How Often To Fertilize Lemon Tree In Pot

When it comes to fertilizing a lemon tree in a pot, there is no one-size-fits-all solution. The frequency with which you need to fertilize the tree largely depends on the size of the pot, the quality of the soil, and the tree’s age. Generally, mineral-rich compost should be applied around the base of the lemon tree every four to six weeks in the growing season, being sure to avoid over-fertilizing. The potting mix should also be tested annually to ascertain specifically what nutrients it is lacking and to determine whether additional fertilizer should be added.

In addition to applying fertilizer every four-to-six weeks, your lemon tree will benefit from a quality potting mix and regular watering. Citrus trees require air deep within the soil to allow their roots to take in oxygen, so a more porous potting mix is recommended. Young trees should be watered at least twice a week, while more established trees should be watered a couple of times a month (but more in hot and dry weather). Be sure not to overwater.

Lastly, lemon trees require a slightly more acidic soil to flourish. Keep the soil pH between 5.5 and 7.0, although 6.5 is optimal. To ensure the pH level doesn’t become too high or too low, the soil should be tested every few months. If you find the pH level has altered from its optimal level, agricultural-grade sulfur or a carefully selected soil conditioner should be added to adjust it.

Watering requirements

When it comes to watering your lemon tree, there is no definite answer as to how often you should do so. Factors such as temperature, climate and the size of the pot all need to be taken into account. Generally, it is recommended to water your tree twice a week in the summer and once a week in the winter. It is also important to aim the water slightly under the leaves in order to keep the foliage free of dust, which can prevent your tree from receiving adequate sunlight.

In hot climates, your tree may need watered more often. To know for sure, check the soil’s moisture using your index finger first. If the soil is dry below the surface it needs watering, otherwise it is likely still saturated. It is important to remember that overwatering can be just as damaging as underwatering. Too much water can cause root rot, as it causes the roots to become stagnant, preventing them from accessing oxygen.

By understanding your tree’s specific water requirements, you can ensure its health and longevity.


Citrus trees need plenty of sunlight in order to thrive, so it is important to select a spot in which they can get up to eight hours of sun each day. When placed in the right conditions, a lemon tree should bloom profusely and produce more fruit than if it were planted in the ground.

One issue with having a lemon tree in a pot is that the roots of the tree become more easily exposed than in the ground. When planted in a pot with no shade, the tree’s roots can become very hot in the afternoon or afternoon sun and start to overheat, resulting in the tree becoming stressed. If you are growing a lemon tree in a pot, be sure to provide it with some shade during the hottest periods of the day.

Another crucial environment factor is air circulation. Citrus trees require air to be able to draw oxygen and other nutrients from the soil to their roots. A lack of air circulation can create an overly humid soil environment, which can cause the roots to rot. Be sure to place your tree in an area with a good level of air circulation, such as an open sheltered spot away from walls or other structures.

Fertilizer Requirements

The amount and type of fertilizer you should use on your lemon tree will depend on the soil and characteristics of the tree. Generally, it is recommended to use a citrus-specific fertilizer four to six times a year, applying it to the base of the tree. Additionally, use a nitrogen-rich fertilizer in order to help with growth and fruiting.

It is important to note that over-fertilizing can result in excessive foliage growth at the expense of flowers and fruit. Avoid using a fertilizer with too high a nitrogen content as this can also lead to vigorous foliage growth. To ensure you are not over-fertilizing, check the soil using a quality fertilizer tester.

Pest prevention

Pests, such as aphids and mealybugs, can cause a lot of damage to a lemon tree in a pot, so it is important to take steps to prevent them from taking hold. At the first sign of pests, treat the tree with an organic citrus-friendly insecticide according to the instructions on the packaging. As a preventative measure, reduce the insect population nearby by refusing to use chemical insecticides and allowing natural predators, such as ladybugs and birds, to spread.

If you find the population of pests increasing, then contact a professional pest control specialist, who can help identify the problem and provide the right treatment. Additionally, it is important to regularly inspect your lemon tree for any signs of damage or signs of stress.

Pruning Requirements

You can easily control the size and shape of a lemon tree in a pot by pruning it regularly. Pruning helps control the growth of a lemon tree, prevents it from becoming top-heavy, and keeps it from taking up too much space. When pruning, be sure to focus on thinning out the branches and removing any dead or damaged wood, as this will help to promote new healthy growth.

When dealing with a mature tree, it is important not to prune away all its leaves as this can lead to a lack of foliage and an inability to produce fruit. Additionally, a mature lemon tree should be pruned only when necessary as it can cause a lot of stress to the tree.


In summary, when taking care of a lemon tree in a pot, there are several factors to consider to ensure its health and longevity. It is important to understand the particular soil and environment requirements of the tree in order to fertilize and water it correctly. Additionally, pest prevention and pruning are activities which should not be overlooked.
