    Frequently Asked Questions

    Planting Karl Rosenfield Peony bulbs requires careful preparation and timing to ensure optimal growth.

    • Choose a well-draining location with full sun to partial shade, as these peonies prefer 6-8 hours of sunlight daily. • In early fall, prepare the soil by working in compost or well-rotted manure to improve drainage and nutrient content.
    • Create a hole approximately 12-18 inches deep and wide, and place the bulb with its eyes facing up.
    • Cover with 1-2 inches of soil, leaving the eyes slightly exposed.
    • Space bulbs about 3-4 feet apart to allow for proper growth.
    • Water the newly planted bulbs thoroughly and apply a layer of mulch for insulation.
    • Keep the soil consistently moist but not waterlogged.
    • Monitor for pests, and remove any dead or diseased foliage.

    If you cannot plant your Karl Rosenfield Peony bulbs immediately upon receiving, proper storage is crucial to maintain their health. Store the bulbs in a cool, dry, and dark place with good air circulation, such as a garage or basement.

    Ideal storage temperatures range between 35-50°F (2-10°C). You can place the bulbs in a paper bag, a mesh bag, or wrap them in newspaper, allowing them to breathe while preventing mold growth. Check the bulbs periodically for any signs of rot or mold and discard any affected ones. Plant the bulbs as soon as possible for the best results.

    Karl Rosenfield Peony bulbs typically take two years to produce their stunning, double blooms. Patience is key, as the plant establishes a strong root system and foliage during its initial years.

    To encourage blooming, ensure the bulbs are planted correctly, with the eyes slightly exposed and not buried too deep. Provide adequate sunlight, consistent moisture, and proper fertilization. Once established, Karl Rosenfield Peonies can continue to bloom for decades, offering a spectacular display of color and fragrance in your garden.

    Karl Rosenfield Peonies are considered to be deer-resistant, although no plant is completely deer-proof. Their strong fragrance and unpalatable taste make them less appealing to deer, making them a popular choice for gardeners in areas with high deer populations.

    However, in cases of extreme hunger or limited food sources, deer may still browse on peony foliage. To further deter deer, consider planting deer-resistant companion plants or using deterrents such as fencing, repellents, or motion-activated sprinklers.

    The ideal time to transplant Karl Rosenfield Peony bulbs is in the fall, specifically September and October in most regions. During this time, the plant is dormant, which reduces the risk of transplant shock.

    Carefully dig around the plant, taking care not to damage the roots. Gently lift the plant and move it to its new location, ensuring the new spot has well-draining soil, adequate sunlight, and enough space for growth. Replant the bulb at the same depth as it was originally, and water thoroughly. Add a layer of mulch to help protect the plant during the winter months.
