Used as a seed inoculant, seaweed fertilizer increases and accelerates germination, and enhances the rapid development of a healthy root system. Seaweed is an excellent additional to any fertilizer program. Directions: Shake well before using. Prepare for one application only. Do not store diluted fertilizer.
