Those who enjoy gardening and growing indoor plants need to learn how to sterilize potting soil to destroy all the bugs and pathogens.
Sterilized and clean soil will do a lot of good for your plants. Using the same potting soil repeatedly can lead to a buildup of fungal spores, weed seeds, harmful pathogens, and garden pests. If you opt to reuse the same soil instead of replenishing it, it would be best to sterilize it often. This leaves you with clean uncontaminated growing soil for your plants.
Why Should You Sterilize Potting Soil?
Sterilizing potting soil is very important! Soil contains harmful bacteria, pathogens, and fungi that harms or kills the plants. Insects and larvae may also be present causing harm to plants. Store-bought soil that claims to be sterilized cannot be trusted. It may be contaminated through bag punctures, mishandling, shelf life, or other elements.
How to Sterilize Potting Soil
Sterilizing your potting soil is easy and beneficial to plants. You only need a few household items and about 45 minutes to complete the process.
Prepare your soil for sterilization. The soil must be moist enough to be able to compact into a ball. But it should crumble when pressure is removed. This is done by packing a ball of soil between your hands and adding a little water. Mix until you get the right consistency.
Place the soil into the roasting pan or baking sheet. Evenly distribute it in the pan and break any soil lumps available. Keep the soil under 4 inches deep and do not fill the edges of the pan. Cover the pan or sheet tightly with a foil. The foil must be tight and secure to prevent moisture loss and the soil burns. Make a hole in the center of the foil large enough for the meat thermometer to fit in through it.
Start the sterilization process. Set the oven at a low temperature and Place the tray inside. The temperature for sterilization should be 180 degrees Fahrenheit. Temperatures above this may cause burning. Burning the soil changes the chemical composition of the soil. The burnt soil will cause harm to plants. Allow the soil to burn for about 30 minutes at a steady temperature. You must pay close attention to temperature fluctuation to avoid using too high or too low heat.
Cool your use before using it. After baking for 30 minutes, remove the soil from the oven and let it sit until it reaches room temperature. To allow heat to escape, carefully lift the corner of the foil. Be very careful as you do this as the escaping steam will be very hot and can cause burns.
Use your soil. Once the soil has cooled down and removed from the pan, go ahead and place it in the pot. Remember to sterilize your growing pots too so that they do not infect the new soil. Plant your seeds no deeper than 4 times the diameter of the seed. Water the sterilized soil with a mister to avoid flooding it. Place the soil and the sown seeds into a cool room, avoid direct sunlight until germination.
Conclusion
Sterilizing potting soil indoors will bring a repulsive odor that is awful and smells earthy. Some people can tolerate it while others cannot and might be allergic to the odor. Before sterilizing your soil, open your windows and turn on a fan. The odor will not linger for long if the indoor air is circulating with the outdoor fresh air.
FAQs
What shouldn’t use to sterilize soil?
I’ve tried bleach, I used a little bleach to clean up some moldy soil (which had been sitting in a bag for a long time) and then put it in my garden, and it seemed fine. I used one cup of bleach in three gallons of water. It smelled like rotten eggs for a couple days and I had to throw out all of my plants. I would never use bleach again.
I’ve tried soaking it in ammonia, but it didn’t do much. But I don’t think it’s necessary or recommended.
What does work?
The easiest way to sterilize soil is to use a heat gun. This is actually a form of pasteurization, which is much faster than using steam or steam heat. The pasteurization process takes about 3 minutes to achieve a kill of all bacteria, while it would take days for a slow-acting sterilant like ethylene oxide to kill all of them. So, you can kill 99% of the bacteria in 3 minutes. It can be used to kill all kinds of bacteria and fungi. You can also use chemicals, which are usually toxic and will kill the organisms that you want to keep. The most common chemicals for this are chlorinated hydrocarbons. They have a low toxicity and are easy to use. A third option is to use physical methods such as digging up the soil and moving it to another location. Rubbing alcohol can be used as a disinfectant and also as a solvent to get rid of stubborn soil-based disease. Make sure you do not use it in any area with soil that has been previously treated with a fungicide, as it will react with the active ingredient and make the soil unusable. Hydrogen peroxide is another option. A better option would be to use an autoclave, which is a pressurized chamber that kills bacteria, viruses, fungi, and other pathogens.
