To grow healthy, heavy yields of tomatoes, you have to start by taking care of the soil they grow in. A concentrated liquid containing a proprietary blend of beneficial bacteria and mycorrhizal fungi, truly a one of a kind solution - just mix with water and it is ready to apply. Conditions the soil, helping restore its natural biological activity and helps break down organic matter that causes blight in tomatoes. The mycorrhizal fungi strengthens the tomato plant's root system helping the root mass expand and grow longer and deeper into the soil making the plant more tolerant to drought and wind - as well as helping to expedite growth.
