hello .. we have clubroot, or what we are assuming is clubroot, in three of the beds at our community garden .. these beds hold broccoli and cabbages .. the pictures below show what is happening with the roots .. is this clubroot? .. could it be the effect of transplanting seedlings too many times before planting in the garden? .. if it is clubroot, what could be done to replenish the bed once the brassicas are removed? .. on researching clubroot (minimally) it seems that one now needs to add enough lime to the bed to raise the ph to a sweeter level .. would it then be a good idea to lay down 4" or so of compost, and then dig it in? .. the beds have been rotated .. at the end of the season last year what was thought of as clubroot was found in one bed .. this year it is in three .. how does that happen .. ? .. and interesting challenge presents itself to us, in this learning garden .. any ideas/assistance in this matter would be very much appreciated .. thank you ..
