Step #2. Submersion

Once you’ve cleaned the sand, you’ll want to give it one more rinse or soak in hot water. In order to completely submerge the sand, pour boiling hot water into the bucket. Submerge the object for a few minutes before draining the water and re-immersing the object three or four more times.

As soon as you’re done using hot water to clean the sand, you must rinse it with water a second time. Even while it seems like a lot of labor, the goal is to have clean sand that can be seen through crystal-clear water after washing. After that, you can remove as much water from the sand as you like.

Step #3. Drying

When you’ve completed the first two processes, you’ll be left with sand that is moist. For drying, use a towel to remove all moisture. In order to achieve optimal sterilization results, spread the dried sand out thinly on a baking sheet.

Sterilizing potting soil by steaming it for at least 30 minutes or until it reaches 180 degrees Fahrenheit is considered the best method (82 C.). Without a pressure cooker, steaming can be done easily and quickly. The pressure cooker should be filled with several glasses of water, and a few shallow pans of flat soil should be placed on top of the rack. Foil should be used to cover each pan. After 15 to 30 minutes of heating at 10 pounds of pressure, the lid should be closed and the steam valve should be opened just enough to enable the steam to escape.

When utilizing high pressure to sterilize nitrate-rich soil or manure, you should always exercise extreme caution, as this mixture has the potential to explode. For those who don’t have a pressure cooker, fill the sterilizing container with approximately an inch (2.5 cm) of water and place the soil-filled pans (covered with foil) on a rack over the water. Keep it open just enough to minimize pressure buildup while bringing to a boil. Allow it to continue to boil for 30 minutes after the steam has been released. Remove the dirt after it has had time to cool (for both methods). Until you’re ready to use it, leave the foil in place.

Sterilizing Soil with an Oven

Sterilize soil in the oven as well. Using a glass or metal baking pan, cover the dirt with foil and place it in the oven for around 4 inches (10 cm). Using an oven thermometer set to 180-200 degrees F (82-93 degrees C), bake for at least 30 minutes, or until the soil temperature reaches 180 degrees F. (82 C.). Beyond that point, poisons can begin to form. Remove the food from the oven and allow it to cool before removing the foil.

Sterilizing Soil with a Microwave

The microwave can also be used to sterilize soil. Fill microwave-safe containers with moist soil, preferably quart-sized ones with lids (no foil). Add a few vents to the top of the pot. For every couple pounds of dirt, heat the soil 90 seconds on full power for 90 seconds. Larger microwaves typically have enough room for many containers. Allow these to cool before using by covering the vent holes with tape. You can also put 2 pounds of moist soil in a polypropylene bag and seal it. Ventilation is important when using a microwave, so leave the top open while cooking. 2 to 2 and a half minutes at full power for heating the soil (650 watt oven). Allow it to cool before removing the bag.

Conclusion

If you want to use sand in your garden or greenhouse, there is an important step that you must take. If you don’t know how to properly sterilize sand for plants, you run the risk of exposing them to disease-causing germs and microbes. With the help of common home materials, you can accomplish this in just three simple steps.

The first step is to thoroughly rinse your sand in a bucket of water, and then thoroughly swirl the mixture until the water is no longer dark. The next step is to bring some water to a boil and use it in the same way. The water should be clear when the sand has been re-submerged in the hot water.
