Mykos - Pure, Fresh & Alive: Being beneficial organisms, mycorrhizae live on the roots of plants and form a symbiotic relationship. They then extend microscopic straw-like filaments called "hyphae" into the soil with which they extract, transport, and dramatically increase a host plant's supply of nutrients and moisture. Pockets of nutrients and water in the soil which were once unreachable by standard root systems are now made accessible through the "super-mining" effects which mycorrhizae gift to your plants. Mycorrhizae also release a glue-like substance into the soil (Glomalin) which improves water storage and capacity, leading to lower watering costs. Although ideal for use on all plants, mycorrhizae are especially beneficial toward: tomatoes, herbs (thyme, basil, sage, etc.), pumpkins, beans, bulbs (all), squash, cantaloupe, carrot, celery, corn, cucumber, garlic, leek, lettuce, melon, onion, peas, potato, strawberry, and grape varietals. Mycorrhizal fungi are ancient in origin and the benefits are boundless. Pound for pound, mycorrhizae provide plants with the greatest possible benefit for the smallest amount of input. With a single inoculation, mycorrhizae are capable of transforming the ordinary garden into something Xtreme! Granular 100g. 2-year guaranteed shelf life.
