The Coast of Maine Difference


Here at Coast of Maine, we are proud of the quality and consistency of our compost-based soils. Compost, we believe (naturally decomposed organic matter) is the key ingredient.
Ours are made using carefully designed and tested recipes which include the very best ingredients (sustainably sourced from pristine ocean waters and local farms) combined with rigorous quality controls. We never use biosolids, municipal or household waste. Close attention to detail with frequent turning, sampling and testing plus a lengthy aging and curing process produces dark, rich compost.

We use all natural ingredients

Wiscasset Blend™ Organic & Natural Earthworm Castings are odor-free and can be used both indoor and out. Wiscasset Blend™ contains no chemical fertilizers or synthetic substances, and is safe to use anywhere.
Wiscasset Blend™ is named after the picturesque Mid-Coast village long known as the “prettiest” in Maine. Located on the Sheepscot River just up from Boothbay Harbor, Wiscasset was home to thriving shipping, shipbuilding, and lumber industries, and the busiest seaport north of Boston in the 1880s.

Follow these few simple steps

For use with flowers, vegetables, herbs and houseplants. Thoroughly mix Wiscasset Blend™ Earthworm Castings into the top of garden, potting or container soil, tamp down and water-in thoroughly.

How much Wiscasset Blend will you need?

Pots and containers

  • For a 6″ pot, sprinkle two tablespoons on the top of the soil, scratch in and water.
  • For a 12″ pot, sprinkle four tablespoons on the top of the soil, scratch in and water.
  • For a 24″ pot, sprinkle eight tablespoons on the top of the soil, scratch in and water.

Window boxes and hanging baskets

Apply liberally to cover the soil surface with a 1/4″ layer of earthworm castings. Scratch in and water.

Trees and shrubs

Top-dress a generous layer of earthworm castings around the drip line of the plant, (the lateral diameter of the shrub or tree).

Compost tea

Mix one cup of worm castings in a gallon of water, stirring vigorously to aerate. Let it sit for an hour and then stir again. Use the finished mixture to water-in the soil around vegetables, annuals, perennials, trees and shrubs. Or you can use as a foliar spray by applying the liquid directly to the leaves with a watering can or spray applicator.
