XTreme Gardening

In 2008, the idea for Xtreme Gardening came about, inspired by the Xtreme Gardeners: competitive gardeners growing their largest fruit or vegetable. 2006 was the first year that our product was used in the arena, and the largest pumpkin ever grown was produced: a 1,509lb pumpkin by grower Ron Wallace of Rhode Island. Every year since, records have been shattered by the use of our products, and the grower’s passion of soil biology.

Nutrients / Additives

Plants need nutrients to grow and thrive. To maximize your plant growth and yield you will need to provide more than one fertilizer. Our selection will help your plants optimize their growth and production. Not sure which nutrient or additive to use? Ask us, we love to garden.
