Lemon is a fruit tree that loves warmth and humidity, suitable for growing in subtropical regions. However, when winter comes, special attention needs to be paid to its growing environment and maintenance methods to ensure its normal growth and fruit yield. This article will introduce the maintenance techniques for lemon trees in winter.
Reasonable Pruning of Branches
Before winter arrives, it is necessary to prune the lemon tree reasonably, removing withered, diseased, pest-infested, and cross-growing branches, while retaining the main trunk and healthy branches to promote the growth and branching of the tree.
Maintain Suitable Temperature and Humidity
The suitable temperature range for lemon tree growth is 18℃-30℃. In winter, special attention should be paid to whether the indoor temperature is too low. At the same time, maintain the air humidity not lower than 50%. Humidifiers or sprayers can be used.
Control the Amount and Frequency of Watering
Lemon tree growth slows down in winter, so it is necessary to control the amount and frequency of watering to avoid excessive or insufficient soil moisture, ensuring the healthy growth and nutrient absorption of the roots.
Fertilize to Enhance Nutrient Supply
Lemon trees grow slowly in winter and need appropriate fertilization to enhance nutrient supply. Organic or compound fertilizers can be used, about once a month.
Prevent and Control Pests and Diseases
Pests and diseases are prone to occur in winter, so prevention and control are necessary. A combination of physical and chemical control methods can be used, such as regularly cleaning the leaf surface and spraying insecticides.
Avoid Sudden Temperature Changes
The temperature fluctuates greatly in winter, and lemon trees need to avoid sudden temperature changes, especially during the heating season. Pay attention to the use of air conditioners and heaters to maintain a stable temperature.
Observe the Leaf Color
Changes in the color of lemon leaves can reflect their growth status and care condition. It is necessary to frequently observe whether the leaf color is normal, and timely handle situations such as yellowing or wilting.
Prevent Tree Damage
The temperature is low in winter, and lemon trees are vulnerable to damage from ice, snow, wind, and sun. Measures need to be taken to prevent tree damage, such as covering and protecting the tree or reinforcing supports.
Maintain Air Circulation
Poor indoor ventilation in winter can easily lead to diseases and pests in lemon trees. It is necessary to maintain air circulation, which can be done by opening windows appropriately or using an air purifier.
Strengthen Daily Care
Winter is the dormant period for lemon trees, and daily care needs to be strengthened, such as regularly cleaning the leaf surface, trimming dead branches, and clearing weeds.
Pay Attention to Lighting
The daylight hours are shorter in winter, and lemon trees need sufficient light to promote normal growth. Artificial lighting can be used or potted plants can be moved to a location with more sunlight.
Prevent Drought
The temperature is low in winter, and the indoor air humidity is relatively low, making lemon trees susceptible to drought. It is necessary to control the amount and frequency of watering and strengthen misting and moisturizing.
Regularly Repot
Lemon trees need to be repotted once a year. Winter is a suitable time for repotting. It is necessary to choose suitable potting soil and container size to promote its growth.
Control Indoor Temperature
Lemon trees grow slowly in low-temperature environments, so it is necessary to control the indoor temperature to avoid the effects of excessively low or high temperatures on its growth.
The key to caring for lemon trees in winter lies in controlling temperature and humidity, regular pruning and fertilization, preventing and controlling pests and diseases, and maintaining air circulation. Only by paying comprehensive attention to all details can the normal growth and fruit yield of the lemon tree be guaranteed.
