Can hibiscus survive in the cold winter? (Impact of cold climate on hibiscus and protection methods)

Abstract:As a popular and beloved flower, the hibiscus has been widely planted and appreciated for a long time. However, in the cold winter, can it survive? This is a question that has attracted much attention. Let's find out together. I. Growth Habits of the HibiscusThe hibiscus prefers a warm and humid climate, with the most suitable temperature for growth being between 18°C and 26°C. In the cold winter, the temperature drops sharply, so what impact will this have on the hibiscus?II. Performance of the Hibiscus in WinterIn winter, the leaves of the hibiscus will gradually wither, and the flowers will no longer bloom. This is because in low-temperature environments, the hibiscus cannot carry out photosynthesis and growth normally.III. Will the Hibiscus Freeze to DeathIn low-temperature environments, the roots and stems of the hibiscus can be frost-damaged, or even freeze to death. If the temperature remains below freezing for a long time, it is very difficult for the hibiscus to survive.IV. The Harm of Cold to the HibiscusCold weather makes the hibiscus's cell tissues fragile and susceptible to damage. Moreover, if the hibiscus freezes to death, it will affect its growth and flowering the following year.V. Measures to Protect the HibiscusIn winter, we can take some measures for the hibiscus, such as covering it for warmth, pruning, and strengthening its care, to protect it from the effects of cold weather.VI. Methods for Covering and Keeping WarmCovering for warmth is one of the most common methods to protect the hibiscus. You can cover the hibiscus with straw mats, burlap sacks, straw, etc., to effectively prevent cold damage.VII. Principles of PruningWinter pruning can help the hibiscus to be better trimmed and shaped, while also reducing the impact of cold weather on the plant. However, pruning should be done according to principles; do not over-prune, otherwise it will affect growth.VIII. Methods for Strengthening CareIn winter, we can strengthen the care of the hibiscus, for example, by watering it moderately, fertilizing it, and pruning it. These measures can help the hibiscus better adapt to the cold environment.IX. Choosing Suitable VarietiesSome varieties of hibiscus are more cold-tolerant and can adapt to low-temperature environments, such as the rose of Sharon. When choosing to plant hibiscus, you can consider selecting these suitable varieties.X. Pay Attention to Maintaining VentilationWhen covering for warmth, pay attention to maintaining ventilation to avoid excessive heat causing suffocation and heat damage to the plant. At the same time, clean up fallen leaves and weeds in time to keep the soil moisture appropriate.XI. Not Suitable for Transplanting During Frost PeriodThe frost period refers to weather below 0°C. Transplanting during this time can easily damage the hibiscus, or even cause it to die. It is best not to transplant during this time.XII. Pay Attention to Wind Protection in WinterCold weather is often accompanied by strong winds, and the hibiscus is easily blown over. In winter, pay attention to wind protection, you can use stakes, plastic ropes, and other methods to secure the plant.XIII. Clean Up Snow Piles in TimeDuring the snowy season, clean up snow piles in time to avoid pressure and damage to the plant. You can use tools like snow blowers or shovels to clear the snow.XIV. Pay Attention to Moisture Retention for the PlantIn low-temperature environments, the soil can easily become dry, so pay attention to maintaining the plant's moisture. You can water it moderately or spray water to keep the soil appropriately moist.XV. In summary, the hibiscus faces many difficulties and challenges in the cold winter. But as long as we take the correct protective measures, we can help it get through the winter smoothly and continue to bring us beautiful flowers in the following spring.