Why sterilize soil?
Soil contains living organisms.
These organisms include bacteria, fungi, mites, nematodes, protozoa, and viruses. The presence of these organisms in soil is often considered undesirable. For instance, bacteria can cause disease or spoilage in food products.
What’s the kind of mold that I should be worried about?
I’m not sure if you’re aware, but there are two types of mold: “black” and “white”. Black mold is toxic and may cause illness. White mold is not. You can easily tell the difference by looking at the mold, it will be white for “healthy” mold. If the mold is black, it’s probably toxic and you should throw it away.

In the past decade, high-quality horticultural coconut coir has become popular as a growing medium for greenhouses and hydroponics farmers.
If you love gardening or hydroponics, now is the time to consider using coco coir for your plants. The correct pronunciation or coir is coy-er according to the Cambridge dictionary.
What Is Coconut Coir?
Coir is the fibrous husk and dust that make up the outer layer of a ripe coconut. This part is least seen as it is removed before the fruits arrive in the market. But it is available as a soilless growing medium.
Coconut coir is common in India and Sri Lanka. These are areas where the Cocos Nucifera coconut palm grows in plenty. The growing medium can either work alone or mixed with another material. This material is perlite.
Why Use Coconut Coir?
In hydroponics and pot gardening, coir is a substitute for peat moss. It is a renewable resource with a more neutral pH. It helps manage the nutrients in the hydroponics systems. Coir decomposes slower than peat moss releasing its nutrients in a slow economic way. This is one of the greatest benefits of using coir in hydroponics because the nutrient solution has a huge impact on growing success.
Types Of Coco Coir
Every time you buy coconut coir, you are buying three types mixed – the fiber, pith, and coco chips. These three together provide a powerful growing medium very healthy to plant growth.
Coco pith or coco peat is the fine ground coconut or pear moss. It’s absorbent and fine with small particles. It must age well before it goes to the farm.
Coco fiber is not very absorbent and adds air pockets into the growing medium. These air pockets provide oxygen to the root zone. This fiber breaks down fast with the air pockets decreasing over time.
Coco chips are a hybrid between the coco fiber and coco peat. They are large pieces that create air pockets and absorb the water well. It helps keep your plants well hydrated.
The coconut coir must be a mixture of these three types to achieve the best results.
CANNA is one of the top coconut coir providers. This company monitors the production of their coir to ensure it is well dried, aged, and flushed of all salts. They package their coir in 40L expandable bricks. You will have to rehydrate the medium after receiving it.
Fox is also a top coir provider. Just like CANNA they track their product to ensure it is well dried, flushed out salts, and aged before packaging it. FOXFARM packages their product in a 2 cu ft. expanded bag.
COCOTEK consists of all three types of compressed media. It has low levels of sodium and one of the best for first-time growers. This is a cheaper option compared to CANNA and FOX FARM. It is packaged in 5kgs with a decent mix of coco fibers and pith.
Coconut coir, also known as coco coir, is a natural material that can be used in a variety of ways. It is made up of the fibres of coconut shells and is used in many different industries, including in agriculture, horticulture, and forestry. For example, coconut coir is used as a soil amendment to improve soil structure and nutrient levels. This helps to create fertile soil and increases crop yield.
It’s a natural and organic alternative to plastic mulch, which can be harmful to both plants and animals. Coconut coir is made from the stalks of the coconut palm tree. It’s a renewable resource that is naturally occurring in tropical climates.
