When conditions favour it in Kraków
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: ≥24°C · dry air ≤50%. 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.
How this compares
Of the 13 locations published here, Kraków ranks 7 for hours favouring this disease in a year.
Fix the cause, not the leaf
No spray will help here. The trigger is soil, water supply, nutrition or temperature, so change the growing condition and judge the result on new growth, not on damaged leaves.
Scout the planting once temperatures pass 24°C, in dry air below 50%.
Not contagious. Nothing spreads from plant to plant here. Neighbouring plants showing the same signs are reacting to the same soil, water or weather, so fix the cause rather than isolating plants.
