Lemon tree care outdoor required choosing the right place, and watering properly. Pruning, fertilizing, pests, and diseases control and harvesting. 


When you plant a lemon in your garden choose the right place where the full-day sunlight reaches the lemon. Full-day sunlight increases the process of photosynthesis. Without proper sunlight, the tree cannot bloom and grow properly. So choosing the right place is very important 


Lemon tree care outdoor requires to understand watering needs. Only water the lemon tree when the soil is completely dry. Soil should have moisture all the time. When your tree starts flowering overwatering and less watering also can cause the flowers to drop. You can easily check the moisture of the soil by inserting a finger 2 to 3 inches into the soil you can feel the moisture or dryness.


Pruning is main factor in lemon tree care outdoor or indoor. When your tree reaches the age of about 11 to 12 months you can start pruning. It is important to keep your tree in shape. Before the start of the spring season, you can prune your lemon tree. Cut the branches which cross each other. Cut the branches that grow below the grafted area these branches are called suckers. Remove the dead branches. Sunlight and air can pass through the tree easily. Do not over prune it can kill the tree. You should prune once a year. Use sharp shears to prune and disinfect the shears with alcohol pads before using.

Note: Pruning increases fruiting


Understanding how and when to fertilize is important for lemon tree care . The lemon tree needs both macronutrients and micronutrients for its good growth and fruiting. Fertilizing lemon trees boast the fruiting and fulfill the nutritional requirements of a tree. Nitrogen phosphorous and potassium are the three vital nutrients required by any plant

Nitrogen is required for leaves and new growth

Phosphorus is required for roots growth

Potassium is required for flowering and fruiting   

You can use a balanced diet of 20-20-20 NPK for lemon trees. When your tree starts flowering then decrease the nitrogen and increase the potassium. You can use 5-15-45 NPK. You can spray and use it in roots also.


Controlling pest and diseases is also one of the main factors in lemon tree care outdoor. Some serious pests and diseases do not attack lemon trees easily. Some common pests can attack your tree but they can easily be controlled by using organic pesticides neem oil or for the instant result you can use pesticides of any well-reputed brand. If you are a beginner I would suggest you use chemical pesticides because neem oil or any other organic pesticide takes time and a beginner can be disappointed. Read instructions properly before using any pesticide.

Common pests and diseases:


Aphids attack at the start of the spring season. Aphid sucks sap from newly growing leaves and weakens the plant. It is a tiny insect that spreads very quickly. Aphids can be spotted under the leaves. You can check the undersides of leaves and if aphids are there spray pesticide timely so it does not spread more.

Leaf miner

The leaf miner eats the plant tissue. It is a tiny insect. When leaf miner eats plant tissue it can weaken the plant because the process of photosynthesis is affected. You can use neem oil to get rid of the leaf miner.


If you see some white cotton like something on leaves, stems, and fruit also it is called mealybugs. There are many ways by which you can rid of mealybugs. It can drop the fruiting. 

Spraying neem oil is very effective for mealybugs.  

Spraying soap water is also very effective.

You can use chemical pesticides which can give you instant results. 

White fly

Whitefly which is also known as citrus whiteflies can attack lemon tree. Whiteflies attack the leaves of the tree. It feeds on the sap of the leaves. You can easily control the whiteflies by using soap and water liquid. You can add a few drops of shampoo/ liquid hand wash in 1 liter of water (take the amount of water according to your tree size). For the best result, you can mix a few drops of neem oil. Whitefly are spotted under the leaves while spraying keep in mind that spray reaches the underside of leaves. 


When the lemons or any citrus fruit is ready to harvest I would suggest you always harvest using the sharp pruning shear or any cutter than hand picking. Harvesting with the shear method increases the fruiting from where you will cut the branch/shoot to harvest the fruit from there two more new branches will start to grow. Harvesting with hand picking method can decrease fruiting.
