Here’s what Sarah Sterling, the school’s Associate Director of College Counseling, had to say about the Organic Mechanics products used in their horticulture education:
“The Shipley School’s horticulture program provides all members of the community with opportunities to learn together, grow as individuals, and cultivate well-being through horticultural initiatives. As an educational institution, sustainability and hands-on learning are integrated into our program.”
“Using Organic Mechanics products means that our students can plant flowers and grow food, without the concern of coming into contact with harmful chemical fertilizers. Additionally, since our horticultural activities range from seed-starting to designing and planting exhibits for the Philadelphia Flower Show, Organic Mechanics always has the right soil for the job.”
It’s such a blessing to know our creations have such an impact.
Wholesale-Specific Products
100% Biochar
We recommend mixing your desired nutrients, biology, and minerals with Biochar for a minimum of four weeks before using it. This allows time for the Biochar to become inoculated.*
Biochar improves soil quality for a lifetime, so soil performance gets better year after year!
For Containers, mix in at a 5% rate with your preferred growing medium, such as Container Blend or Cocodelphia
For Garden Beds, 1 cu. ft. will cover 48 sq. ft. at a 5″ depth
100% Organic!
*Skipping the inoculation step reduces effectiveness the 1st year, as Biochar will adsorb nutrients and minerals from the surrounding soil, reducing plant-available nutrients in the soil solution. Work with a pre-inoculated Biochar Blend for best results. However, in some landscape situations, blending pure Biochar into soil has advantages that outweigh this limitation.
