Do you know the cultivar/ species ?
Do you know whether they are 1 yr. or 2 yr. old roots ?
Generally the larger and older roots will yield a harvestable crop sooner , provided the soil has been adequately prepared (rich in organics,leaves, and long term release nitrogen).
Don’t know any of that stuff, other the it’s Martha Something. It was bought on a whim.
We will see if it even comes up!
