How often do I replace the soil in my greenhouse to prevent tomato blight?

Our Advice:

Tomato and potato blight are both air-borne fungal infections, so changing the soil will make little difference. In the greenhouse, consider using tomatoes, peppers or aubergines grafted on to resistant rootstocks to avoid soil-borne pests and diseases.
