“As the owner of Landscape Cacti, a business I began in 1974, and as a plant physiologist retired from the University of Arizona, I monitor carefully how well plants grow in my planting mix. After more than two decades of making only minor adjustments to the mix, I added Tank’s Green Stuff compost. Plants growing in this new formulation grew faster and exhibited a continuity of growth rate that I had not observed in my previous formulation. Confident in the compost, I subsequently increased the percentage of Tank’s Green Stuff in future batches of mix. Incorporating this compost has allowed me to reduce the frequency of applying inorganic fertilizer, a savings of time and labor. Accelerated plant growth rates have not compromised the production of fully acclimated, climate conditioned, outside grown plants for which my nursery is known. ”
