Ralstonia solanacearum can overwinter in plant debris or diseased plants, wild hosts, seeds, or vegetative propagative organs (other germplasm) like tubers. The bacteria can survive for a long time in water (up to 40 years at 20–25 °C (68–77 °F) in pure water), and the bacterial population is reduced in extreme conditions (temperature, pH ...
The more consistently you can keep these soil factors, the better your plants will be. Remember, it is also best to somewhat mimic rainfall patterns to wean plants off excessive moisture.
