Q.Harvesting Potted Horseradish
Hi! This is my 1st time planting horseradish. I planted it in a pot, actually a 32 gallon trash can. I drilled drainage holes in the bottom and placed pea gravel in the bottom for better drainage…what I would like to know? I planned on bringing the trash can into our unheated garage over winter and harvesting in the spring. Should I do that or leave it outside? The trash can does have lid I can use. Thank You, Dan

This plant will be fully hardy in your area. No extra care is needed, although, when you harvest you will want to leave some portions of root. This will be next year's crop.
