I am growing horseradish for the first time; I started it in a gallon container in the greenhouse in December and it has been doing well except aphids. I believe this is because it is ready for a bigger space and I am concerned about putting it out in the gardens now. Our last frost date is not until the end of April. However, even if the foilage died back, it seems it would re-grow when the temperatures were better. I am experimenting and will likely put it out and then if we get another frost or snow, I will cover it with mulch and leaves.
