The FAAGROH agronomist explains why some species suffer more from low temperatures and dry climates
OR winter have arrived and low temperatures also become great bad for the “health” of plants, which are fundamental for the environment. More than just decorative objects, these vegetables are made up of 80% waterfactor influencing its growth, development and reproduction. The cold, in turn, ends up affecting their fluids, freezing them and consequently killing their cells..
“In colder climates, where frost does occur, the thin film of ice that forms as the temperature drops ends up covering the entire plant and causes solar radiation amplifies its effects, burning the surface“, explains Ronan Pereira Machadoagronomist and director of the agronomic engineering course at the Faculty of Agribusiness of Holambra (FAAGROH), at the UniEduK Group.

Even during the winter, according to Ronan, most plant species go into a period of dormancy. That is, he has his metabolism reduced to withstand the cold and winds of the season, preparing for the intense metabolic activity that will arrive in the spring.
The minimum temperature that a plant can withstand varies according to the species. The Mediterranean ones, for example, tolerate between 10 and 12ºC; while the tropical ones from 20 to 22ºC. Species that are well adapted to the cold can resist down to -5ºCwithout presenting any problems.
Among the plants that suffer most from the cold are heliconias, bromeliads, clusias, St. George’s sword, succulents and cacti.. “These are evergreen species from the tropical region, which have broader leaves and maintain constant metabolism and development throughout the year, regardless of the season,” explains FAAGROH agronomist. “But there are also more hardy ones, such as azaleas, camellias, lavender, hydrangeas, roses and tulips.
But how to take care of plants in this period of low temperatures? Even in the bitter cold, the engineer ensures that you can keep that houseplant alive and healthy all the time. For this, special care is required. Check out the 5 tips below!
In which part of the house should plants be left in winter?
“Potted and hanging plants can be placed inside the house, and those that need the sun should be close to windows. However, not too close, as extreme temperatures can leave windows very cold, damaging plants,” she advises. Ronan.
When to water plants in winter?
The right time to water them is in the morning. They will thus have all day to evaporate the water that is absorbed, preventing the accumulation of humidity during the night and preventing the proliferation of fungi.
Can I fertilize plants in winter?
The orientation is not to carry out fertilization, because the moment is rest for the plants. Fertilizer will stimulate germination and cause more wear. The moment is ideal to carry out the terrain correction. Fertilize only those most needy, sick or in bloom, favoring organic products so as not to cause toxicity and greater acidity to the soil.
Do I need to clean and spray plants in winter?
Winter is the period in which the plants need cleaning pruning and, after having carried out the service, spraying with a fungicide, which should reduce the appearance of diseases.
Do plants need sun in winter?
Finally, the FAAGROH agronomist recommends removing the yellowed leaves and dry and badly formed branches, which will favor the penetration of the sun’s rays between the branches.
