Soil & Compost FAQs
What's the difference between topsoil and compost?
Topsoil is the upper layer of natural soil that contains organic matter and nutrients. Compost is fully decomposed organic material that's extremely rich in nutrients. Compost is typically used as a soil amendment rather than as a growing medium on its own.
How do I know if my garden needs compost?
If your soil is compacted, drains poorly, lacks organic matter, or your plants aren't thriving, adding compost can help. Compost improves soil structure, adds nutrients, and promotes beneficial microbial activity.
Can I use your compost for indoor plants?
Yes, but we recommend mixing it with potting soil rather than using it straight. For houseplants, a mixture of 1 part compost to 3 parts potting soil works well.
How often should I add compost to my garden?
For most gardens, adding a 1-2 inch layer of compost once a year (typically in spring or fall) is beneficial. Vegetable gardens and heavy feeders may benefit from biannual applications.