The production of coconut coir is highly labour intensive, as the coconut fibres need to be removed from the coconut shell before they can be processed into coconut coir. The majority of coconut coir is produced in India and Indonesia. In recent years, production has increased significantly, with India alone producing about 80,000 tonnes of coconut coir per year. Coconut coir is primarily used in agricultural applications such as soil amendment and organic fertiliser. It is also used in horticultural applications such as garden mulch, ornamental plant pots, and as a growing medium for houseplants. It is also used in forestry applications such as tree planting, and it is commonly known as coconut fibre or coco fibre. Coconut coir benefits The benefits of coconut coir are numerous. Nutrients Coconut coir is an excellent source of potassium, magnesium, phosphorous, and calcium.
How is it used?
The stalks are cut, dried and shredded into fine pieces. The shredded coconut is then mixed with water to create a thick, clay-like mixture. This mixture is then spread over the ground as mulch to help with soil building, prevent weeds and retain moisture.
Why Is Coconut Coir So Great?
It is considered to be a highly efficient organic growing medium, which improves soil quality and reduces the need for chemicals. The fibres have many beneficial uses in horticulture, including as a mulch and for growing houseplants.
The main benefits of using coconut coir for plants include:
improving soil structure, reducing disease, improving water retention, reducing weed growth, reducing the need for chemical fertilisers, enhancing the appearance of plants, increased yields and pest control.
Coconut coir can be used to make a wide range of different products and there are many ways to use it. It is a very versatile material, so you can easily adapt its uses for whatever purpose you wish.
Are there different types of coconut coir?
Coconut coir is actually a byproduct of coconut oil processing. It’s similar to chaff or straw, and can be used as mulch or composted.
There are many different types of coconut coir, and most of them are made from the husks of mature coconuts. Coconut husk is a material that has been used for centuries in making a variety of products.
Conclusion
Whether you choose to use this media in hydroponic or in containers, by itself or mixed with other media, the coconut coir works magic. It plays a key role in providing an ideal growing environment for your plants.

Undoubtedly, the best mycorrhizal products play an important role in plant growth-enhancing the roots, which are a major part of plant development. These fungi help enhance the soil! Which in return provides the roots with better access to air (oxygen) and water.
Mycorrhizal fungi are common in all types of soil where plants grow. They grow a large root network throughout the soil and associate with the root system to create a greater association with plants.
Mycorrhizal fungi do not plant roots. They behave similarly to plant roots. Like roots, they burrow into the soil to collect nutrients and water for the plants. To sustain the fungi, the plants’ leaves send sugars to them as food.
Given that this excellent association is natural adding more mycorrhizal fungi to the soil is essential. These beneficial fungi occur naturally in the soil, but you must introduce them to the seedlings in the hydroponic systems or starter plugs.
Types of the Best Mycorrhizal Products
There are two groups of mycorrhizal fungi – ectomycorrhizal and endomycorrhizal fungi.
The Ectomycorrhizal Fungus
This fungus develops on the exterior of the root cells. Ectomycorrhizae are found in natural environments, mainly in trees or forest ecosystems. They form visible reproductive mushroom-like structures at the feet of the trees they inhabit. This fungus grows between root cells without penetrating them. It is symbiotic with spruces, pines, and most hardwood trees like oak, willow, and beech.
The Endomycorrhizal Fungus
This fungus penetrates plant cells where direct metabolic exchanges occur. It colonizes shrubs and most herbaceous plants without forming visible structures. In the endomycorrhizal fungi class, arbuscular mycorrhizal is the most prevalent in soils. Its name comes from the structures it forms in the plant root cell: the arbuscular. Arbuscules are finely branched root structures. They form within a cell and serve as a metabolic exchange between the fungus and the plant.
Other types of mycorrhizal fungi only exist in nature and are given to specific families of plants. These types are unavailable in commercial products; you can only get them in nature. They include the Orchids, Ericoid, and Arbutoid (the ericaceous family).
Mykos mycorrhizal is an organic and natural fungus. It creates a sponge-like mass highly beneficial to the soil. It helps it collect and store water and nutrients while increasing both intakes. This fungus is a species of the arbuscular mycorrhizal fungi class.
