How To Take Care Of Dwarf Lemon Tree

Knowing how to take care of a dwarf lemon tree properly is essential in order to reap its many benefits. Dwarf lemon trees need protection from frost and may require bring brought indoors or, in the alternative, protected by fabric or other such covering to survive temperatures below 10°C (50°F). Additionally, upon purchase, it’s advisable to prune off any dead, diseased, or weakened branches, which can be done quite easily thanks to the small size of the tree. Here are a few more tips on how to care for this type of tree.


A dwarf lemon tree usually needs to be kept in an area with abundant light, ideally a south-facing window or an outdoor area with direct sunlight for a majority of the day. If the tree is kept outdoors, ensure that it is sheltered from wind so it doesn’t dry out. Trees that receive too much or not enough light lose their leaves.


The soil your dwarf tree is planted in must be slightly acidic and well-draining. To achieve this, add some compost and sand to the soil and ensure it is not waterlogged. Additionally, to avoid root damage, perform regular soil checks with a finger to identify any dry and wet spots. Too much water can lead to root rot.


Dwarf lemon trees must be watered regularly and deeply. Normal household tap water is fine but orchid, rain or distilled water can be used to achieve slightly acidic soil, suitable for lemon trees. Furthermore, the soil should be damp, but not soggy. If the upper surface of the soil is dry, it’s time to water.


Feeding your lemon tree with organic compost or fertilizer every 3-4 weeks throughout the summer months helps to promote good growth, fruit production and excellent colour. You can also use a balanced liquid fertilizer, but be sure to read the label for correct dosage and method of administration.


Mealybugs, aphids and spider mites are some of the more common pests that dwarf lemon trees can suffer from. To rid the tree of them, spray the affected area with a solution of diluted Castile soap in water or apply neem oil. Additionally, you can introduce beneficial organisms, such as ladybugs, to help keep pests away.


Dwarf lemon trees may develop fungal disease such as powdery mildew or fruit rot. If this happens, you can use a fungicide such as copper sulfate or general-purpose fungicide. To prevent these diseases, ensure the tree is exposed to plenty of light and water is given directly to the soil so that the foliage doesn’t come into contact with it.

Prune And Harvest

Dwarf lemon trees need regular pruning to keep them in an ideal shape, produce more flowers and fruits, as well as provide better air circulation. Prune the lemon tree in early spring before it begins to bloom. To harvest the lemons, let them ripen on the tree, then cut them off with a sharp pair of secateurs.

Container Size

When shopping for a dwarf lemon tree, it’s important to consider what size of container or pot is needed. The tree’s pot should correspond to its size; as the tree grows, the pot should be changed. Be sure to use quality soil and a pot with adequate drainage holes. Additionally, dwarf lemon trees do not need repotting every year.

Harvesting Fruit

Once the lemons start to appear, it’s important to pick the fruit regularly when it is ripe. If left on the tree for too long, the fruit tends to dry out and won’t taste as good. As with pruning, use sharp secateurs as this will limit damage to the tree and make for a cleaner cut.

Disease Control

Control of fungal diseases in a dwarf lemon tree is important for it to remain healthy and productive. Fungal diseases such as leaf curl, citrus canker and black spot can be managed by pruning unhealthy branches and leaves, as well as spraying the tree with appropriate fungicides. If you notice any of these diseases, it’s important to act quickly and take steps to prevent the spread of the fungi.

Pest Control

Pests such as aphids, mealybugs and spider mites can target a dwarf lemon tree. To keep them at bay, use organic spray solutions as well as introducing beneficial insects, such as ladybugs and lacewings, to the garden. Additionally, ensure you keep the tree well-watered, with limited dampness around the tree.

Fertilizing Dwarf Lemon Tree

Regular fertilizing of a dwarf lemon tree is important for it to remain healthy and produce good fruits. A fertilizer that is high in nitrogen and low in phosphorus is generally recommended and should be applied during the growing season, typically every 3-4 weeks. Additionally, mulching around the tree can also help to provide vital nutrients for the tree.
