When conditions favour it in London
Hours in an average month when conditions meet every threshold this disease declares (2021–2025). Faded bars are months the database does not list the problem as active.
This disease's thresholds: 25–37°C · humidity ≥70%. Every hour in the archive was tested against them.
These come from the ERA5 reanalysis on a roughly 9 km grid, so they describe the area rather than your plot. A shaded, sheltered corner holds leaf wetness longer than open ground, so conditions there can favour it more often than the figure suggests. This is a climate profile, not a forecast — the panel above carries the current risk.
Remove affected material now
Take out the affected leaves, shoots or whole plants before the next wet spell, bag them as you cut, and wash your hands and tools before touching healthy plants.
Scout the planting while temperatures hold between 25°C and 37°C, with humidity above 70%.
Tools, hands and cuttings. It travels on secateurs, stakes, gloves and propagation material. Work through healthy plants first and disinfect tools between plants.
