Karl Rosenfield Peony Plant

Karl Rosenfield is considered by many to be one of the best red double blossom peonies. The large, rose-shaped cherry red double blossoms that can get up to 6 inches wide. Makes a great addition to a cut flower garden. Karl Rsenfield ships as a bare root. We like growing from bare roots because they establish quickly, become twice the size of a potted plant in the first season, and eliminate the need for plastic pots (a win for the environment).

Planting Instructions:

• - Best planted in fall for optimal root establishment
• - Space plants 3-4 feet apart to allow for mature growth and airflow

Soil Preparation:

• - Ideal soil pH: 6.0-7.0
• - Prefers well-drained, fertile soil enriched with organic matter

Watering Specifics:

• - Water deeply when first planted, keeping the soil moist but not waterlogged
• - Once established, Peonies are relatively drought-tolerant but appreciate consistent moisture during dry periods

Fertilizer Type:

• - Apply a balanced fertilizer in early spring to promote healthy growth and blooming
• - Avoid over-fertilizing, as this can lead to excessive foliage at the expense of blooms

Pruning and Training:

• - Deadhead spent blooms to maintain appearance, but leave foliage intact to nourish the roots
• - Cut back the foliage to ground level in late fall to prepare for the next growing season

Additional Pest Management:

• - Peonies are generally pest-resistant but can attract ants, which are harmless to the plant
• - Ensure good air circulation to prevent fungal diseases like botrytis

Blooming Indicators:
