Suddenly cold weather conditions

Region: North Europe

Last week it went freezing at night. When these temperatures persist, it becomes dangerous for the cool-grown crops, such as e.g. Primula acaulis Paradiso and Ranunculus Sprinkles.

Despite these low temperatures, it is usually still sunny during the day, but the first rays of the sun are intense for the plants after a few dark months. The leaves warm up relatively quickly, but the pot bulb remains in temperature, causing the supply of moisture and nutrients from the roots to stagnate. Plants then hang limp or withdraw their moisture from the older leaves, making them yellow.

We advise to keep the screen installation closed during the day in frosty weather with strong irradiation to help the crop. We also advise you to keep a close eye on the moisture condition of the plants.
