I know most people treat this as a weed but I'm growing a 2year old plant (from rootstock) in a large pot. Thing is it seems to be giving all the signs of bolting. Suddenly has produced a long slender stem rather than its normal bushy nature with flower buds on top. Is this normal? Should I cut off the bolting stem or do I have to let it run to produce flowers. My intention is to eventually plant it out in a quiet area of my lottie but want to get it established first. Any ideas?
the romans used horseradish to hold the sides of roads together, ( like we use willow) any old bit of root with 2 ends will grow!! let it seed if you like, or cut of the flower spike to encourage more root.
the best thing for this thug of a plant is to plant it in a 45 gal drum, you can then just push it over to harvest the roots;)
No idea what sort of weather you have had recently but that does sound as though it got dry and panicked.
Cut the stem off and make sure it remains moist
