Attention Gärtner: Froat of frost during the ice saints in May 2025!

Österreich - The ice -horny are a well -known phenomenon that occurs from May 11th to 15th and is a critical time for many gardeners in Central Europe. During this period, cold burglars and frost can be expected, which is a threat, especially for sensitive plants. The ice saints are also connected to five Catholic saints: St. Mamertus (May 11th), St. Pankratius (May 12th), St. Servatius (May 13th), St. Bonifatius (May 14) and the Cold Sophie (May 15) [Kosmo] reports that these days are historically considered particularly frost.

hobby gardeners should be well equipped, because young plants are susceptible to frost damage that can endanger not only the plants, but also the yield of gardeners. Human rules of farmers, as "before night frost you are never sure until Sophie is over", illustrate the uncertainty associated with late frosts [Echo24]. In fact, it is advisable to put frost -sensitive plants such as tomatoes or zucchini outdoors after the ice saints.

causes and forecasts

The May frosts often arise from different heating speeds of land and water areas. Cold air masses from the polar regions can penetrate south and cause nightly temperature reductions. In Austria, however, there is an interesting development: the nightly ground frost during the ice saint has become less common in recent years. Meteorologists attribute this to climate change and the increased average temperatures [Kosmo].

A milder cold period for the ice saint 2025 is predicted without extensive frost events. The temperatures should increase until the first weekend in May, followed by a slight drop in temperature, which will not have drastic frost consequences [Echo24]. Nevertheless, it is important to keep an eye on the weather conditions, since many gardeners have often not experienced frost during the ice saints in recent years, but storms with storms and hail [Fryd].

peasant rules and measures

• st. Mamertus: frosty nights endanger young plants.
• st. Pankratius: frost at night can damage plants; Nice weather could bring good wine.
• st. Servatius: inconsistent weather; Cold east wind endangers flowers.
• st. Bonifatius: Last cold wave - risk of frost damage in early summer plants.
• cold sophie: ends the ice saints; After her the planting time is safe.

gardeners should still prepare for the risk of frost and, if necessary, take protective measures such as fleece or foil for young plants. Experts recommend wind -protected locations and garden planning based on natural principles [Fryd]. In addition, frost damage usually only shows effects a week after a frost event, whereby often only the superficial parts of the plants are affected.

Overall, it can be stated that the ice saints are not only a traditional topic, but also falter through climate change. The exact results of the weather are regionally different and require increased attention and adapted measures to protect sensitive plants.
