The cabbage has left the garden bed, but its “curse” in the form of clubroot remains.
The fungus Plasmodiophora brassicae survives in the soil for up to 7 years, affecting all cruciferous plants.
German gardener Thomas Müller described the nightmare in his blog Bio Garten:

“After cabbage I planted radishes – the roots turned into rot!”
What should not be planted after cabbage:
- Radish, radish, rutabaga.
- Mustard, arugula.
Salvation:
- Sow lupine or phacelia - they suppress fungus.
- Add lime to the soil (200 g per 1 m²).
Advice from agronomist Oktyabrina Ganichkina :
“Plant tomatoes after cabbage – their roots secrete solanine, which kills clubroot spores.”
