Although thermometers may locally show 4 degrees Celsius, due to heavy cloud cover the temperature will not drop below zero.

Wednesday night will be slightly cooler. Then, in the northern voivodeships, values ​​of the order of 0-2 degrees C are expected. In the center of the country it is expected to be about 4-6 degrees C, and in the south – 6-10 degrees C.

How to protect plants on the balcony

In an interview with tvnmeteo.pl, Dr. hab. Julita Rabiza-Świder, professor at the Warsaw University of Life Sciences (SGGW) from the Independent Department of Ornamental Plants at the Warsaw University of Life Sciences, said that the night from Monday to Tuesday will not pose a threat to balcony plants. On Wednesday, the risk will be slightly greater, especially in the case of plants decorating our terraces and those located closer to the ground.

Some plant species may be sensitive to the night cold, e.g. potato plant – a plant that is gaining more and more fans, producing beautiful, large leaves and hanging shoots. The expert added that low temperature may also pose a danger to freshly planted plants previously grown in the greenhouse.

To protect plants from the cold, it is not always necessary to take them from the balcony, especially on higher floors. Just cover them with agrotextile or move the pots or boxes against the wall and place them closer to each other, which will provide them with sufficient protection. Only in areas at risk of negative temperatures is it worth hiding plants growing near the ground, especially when they are planted in pots.
