Coral bells, known for their delicate, bell-shaped flowers and leaves that paint the garden in a myriad of colors. In this post, we’ll explore how to care for coral bells. From the light requirements to soil prep, water, fertilizer and finally how to overwinter your coral bells.
Coral bells, also known by their scientific moniker, Heuchera, are an enchanting genus of flowering plants native to parts of America. They are stars of the shade garden, with some 50 species and dozens of hybrids, offering a kaleidoscope of colors in foliage and flowers.
Light Requirements
Coral bells thrive in a variety of light conditions, but they do best in partial shade. Direct, harsh sunlight can scorch the leaves, especially those of varieties with darker foliage. However, too much shade can lead to leggy plants and reduced flowering. Ideal light conditions combine morning sunlight with afternoon shade, offering the perfect balance to maintain vibrant foliage colors and support healthy growth.
Soil Preparation
Proper soil preparation is crucial for the thriving of coral bells. These plants prefer well-draining, moist soil rich in organic matter. Before planting, work compost or aged manure into the soil to improve fertility and drainage. If dealing with clay soil, incorporate sand or peat moss to enhance porosity and prevent waterlogging, which coral bells are particularly sensitive to. The ideal soil pH for coral bells ranges from 6.0 to 7.0, so testing your soil and adjusting its pH with lime or sulfur as necessary can lead to healthier plants and more vibrant foliage.
Planting Your Coral Bells
When it comes to planting your coral bells, timing, and technique matter. Aim to plant in the spring or fall when the weather is cool, as it allows the plants to establish their root system without the stress of extreme heat or cold. Depending on your climate, coral bells can be planted as potted plants or directly from seeds. If planting from a pot, dig a hole twice the width of the pot and just as deep. Gently remove the plant from its container, being careful not to damage the root ball, and place it in the hole. Fill in around the plant with soil and press down lightly to eliminate air pockets.
Grow Coral Bells From Seed
Growing coral bells from seed can be a rewarding endeavor, although it requires patience. Start by sowing seeds indoors, 6 to 8 weeks before the last expected frost. Spread the tiny seeds on the surface of a well-draining seed starting mix, avoiding covering them with soil since they need light to germinate. Keep the soil moist but not waterlogged and maintain a temperature of around 70°F to encourage germination, which typically occurs within 2 to 4 weeks. Once seedlings have developed a couple of true leaves and the danger of frost has passed, they can be hardened off and transplanted outdoors to their permanent positions, adhering to the same soil preparation and planting guidelines as for potted plants. Remember, coral bells grown from seeds may take a year or more to flower, so patience is key.
Water and Fertilizer Needs
Coral bells require consistent moisture to thrive, but they’re also prone to root rot if overwatered. It’s essential to strike a balance, ensuring the soil stays evenly moist without becoming soggy. During the warmer months, a deep watering once a week is usually sufficient, but frequency should be adjusted based on rainfall and temperature. Mulching around the plants can help retain soil moisture and keep roots cool.
When it comes to fertilization, coral bells aren’t heavy feeders, but they do benefit from a boost to support their vibrant foliage and flowers. Apply a slow-release, balanced fertilizer in the spring as new growth appears. Alternatively, use a liquid fertilizer diluted to half-strength every 4-6 weeks during the growing season. Avoid over-fertilizing, as this can lead to leggy growth and compromise the plant’s overall health.
How and When to Divide
Dividing coral bells is a simple process that encourages healthy growth and can invigorate older plants. It’s best done in early spring or late fall when the plant is not in active growth. Look for a plant that has grown large enough to form multiple crowns. This is a clear sign it’s ready to be divided.
To divide, carefully dig around the plant, ensuring a wide berth to avoid damaging the root system. Gently lift the plant from the soil and look for natural divisions between crowns. Use a sharp, clean knife or spade to separate the crowns, making sure each division has a healthy portion of roots attached.
Replant the divisions immediately, following the same soil preparation and planting guidelines as for newly purchased plants. Water thoroughly after planting to help establish the divisions. Dividing not only propagates new plants but also rejuvenates the parent plant, ensuring continued vigorous growth and blooming.
Overwintering Coral Bells
Overwintering coral bells properly is essential for their survival and thriving in the spring. These plants are generally hardy, but they dislike wet feet during the cold months, which can lead to root rot. Start by applying a thick layer of mulch around the base of the plants after the first hard freeze; this helps regulate soil temperature and retains moisture without waterlogging the roots. However, avoid piling the mulch directly against the plants’ crowns to prevent rot.
In regions where temperatures dip below freezing, consider using a frost cloth or burlap to provide extra warmth, especially for less hardy hybrids or during unusually cold snaps. Importantly, monitor the soil moisture levels throughout the winter. While overwatering is a concern, coral bells can still suffer from drought stress if the ground is too dry.
When spring approaches and the threat of frost has passed, gradually remove the protective mulch and any coverings, allowing the plants to acclimate to the warming temperatures. Check for any signs of damage or disease and address these promptly. Proper overwintering ensures that your coral bells emerge healthy and vibrant for another season of spectacular foliage and blooms.
Happy Gardening!
Cultivating coral bells in your garden infuses it with a tapestry of vibrant hues and textures, contributing to its overall beauty and biodiversity. These perennial favorites, with their ease of care, versatility, and visual appeal, prove to be a rewarding addition for both novice and experienced gardeners. By adhering to the outlined soil preparation, planting techniques, and maintenance guidelines, you can foster a thriving environment where coral bells flourish, enhancing your garden’s aesthetic and attracting beneficial pollinators. Remember, gardening is not just about the end result but the joy found in the process.
