The city of Ostrava has initiated the fifth stage of a systematic program to combat European mistletoe, a semi-parasitic plant that threatens urban greenery by absorbing nutrients and water from host trees. This phase involves treating approximately 644 to 650 trees across the districts of Moravská Ostrava and Přívoz, Hrabová, and Ostrava-Jih.

Scheduled to begin during the upcoming vegetation dormancy period and continue through the end of next year, this stage is estimated to cost 4.8 million CZK, excluding VAT. The work is being carried out by the municipal company Ostravské městské lesy a zeleň and includes parasite removal and health pruning to ensure tree safety and condition.

Since the program began in 2022, specialists have treated nearly 1,700 trees at a total cost of approximately 12.5 million CZK. The initiative targets trees in parks, street rows, housing estates, and municipal cemeteries where replacement is difficult due to spatial constraints.
