Lemon trees are a common sight in Australian backyards, with Eureka, Lisbon and Meyer being the most common varieties grown. These trees, which can grow up to 30 feet tall, thrive in warm climates and prefer slightly acidic, well-drained soil. They can be planted at any time of year in these climates, but in colder regions, it's best to plant in spring to protect the trees from late frosts. Lemon trees require full sunlight and regular watering, and with the right care, they can provide a plentiful crop.

Lemon tree varieties in Australia
Lemon trees are a common addition to Australian backyards. The three main varieties grown in Australia are Eureka, Lisbon, and Meyer. These varieties can be grown in most climate areas of Australia, except for colder climates like Melbourne and Tasmania, where they are susceptible to frost damage.
The Eureka lemon tree is a large tree, growing to around 4 metres in height, and is virtually thornless. It produces its main crop in winter, with smaller crops in spring and summer. The fruit has relatively few seeds and is a good choice for gardens accessible to children and pets.
The Lisbon lemon tree is more cold-tolerant than the Eureka variety but does contain thorns, and its fruit tends to have more seeds. It produces its main crop in winter, with the fruit growing on the inside of the tree, protected from the wind. Lisbon trees have denser foliage and a more upright form, and they can grow to between 3 and 4 metres tall.
The Meyer lemon tree is smaller in size, reaching around 2 metres when grown in the ground, making it ideal for growing in pots. Meyer lemons have a reduced acid content and a more orange rind colour. Their smooth, thin skin can be susceptible to damage, so they are best planted in a sheltered area. Meyer lemons are nearly thornless and produce fruit all year, with their main crop in winter.
Regardless of the variety, lemon trees require a position in full sunlight, protected from wind and frost. They can tolerate a range of soils but prefer slightly acidic, well-drained soil. Regular pruning is important to maintain the health of the tree and encourage fruit production.

Soil and water requirements
Lemon trees are adaptable to a variety of soil types, but they do have some specific requirements for optimal growth. Well-drained soil is a must, as lemon trees are susceptible to root rot if the soil is too soggy. In addition, the soil should be slightly acidic and moist.
To prepare the soil before planting, it is recommended to blend in composted manure or quality compost and add a controlled-release fertiliser. If the soil is clay-based, it is important to improve the structure by adding gypsum and forking it in well. This can be determined by digging a hole and pouring a bucket of water into it; if the water takes more than 30 minutes to disappear, the drainage needs to be improved. In areas with poor drainage, it is advisable to plant lemon trees on a raised mound of free-draining soil.
When it comes to watering, lemon trees require regular watering, especially during extended dry periods, to promote good fruit set. However, it is crucial not to overwater them as this can lead to root rot. A good indication of when to water mature trees is to check that the top 5cm of soil is dry. During the warm summer months, it is recommended to water lemon trees every 7 to 10 days, providing them with at least 12cm of water each month.
To enhance the growth of your lemon tree, feeding it with fertiliser is essential. Manual feeding is recommended twice a year, once in February and again in August, using citrus food. It is important to water the soil well before and after fertilising to maximise nutrient absorption. Additionally, natural fertilisers such as coffee grounds and crushed eggshells can boost the tree's growth and fruit production.

Pest control
Lemon trees are common in backyards across Australia, but they are susceptible to pests and diseases. It is important to know what signs to look for and how to treat them.
One of the most common pests affecting lemon trees is the bronze orange bug. These bugs attack fruit, leaving stink marks on the skin and causing the fruit to dry out. They often cluster on trunks during the heat of the day and can be removed by hand or with a jet of water from a hose. Another common pest is the spined citrus bug, which causes similar damage to fruit. Citrus leaf miner is also frequently found on lemon trees in summer, causing puckered growth and leaving silver trails in the leaves. While this pest doesn't affect fruit production, it is unsightly and can be controlled with Success Ultra.
Ants may also be present on lemon trees, often attracted by the presence of scale, aphids, or mealybugs. Controlling these pests will usually get rid of the ants. Sooty mould is another sign of pest attack, indicating the presence of insects such as white fly, which can be treated with an oil-based spray. Mites are a problem during humid summers, causing speckled, discoloured foliage, misshapen fruit, and webbing under leaves. Eco-oil is an effective treatment.
Keep an eye out for signs of pest attack on ripening fruit, including possums, rats, birds, and fruit flies. Pruning your lemon tree regularly will also help with pest control and fruit production. The best time to prune is after harvest and before flowering, and it is recommended to keep the height of the tree under two metres. Removing any deadwood and ensuring the foliage is at least 30cm from the ground will help with pest management and fruit development.

Fertiliser and feeding
Lemon trees are heavy feeders and require regular fertiliser applications to ensure healthy growth and strong fruit production. Citrus trees, in general, are very hungry and will reward you with ample fruit if you provide them with the right nutrients. However, if they are undernourished, they will quickly show signs of distress, such as poor stunted growth or yellowing leaves.
To keep your lemon tree well-nourished, it is recommended to fertilise four times a year: once each in spring, summer, autumn, and winter. You can use a controlled-release fertiliser specifically formulated for citrus or fruit trees. These fertilisers contain the three major nutrients that citrus trees need: nitrogen for leaf growth, phosphorus for root development, and potassium for fruit production. Citrus trees also benefit from additional iron to prevent leaves from turning yellow and dropping off. Natural fertilisers, such as matured compost, blood and bone (which often includes cow manure), and poultry manure, are excellent options for providing these essential nutrients.
When applying fertiliser, follow the package directions, and be sure to water the soil well before and after application. If your tree is mulched, spread the fertiliser underneath the mulch and then replace the mulch to protect the fertiliser from being washed away by heavy rain. A dose of liquid seaweed, such as Seasol, can also be used to condition the soil and promote the uptake of nutrients by the roots.
In addition to fertiliser, lemon trees benefit from being planted in soil that has been amended with composted manure or quality compost. This blend provides a good source of nutrients and organic matter, improving the soil's health and structure. If planting in heavy clay or an area prone to waterlogging, it is recommended to plant on a raised mound or in a raised garden bed to ensure proper drainage.

Pruning
The best time to prune a lemon tree in Australia is during spring or autumn. This is to avoid the extreme elements of summer and winter. For mature lemon trees, the best time to prune is after every harvest, once or twice a year. Baby lemon trees need to be pruned regularly to shape their structural framework. When it comes to more mature lemon trees, they require a lot less attention.
Always remove dead, diseased, or crossing branches. Worn-away bark can be a good indication that branches are crossing and rubbing. Remove any high branches that will bear fruit that will be difficult to pick. Clear out the centre of the tree for air circulation, leading to fewer fungal diseases.
Before pruning, you’ll notice a lot of volume and foliage growing in different directions. After pruning, the fruits should be balanced, and the leaves can receive more air and sunlight. A good rule of thumb is never to chop off more than one-third of the tree. If you prune too much, you could put unnecessary stress on the plant.
It is always important to have the right gear. This includes a trusty pair of pruning shears or a small hand-held saw, depending on the size and age of your tree. Disinfect your tools, and always wear protective gloves when working. For preventive measures, you’ll also need some organic herbicide that you can apply after pruning. All citrus trees are notorious for getting weevils, snails, and gall wasp infestations that can cause problems and ruin your crop.
