Wicked Growth Roses Fertilizer

Bigger, Longer-Lasting Blooms — A 10-20-15 Formula Built for Roses

Old Cobblers Farm Wicked Growth 10-20-15 is a rose fertilizer blended around what roses actually need through their growing cycle. The 10-20-15 analysis means it contains 10% nitrogen for steady green growth and lush foliage, 20% phosphorus — double the nitrogen — to power big, bold blooms and deep root establishment, and 15% potassium for sturdy stems, petal strength, and longer-lasting blossoms.

Roses are heavy feeders that flower in repeated flushes, so they respond to elevated phosphorus and potassium better than to a balanced all-purpose feed. At 45% total analysis, a 5 lb bag carries 2.25 lb of plant nutrients, and the per-plant rates make it easy to give each bush exactly what its size calls for — from a young miniature to a mature climber.

Key Benefits

Built for bloom power — 20% phosphorus — double the nitrogen — powers abundant flower production and deep root establishment through repeated bloom flushes.

Stronger stems, longer-lasting flowers — 15% potassium supports sturdy stems, petal strength, and blossoms that hold up longer on the bush and in the vase.

Foliage in balance — 10% nitrogen keeps growth steady and green without pushing soft, leafy growth at the expense of flowers.

Works for every rose type — Per-plant rates scale from ½ cup for young miniatures to 2 cups for mature climbers — one bag feeds the whole rose garden.

Concentrated and efficient — At 45% total analysis, a 5 lb bag carries 2.25 lb of nutrients and feeds up to 22 bushes per application.

New plantings included — A planting-hole rate (½–1 cup) gives first-year roses root-building phosphorus right where they need it.

Where to use it: garden beds, borders, containers, and trellis plantings of hybrid tea roses, floribundas, grandifloras, climbing roses, shrub roses, miniature roses, landscape and groundcover roses, and English and heirloom varieties — first-year plantings and established bushes alike.
