Yellow Leaves On My Meyers Lemons Are Caused By Nitrogen Deficiency!

The reason why my lemons have turned yellow is because I am using too much fertilizer. When I add too much fertilizer to my lemon trees, they get too big and then they rot before their time. If you want your lemons to grow into beautiful fruit, it’s very important that you don’t over fertilize them with any kind of fertilizer. Too much fertilizer will cause your lemons to become too large and may even kill them if they’re not cared for properly.

When you use too much fertilizer on your lemon trees, you’ll end up with yellow leaves instead of green ones. You can see that my lemons are now turning yellow from the excess nitrogen in the soil.

I’m sure you’ve heard of the term “nitrogen toxicity” before. It refers to when plants or animals are affected by excessive amounts of nitrogen in the soil. Plants and animals that are suffering from nitrogen toxicity will die within a short period of time due to lack of nutrients. It’s important to note that there is no such thing as too much nitrogen in the soil, but rather too little nitrogen in the soil.

Your lemon tree may also have yellow leaves if the soil pH is too high or too low. The ideal soil pH for lemon trees is between 6 and 7. Soil with a pH that is either too acidic or too alkaline can cause yellow leaves on your lemons, as well as a bevy of other problems. To fix this problem, water your lemon tree with aspirin water to lower the soil’s pH. To water your lemon tree with aspirin water, dissolve two aspirins in a gallon of water.

Next, pour the aspirin water into a watering can and water your plant liberally. Wait a few days to see if your lemons start turning green again.

Another reason why your lemons might have yellow leaves is due to the air pollution in your area. If you live near a freeway or other large road, chances are the air quality isn’t very good. Poor air quality causes a lot of problems for plants. Some of these problems include yellow leaves, as well as curling, browning, or yellow spots on the leaves. To determine if the air pollution is causing your lemon tree to have yellow leaves, try planting it in a different area of your yard that is further away from any major road.

Test The Soil For Nitrogen, pH, and Other Nutrients With Your City’s Local Gardening Website!

If you want to test your soil for nutrients such as magnesium, potassium, and nitrogen, you can use your city’s gardening website. Most major cities have a gardening website with guides on how to plant different types of flowers and vegetables in your specific area. To find yours, simply perform a search using the key words “gardening websites” along with the name of your city. After visiting your city’s gardening website, search for the types of plants you want to grow (in this case, lemon trees) to find instructions on how to properly care for them.

Once you’ve found the instructions, scroll down until you find a list of recommended tests. These tests will allow you to determine whether or not your soil has sufficient amounts of certain nutrients that support the growth of your lemon tree, such as magnesium, nitrogen, and phosphorous. In addition, you may also find other helpful information such as the ideal temperature for growing lemon trees and how much water your plant needs. Some websites will even have a special tool that will allow you to input the make up of your soil in order to calculate the nutrient levels of your current soil.

Test the Soil For Macro Nutrients, pH, and Micro Nutrients With a Subscription!

If you want to go beyond the basic tests that most city gardening websites offer, you can get a soil test done through your local Cooperative Extension office or through a professional testing lab. These more in-depth tests will allow you to determine whether or not you have sufficient amounts of macro nutrients (like nitrogen, phosphorous, and potassium), micro nutrients (like copper, magnesium, and iron), as well as the pH of your soil. These tests typically take a few days to a week, but they are fairly inexpensive and may offer you a lot of useful information to help your lemon tree, as well as any other plants that you decide to grow in the future.

Determine Whether or Not You Should Use Fertilizers On Your Soil

The next step involves testing your soil for the nutrient that it is currently lacking. In order to do this, you will need to refer back to your city’s gardening website in order to determine which tests to run.

You will also need to acquire the materials needed to run these tests. Most tests require some sort of soil sample, as well as water and a few other common household items. To collect a soil sample, simply take a shovel and dig up a small portion of your soil. Try not to dig up any rocks or pieces of debris, as this will throw off the test results. After you have collected a representative sample, put the soil in a bucket.

When your soil sample has been collected, it’s time to run the tests. Each test is fairly simple, you simply mix a certain amount of water and a few other ingredients in a bucket and then mix in your soil sample. From there, the testing jar needs to be placed somewhere relatively warm for the specified amount of time in order for the reaction to take place. After that, you will have to interpret the results based on the guidelines provided by your city’s gardening website or another reliable source.

After you have run all of your tests, you will finally be able to determine whether or not your soil is lacking in certain nutrients. If it is, you will be able to use the list of nutrient rich fertilizers offered by your city’s gardening website to find the right kind of fertilizer to add to your soil. In addition, these websites typically offer guidelines on how and when to apply the required amount of fertilizer.

If your soil is lacking in a nutrient, you should immediately apply fertilizer to your soil and re-test it again in a month in order to make sure that it has had the desired effect.

If you would like to have a more automated and professional system for testing the health of your soil, you will need to purchase a packaged test from a gardening store or online retailer. These packaged tests are fairly reliable and offer immediate results. In addition, some of these packages come with instructions on how to apply the right amount of fertilizer to your soil, if necessary.

Another option is to use a service like the one offered by Rescue Rooter Labs, which will send you a soil test kit in the mail along with instructions for collecting your soil sample, sending the sample to the lab, and interpreting the results. The price for this service is on a per-sample basis, and the cost of each sample depends on how many variables you test for. This option might be a better investment in the long run, as it is likely to give you more accurate results than testing your soil yourself from home.

