Work out your climate from the BLUE TAB Climate Zones at the top of the page. Go to the Horse Radish page, set the climate zone to your climate - TROPICAL. The recommended planting time is in the planting calendar.

Hello Daisy, I need horseradish root for purpose of making a tonic. I could do with about 1-2 Kg. Can you assist ? I inquired with Gardenate, and followed up on your comment. I live in Midrand, betweenJjoburg and Pretoria. Thanks. Sincerely, Mike Habib
