Comparison: Best Coast Of Maine Organic Compost (Updated | Nov 11th)

Quoddy Blend focuses on a dark‑brown texture with added lobster and crab meal for extra chitin and calcium, making it ideal for boosting nutrient density. Cobscook Blend is a more versatile in‑ground soil that emphasizes peat moss, compost, and aged bark to improve drainage and aeration across a range of soil types. While both are organic, Quoddy is best for enriching existing beds, whereas Cobscook works well as a base amendment for new garden beds or lawns.

pH determines nutrient availability; acid‑loving plants like azaleas, blueberries, and rhododendrons need a lower pH, which the Acid‑Loving Planting Soil provides. For vegetables, tomatoes, and most garden plants, a neutral to slightly acidic mix such as the Quoddy or Bar Harbor blends works best. Selecting a blend that matches your plant’s preferred pH helps prevent nutrient lockout and promotes healthier growth.

Lobster and crab meal adds chitin, which encourages beneficial soil microbes and improves disease resistance, while also supplying calcium for stronger cell walls. Gardeners who grow heavy‑feeding vegetables or fruiting plants often see better yields with this added amendment. If you’re on a tight budget and grow low‑maintenance foliage, a standard compost blend without the seafood component may be sufficient.

Purchasing the two‑pack gives you flexibility to spread the compost across multiple beds or to store one container for future use, which can be handy for seasonal planting. A larger single bag may reduce per‑cubic‑foot cost but requires more storage space and immediate use to avoid settling. Consider your garden size, storage capacity, and how quickly you plan to apply the product.

OMRI (Organic Materials Review Institute) certification confirms that the product meets strict organic standards, making it safe for certified organic gardening. This assurance is important for growers who sell organic produce or for consumers who want to avoid synthetic chemicals. All the listed Coast of Maine soils and the Stonington fertilizer carry this certification.

Yes, Bar Harbor Blend is formulated with a balanced mix of peat moss, perlite, and organic nutrients, providing good moisture retention and aeration for containers, raised beds, and indoor pots. Its slow‑release nitrogen and micronutrients reduce the need for frequent fertilizing, which is convenient for indoor growers. Just ensure proper drainage to prevent waterlogging, especially in indoor settings.

Apply the granular fertilizer at the recommended rate and water it in so nutrients release gradually with each watering, extending its effectiveness. Because it contains low‑odor lobster, crab, and kelp meals, it’s suitable for indoor plants and grow tents without creating unpleasant smells. Using it in conjunction with a quality organic soil like Quoddy or Bar Harbor maximizes nutrient uptake and overall plant vigor.
