I’ve tried coconut coir a few years in a row and have suffered from lack of germination and blocks falling apart, so I have gone back to seedling mixes with peat. Next, you’ll need the soil.

Unless you’re a bona fide green thumb, you’ve likely never heard of coco coir before. Pronounced “coco coy-er,” it’s the fibrous husk that comprises the outer layer of a ripe coconut.
