Here are some care tips for Kalimeris incisa 'Blue Star':

1. Sunlight: 'Blue Star' thrives in full sun to partial shade. It prefers at least 4 to 6 hours of direct sunlight each day for optimal growth and flowering. Plant it in a location with ample sunlight exposure.

2. Soil: 'Blue Star' prefers well-draining soil that is fertile and moist. It can tolerate a range of soil types, including sandy or clay soils, but it performs best in soil that retains moisture without becoming waterlogged. Improve the soil's fertility and drainage by incorporating organic matter, such as compost or well-rotted manure, before planting.

3. Watering: Keep the soil evenly moist, especially during the plant's establishment period. Water deeply and thoroughly when the top inch of soil becomes dry. Avoid overwatering, as it can lead to root rot. Mulching around the base of the plant can help retain moisture and reduce weed growth.

4. Pruning: 'Blue Star' requires minimal pruning. Deadhead the faded flowers to encourage continuous blooming and to maintain a tidy appearance. In late winter or early spring, you can cut back the plant to a few inches above the ground to rejuvenate it and promote fresh growth.

5. Fertilization: Apply a balanced slow-release fertilizer in early spring to provide a light nutrient boost. Follow the package instructions for the appropriate dosage. Additionally, you can top-dress the soil with compost or organic matter each year to improve soil fertility and overall plant health.

6. Disease and Pest Control: 'Blue Star' is generally resistant to common pests and diseases. However, it's always a good idea to monitor the plant for any signs of issues, such as aphids or powdery mildew. If necessary, apply appropriate organic or chemical treatments as recommended.

7. Winter Care: 'Blue Star' is hardy and can tolerate cold temperatures. It generally does not require any special winter care. However, in colder regions, applying a layer of mulch around the base of the plant in late fall can provide some insulation and protect the roots from freezing temperatures.

By following these care tips, you can ensure that your Kalimeris incisa 'Blue Star' thrives and produces an abundance of blue flowers. Enjoy the attractive foliage and long-lasting blooms of this lovely perennial in your garden or landscape.
