Take a few minutes to inspect your plants.
Remove leaves that are:
- Completely brown
- Severely scorched
- Yellowing and dead
- Damaged by pests
- Diseased
Use clean, sharp scissors or pruners and remove damaged foliage carefully.
Don’t remove healthy leaves simply because their color has changed slightly with the season. Coral bells naturally produce a wide variety of colors depending on the cultivar and growing conditions.
7. Watch for Pests
June is a good time to inspect the underside of leaves and the crown of the plant.
Look for signs such as:
- Holes in leaves
- Chewed edges
- Distorted new growth
- Unusual spotting
- Insects hiding beneath foliage
One pest worth watching for is the black vine weevil. Adult weevils can chew characteristic notches along leaf edges, while their larvae can damage roots.
Regular inspection makes it easier to catch problems before they become severe.
8. Don’t Overfertilize During Extreme Heat
It can be tempting to give plants extra fertilizer when they don’t look their best.
But if your coral bells are stressed by extreme heat or drought, heavy fertilization isn’t necessarily the solution.
Too much fertilizer can encourage tender growth and may contribute to stress, particularly when the soil is dry.
If your plants need feeding, use a balanced fertilizer according to the product’s instructions rather than applying excessive amounts.
9. Check the Crown and Drainage
Coral bells perform best in soil that drains well.
After heavy summer rain, check whether water remains pooled around your plants.
If the soil stays saturated for long periods, investigate the drainage.
Also look at the crown. If the plant appears to be sitting unusually deep in the soil, this can create problems over time.
The crown should remain close to the soil surface rather than being buried deeply.
10. Divide Overcrowded Plants When Appropriate
If your coral bells have become extremely crowded, division can eventually help rejuvenate the planting.
However, the hottest part of summer isn’t usually the ideal time for major division.
If June is already extremely hot in your area, focus on watering, shade, mulch, and general plant care instead.
Save major division or transplanting for a more suitable period when temperatures are moderate and the plant can recover more easily.
What If Your Coral Bells Start Turning Brown?
Don’t panic immediately.
Brown leaf edges can result from several things, including heat stress, drought, excessive sun, or environmental changes.
First check:
Is the soil dry?
Is the plant receiving intense afternoon sunlight?
Is water pooling around the crown?
Are insects damaging the leaves?
Finding the underlying problem is much more useful than simply adding fertilizer or water.
The Secret to Beautiful Summer Coral Bells
The key to keeping coral bells attractive through summer isn’t constant attention.
It’s about getting the basics right:
Consistent moisture + good drainage + appropriate light + mulch + regular inspection.
And remember that different Heuchera varieties can behave differently. A cultivar that thrives in full sun in one garden may struggle in another location with hotter temperatures.
If your coral bells receive harsh summer heat, giving them some protection from the strongest afternoon sun may make a dramatic difference.
Your June Coral Bells Checklist
Before the summer heat really arrives, make sure you’ve:
☐ Checked soil moisture
☐ Watered deeply when needed
☐ Provided afternoon shade if necessary
☐ Added a suitable layer of mulch
☐ Kept mulch away from the crown
☐ Removed dead or badly damaged foliage
☐ Inspected for pests
☐ Avoided excessive fertilizer
☐ Checked drainage
☐ Planned major division for a cooler season
With these simple June tasks, your coral bells can remain healthy and colorful while the rest of the garden battles the summer heat.
Give them the right balance of water, light, drainage, and protection, and those beautiful leaves can continue providing striking color throughout the season.
