How to Use and Care for Apple Twist Coral Bells in 20-Cell Plug Trays
Save
Apple Twist is a coral bells grown for foliage that changes through the season. Here is how to get the most from Apple Twist Coral Bells 20-cell plug trays: what to do the day they arrive, how to plant them and how to care for them through the first season and beyond.
What comes in a 20-cell tray
One 20-cell tray holds 20 large, field-ready plugs of Apple Twist Coral Bells in cells about 2 3/4 inches wide and 3 1/4 inches deep. Each plug has a bigger root system than a small cell, so it can go straight into the garden or into a 1-gallon pot. Planted about 22 inches apart, one tray fills about 70 square feet.
The first 24 hours
Open the box right away and set the tray in bright shade out of the wind. Lift a few cells: if the tray feels light or the soil looks pale, water from below by setting it in an inch of water for 10 minutes, then let it drain. Give the plugs a day or two to recover before transplanting. Plants that have been in a box need 7 to 10 days of hardening off: set them outside in light shade for a few hours, leave them out a little longer each day, and bring them in if frost is forecast.
How to plant Apple Twist Coral Bells 20-cell plug trays
Choose a spot with part sun to full shade and rich soil that stays evenly moist. Water the tray an hour before planting. Push each plug up from the bottom of the cell or squeeze the cell; never pull plugs out by the stems. Plant at the same depth it grew in the cell, firm the soil around it and water in well. Space plants about 22 inches apart, their mature width. These larger plugs can go straight into the garden. If your beds are not ready, pot them into 1-gallon containers and plant them out within the season.
Watering through the first season
Plug cells dry out fast. Check new plantings every day for the first 2 weeks and water whenever the top inch of soil is dry. After that, water deeply once or twice a week through the first summer unless it rains. A thin layer of mulch, kept away from the stems, holds moisture and keeps weeds down.
Season-by-season care
Grow in part to full shade in humus-rich, well-drained soil kept evenly moist; soggy winter soil causes crown rot. Hardy in zones 4 to 9. Trim off tattered leaves in early spring, and replant or mulch any crowns that heave out of the ground over winter.
Winter care by zone
Apple Twist Coral Bells is hardy in USDA zones 4 to 9, which includes West Michigan (zone 6). Fall-planted plugs should go in the ground at least 6 weeks before the ground freezes so roots can anchor before winter. In the first winter, add a few inches of loose mulch after the ground freezes to keep young roots from heaving. Check your zone with the USDA Zone Finder and your last frost date with the Frost Date Estimator.
Where to grow Apple Twist Coral Bells
Coral bells prefer shade and richer, evenly moist soil, so place this one in a shady bed or container away from the lavender, where its chartreuse leaves can light up a dim corner.
