Colloidal silver

Definition - What does Colloidal silver mean?

In gardening, colloidal silver is used to target various types of plant pathogens, including parasites and bacteria. According to a study published in the journal of Mycobiology in March 2010, colloidal silver completely eliminated fungal infections such as Sclerotium Cepivorum in green onions. According to the study, this substance did not alter the soil’s composition or chemistry in any way.

Colloidal silver has also been shown to encourage healthier crops while killing different types of fungi. Adding this product to your plants can also boost the plant’s nutrient content. In some cases, planters can also substitute chemical fertilizers for colloidal silver. While chemical substances can hinder the absorption of minerals, vitamins and other trace elements, colloidal silver eliminates parasites without obstructing the plant’s mineral intake. Spraying a small amount of colloidal silver on fresh produce has also been shown to be safe for human consumption.

In horticulture, colloidal silver is commonly used as an ethylene inhibitor. Additionally, gardeners sometimes soak the seeds in this substance prior to burying them in the soil in order to reduce the risk of mold growth. Pre-soaking the seeds can also increase germination.