Mykos is a fast-growing beneficial fungus that does not contain any other microbes like the ectomycorrhizae of Trichoderma. This fungus breaks down, cycles, and retains nutrients. It also provides a front-line defense against ecological stresses. Once administered, Mykos will continue to grow and become an extension of the roots. It does this while administering better sustainability and efficiency. The larger and healthier the root system, the more yields the plants produce.
Pros
It helps new plants absorb transplanting shock
Stimulates new root growth
Increases root mass, resulting in more nutrients and moisture absorption
Transports nutrients over large distances and delivers them directly into the root cell
Protects your plants from heat stress and drought
It keeps harmful pathogens from reaching the roots
Improves soil structure of sandy and clay soil
Creates strong roots fast
Cons
Individual plants can connect with other plants through the mycorrhizal network. Even where it’s unwanted, it connects and shares nutrients, water, and sugars.

What Plants Need Mycorrhizal Fungi?
Several plants benefit from mycorrhizal fungi. These include:
Trees
Oak, pine, and spruce tree species can benefit from mycorrhizal fungi. It can help them extract nutrients and water from the ground by fusing with their roots.
Shrubs
Blueberry, rhododendron, and azalea shrubs are some of those that benefit from this fungi. It can help shrubs obtain more root power and increase their tolerance to environmental stresses.
Vegetable Crops
Carrots, peppers, onions, potatoes, and herbs can benefit from mycorrhizal fungi. It can help increase vegetable resistance against diseases and ensure they get more nutrients from the soil.
Is Mycorrhizal Fungi The Same as Rooting Hormone?
Mycorrhizal fungi and rooting hormones are two different things. However, both can be used to help plants thrive.
Rooting hormones are applied to the cut ends of plants. It helps them develop roots more quickly. You can use a rooting hormone to increase your success rate when propagating plants. Contrarily, mycorrhizal fungi are applied to the soil around the plant roots. It helps plants absorb water and nutrients and withstand drought and disease.
Where Can I Buy Mycorrhizal Fungi Near Me?
There are several places you can buy mycorrhizal fungi. Here are some suggestions:
Local Garden Centers
Nurseries and garden centers carry a variety of gardening supplies. Most stock mycorrhizal fungi. You can visit a garden center near you and ask the staff if mycorrhizal fungi are available for purchase.
Online Retailers
Many online retailers specialize in gardening supplies. Others stock it as part of their general inventory. You can search for retailers near you or those that deliver in your area.
Specialty Stores
You may find mycorrhizal fungi for sale at specialty stores focusing on organic or sustainable gardening supplies. These stores may be more likely to carry a variety of products, including mycorrhizal fungi.
Manufacturers
Going directly to manufacturers is another option. You might find one that sells to the public. Many companies that produce mycorrhizal fungi have websites that allow you to purchase their products online.
How Often Should I Apply Mycorrhizal Fungi?
Many factors influence how often you’ll need to apply mycorrhizal fungi to your soil. Here are a few things to keep in mind:
Follow The Manufacturer’s Instructions
You should also look at the specific instructions provided by the product manufacturer. These instructions will provide the most accurate guidance on how often to apply the mycorrhizal fungi.
Apply Mycorrhizal Fungi at Planting Time
Mycorrhizal fungi are typically most effective when applied to young plants or at the time of planting. This allows the fungi to establish a relationship with the plant’s roots and help the plant absorb water and nutrients more efficiently.
Reapply Mycorrhizal Fungi As Needed
If you use mycorrhizal fungi to help establish new plants or improve plant health, you may need to reapply the product regularly. The specific frequency will depend on the needs of your plants and the particular product you are using.
What Can I Use Instead of Mycorrhizal Fungi?
If you do not want to use mycorrhizal fungi or can not find any, you can use compost, fertilizers, or animal manure. These alternatives can provide many benefits to your plants. However, they may not benefit your plants as mycorrhizal fungi can. You should determine your specific needs and choose an alternative based thereon.
