Blazing stars, also known as Liatris, are popular perennials admired for their tall, striking flower spikes. They add vertical interest to gardens and attract pollinators like butterflies and bees. Proper training and support are essential to help these plants reach their full height and maintain stability, especially in windy conditions or heavy rain.
Understanding Blazing Stars and Their Growth Habits
Blazing stars typically grow between 2 to 4 feet tall, depending on the variety. They have a clumping growth habit with narrow, grass-like leaves at the base. Their flower spikes emerge from the top of the plant, consisting of numerous small, tubular flowers that bloom from late summer to fall.
Why Support is Necessary for Blazing Stars
Although blazing stars are naturally resilient, their tall flower spikes can become top-heavy and prone to bending or falling over. Wind, heavy rain, and uneven soil can exacerbate this issue. Providing support ensures the plants stay upright, promotes better air circulation, and enhances their visual appeal.
Support Strategies for Vertical Growth
Implementing effective support strategies can significantly improve the health and appearance of blazing stars. Here are some proven methods:
1. Use of Garden Stakes
Insert sturdy stakes made of wood, metal, or plastic alongside the plant. Tie the flower spikes to the stakes using soft garden twine or plant ties. Ensure ties are not too tight to avoid damaging the stems. Place stakes at the time of planting to prevent root disturbance later.
2. Installing Support Cages
Support cages or tomato cages can encircle the blazing star, providing a stable framework. Choose cages that are tall enough to accommodate the mature height of the plant. Secure the cages firmly into the soil to prevent tipping during storms.
3. Creating a Trellis System
A trellis made from wooden or metal panels can be an attractive and functional support structure. Attach the blazing star stems to the trellis with ties, especially when plants are young. This method also adds a decorative element to the garden.
Additional Tips for Successful Support
To maximize support effectiveness, consider the following tips:
- Install supports early in the season to avoid damaging mature stems.
- Use flexible ties that won’t cut into the stems as the plant grows.
- Regularly check and adjust ties to prevent constriction.
- Prune back any damaged or weak stems to encourage strong growth.
- Ensure the soil is well-drained and rich in organic matter to promote healthy root development.
Conclusion
Supporting blazing stars for vertical growth is a simple yet effective practice that enhances their beauty and longevity. By selecting appropriate support methods and maintaining them throughout the growing season, gardeners can enjoy tall, vibrant flower spikes that add color and structure to their landscapes.
