A.M. Leonard knows you want to grow the healthiest and most beautiful plants and lawn possible. When plants are at their healthiest, they reach their full size, greatest strength, and biggest yield. Our fertilizers, treatments, and plant food helps lawns and plants grow big, strong, and green as can be. Healthy plants simply look the best. They have the largest, most beautiful flowers and vibrant green leaves. They are the tallest trees that produce the most and best-tasting fruit. With strong roots and stems, healthy plants are also more resistant to anything that might harm them. No matter if you‘re growing a tree, a vegetable, or a flower, we have the plant food you need.

Slow-release fertilizers such as the Osmocote 14-14-14 are very popular products, offering a wide range of uses from greenhouse to planter and cutting down labor with their time-release formulas. We also carry plant and flower fertilizers including brands such as BioPlex and Grotab, lawn and grass fertilizers, and organic options as well. And when your plants and yards begin to thrive, keep it that way with our herbicides, fungicides, and insecticides.

If you're just getting started or preparing for your next task, we carry a range of greenhouse supples including grow lights and seed starting supplies, as well as nursery supplies including a variety of pots and ground cover options.
