Wicked Organics 0-12-0 Rock Phosphate Fertilizer

Natural, Slow-Release Phosphorus for Roots, Blooms and New Plantings

Old Cobblers Farm™ Wicked Growth Rock Phosphate 0-12-0 is a natural, slow-release phosphorus amendment for lawns and gardens. The 0-12-0 analysis is deliberately single-purpose: 0% nitrogen, 12% phosphate and 0% potassium — all phosphorus. Phosphorus is the nutrient most associated with root development, flowering and fruiting, and with helping new plants and lawns establish a strong foundation.

Because it is rock phosphate — a natural, mined mineral — the phosphorus releases slowly, providing sustained availability over time rather than a quick hit. That makes it well suited to building soil phosphorus and supporting root systems during establishment, rather than to fast green-up. It is a phosphorus-only product, not a complete fertilizer, so pair it with a nitrogen source (and potassium where needed) when your plants need full feeding.

Use it when starting new lawns or gardens, when transplanting, and where a soil test shows your soil is low in phosphorus. Phosphorus does not green a lawn — that job belongs to nitrogen — so think of this as a root-and-foundation product rather than a color product.

Where to use it: new lawn and garden establishment, transplanting and bed preparation, and established plantings where a soil test shows phosphorus is needed.

Key Benefits

•  Phosphorus for Roots: 12% phosphate supports root development and a strong foundation for plants.

•  Supports Flowering & Fruiting: Phosphorus is the nutrient most associated with flower and fruit production.

•  Natural, Slow-Release: Rock phosphate is a mined mineral that releases phosphorus slowly for sustained availability.

•  Ideal at Establishment: Especially useful when starting new lawns and gardens or transplanting.

•  Builds Soil Phosphorus: A long-term amendment for soils that a test shows are low in phosphorus.

•  Single-Purpose Simplicity: One nutrient, clearly labeled — add it alongside your nitrogen feed as needed.

•  Easy to Apply: Spread and work into the soil; water in gently without causing runoff.

Best Uses

•  New lawn establishment (at seeding/sodding, where P is permitted)

•  New garden beds and bed preparation

•  Transplanting trees, shrubs and perennials

•  Flowering and fruiting plants needing phosphorus

•  Soils a test shows are low in phosphorus

•  Building soil phosphorus over the long term

Important Notes / Safety

•  Soil Test First: Phosphorus should be added based on need — a soil test tells you whether your soil is actually low in P.

•  Phosphorus Is Often Restricted: Many states and municipalities restrict phosphorus on established lawns to protect waterways. Use mainly for new establishment or a documented deficiency, and always check your local rules.

•  It Won’t Green Your Lawn: Green-up comes from nitrogen — this 0-12-0 product has none. Pair it with a nitrogen feed for color and growth.

•  Not a Complete Fertilizer: Phosphorus-only — combine with nitrogen (and potassium) sources for full feeding.

•  Apply & Water In Gently: Work into the soil and water in lightly without causing runoff; phosphorus runoff is an environmental concern.

•  Conventional Product / Storage: A Wicked Growth product (not organic). Store cool, dry and sealed, away from children and pets.
