Feed the Ground, Fill the Hills — A High-P&K 8-16-16 Built for Tubers
Old Cobblers Farm Wicked Growth 8-16-16 is a seed potato fertilizer with a 1-2-2 ratio aimed squarely at what potatoes make underground. The analysis supplies 8% nitrogen — enough to power the leafy canopy that feeds the crop without pushing vines at the tubers' expense — alongside 16% phosphorus for root and tuber development and 16% potassium, the nutrient potatoes consume more of than any other, supporting tuber size, uniformity, and storage quality.
Potatoes are a two-act crop: first the canopy establishes, then everything the leaves produce gets shipped underground to the swelling tubers. The feeding schedule matches — a full application worked into the soil at planting, then a side-dressing along the rows at midseason as tuber formation gets underway (hilling time is a convenient moment for it). At 40% total analysis, this is the most concentrated feed in the Wicked Growth line, so measured rates matter.
Key Benefits
Built for what's underground — 16% phosphorus and 16% potassium — double the nitrogen — feed root and tuber development directly, for larger, more uniform potatoes.
Potassium for the keeper crop — Potatoes take up more potassium than any other nutrient; 16% K supports tuber size, uniformity, and how well the harvest stores.
Vines in proportion — 8% nitrogen powers the canopy that feeds the tubers without pushing vines at their expense.
Timed to tuber formation — Worked in at planting, side-dressed at emergence and midseason — the schedule follows the crop's two acts.
The line's strongest blend — At 40% total analysis, the most concentrated feed in the Wicked Growth line — measured rates go a long way.
Garden or grow bag — Rows, raised beds, grow bags, and containers — 1 tablespoon per gallon of soil covers roughly 160 container plantings per bag.
Where to use it: garden rows, raised beds, grow bags, and containers of potatoes — from seed potatoes at planting through midseason.
Application Instructions
Application Instructions
-Side-dressing: 1–2 lbs per 100 sq ft after plants emerge and again at midseason, applied evenly along the rows
-Containers and grow bags: 1 tablespoon per gallon of soil at planting; reapply every 4–6 weeks during the season
-Maintenance: feed established potato beds annually
Steps:
1. At planting: mix the measured amount into the top 6 inches of soil where the seed potatoes will go.
2. After emergence and at midseason: side-dress along the rows, keeping granules off foliage and away from stems — never in direct contact with the plants.
3. Water thoroughly after every application so nutrients reach the root zone.
When and how often: at planting, then side-dress after emergence and at midseason as tubers form. Containers: every 4–6 weeks.
What NOT to do: do not exceed the rates — at 40% analysis this is the strongest feed in the line; do not let granules contact stems or foliage; and do not skip the watering-in.
Ingredients
Ingredients
Diammonium Phosphate / DAP (36%) — The workhorse of this blend — supplies the 16% phosphorus for root and tuber development plus the majority of the nitrogen.
Potassium Chloride (27%) — Also called muriate of potash; delivers the 16% potassium that supports tuber size, uniformity, and storage quality.
