I harvested my first year’s growth of horseradish last fall, and let the smallest roots stay in the ground over the winter. This year I have a luxuriant growth of new small plants. They definitely spread very fast! I expect in 2-3 years they’ll be “invasive” hehe.
They are still in the same spot where they were last year, but since I did a crop rotation they are now in the “brassicas bed” instead of the “roots bed”.
kbaichtal's Horseradish Care Instructions
Ensure you have enough space in your garden for this plant - Horseradish is known for growing to a height of approximately 60.0 cm (that's 1.95 feet in imperial).
Your garden has full sun light - a partial sun position will ensure your plant thrives.
Try to apply water fairly sparingly.
