Growing a collection of Blazing Stars (Liatris spp.) can be a rewarding experience for any gardener or plant enthusiast. One of the most effective methods to expand your collection is through division. This technique allows you to propagate healthy plants and increase your garden’s diversity with minimal cost.
Understanding Blazing Star Division
Division involves separating a mature plant into multiple parts, each capable of growing independently. For Blazing Stars, this process is best performed in early spring or late fall when the plants are dormant. Proper timing ensures the divisions establish well and thrive in their new locations.
Why Divide Blazing Stars?
- Increases the number of plants in your collection
- Revitalizes older, overcrowded plants
- Enhances flowering and overall plant health
- Allows for sharing with friends or community gardens
Tools and Materials Needed
- Garden spade or sharp knife
- Garden gloves
- Pruning shears
- Rooting hormone (optional)
- Watering can or hose
Step-by-Step Division Process
Follow these steps to successfully divide your Blazing Star plants:
1. Prepare Your Tools
Ensure all tools are clean and sharp. Wear gloves to protect your hands from plant sap and dirt.
2. Water the Plant
Water the plant thoroughly a day before dividing. Moist soil makes it easier to extract and divide the roots.
3. Dig Around the Plant
Use a spade or garden fork to carefully loosen the soil around the base of the plant. Dig deep enough to lift the entire root ball.
4. Extract and Divide
Gently lift the plant from the ground. Shake off excess soil to expose the roots. Use a sharp knife or pruning shears to divide the root ball into smaller sections, each with roots and shoots.
5. Prepare Divisions for Planting
If desired, dip the cut ends in rooting hormone to encourage root development. Plant each division in prepared soil, spacing appropriately for mature size.
6. Water and Mulch
Water the newly planted divisions thoroughly. Apply a layer of mulch around the base to retain moisture and suppress weeds.
Post-Division Care
Monitor the divisions regularly, especially during the first few weeks. Keep the soil moist but not waterlogged. Fertilize lightly if necessary to promote growth.
Tips for Successful Division
- Choose healthy, mature plants for division
- Divide during the plant’s dormancy period
- Ensure each division has enough roots and shoots
- Label new plants to track different varieties
- Be gentle to avoid damaging roots
By following these steps and tips, you can effectively multiply your Blazing Star collection through division, creating a vibrant and diverse garden filled with these striking native flowers.
