The assessment of health state of broadleaf shrubs was carried out in 2008–2009 in three public gardens of Poznań city: Wilson’s Park, Sołacki Park and Raszyński Park. Withering was observed on many plants in 2008 as result of a long-lasting drought. In the summer and autumn of 2008–2009 the following powdery mildews were found: Microsphaera berberidis on Mahonia aquifolium, M. hedwigii on Viburnum lantana, Podosphaera clandestina on Amelanchier spicata and Oidium sp. on Spiraea japonica. Rust caused by the fungus Cumminsiella mirabilissima was also detected on trailing mahonia. In rainy year 2009 the anthracnose was found on shrubs of snowberry (Symphoricarpos albus). In general, the health state of monitored shrubs in the public gardens of Poznań can be regarded as good.
