I had none in last summer's harvest, which was companion planted with marigolds; and had loads on this winter's harvest which had no companion planting...so you can guess what I am also going to recommend.
I've also heard that rhubarb stalks under brassicas are supposed to help deter pests [and brassicas seem to get the most out of any crop] so I bought a rhubarb crown last weekend purely for that purpose.
I also plant flax with my brassicas; they attract good bugs in to hopefully munch the bad ones...but truth be told I think they are a gorgeous flower and don't care if they provide any benefits - they are so lovely.
I'm also told that garlic and chilli spray can help, but when I tried that the nozzle go bunged up; so I'm using water soaked in cloves and chillis rather than anything whizzed up this year. Read that in my no-dig book, and like the idea of the broccoli coming ready flavoured. |
