Seaweed

Seaweed gently nourishes seedlings and sprouts up to the second, "true" leaf stage, all along promoting vigorous root growth. Typically, seaweed is diluted into a foliar spray and applied according to the directions on the product label. Seaweed formulated with iron is especially helpful for plants that need acid soils. All plants can benefit from a foliar application of seaweed spray at any stage.
