Good and bad companions of Turnip
Very good neighbours
Subterranean clover
Subterranean clover as an undersowing cut flea beetle damage by 66 percent in trials.
Good neighbours
Crimson clover
The clover's scent disrupts the orientation of cabbage root fly and cabbage white.
Phacelia
Phacelia does not host brassica pathogens and lowers clubroot pressure on the plot.
Shallot
Young turnips can be grown between rows of shallots and harvested early.
Evidence quality: good
Evidence: Specialist book
Reasons:
- Practical tip for this pair
Spring onion
Spring onions and turnips can be sown thinly mixed together. Both are harvested young without disturbing the others.
Evidence quality: good
Evidence: Specialist book
Reasons:
- Practical tip for this pair
White clover
Flowering white clover undersowing confuses the cabbage white and reduces egg laying.
Bad neighbours
Mustard
Both are brassicas. Clubroot resting spores survive up to 20 years in the soil, so a 4 to 5 year break is needed.
