Horseradish Roots

It probably wont matter if you have.  They are very hardy and persistant plants to the extent that they can become troublesome.  I have mine tucked away in a far corner for this reason. 

Mine began to sprout at the end of March, although they are in partial shade.  It is a bit late to be planting, but they should be fine if they are lightly watered and firmed in.

In a couple of years you will wonder why you ever worried about them   

Still no sign of anything......
