FAQs: Frequently Asked Questions

How tall do Calico Asters grow?

 Calico Asters typically reach a height of 2 to 3 feet, with some varieties occasionally reaching up to 4 feet under optimal growing conditions. Their height makes them ideal for mid to back borders in gardens, providing a beautiful backdrop of delicate blooms.

Can Calico Asters grow in containers? 

Yes, Calico Asters can thrive in containers if provided with adequate space and proper care. Choose a container with good drainage, at least 12-16 inches in diameter, and use a well-draining potting mix. Ensure they receive sufficient sunlight and water regularly, allowing the soil to dry out slightly between waterings.

How do I prevent mildew on my Calico Asters? 

To prevent mildew, ensure your Calico Asters are planted in a location with good air circulation and receive adequate sunlight. Avoid overhead watering and instead water at the base of the plant to keep foliage dry. If mildew appears, promptly remove affected leaves and consider using a fungicidal spray according to manufacturer instructions.

Are Calico Asters deer resistant? 

Yes, Calico Asters are generally deer-resistant due to their bitter-tasting foliage. While no plant is completely deer-proof, Calico Asters are less likely to be browsed by deer compared to other garden plants. They make a suitable choice for gardens in deer-prone areas where minimizing deer damage is a concern.

What is the best way to harvest seeds from Calico Asters? 

Harvest seeds from Calico Asters by allowing the flower heads to dry completely on the plant. Once dry, gently crush the heads to release the seeds. Collect the seeds in a paper bag or container, ensuring they are stored in a cool, dry place until ready for planting. Properly stored seeds can remain viable for several years, allowing you to propagate new plants seasonally.
