer. This substance contains trace minerals that your lemon tree needs. Kelp is not harmful to your lemon tree, but it may be more important for potted plants because the soil in a pot depletes minerals. Fortunately, you can add sea kelp minerals directly to the leaves of your lemon tree. You can also buy Miracle-Gro Shake ‘n Feed Plant Food, a 4.5-pound container that delivers a continuous supply of food for your lemon tree.

Lemon trees need a balanced nitrogen-phosphorus-potassium ratio to survive and thrive. A good fertilizer for lemon trees should be rich in nitrogen, with twice as much of one nutrient as the other. The ideal ratio is 3:1 or 2:1. You should follow the directions on the container for proper application. You should also remember to apply the fertilizer at a regular interval throughout the year, such as in February, May, and September. Never fertilize your lemon tree during the winter months.

If you are growing your lemon tree as a hobby, you can buy a kelp supplement from a garden store. Kelp supplements are very affordable and can help your lemon tree grow healthier and more productive. Maritime is a powerful solution for citrus plants because it contains a full spectrum of micro-nutrients that your lemon tree needs. And unlike many other kelp products on the market, Maritime has an even higher concentration of key bioactive compounds.

If you are planning to grow a Meyer lemon, you should use a special fertilizer. Meyer lemon trees require a specific formula because they cannot use natural nutrients from the soil and environment. Using an organic fertilizer for your lemon tree is best because it is easy to apply and spread. The best citrus fertilizer is one that has a high nitrogen content and is slow-releasing. If you are planting your lemon tree in a pot, consider buying a container-based version.

Another method for growing lemon trees in pots is to feed them three times a year. You can feed a 3-year-old lemon tree 900 grams of kelp four to five times a year, while a five-year-old tree requires around 11 kilograms. Adding this food to your lemon tree will help it grow more quickly. However, lemon trees are notoriously finicky and can take up to fifteen years before they begin to produce fruit. For this reason, it is recommended that you give it at least 20 pounds of fertilizer every year to keep it looking healthy and happy.

Eggshells are a great source of calcium for lemon trees. Eggshells are also easy to feed your plants. Lemon trees need a high amount of trace elements and general house plant feeds often lack these important minerals. It is best to use a citrus fertilizer that has these nutrients and then add the eggshells as a supplement. If you want to use something other than the liquid form, you can also use banana peels.
