Frequently Asked Questions
Why does horseradish need deep soil for root development?
Why does horseradish need deep soil for root development?
Horseradish forms a deep taproot, so loose soil with sufficient depth gives the root room to develop. Compacted soil can restrict root growth and make harvesting more difficult.
Can horseradish be grown in a raised bed?
Can horseradish be grown in a raised bed?
