Potato Power Fertilizer

Built for Bigger, Better Potatoes

Potatoes need a different kind of fertilizer than most garden crops. Our Potato Power Blend is designed with the nutrients potatoes use most—especially potassium for larger tubers, along with calcium, sulfur, beneficial microbes, and trace minerals. This balanced formula supports strong plants while directing energy into the harvest underground, helping gardeners grow healthier plants and more abundant, better-quality potatoes.

Potato Power Fertilizer Blend

A planting fertilizer designed specifically for growing exceptional potatoes.

Potatoes are heavy feeders, but they don’t want just any fertilizer. What they really need is the right balance of nutrients that supports strong early growth while directing energy into the tubers underground. Our Potato Power Fertilizer Blend is designed with that goal in mind.

This blend emphasizes the nutrients potatoes use most—especially potassium, which drives tuber development, size, and storage quality. It also includes calcium and sulfur to support healthy tuber formation and help reduce common issues like poor texture or scab, along with beneficial biology and trace minerals to keep plants vigorous throughout the season.

What’s in the Blend

Each ingredient is chosen to support potatoes specifically:

Harmony 5-4-3 Organic Fertilizer
Provides balanced, slow-release nutrition to establish healthy plants without pushing excessive leafy growth.

Sulfate of Potash (Potassium Sulfate)
A high-potassium source that fuels tuber formation and bulking. Potatoes are potassium-hungry crops, and this ingredient is key to producing larger, better-quality harvests.

Worm Castings
Adds gentle nutrition, beneficial microbes, and organic matter that help stimulate root growth and soil life.

Gypsum (Calcium Sulfate)
Supplies calcium and sulfur to support strong tuber development and improve overall soil structure.

North Atlantic Kelp Meal
A natural source of trace minerals and plant growth compounds that help plants handle stress and grow more vigorously.

Why It Works for Potatoes

Potatoes respond best to fertilizers that are moderate in nitrogen and high in potassium. Too much nitrogen leads to lush vines but fewer potatoes. This blend focuses on the nutrients that support tuber formation, root health, and overall plant vigor, helping direct the plant’s energy where it matters most—into the harvest.

How to Use

At planting, sprinkle about one tablespoon in the hole for each seed potato piece, then plant as usual.
When plants reach 6–10 inches tall and you hill the soil around them, apply another tablespoon alongside each plant and cover with soil.

Coverage

A 2-lb bag fertilizes approximately 4–6 pounds of seed potatoes, making it the perfect companion to your planting.
