Hi, I bought my horseradish plant as a baby from Bunnings for about $3.50. Second season now and I have about 7 plants in the one spot and it's GROWING... Wish I had have read that it takes over BEFORE I planted it in the ground!

I live in inner city Sydney and planted horseradish in potting mix in a pot at the back of the pot section on my west-facing balcony in about June (?). I've pretty much left it alone except for an occasional water if it's been particularly dry. The leaves have grown well - they were pretty lush before though I've noticed now that they're a bit torn - whether this is from an insect or from a few hailstorms I'm not sure. Thing is... I have no idea when to harvest them. How do I know if they're ready to be pulled up and used? And can I just pull up one leaf/plant and leave the rest in the pot? Also, I'm experimenting now but I really want to have some fresh root available in March/April next year. Do I have to replant at a particular time? Can I leave the current plants in the pot until then? etc
