What a lemon tree needs in winter
The lemon tree(Citrus limon) is a fruit tree that fears frost and low temperatures. So, it’s necessary to protect your fruit tree in winter. Here are a few tips:
Ideal temperatures for lemon trees
- Lemon trees have difficulty with temperatures below 0°C, and excessive cold can lead to leaf loss or tree death.
- The lemon tree needs a winter resting period with temperatures between 5°C and 12°C to promote fruiting and flowering.
Light and humidity requirements
- Lemon trees are light-loving, and need plenty of sunlight, even in winter.
- It appreciates a certain amount of ambient humidity, as overly dry air can encourage attacks by mites and other parasites.
The right location for your lemon tree in winter
In regions with mild winters, lemon trees can be kept in the open ground, but must be protected from the cold. In regions with harsher winters, the lemon tree is best potted, as it can be sheltered indoors during the winter months. Here are a few tips:
Lemon trees in the ground:
- Choosing a location sheltered from cold winds, close to a wall is a good alternative, as it will reflect the sun’s light and heat.
- Give preference to well-drained soil, as stagnant humidity and frost can cause root rot.
- If frost is forecast, protect the base of the tree with thick mulch(straw, bark, dead leaves) and wrap the trunk and branches in a winter veil to preserve heat and prevent the bark from bursting in the frost.
Potted lemon trees:
- Place the pot on a stand with wheels for easy movement.
- As soon as temperatures drop below 5°C, bring your lemon tree indoors.
- The temperature should remain stable at around 10°C, and the air should not be too dry.
Proper care for your lemon tree
Now that your lemon tree is in a good spot in winter, all that’s left to do is look after it. Here’s how:
Watering and fertilizing
- In winter, the lemon tree needs less water, but it’s important to keep the soil moist. Water moderately, and make sure the water doesn’t stagnate.
- For fertilization, it’s best to wait until early spring, as lemon trees are at rest in winter. Choose a special citrus fertilizer.
Pruning and preventive care
- Lemon trees are generally pruned after the fruit harvest, in autumn or winter. This involves removing dead, diseased or intersecting branches, to encourage the circulation of light.
- Inspect your lemon tree regularly for pests(mealybugs, aphids, mites), and treat as necessary.
Cold-hardy lemon varieties
Not all lemon trees are equal when it comes to cold weather, and some varieties are more resistant than others. So, in a region with harsh winters, choose :
- Meyer lemon(Citrus x meyeri)
Native to China, the Meyer lemon is a hybrid variety that can withstand temperatures down to -10°C.
- Yuzu lemon(Citrus junos)
The Yuzu lemon is a very cold-hardy Japanese citrus, capable of withstanding temperatures down to -12°C. It produces highly fragrant fruit.
- Ponderosa lemon(Citrus x limon ‘Ponderosa‘)
The Ponderosa lemon is an American variety that can withstand temperatures down to -6°C. It produces large, juicy, fragrant fruits that are less acidic.
Caring for your lemon tree in winter isn’t too complicated, all it takes is a little care and vigilance. A lemon tree that is well protected and cared for during the cold season will produce beautiful lemons more easily, not to mention the pleasant fragrance that this tree also produces.
