Comparison: Best Black Gold Compost Blend (Updated | Nov 11th)

Consider the volume of planting space you need to fill; an 8‑quart bag is ideal for small containers or indoor pots, while the 16‑quart packs are better for larger beds or multiple containers. Larger packs often provide a lower cost per cubic foot, but make sure you have a dry storage area to keep excess soil fresh. If you garden seasonally, buying a 2‑pack of 8‑quart bags can be more convenient for staggered use.

The Earthworm Castings Blend (8 QT) is enriched with a higher proportion of screened earthworm castings, which boost microbial activity and nutrient availability. The standard All‑Organic mix includes a balanced blend of peat moss, compost, perlite, and pumice for aeration and moisture retention. Choose the castings blend if you want a nutrient‑dense starter for high‑yield vegetables or fruiting plants.

Yes, the Black Gold All‑Organic Potting Soil is OMRI‑listed, meaning it meets strict organic standards approved for use in certified organic production. This certification assures you that the soil contains no synthetic fertilizers or pesticides, which is important for organic gardeners and for maintaining soil health. It also helps you stay compliant with organic labeling if you sell produce.

The SunGro bag provides a single 2‑cubic‑foot (approximately 16 quarts) package with a premium blend of perlite, pumice, and earthworm castings, while the Black Gold 3‑pack offers three 16‑quart bags for a total of 48 quarts. Per cubic foot, the 3‑pack generally offers a lower price point, but the SunGro bag may include additional fertilizer and a more refined mix. If you need a large quantity, the 3‑pack gives better value; for a single, high‑quality batch, the SunGro bag is a solid choice.

Both perlite and pumice are lightweight, porous minerals that improve aeration and drainage, preventing root rot in container plants. Their structure also helps retain moisture while allowing excess water to flow away, which is especially useful in indoor environments where over‑watering is common. Including these amendments ensures healthier root development and better overall plant vigor.

Black Gold’s All‑Organic blends are formulated for versatile use, making them suitable for indoor containers, raised beds, and outdoor garden beds. However, outdoor applications may benefit from additional mulching or top‑dressing to protect against erosion and extreme weather. For highly acidic or alkaline native soils, you might need to adjust pH with amendments before mixing in the potting soil.

Dan’s Gold Organic Dairy Compost is a mature, aged compost that focuses on improving overall soil structure, organic matter content, and water retention, whereas Black Gold mixes are pre‑blended potting soils with added perlite, pumice, and fertilizers for immediate planting. The dairy compost is ideal for amending existing garden beds or improving heavy clay soils, while Black Gold provides a ready‑to‑use medium for containers. Choosing one depends on whether you need a soil amendment or a complete planting mix.

Check for a sealed, airtight bag with a clear expiration or “best by” date, indicating the product has not been exposed to moisture. Look for certifications such as OMRI, CCOF, or US Compost Council, which signal adherence to organic and quality standards. Additionally, a detailed ingredient list that includes earthworm castings, peat moss, perlite, and pumice shows a balanced formulation for optimal plant health.
