Compost is a mixture of organic matter that has been broken down by microorganisms. It is an excellent source of nutrients and beneficial microorganisms. Compost can also improve soil structure and water-holding capacity. However, compost can be variable in quality, and it may contain weed seeds or pathogens.
Manure is a source of nitrogen and other nutrients. It can improve soil structure and water-holding capacity. However, manure can be variable in quality and may contain pathogens or weed seeds. It should be composted before use to reduce the risk of contamination.
Volcanic glass, also known as perlite, is a lightweight, porous material that is often used in seed starting mixes. It improves drainage and aeration and does not break down over time. Volcanic glass is a renewable resource and is not harmful to the environment.
Garden lime is often added to seed starting mixes to adjust the pH. It is made from crushed limestone and can raise the pH of acidic soils. However, garden lime should be used with caution, as too much can harm plants and beneficial microorganisms.
In conclusion, there are many different ingredients that can be used to create a seed starting mix, each with their own benefits and drawbacks. By understanding the properties of these ingredients, you can create a mix that is tailored to the needs of your plants.
Benefits of Using Seed Starting Mix
Seed starting mix is an essential component for successful seed germination. It is lighter and more porous than regular garden soil, which makes it easier for young plants to grow roots and absorb water and nutrients. Here are some of the benefits of using seed starting mix:
