Where can I find a good container to plant horseradish? The article says to find a pot that will promote 24-36 inch root growth. I haven't been able to find a 24 inch tall container. Please help.
Check you local garden centers and ask for a large growing pot in the size you need.
Also check Ebay, they are often a good source for these items.

I live in Muskoka, Ontario, Canada. If I put my horseradish in containers this fall will it survive our winter?
Your average lowest temperature is -10.5 degrees Celsius (13.1 degrees Fahrenheit). Horseradish is hardy to zone 3 or about -40 degrees F. So it looks like you could grow it in a container. I would still cover it with hay or mulch during January at least.

We have been growing, cultivating and eating our own horseradish for years. When we grate it you can not even take a whiff of it or it because it is so strong. That is the way we like it. We cultivated some in spring and have just dug some up now. All of a sudden we have lost most of the potency. Can you explain why?
I would attribute this to a sulfur deficiency. This plant is not really a high feeder, so standard deficiencies aren't as common. Sulfur deficiencies can go largely unnoticed, though.
The chemical compound, isothiocyanate, is responsible for the "spicy" in this plant. This chemical can only be formed in the presence of sulfur. This can indicate that there is a lack of this in the soil.
Try fixing this with iron sulfate, or wettable sulfur. That should take care of the issue, going forward.

Hi I have a robust horseradish plant in my garden. I read your article on propagation. I will be moving from this house in the spring. I would like to take some horseradish plants with me so I can plant them at my new home. My question is, should I try to cultivate the plants I want to take with me indoors in a pot? Should they be in a cooler place? Cold place? I live in Pittsburgh, PA Thank you
They will do well in container. They will also do fine outdoors in that area, and even becoming invasive. If you would like to take some in container it will do just fine, but at some point you may want to plant it outdoors.

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.

We got this from a neighbor and don’t know what it is or how to cook it?
The problem with the Brassicaceae family is that so many resemble each other. Pinning down an ID will be difficult.
I would ask your neighbor. Since that is the person that gave them to you, I would suspect that they have an idea as to what they are.
My best guess is going to be horseradish leaves.
