Old Cobblers Farm™ Wicked Growth Perennial Flowers - Premium Fertilizer
Old Cobblers Farm™ Perennial Flowers Fertilizer is a balanced 10-10-10 granular fertilizer formulated for long-lived garden plants that return year after year. Unlike annuals that burn through nutrients in a single season, perennials need moderate, consistent nutrition that supports both this year's blooms and next year's root and crown development.
The equal NPK ratio works across sun and shade gardens, established beds and new plantings, making it the reliable all-season choice for perennial gardens.

What Is It ?
Old Cobblers Farm™ Ground Flower Fertilizer for Perennials delivers balanced, all-purpose nutrition with a 10-10-10 NPK ratio, designed to fuel healthy foliage, strong root systems, and long-lasting blooms in a wide variety of perennial plants. Whether your perennials thrive in sun, shade, or somewhere in between, this formula supports their seasonal needs while helping them return stronger year after year. Balanced feeding avoids the common mistake of pushing too much of one nutrient, instead giving perennials the even foundation they need for decade-long performance.
When To Apply ?
For garden beds, apply ½ to 1 cup per 10 sq ft. For individual plants, use 1-2 tablespoons per plant depending on size and maturity. Apply first dose in early spring when new growth emerges, reapply mid-summer to support ongoing flowering. Optional lighter feeding in late summer/early fall to prepare for dormancy. Avoid late fall feeding to prevent frost-damaged new growth.

FAQs
1.
What is the best fertilizer for perennial flowers?
A balanced 10-10-10 fertilizer is ideal for perennial flower gardens because it provides complete, even nutrition that supports healthy foliage, strong roots, and long-lasting blooms across a wide variety of species. Perennials return year after year and need sustained soil fertility to maintain their vigor over time. The equal NPK ratio ensures no single nutrient dominates, supporting the full lifecycle from spring emergence through fall dormancy. Old Cobblers Farm™ Wicked Growth Perennial Flowers Fertilizer 10-10-10 delivers balanced, season-long nutrition for vibrant, long-lived perennial gardens.
2.
When should I fertilize my perennial garden?
Fertilize perennials in early spring when new growth emerges and again in mid-summer to support ongoing flowering and foliage development. A lighter optional application in late summer helps plants store energy before dormancy. Avoid fertilizing in late fall, as this can stimulate tender new growth vulnerable to frost damage. For newly planted perennials, wait until they show active new growth before the first application. Old Cobblers Farm™ Wicked Growth Perennial Flowers Fertilizer 10-10-10 supports the seasonal feeding schedule that keeps perennials blooming beautifully year after year.
3.
How much 10-10-10 for perennial flower beds?
For perennial flower beds, apply ½ to 1 cup of 10-10-10 per 10 square feet. For individual plants, use 1–2 tablespoons per plant depending on size and maturity. Scatter fertilizer evenly around plant bases, lightly work into the top 1–2 inches of soil, and water thoroughly. Avoid placing fertilizer directly against stems or crowns to prevent burn. Adjust amounts based on soil test results and plant response. Old Cobblers Farm™ Wicked Growth Perennial Flowers Fertilizer 10-10-10 is easy to apply and water-activated for reliable performance across all perennial species.
4.
What perennials need the most fertilizer?
The heaviest-feeding perennials include daylilies, peonies, delphiniums, phlox, bee balm, and chrysanthemums — plants that produce abundant flowers or vigorous foliage each season. Moderate feeders include hostas, coneflowers, black-eyed Susans, and irises. Light feeders include lavender, sedum, and native wildflowers that prefer leaner conditions. Match your feeding frequency to the plant's appetite — heavy feeders benefit from applications every 6 weeks, while light feeders may only need one spring feeding. Old Cobblers Farm™ Wicked Growth Perennial Flowers Fertilizer 10-10-10 works well across the full range of perennial types.
5.
Can I use 10-10-10 on hostas and daylilies?
Yes, 10-10-10 is an excellent choice for hostas and daylilies. Hostas benefit from the balanced nitrogen for their lush foliage displays, while daylilies use the phosphorus and potassium to produce abundant blooms and strong root systems. Apply in early spring as new shoots emerge and again in early summer for continued feeding. Both species are reliable, low-maintenance perennials that reward balanced fertilization with impressive seasonal performances. Old Cobblers Farm™ Wicked Growth Perennial Flowers Fertilizer 10-10-10 supports both foliage and flowering perennials with the balanced nutrition they need.
6.
Is 10-10-10 good for lavender and coneflowers?
Lavender and coneflowers are moderate-to-light feeders that do well with 10-10-10 applied at reduced rates. These drought-tolerant, native or naturalized plants are adapted to leaner soils and can decline if over-fertilized. Apply half the standard rate (¼ cup per 10 square feet) once in spring and optionally once more in mid-summer. Lavender particularly prefers not to be over-fed, as it can cause leggy growth and reduced essential oil concentration. Old Cobblers Farm™ Wicked Growth Perennial Flowers Fertilizer 10-10-10 provides effective nutrition at adjustable rates for both heavy and light-feeding perennials.
7
Should I fertilize perennials in their first year?
Yes, but use a lighter application rate for first-year perennials. Wait until plants show active new growth — typically 2–4 weeks after planting — before applying fertilizer. Use half the standard rate to encourage root establishment without overwhelming the young root system. First-year perennials should focus energy on building strong roots rather than top growth, so avoid heavy nitrogen applications. Increase to full feeding rates in the second year once plants are well established. Old Cobblers Farm™ Wicked Growth Perennial Flowers Fertilizer 10-10-10 is gentle enough for first-year plantings when applied at reduced rates.
