Coast of Maine Quoddy Blend Lobster & Crab Organic Compost is a soil amendment built from chitin-rich lobster shells, composted cow manure, sphagnum peat moss, and composted bark. It is suited to vegetable beds, flower borders, ornamental plantings, and container growing.
OMRI listed for organic use, it has been part of Coast of Maine's product line since the company began focusing on regenerative soil practices in 1996. Because the formula includes seafood-derived ingredients, it may attract animals and wildlife to treated areas.

For Gardeners Looking to Improve Tired or Depleted Soil Before Planting
If you are working with soil that has been through multiple growing seasons or container mix that has lost its structure and fertility, this compost provides organic matter, calcium, and chitin in a single amendment. You can incorporate it into garden beds before planting, blend it into container mixes, or use it to top dress established plantings and work it in at the end of the season.
The sphagnum peat moss and composted bark contribute to improved drainage and aeration, which matters most in heavy clay soils or densely packed container media. It is also a practical choice for indoor container plants where a clean, dry organic amendment is preferred.
What to Expect from the Coast of Maine Quoddy Blend Lobster & Crab Organic Compost in Real Use
Gardeners who use this compost regularly report visible improvements in plant productivity, particularly in vegetable beds. Tomatoes and other fruiting crops have shown stronger growth and better yields when this amendment was incorporated into the soil. Those using it in containers have noted that it keeps plants performing well across multiple growing cycles, including indoor plants.
The compost is described as rich and dark, with some larger chunks present in the mix. The lobster shell content contributes calcium to the soil, which is especially relevant for crops prone to calcium deficiency.
One note worth being aware of: because the formula includes seafood-derived material, dogs and wildlife may show interest in areas where it has been applied, even well after initial use. This is worth considering if you have open garden beds accessible to animals.
The product is well regarded for use in organic growing systems, including container-based and true living organic setups.

Frequently Asked Questions
Can Coast of Maine Quoddy Blend Compost be used for indoor container plants?
Yes. The compost works in indoor containers as well as outdoor beds. Its dry, bark-and-peat base blends into potting mixes without creating excessive moisture issues, and the organic nutrient content supports plant health through multiple growing cycles. It has been used successfully for a range of indoor plants including herbs and vegetables grown under artificial light.
Does the lobster shell content in this compost add calcium to the soil?
Yes. Lobster shells are a natural source of both calcium and chitin. Calcium supports cell wall development in plants, which is particularly relevant for crops like tomatoes and peppers that are susceptible to blossom end rot when calcium is deficient. Chitin has also been associated with supporting soil biology and can influence root zone health over time.
Will the seafood ingredients in this compost attract animals or pests?
The lobster shell and seafood-derived components can attract dogs, wildlife, and potentially other animals to treated areas. This attraction has been reported to persist for a year or more after application in some cases. If your garden is in an area with regular wildlife activity or you have free-roaming dogs, this is worth factoring into how and where you apply it. Raised beds or fenced areas may reduce the risk.
