The best place to plant coral bells is a spot that gets morning sun, afternoon shade, and soil that drains fast. These three factors matter more than anything else for keeping your heuchera alive and colorful through the seasons. Skip any one of them and you'll watch your plants struggle or die within a year.
Figuring out where to plant heuchera took me longer than I'd like to admit. I lost my first batch of coral bells to crown rot because I put them in a low spot where water pooled after rain. The plants looked fine for about two months. Then the crowns turned mushy and brown at the base. I dug them up and found the roots had rotted away to nothing. My second round went into raised beds with added gravel, and those plants are still thriving four years later.
Coral bells have roots that sit close to the soil surface instead of reaching deep into the ground. This means you need to plant the crown right at soil level. If you bury it too deep, moisture collects around the base and rot sets in fast. If you plant it too high, the roots dry out and the crown gets pushed out of the ground during winter freeze-thaw cycles. UVM Extension warns that these exposed roots are one of the top reasons coral bells die over winter.
Your soil pH matters too. NC State Extension says coral bells prefer slightly acidic soil with a pH between 6.0 and 7.0. You can grab a simple test kit from any garden center for a few dollars. If your soil runs too alkaline, work in some peat moss or sulfur to bring the pH down. Most garden soils fall in the right range without any changes, but it's worth checking before you plant.
Before you commit to a coral bells planting location, run a quick drainage test. Dig a hole about 12 inches deep and 12 inches wide. Fill it with water and time how long it takes to drain. If the water disappears within 30 minutes, your soil drains well enough. If it takes longer than an hour, you need to fix the drainage first. Add 3 to 4 inches of compost and mix it into the top 8 inches of soil. For heavy clay, throw in some perlite or coarse sand too.
I run this test every time I pick a new planting spot, and it has saved me from losing plants more than once. You can also raise the bed by 4 to 6 inches above the surrounding ground to help water flow away from your coral bells. A little prep work before planting gives you years of healthy, colorful plants that won't rot out on you after the first heavy rain.
