Moisturin 5 from GSI Horticultural is a dual-purpose liquid coating that forms a prophylactic-type shield on plants. The barrier is so strong that it locks out insects and disease without killing anything. It also keeps moisture in the plant to stop stress from transplanting, water shortage, extreme weather events, frost, and salt damage. Because Moisturin 5 provides so many varied benefits to your garden it is extremely cost-effective. But the real benefit is not having to buy products that are dangerous and have the word "Kill" on them.
