Buying Guide
FAQs
What should I look for when choosing a Coast of Maine compost blend?
Focus on the primary ingredients, such as lobster and crab meal for extra chitin, peat moss for moisture retention, and aged bark for structure. Also check if the product is OMRI listed, which guarantees it meets organic standards. Consider the intended use—whether you need a soil amendment for beds, containers, or acid‑loving plants.
How does the Quoddy Blend compare to the Cobscook Blend?
Quoddy Blend emphasizes chitin‑rich lobster and crab meal, which boosts nitrogen and improves root development, while Cobscook Blend is a more balanced mix of peat, compost, and bark for overall soil health. Quoddy is ideal for gardeners wanting a boost in nutrient density, whereas Cobscook excels at improving texture in sandy or clay soils. Both are OMRI listed, but Quoddy may be pricier due to the seafood component.
Is there a benefit to buying the 2‑pack or 10‑pack versions of Quoddy Blend?
Larger packs lower the cost per cubic foot and reduce packaging waste, making them a better value for extensive garden beds or multiple projects. Smaller packs are convenient for trial use or limited‑space container gardening. Choose the size that matches the scale of your planting area and your storage capacity.
Can I use the Wiscasset Blend earthworm castings as a top‑dressing for indoor plants?
Yes, the Wiscasset Blend is odorless, finely textured, and rich in micro‑nutrients, making it perfect for houseplants and seedlings. It improves water retention and makes nutrients more readily available without overwhelming the plant. Just apply a thin layer on the soil surface and water as usual.
What makes the Acid‑Loving Plant Soil different from the vegetable blends?
The acid‑loving mix is formulated with a low pH to suit plants like azaleas, rhododendrons, and blueberries, whereas the vegetable blend has a neutral pH optimized for tomatoes and other edibles. Both provide balanced moisture retention and drainage, but the acid blend includes specific amendments to maintain acidity over time.
How do I know if a compost is worth the price?
Compare the ingredient list, organic certification, and the volume you receive; products with specialty ingredients like lobster meal often carry a premium but deliver higher nitrogen levels. Look for customer reviews that mention plant vigor and soil improvement. A higher price is justified when the blend offers unique nutrients or superior texture for your gardening needs.
Can I mix different Coast of Maine products for a custom soil blend?
Absolutely—mixing a nutrient‑dense blend like Quoddy with a texture‑enhancing blend such as Cobscook can create a well‑rounded soil amendment. Start with a 1:1 ratio and adjust based on plant response; more Quoddy adds nitrogen, while more Cobscook improves drainage. Ensure the final mix remains OMRI listed if you need to maintain organic certification.