What Eats Mycorrhizal Fungi?
Mycorrhizal fungi can be damaged or destroyed. You should avoid chemical pesticides and limit physical disturbances. Excessive moisture or dryness can also damage the fungi. Taking steps to protect and preserve the mycorrhizal fungi in your soil will help ensure that it benefits your plants.
How to Breed Mycorrhizal Fungi
Breeding mycorrhizal fungi can be a complex process that requires specialized knowledge and expertise. If you are interested in breeding these fungi, I suggest seeking guidance from a professional in the field. Alternatively, you can keep these steps in mind:
The first step in breeding mycorrhizal fungi is to isolate individual strains. You can do this by using surface sterilization or culturing techniques.
Once you have isolated particular strains, you can select specific traits. Good traits include their ability to colonize the roots of individual plant species or withstand certain environmental conditions.
Next, you need to cross-breed your selected strains to create new fungi with the desired traits.
You should test the resulting mycorrhizal fungi strains to ensure their effectiveness.
If your resulting strains are effective, you can mass-produce them for personal use or sale.
Conclusion
Roots are very important to a plant. They anchor the plant in place, resisting the forces of nature like wind and running water. They take in oxygen, water, and nutrients from the soil for the plant to bloom. Roots are also good for the soil! When it rains, the roots hold the soil in place so that it is not washed away. Healthy roots mean healthy soils and healthy plants as well! Now you know an affordable way to grow a healthy root structure that will cause your plants to thrive! Go ahead and excel in your farming!

Advantages of Adding Sulfur Powder to The Soil
This fantastic powder has many health benefits for the soil. They include:
Lowering the soil pH value. The best soil pH ranges from 5.8 to 7.0. Some soils, especially in the limestone regions, may have a high pH of about 8.0 with 50% lime. Such soils lack essential minerals like iron, manganese, and zinc. The leafy plants growing in such soils may become yellow due to deficiencies. Adding sulfur powder to the soil solves these problems.
It is a great fungicide. This powder controls fungus and mildew on leaves. It is best known to prevent mold, especially when applied before the fungus settles on the leaves. It works best when used on dry leaves.
It is best used as a pesticide. Sulfur powder is one of the oldest, best-known pesticides. It is best used in vegetables and fruits. It controls thrips and spider mites. One has to wear a protective mask when applying this powder.
It offers essential nutrients to plants. Sulfur carries essential plant nutrients that include, Potassium, Nitrogen, and Phosphorous. It also improves the soil and assists in fixing phosphorous and nitrogen.
Used as a snake repellant – Snakes do not like the smell of sulfur powder. It is one of the best repellants for your outdoor surroundings without killing them.
Used as an insect repellant on pets. Rubbing sulfur powder on pets eliminates chiggers, ticks, and other pests.

Where Do Plants Get Sulfur From?
Sulfur is an essential micronutrient for the growth and development of plants. It is mostly absorbed by plants as sulfate from the soil. It is then translocated to plastids in the leaves, where it is then assimilated into organic products,
Sulfur plays a vital role in plant photosynthesis, respiration, and the formation of cell membrane structures. It originates from rocks and minerals released by water weathering, temperature changes, and chemical reactions. When exposed to air, sulfur combines with oxygen to form sulfate which is the form that is available to plants.
Sulfur is stored in raw organic material and humus in most soils. Microorganisms in the soil work to decompose this organic matter, and in the process, the organic sulfur is converted to sulfate, the form in which plants can absorb it.
Does Epsom Salt Add Sulfur to Soil?
Epsom salt is magnesium sulfate, meaning it contains a form of sulfur.
It is essential for plants as it helps their seeds germinate, makes the plants grow bushier, and produces more flowers. It can also help to improve chlorophyll production and deter insects and pests such as slugs and voles. Epsom salt may be a great addition to conventional fertilizer as it can supplement vital nutrients.
