Don’t Treat Your Soil Like Dirt! Bring home a bale of our Happy Frog soil conditioner and your plants will thank you. In every bag of Happy Frog soil conditioner you’ll find finely-screened aged forest products, earthworm castings and bat guano, not to mention soil microbes to help increase root efficiency and encourage nutrient uptake. We also add humic acids, which may increase the uptake of important micronutrients. For additional nutrition, use Happy Frog jump start fertilizer for all new plantings or the Happy Frog fertilizer that’s right for your garden.
