How can I determine when horseradish rhizomes are ready to harvest. Time is a bit out of whack because it took ages for it to take. Currently the outer leaves are about 45cm long 15 cm wide clear healthy emerald green colour with many smaller leaves inside them. I planted a single piece of 5 cm rhizome in a 30 ltr veg bag in March this year. Only started going about a month ago but is going very well now.

My guess would be you have picked it too early or your soil is a bit poor. Read the notes here about growing it. Or google how to grow it.
