What the mix does
Coast of Maine Sprout Island Seed Starter is an organic starter mix for seeds and cuttings. The blend brings compost, sphagnum moss, aged bark, perlite, kelp meal, shell meal, worm castings, and mycorrhizae into a tray-friendly medium.
That ingredient list gives the bag a rich garden feel before seeds ever reach the shelf.
How it feels in tray work
The mix has a fluffy, earthy feel that suits seed trays, small pots, and cutting containers. Moisten the mix first, fill the cells, level the surface, and plant at the depth listed on the seed packet.
For tiny seeds, scan the surface for coarse pieces and move them to the side of the tray. That small step keeps the planting line easy to read.
Where it fits in the refill shelf
Sprout Island belongs with the spring supplies that repeat through the season: labels, trays, humidity covers, a mister, and a small cleanup towel. It is a useful bag to keep near the bench when new sowing rounds start.