There are a few different online retailers that sell home soil test kits. The following are three of the most popular:

Appendix B: Common Nutrients and the Plants That They Benefit

After sampling your soil and running the necessary tests, you should have a good understanding of whether or not your plants are getting all of the necessary nutrients. If they aren’t, you may need to add fertilizer to your soil in order to correct this issue. This appendix explains the benefits of various nutrients, so that you will know which ones to look for.

Nitrogen (N) : Often considered the most important nutrient, nitrogen is mainly responsible for photosynthesis in plants, which is necessary for growth. Nitrogen also promotes the production of chlorophyll and enzymes. Legumes and grasses often benefit from extra nitrogen, as do plants growing in soil that is low in this nutrient, such as sand.

Phosphorous (P) : Another important nutrient, phosphorous is often found in deposits alongside nitrogen. It is necessary for plants that grow quickly, such as corn and beans, and it helps support the overall health of a plant.

Potassium (K) : An important component of all cells, potassium is necessary for the overall growth and development of plants. It helps fight off disease and promotes healthy leaves and stems. It is especially important for flowering plants to have adequate amounts of potassium.

Calcium (CA) : Used in the development of cell walls and the metabolism of plants, calcium is vital for a plant’s overall health. It works in combination with magnesium and other nutrients to promote strong cell walls.

Magnesium (MG) : Another element that is necessary for the metabolism of a plant, it also works in combination with other elements to support the growth of healthy cells. It helps keep the stems, leaves, and roots strong.

Sequestered Nutrients:

These nutrients are often found in soil that has been over-farmed, or in soil with poor quality. These nutrients are less likely to kill a plant than the other types of unavailable nutrients, but they can still impede its growth and overall health.

The best way to deal with these nutrients is to add them when you amend your soil, so that they become assimilated into the soil.

Sulfur (S) : Sulfur is mainly used by plants in the development of proteins. It is most often found in soil that has been over-farmed, as it is a common element in certain types of crops.

Trace Elements:

These elements are not necessarily crucial for plant growth, but they still help the plant in a minor way. Their effects can often be seen in the health and vigor of the plant. The trace elements often found in soil are:

Boron (B) : Promotes chlorophyll production and helps plants to grow. Boron is often found in acidic soils, such as those found in pine forests.

Copper (Cu) : Responsible for the production of oxygen in plants and helps them to fight off disease.

Iodine (I) : Necessary for photosynthesis.

Iron (FE) : Necessary for the creation of chlorophyll and the production of ATP. It is common in clay soils.

Manganese (MN) : Responsible for producing carbohydrates and is often used by legumes to create nodules for nitrogen fixation.

Molybdenum (MO) : A catalyst involved in various chemical reactions within the plant.

Zinc (ZN) : An enzyme activator that helps with seed germination and photosynthesis.

The main goal when amending your soil is to create the perfect growing environment for your plants. Most plants need more than one type of nutrient to thrive, so always amend your soil to suit the needs of each individual plant rather than using one blanket method for all of them.

When it comes to nitrogen, most plants need plenty of it. It is found in most types of soil, but if you need to add more you can purchase nitrogen-rich materials like blood meal, or even fish and animal manures.

These types of materials are not always readily available though, so a good alternative is to use your garbage. Composting your food waste is a great way to naturally enrich your soil with nitrogen and other nutrients.

You can sometimes get away with not adding nitrogen at all if you are growing plants that need less of it, like lettuce. Most plants need a balanced amount of it though, so adding some type of nitrogen-rich material to the soil is almost always necessary whenever you are growing plants.

Soil Structure

The soil structure is just as important as the nutrients and air pockets within it. Having a good soil structure allows for better air flow within the root zone of the plant. It also allows for water to flow through the soil, hence preventing water from pooling around the base of your plant. Pooling water can cause the roots to rot. It also prevents good air flow, which is important because plants need oxygen.

When adding amendments to your soil, you also need to ensure that you are not making the soil too dense. Most amendments like sand and compost are lightweight, so they won’t often cause a problem. Things like peat moss and vermiculite, however, can sometimes make the soil denser. When this happens, you need to add something lighter to the soil to counter the effects, like perlite.

When it comes to ensuring that your soil has good structure, there is a simple process you can go through to ensure success. First of all, you need to examine your soil.

Does it fall together when you grab a handful?

If so, it probably has good structure. If it doesn’t, you need to add some type of material to the soil to help with structure.

When you find the perfect material, you should then mix in an amount that will ensure the soil is loose enough around the roots, but still dense enough that it doesn’t fall apart when you grab a handful. As with most things in gardening, there are always exceptions. Certain plants prefer soil that is on the denser or looser side, so you will have to do a little research about the plant you are growing before finalizing your soil mixture.

It is important to note that soil structure is not just important for ensuring that your plants get the right air and water flow; it also helps protect your plants from disease and pest attacks. Having a soil that is too loose can expose your plants’ roots to disease and pests, so make sure you don’t go too light on the mixing.


Some people believe that fertilizing your lemon tree will help it grow green leaves. Unfortunately, this is not the case. While it is true that fertilizing will help your plant grow in general (by providing nutrients), it will not change the color of your leaves.

So in conclusion, your lemon tree will not grow green leaves. Actually, unless you live somewhere in a polluted area (like near a freeway) or the air is heavily polluted in some way, you shouldn’t need to do anything special to ensure that your tree gets the right amount of light.