The best way to use Epsom salt is to drench the soil with 1 tablespoon of Epsom salt solution for 1 gallon of water. Apply this solution to the soil after seeding to help keep the sulfur levels in the soil up.
Another way to apply sulfur to the soil through Epsom salts is by sprinkling a cup on a seeded bed. This will significantly benefit your plants.
Epsom salts also have the added benefit of adding another nutrient to the soil: magnesium. This can give your plants a boost, but it should only be used when there are deficiencies in the soil.
How Long Does it Take For Sulfur to Lower Soil pH?
One of the cheapest ways to lower the pH of the soil is to add sulfur. Bacteria in the soil transform sulfur into sulfuric acid, which reduces the soil pH.
The application rate needs to be reduced by 2 points to about 2000 lb per square acre area.
Using sulfur to lower soil pH is a slow process so large pH changes are unlikely to happen quickly. It may take up to years to see a noticeable change.
A pH change may take about 2 to 3 months for a smaller area. Make sure you get the best quality Epsom salts to achieve this. Add sulfur this year to lower the pH for the following year or the next growing season. This will give the sulfur and bacteria in the soil enough time to react and produce their required results.
When Do You Apply Sulfur to Soil?
A spring application of sulfur usually works best. It is during this season that you will have the highest activity of bacteria that will transform sulfur to sulphuric acid, which will help lower the pH
Because this is such a slow process, you may have to repeat the application over the years to get the best results.
What Should Sulfur Levels Be in Soil?
The critical limit of sulfur in the soil is approximately 7-15 ppm. Anything below this range may hamper plant growth and production.

FAQs
How do you add sulfur powder to soil?
Sulfur (S) is an important mineral that’s often added to the soil. You can add it directly, or if you’re working with a large volume of soil, you can add it as a liquid or powder and then mix in the soil.
You don’t need to add sulfur to the soil, but you can use it as a fertilizer. It is sold as a dry powder for use in garden and flower beds, and you mix it with water and water-soluble fertilizers to create a water-soluble product. It will be available at your local garden center or nursery.
If you need to add sulfur to your soil, you need to find a source of elemental sulfur, or hydrogen sulfide.
Sulfur is applied to the soil as a component of a sulfur-based fertilization program. The amount of sulfur applied to soil is determined by the type of soil and climate you are growing in.
What is sulfur good for?
Sulfur is a key ingredient of soil. It helps plants to absorb nutrients, and it also improves soil structure. Sulfur is found in many different sources such as soil, compost, gypsum, wood ash, seaweed, sulphate of lime, sulphate of magnesia and gypsum.
Sulfur is an essential nutrient for plant growth and development. Plants require sulfate for the synthesis of many important compounds, such as amino acids, fatty acids, proteins, nucleic acids, chlorophyll, and vitamins.
Sulfur is a mineral that can be added to your garden. It will increase the number of healthy plants and decrease the number of sick plants.
If you are trying to boost your soil’s fertility, adding sulfur to your soil is an important step. Sulfur is a key component of the process that converts atmospheric nitrogen into plant-available nitrogen.
Where can you buy powdered sulfur?
Powdered sulfur is sold in chemical supply stores. It’s usually labeled “sulfur”, “sulfate” or “S”. The “powder” part of the label means it’s fine, and not a coarse rock powder. I’ve seen it in a couple of different grades, but I’d suggest the cheapest one that still gets the job done.
You can use elemental sulfur (sulfuric acid) or sodium sulfate. These are sold in garden centers as “plant food”, or as “plant food pellets” (I have not seen them for sale under any other name). They are very cheap and easy to use.
How much sulfur should I add to my soil?
Plants have different needs for sulfur, and you need to test the soil in your garden and add the proper amount. There are different ways to measure sulfur. The most common way is to use the sulfate of potash method. This involves mixing up a little water with the soil.
Sulfur is found in all soils but its availability is low because most plants cannot use it. Sulfur is also very mobile and can be carried out of the soil by water.
