Age Old Liquid Kelp (.3-.35-.15) is the original soil conditioner and plant stimulant derived from 100% Northern Sea Kelp (Ascophyllum Nodosum). As a soil drench it helps build tilth and restore biological life to damaged soils. Naturally mild, it is most commonly foliar sprayed to improve nutrient uptake and reduce environmental stresses without adding excess nutrients to the growing medium. Foliar spray during major temperature and humidity swings increases strength and stability for plants. Age Old Liquid Kelp can also help get a plant back in balance after excessive water, fertilizer or chemical applications.
