Yes, horseradish can produce viable seeds, although seed production and fertility can vary between plants. Root cuttings are the traditional and more common propagation method because they establish more reliably and help maintain the characteristics of the parent plant. If growing from seeds, use fresh, viable seeds and follow the supplier's sowing recommendations.
Horseradish requires an extended growing period to develop substantial roots. Plants started from seed generally take longer to establish than those grown from root cuttings. Root size and harvest readiness depend on the variety, climate, soil depth, and growing conditions. Allow the plant to establish a healthy root system before harvesting.
Yes, horseradish can be grown in a large, deep container with drainage holes and fertile, well-drained growing medium. Container growing is particularly useful because horseradish spreads through underground roots and can become difficult to control in open garden beds. Check containers regularly and remove unwanted root growth to keep the plant manageable.
