The Water-In™ by Gardinnovations . The Water-In™ represents the first product of its kind, and allows for the roots of plants and trees to be watered directly, thereby conserving a significant amount of water and time. Additional benefits of direct and precise root watering include enhanced soil aeration, reduced weed growth, reduced risk of plant diseases, and deeper root formation. Furthermore, nutrients (fertilizer) could also be delivered directly to the plant without the concern of runoff or overuse.
