Buying Guide
FAQs
Which Coast of Maine blend should I buy for large container plants?
For large containers, the Stonington Blend is formulated with a balanced mix of peat, perlite, and natural nutrients that promote strong root growth. It comes in pack sizes of 2, 4, or 6 cu ft, so you can choose the quantity that matches the volume of your containers. Larger packs offer a lower cost per cubic foot, making them the most economical choice for extensive container gardening.
How does the Penobscot Blend differ from the Bar Harbor Blend?
Penobscot Blend focuses on improving soil texture with peat, lobster shells, and aged bark, making it ideal for amending sandy or compacted garden beds. Bar Harbor Blend, on the other hand, includes perlite and kelp meal for enhanced moisture retention and aeration, suitable for both indoor and outdoor plants. Choose Penobscot for soil revitalization and Bar Harbor for a versatile, all‑purpose potting mix.
Is the Castine Blend better for raised beds than the Stonington Blend?
Castine Blend is specifically marketed for raised beds, offering a nutrient‑rich composition that supports deep root development in confined spaces. While Stonington Blend works well in large containers, it can also be used in raised beds but may not provide the same level of soil structure improvement. For dedicated raised‑bed projects, Castine typically delivers better performance.
What are the advantages of buying a larger pack (e.g., 6 cu ft) versus a smaller pack?
Larger packs reduce the price per cubic foot and minimize packaging waste, delivering better overall value. They also ensure you have a consistent soil mix throughout your garden, avoiding variations that can occur when mixing different batches. If you have multiple beds or containers, buying in bulk is both cost‑effective and convenient.
Can I use the Sprout Island Seed Starter mix for transplanting seedlings into larger pots?
Yes, the Sprout Island Seed Starter provides a light, well‑draining medium ideal for germination and early root growth, and it can be mixed with a regular potting soil when transplanting larger seedlings. Its inclusion of mycorrhizae and worm castings gives seedlings a nutrient boost during the critical transition phase. However, for long‑term growth in larger containers, consider switching to a blend like Bar Harbor or Stonington.
Are all these Coast of Maine products certified organic?
All listed blends are OMRI‑listed and meet organic gardening standards, meaning they contain no synthetic fertilizers or pesticides. The ingredients are sourced from natural, renewable resources such as composted salmon, kelp, and lobster shells. This certification ensures they are safe for organic gardening practices and environmentally friendly.
Which blend offers the best value for indoor houseplants?
The Cape Neddick Blend (16 qt) is tailored for indoor houseplants, providing a lightweight, organic mix that promotes strong root development and lush foliage. Its smaller bag size makes it easy to store and use for typical indoor plant collections. While Bar Harbor also works indoors, Cape Neddick’s formulation is optimized for the unique moisture and aeration needs of houseplants.
How do I decide between the Stonington Blend pack of 2 cu ft and the pack of 4 cu ft?
If you have a modest number of containers or want to test the mix before committing, the 2 cu ft pack offers a lower upfront cost and less storage space. The 4 cu ft pack provides a better price per cubic foot and is ideal if you plan to fill multiple large containers or raise several beds. Consider your current project size and future gardening plans when choosing the pack size.
