We have discovered clubroot in our brassica raised beds. The brassicas have been removed and garbaged. We know that it will be a long time before we can plant brassica s but can we plant other crops in these beds next spring? We've sown a cover crop to try to replenish the soil and understand that we should be limeing it.
Yes, you can plant any other non-brassica plants in the beds. Aim for a pH of about 7.5 when you add the lime.
I've been able to eliminate clubroot from my garden with a 7 year rotation plan, but 5 years may be enough.
Yes, I've heard of "cooking" the soil. It's usually called "soil solarization", and there is lots of information about it on the Web. Try googling it or looking it up in Wikipedia. I think that clear plastic is preferred, and it's probably too late to try it this year in Victoria, BC. It would have been very effective back in July.
