Hello friends! Today, I will tell you how I grow my Coral Bells under pine trees.
QUICK ANSWER: Coral Bells can grow under pine trees because they have a shallow root system and need moderate water. To successfully grow them under a pine tree, use nutritious soil, mulch them with compost, and fertilize them twice a year.
Planting
Plant Coral Bells at least 3 feet from the pine tree’s trunk. The best time to plant is in spring. Choose a cloudy day.
Dig a hole three times the size of the Coral Bells root system. Use a sharp shovel. Chop off the small pine roots to make room. Do not touch the thick roots of the pine tree.
Place the shrub in the hole so the stem is not in the ground. Backfill the entire space in the hole with a nutritious, well-drained soil mix.

Soil
You must use the soil from the planting hole to get a suitable substrate. Mix it with 1-2 buckets of good quality and nutritious compost. Use only quality compost free of pests and diseases.
You can also buy ready-made soil mix for perennials. Give preference to a proven manufacturer with good reviews.
Watering
As I mentioned before, there is such a thing as dry shade under trees. To fix this drawback you need to water your Coral Bells regularly.
It would be best to water your Coral Bells as soon as the soil is slightly more than an inch dry. Nothing will happen if you don’t water in time; the heuchera will survive for 1-2 days without water.
The amount of water should be enough. It would be best to give at least 1 gallon or more for each bush.
Overwatering and root rot are rare if you are growing heucheras under trees. Big trees usually soak up all the extra moisture.
Fertilizing
Compost and slow-release pellets are the best fertilizers to start with. I already explained how to use compost in the chapter on soil preparation.
When planting heuchera, pour about 1 ounce of pellets under each bush. The pellets usually last all season long, so the plant will take root quickly.
It is best to use a multi-purpose fertilizer with about equal parts of the three basic elements (nitrogen, phosphorus, and potassium).
Once a month after planting, water the heuchera with a water-soluble multi-purpose fertilizer. This will give it even more of a boost to get established in a new place faster.
Mulching
The best mulch is organic matter. You can mulch with compost. In addition to other benefits, compost is also an additional fertilizer. But it is worse at preventing weeds from sprouting.
A second good mulch is pine bark. Choose a fraction of 1 to 2 inches. It will be excellent protection against weeds. Also, the bark has a relatively long-lasting life.
The mulch layer should be 1-2 inches thick. To prevent rotting, do not mulch too close to the stem.
