Wet N Gro helps water to penetrate soil more thoroughly and evenly, while adhering to the soil so it doesn't pool at the bottom of the container or spill into the ground without helping your plants. Just 5ml is enough to treat 7 litres of water - enough to water six hanging baskets. You only need to treat once a month, so you can use it on your whole garden and still have plenty left over for next year.
