Our top-selling Terra-Sorb Hydrogel is a great option for contractors and landscapers attempting to plant in rugged conditions not typically suitable for growth. This commercial-grade co-polymer helps plants survive brutal dry spells and thrive in areas that lack proper irrigation. By absorbing 200 times its weight in water and releasing it slowly over a long period of time, Terra-Sorb Hydrogel will help significantly reduce water usage and save you time and labor.

For your plants that are stressed from transplanting, shipping, or extreme weather, try our Root Zone Plant Conditioner. This unique product helps boost anti-stress hormones for a healthier, more attractive appearance.

There's no shortage of soil amendments available, and at A.M. Leonard you'll find a great selection curated for the needs of professional landscapers and gardeners. From foliar sprays to transplant formulas, our quality products will keep your plants strong and healthy no matter the conditions.
