Understanding the Growth Habit of Erigeron Glaucus
Erigeron glaucus is a perennial plant that forms a low-growing, mounding habit, typically reaching a height of 6-18 inches.

These flowers bloom in shades of blue, purple, or white, adding a splash of color to any garden setting.
Benefits of Pruning Erigeron Glaucus
Regular pruning offers numerous benefits for Erigeron glaucus:
- Promotes bushier growth: Pruning encourages the plant to produce more side shoots, resulting in a denser and more compact form.
- Enhances flowering: Pruning removes spent blooms and stimulates the production of new flower buds, leading to an extended blooming period.
- Improves air circulation: Pruning helps to open up the plant’s interior, allowing for better air circulation and reducing the risk of disease.
- Controls size and shape: Pruning allows you to maintain the desired size and shape of the plant, preventing it from becoming overgrown or leggy.
Tools for Pruning Erigeron Glaucus
To properly prune Erigeron glaucus, you will need the following tools:
- Sharp pruning shears
- Gloves (optional)
When to Prune Erigeron Glaucus
The optimal time for pruning Erigeron glaucus is in the spring, before new growth begins. You can also prune in the fall, after the plant has finished blooming. Avoid pruning during the summer months, as this can stress the plant and reduce flowering.
How to Prune Erigeron Glaucus
Follow these step-by-step instructions to effectively prune your Erigeron glaucus:
1. Remove dead or damaged stems: Begin by removing any dead, diseased, or damaged stems from the plant. Cut these stems back to the base of the plant.
2. Prune spent blooms: Deadhead spent flower heads by cutting them back to the nearest leaf node. This will encourage the plant to produce new blooms.
3. Cut back stems: Cut back the remaining stems by one-third to one-half their length. Make clean, angled cuts just above a leaf node.
4. Shape the plant: If desired, you can shape the plant by pruning it into a specific form, such as a rounded bush or a cascading mound.
5. Remove suckers: Remove any suckers that may form at the base of the plant. These suckers can divert energy away from the main plant, reducing its vigor.
Post-Pruning Care
After pruning your Erigeron glaucus, follow these care tips to ensure its recovery and continued health:
- Water deeply: Water the plant deeply after pruning to help it recover from the stress of pruning.
- Fertilize: Apply a balanced fertilizer to the plant to provide it with the nutrients it needs for growth and flowering.
- Mulch: Spread a layer of mulch around the plant to help retain moisture and suppress weeds.
Additional Tips for Pruning Erigeron Glaucus
- Use sharp shears: Dull shears can crush the stems, making it easier for disease to enter the plant.
- Make clean cuts: Make clean, angled cuts to promote healing and reduce the risk of infection.
- Avoid over-pruning: Pruning too severely can weaken the plant and reduce flowering.
- Prune regularly: Regular pruning will help to maintain the plant’s health and vigor.
Troubleshooting Common Pruning Problems
- Plant is not flowering: If your Erigeron glaucus is not flowering, it may be due to over-pruning or insufficient sunlight.
- Plant is leggy: If the plant is leggy, it may be due to a lack of pruning or insufficient sunlight.
- Plant is diseased: If the plant is diseased, remove the affected stems and treat the plant with an appropriate fungicide.
