Since ancient times, frogs have been symbols of rebirth and renewal.  Chinese legend tells of Ch’an Chu, the toad who knew the secret to eternal life.  In Native American lore, the frog is the protector of the waterways.  There’s a reason that frogs hold such a powerful place in mythology: if you’ve ever walked along a river or through a damp forest, you know that frogs thrive in healthy habitats.  When the frogs vanish, it is a sign that the forests and streams are in trouble.  That’s why we named our soil conditioner Happy Frog®.  The very life cycle of a frog reminds us of the promise of spring: a slippery brown tadpole transforms itself into a glorious, glistening creature that travels between the twin realms of water and earth, and leaps into the sky out of pure joy.  Embrace the vitality of Happy Frog®!

Don’t Treat Your Soil Like Dirt®

Happy Frog® Soil Conditioner is amended with soil microbes.  These little guys help improve root efficiency and encourage nutrient uptake.  That’s why we never steam sterilize our soils. 

Our craftsmanship shows in the finely-screened forest products, bat guano and earthworm castings you’ll find in our mixes.  Bat guano has been used for centuries as a fertilizer for all kinds of plants.  Add earthworm castings and you have a nutrient-rich mix that can help your plants thrive.

HAPPY FROG® Means NO Guesswork

Happy Frog® Soil Conditioner contains a carefully selected, custom blend of mycorrhizal fungi.  Mycorrhizae occur naturally in forest soils where the humus content is high and the soil is thriving with microbial life.  Once in contact with the plant’s root system, mycorrhizae may colonize directly onto the roots, helping enhance root efficiency in the rhizosphere.  This may enable the plant to take up more nutrients and resist stress, resulting in enhanced fruit and flower production.

Happy Frog® Soil Conditioner also contains Humic Acids, naturally occurring materials that are extracted from Leonardite.  Humic Acids are found in certain soils, coals, and peat resulting from the decomposition of organic matter.  Humic Acids may increase micro-nutrient uptake. 

All FoxFarm products are grow tested in our greenhouse laboratory.
