Like me, you might have come across old, shrivelled looking ginger in the boxes displayed at supermarkets. You would have carefully gone through chunk after chunk hoping to find that one bright spark amongst the weary looking ones and finally settle for the least offensive of the lot. So why not just grow your own as it is so easy. Mine looks shiny and fresh and when you slash a small piece off the chunk, the juice literally oozes out.
To ensure you have a fresh supply all the time, harvest only what you need. Growing ginger in a pot is ideal because if you have the space indoors you can just carry it inside and need not bother with building a covered outdoor unit for it.
