Crop Rotation
Very little is known about how Rhodiola rosea affects soil nutrients. In addition, it is not known if the plants leave toxins in the soil which might prevent reusing the soil for future crops of Rhodiola. However, it is prudent to manage your crop rotation, and grow alternative crops for one or more years in your Rhodiola fields.
Since Rhodiola rosea is a perennial and a succulent, grain crops (wheat, oats, barley) may work well to maintain control of weeds. In addition, a green manure can be planted prior to your next crop of Rhodiola rosea.
As Rhodiola Growers of Canada learns more about Rhodiola nutrition and possible toxins, we will add this information to the Knowledge Base.
