Our Flower Window Box Success Kit provides the optimal combination of planting mix and fast-acting nutrients for your biggest and most colorful window box blooms. It starts with our exclusive Eco-Co Coir Potting Mix. Made from coconut husks, earth-friendly Eco-co Coir has excellent water-holding capacity yet drains well — so important for healthy root growth. Easy Bloom fertilizer is formulated specifically for plants growing in containers, because they need a ready supply of high-quality nutrients at all times. Easy Bloom contains no animal by-products or bone meal; it's odorless and won't attract animals. Simply mix this concentrated dry fertilizer in water, following the dilution rates on the label, and use it to hydrate the coir before planting. Then, continue to fertilize window box flowers with Easy Bloom for season-long success.
