The growing environment can vary significantly from one area to another. Many gardeners wonder what conditions their plants can tolerate
Quick Answer: Heuchera can grow in clay soil if amended slightly. Mix half a bucket of soil conditioner into the planting hole with the native soil. This will make a good soil mix for this plant.

Amend your soil
Heuchera can tolerate clay soil, but it would still be good if you added a little organic matter to it. Organic matter will make the soil more friable, better drained, and more nutritious, allowing the plant to grow faster and be healthier.
A soil conditioner is the first thing you can use as a soil improver. These are usually made from plants and are very good for improving the quality of the substrate.
Compost also works well. It is a nutrient product created by the decomposition of plant waste. The main thing is that it should be appropriately prepared and free from diseases and pests.
You must apply about half a bucket or more organic matter for each bush. Heuchera will take root in such a soil mix quite quickly and easily penetrate the roots into pure clay soil.
Drainage
The next improvement you have to make is drainage underneath where the heuchera is growing. Clay soil holds a lot of water, but you may also have a high water table. In that case, drainage is a must.
Dig a hole three times the size of the root ball of Coral Bells and pour a bucket of water in. If the water is still in the hole after a few hours, the groundwater is too high.
Wait until the water comes off entirely and fill the hole one-third full with pebbles. River pebbles of medium size work best.
Then, you can plant the heuchera in the hole using draining soil. If you have done everything right, the water will go below the root system, and the plant will be fine.
Also, make sure that no rainwater flows near the heuchera. For example, water from the house’s roof should not run near where the plant is growing. If necessary, transplant the plant further away.
Watering in clay soil
You must be very careful when watering heucheras in clay soil because it can stay wet long after it rains. Even if the top layer dries out, it creates a dense crust under which the soil is wet.
Do a finger test before watering. If the soil is more than 2 inches dry, water. Use about 1 gallon of water for each plant.
Avoid watering in rainy weather because you can overwater the soil, and root rot can occur.
Avoid watering in the winter because this is the time of year when the plant needs minimum water, and the soil is usually wet. The exception to this is a very dry, warm winter.
Fertilizing
Feeding heuchera in clay soil is a must due to its nutrient-poor nature. If you do not fertilize, heuchera can grow very slowly, and the leaves may turn yellow.
Coral Bells need a slow-release granular fertilizer. Choose one with approximately equal amounts of nitrogen, phosphorus, and potassium. Apply the fertilizer in early spring, following the directions on the package.
You can also use liquid fertilizer for perennials in clay soil. Use it no later than mid-summer. Avoid fertilizing in late fall and winter.
