How To Add Iron To Soil Beginner’s Guide

There are two best ways to learn how to add iron to soil. Much like knowing how to measure fertilizer to provide plants the nutrients they need, the soil’s quality also plays a significant role in the growth and health of your plants. The iron itself is crucial for plant growth and metabolism, so ensure that your soil can provide this. 

There are many reasons why some soils can’t provide enough iron, such as alkalinity, too much calcium in the ground, or having acid-loving plants. To remedy this, you have to amend your soil, so the plants get their iron nutrition at the recommended levels. However, it’s vital to determine the specific cause itself and conduct a soil test before choosing between the two ways below. 


How To Add Iron To Soil Beginner's Guide

How To Add Iron To Soil: 2 Easy Ways


Way #1. Iron fertilizer

The first method on how to add iron to soil is straightforward, and it’s a simple application of iron fertilizer. You can think of this as a quick remedy, especially when you notice that your plants experience yellow leaves. Remember that this could be a telltale sign of iron deficiency. 


Chelated iron vs ferrous sulfate

Amending the soil with iron fertilizer should help restore the healthy colors of your plants. Gardeners often apply at a 14-day interval depending on the label instructions. These fertilizers typically use iron chelates and ferrous sulfate, where the former is preferred because this form is readily available for plants for a more extended period. 

However, do note that soil testing is essential to know the cause of your soil’s iron deficiency. Those in the greenhouse can take advantage of easier testing because they have a definite location without many environmental changes. If you found that your soil has a high pH level, then you should choose the Fe-EDDHA fertilizer and use two pounds per 100 square feet of soil several times during the growing season. 

Of course, this treatment may vary depending on the soil and plants. Otherwise, you can also add organic matter to the soil because it is rich in natural chelates. In the next discussion below, you will also learn that organic matter like compost lowers the soil pH. 


Way #2. Lower the soil pH



As discussed earlier, soil with a high pH level is prone to being deficient in iron. Keeping this in mind, lowering the soil pH should also help amend the soil’s iron nutrition. A simple way to reduce the soil pH is by adding several amendments ranging from compost, sulfur, urea, ammonium nitrate, and ammonium sulfate. 


Acidifying the soil

You can also acidify the soil if it isn’t well buffered. This solution is limited to containers and beds because you get to replace plants frequently in these situations, and you can still incorporate amendments in the soil. The most common way to acidify the soil is by adding elemental sulfur at different rates depending on the soil type.


Signs Of Iron Deficiency

Without soil testing, it will be impossible to know that you need to add iron to the soil to make up for your plants’ deficiency. Therefore, you need to learn some signs of iron deficiency and address this problem quickly. The best way to check is by looking at the newest leaves on your plants if they are stunted and white. 

The area in between the veins also tends to turn yellow or white. Some leaves can also show chlorotic lesions. More so, it would be best if you learned what leaf chlorosis is. 

Leaf chlorosis is a symptom where the plant’s veins are green, but the leaf itself is yellow. You’ll notice the lesion starting at the tips, and besides, some plants can also experience leaf loss. The emphasis is necessary on noting that the lesions are angular and sharp because rounded lesions are signs of zinc deficiency. 


How To Prevent Iron Deficiency

It can be daunting to find out that your soil requires an amendment to provide iron to the plants at the optimal level. However, you can still correct this deficiency using the two methods discussed. You can also prevent iron deficiency altogether by simply adding sulfur when preparing the soil for your plants. 

It would also be best to know if your plants will thrive well in your soil as some species would be more susceptible to iron deficiency. For example, if you’re in Arizona, you’re better off using desert plants because they’ll grow well in Arizona soils. Otherwise, some plants may be sensitive and require soil amendments. 



It’s not enough to provide the ideal environment, such as using the greenhouse for your plants. You also have to test the soil and learn how to add iron to soil if the plants show signs of iron deficiency. The good news is that after finding the cause of the iron nutrient deficiency, you can quickly amend the soil either with iron fertilizer or other amendments that will lower the soil pH. 

Chelated iron is an ideal amendment for the soil because it is readily available for the plants. On the other hand, you can acidify the soil in your containers to lower the soil pH and solve this deficiency. The bottom line is that this problem’s remedy is straightforward as long you test your soil beforehand and determine the cause.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
