Marina, I've been giving quit a lot of horseradish away over the past few months but the parent plant can still provide another one. What I do is pot the plant and allow it to stay there until it has settled and is producing new leaves then maybe another week or two which usually makes it fine for transporting, now it won't be full grown so whilst the root won't be suitable the leaves will. Would you like me to do that? Oh by the way I'm in Logan City. Roy

I kept the rootpieces in water through winter and spring in a cold glasshouse and they were rooting and making leaves. In Nov. or Dec. I planted them in a deep bucket and they are growing beautifully. I'll harvest after the first frost, if anybody wants pieces, pls contact me [email protected]. I'm in Elsburg, Germiston,Gauteng.

Margaret, I haven't found the perfect time, the size of the leaves don't tell me anything. Last week I did use some, just scraping away surrounding soil and seeing the thickness of the root helped, the root was fairly thick, about the same as two fingers plus a little more. Getting it out is the hard part, the roots go down a long way so I cut the amount I needed and replaced the soil. Be careful if you do this because the root is very strong, a serrated knife worked o.k
