Coral Bells Care

Coral bells make wonderful edging plants and put on a show when planted in groups. Their foliage is vibrant and saturated and ​is great for playing up the colors of nearby flowers in the garden—darker purple leaves can make yellow flowers glow, while butterscotch-colored leaves can bring out the tones of simple green leaves.

Caring for coral bells plants is pretty straight forward, and you likely won't need to amend anything or prep in any serious way for their arrival in your garden. They like moderate moisture and will do well in partial shade, which is good news if you have a landscape filled with large shade trees.


Coral bells do best in partial shade, especially in hotter climates. Their color can become washed out if they're kept in full sun, and too much light can cause their leaves to scorch. Keep in mind, coral bells planted in damp shade can be prone to fungal diseases—if your plants start having problems, it's best to move them to a drier site.

Coral bells prefer a humus-rich soil with a neutral to slightly acidic soil pH, somewhere between 6.0 and 7.0. Good drainage is a must, especially in shaded areas, as sitting in the damp soil will cause the crown of the plant to rot.


This plant has medium water needs and likes consistently moist soil. Established plants will tolerate some drought, but an inch of water per week is the best way to keep them happy. If you grow your coral bells in full sun, plan to give them extra water—their shallow roots will need extra moisture during hot, sunny days.

Temperature and Humidity

Most coral bells are hardy in USDA hardiness zones four through eight, although exact hardiness does depend on the variety you're growing. In cold areas, coral bells crowns can heave above the soil line in the winter. Winter mulching will help prevent the freezing/thawing cycle that pushes the plants up, and you should check periodically to make sure the roots are not exposed.


Feed coral bells in the spring with a half-inch layer of compost or a light amount of slow-release fertilizer. This plant has light feeding needs you should avoid heavy applications of quick-release fertilizers, as this will inhibit flowering. Container-grown coral bells benefit from feeding with a water-soluble fertilizer to replenish nutrients that leech from the soil.

How to Care for Alyssum

Remove dead flowers as soon as possible to encourage the growth of additional flowers instead of seeds. Straw and grass clippings make ideal mulch for alyssum.

Alyssum is a genus of flowering plants that can be annuals, perennials or shrubs. They are native to Europe, Africa and Asia but are commonly grown in North America as an ornamental flower. Alyssum plants produce long, oval leaves and flowers that can be pink, purple, yellow or white in color. Most alyssum flowers grown in the United States are annuals, as they usually cannot survive the cold winters.

Plant alyssum during early spring in a location that receives full morning sun and afternoon shade. Use a soil made up of two parts gardening soil to one part peat moss for extra drainage and fertility.

Water alyssum three to four times a week for the first two to three weeks of growth. Reduce watering to one deep soak per week during dry periods after the first few weeks. Do not water alyssum on weeks that receive at least one inch of rainfall.

  • Plant alyssum during early spring in a location that receives full morning sun and afternoon shade.

Sprinkle water over alyssum plants during extremely hot and dry summer days to prevent wilting. Use enough water to moisten the soil and dampen the foliage, without the soil becoming soggy. This will keep the plant from drawing back and ceasing growth during the summer.

Feed alyssum using a balanced 10-10-10 NPK fertilizer once every two months. Do not fertilize during winter, as the plant will not use the nutrients. Water thoroughly after applying to incorporate the fertilizer into the soil. Follow the instructions on the packaging for proper dosage.

  • Sprinkle water over alyssum plants during extremely hot and dry summer days to prevent wilting.

Spread a two-inch layer of mulch around alyssum plants, starting at three inches away from the stems. This will allow room for growth, conserve moisture and reduce the threat of weeds. Refresh the layer of mulch once every two months, or when it becomes visibly eroded.

2. Decide on dimensions that suit your needs.

The height of a raised garden bed is beneficial for two reasons. First, it raises the level of the soil to a height where it’s easier to tend the plants without potentially painful stooping. Second, a raised bed, which is essentially an extra-large planter, is filled with lightweight “fluffy” soil that’s superior to typical garden soil, so plants grow faster and are healthier.

While there are no hard and fast rules for how high a raised garden bed should be, most are between 12 and 20 inches off the ground. Gardeners with mobility issues, such as those in wheelchairs, can opt for even higher sides to make it even easier to reach the plants. To comfortably tend to all areas of the raised bed, it should be no more than three feet wide. That way, you’ll only have to reach 1.5 feet—about an average arm’s length—from either side to reach the plants in the center.

The length of the bed is up to you, but many gardeners find four-foot to five-foot lengths to be most manageable. If you grow a lot of produce, you can install multiple raised beds, but space them at least 24 inches apart to allow adequate walking room between.
