Frequently Asked Questions
What is the best soil for starting seeds?
The best seed starter soil is light, airy, and sterile, providing good drainage and moisture retention. Our DIY mix uses peat moss, vermiculite, and compost to achieve these ideal conditions for germination.
Can I use regular potting soil for seed starting?
While you can technically start seeds in regular potting soil, it's not ideal. Potting soil can be too dense, hindering root development, and may contain nutrients that are too strong for delicate seedlings.
How long does homemade seed starter soil last?
Homemade seed starter soil can last for a year or more if stored properly in a sealed container in a cool, dry place. Ensure it stays free from moisture to prevent mold or mildew.
Why is vermiculite important in seed starter soil?
Vermiculite is crucial because it helps retain moisture and nutrients while also aerating the soil. This creates a balanced environment for seeds to germinate and young roots to grow strong.
