How Much and How Often to Water Lemon Trees?

Although lemon trees increase and thrive in tropical climates that acquire immediate light-weight, they have also grow to be common fruit trees in colder climates. For lemon growers in tropical climates, making a watering routine is a non-concern. Even so, for gardeners in colder climates, watering can be tricky since lemon trees are extremely delicate, especially when nevertheless younger.

This report will explore how a lot and how usually you need to h2o your lemon trees depending on no matter whether they are developed indoors or outdoors, what the season is, and the irrigation method. Hold reading through to learn more.

How Much to Water Lemon Trees

According to research by the University of Arizona¹, experienced lemon trees can use about sixty inches of drinking water for each calendar year. This will, of training course, rely on the dimension of the tree and corresponds to 135 gallons of h2o in summer time and about 17 gallons in winter. Even though this data is perhaps beneficial to huge-scale business lemon farmers, it is irrelevant for a house gardener with a constrained number of lemon trees.

If expanding one particular crop kind, the soil will not properly recycle water and nutrition. Additionally, most of the topsoil and drinking water are dropped, and as these kinds of, a great deal of water is necessary for payment. The information from the college also exceeds the typical rainfall obtained in tropical climates in which lemon trees are native and can develop with small human intervention.

So, how a lot should a person from a colder weather drinking water their lemon trees?

Well, citrus trees will want h2o at minimum twice a 7 days. The amount of drinking water provided will depend on variables such as year, spot, tree dimensions, soil kind, and age.

If your citrus plant is even now young, it will need watering about 2–3 moments in the initial 7 days and as soon as each week for the subsequent two months. In addition, recently planted lemon trees will require about 5 centimeters of drinking water for them to get recognized.

For experienced lemon trees, you will need to have approximately a hundred and fifty centimeters of h2o every single calendar year. If the tree has designed a 14-foot canopy, for occasion, it will want about 110 liters of water in every single watering session. Nonetheless, if ambient temperatures rise earlier mentioned 32℃, you could have to boost the watering frequency to as soon as for every 7 days to guarantee the soil continues to be moist.

How Often to Water Lemon Trees

For a lemon tree to prosper, you should only h2o the plant when the topsoil layer (about 2–4 inches) receives dry. If lemon trees get overwatered, they turn out to be susceptible to root rot, and if underwatered, they could fail to bloom and create fruits. As a result, it is crucial to get the watering appropriate.

Sadly, there is no basic rule for watering citrus trees. As described previously, the frequency of watering lemon trees will also count on a number of aspects. These incorporate the irrigation technique employed, the period, soil type, and regardless of whether the plants are grown indoors or outside.

Under is the watering timetable dependent on some of the most crucial variables that gardeners need to take into account.

Based on Irrigation System and Schedule

  • Hose: Hoses are the cheapest and least time-consuming method of watering lemon trees. Unfortunately, this method presents a high rate of operator errors due to impatience, neglect, and inexperience.
  • Drip Systems: Drip systems are a popular choice for most gardeners because they are easy to install. However, they are not scheduled to run long enough to fully saturate the soil resulting in wilting and drying of the plant leaves. So, a drip system should be run for at least 2 hours once or twice a week to ensure that the soil is sufficiently saturated with water.
  • Sprinklers: This irrigation method may be more expensive than the two methods above, but it distributes more water to the plant in less time. For a fully mature tree (15 gallons), you should run your sprinklers for 15–25 minutes, depending on the soil type.
  • Bubblers: Bubblers are similar to sprinklers in water distribution. However, they distribute water faster and direct it to a localized area. You may need additional bubblers as the tree roots grow and spread but they can effectively saturate a drip zone in just 5 minutes.

Based on Season


For the duration of the very hot and humid summer season months, humidity desire in lemon trees substantially will increase. At this time, the trees are likely to be actively increasing and building fruits. So, your watering routine will be far more frequent. Positive, lemon trees are drought resistant and can very last for far more than a week with out drinking water in summer time, but they will require a generous soak and need to have to be planted in soil produced up of lots of organic and natural issue for dampness retention.

Any lemon tree much less than 6 ft will need about five gallons of drinking water each week throughout summer. The more substantial and much more mature trees will want far more water and as this kind of, you might want to seek advice from a expert citrus care chart for far more actual measurements.

You may have to average the amount you give your plant primarily based on the weather conditions since if your area gets sporadic rainfall, watering your tree may lead to root rot. In addition, you will have to alter your routine if your tree is growing on quick or slow draining soils or growing somewhere particularly vulnerable to high winds that might suck moisture from the plant leaves.

Both way, so extended as the best two inches of soil are dry and crumby to the touch ahead of watering, you can stay away from a complete host of issues linked with underwatering and overwatering your lemon tree.


A single of the greatest problems most lemon tree growers experience throughout wintertime is overwatering. For the duration of these cold months, the plants slip into a dormant condition and call for significantly significantly less water. For that reason, drinking water is only required to guarantee the plant remains moist during wintertime. The watering timetable will rely on no matter whether the vegetation are expanding indoors in a pot or developing outside the house on the floor.

If exterior, they can achieve their watering necessity from the atmosphere, but if indoors, you will have to drinking water the plant oneself. Just view out for early signs of underwatering such as leaves curling and dropping off, and alter your h2o frequency accordingly. Nevertheless, remember not to spray drinking water on lemon tree leaves to avoid fungal and mould growth in the course of these chilly months.

Based on Growing Indoors vs Outdoors

Lemon trees increasing indoors or outdoor¹ have certain differences in their requirements and care solutions for them to thrive. Individuals developed outside have a tendency to be susceptible to environmental situations compared to the indoor variant. This is because the gardener has minor or no management more than the lemon’s surrounding surroundings. Therefore, drinking water the vegetation when each and every two months.

On the other hand, indoor-grown lemon should be watered at minimum when a week or right away when the soil humidity articles signifies that the plant needs watering. Another critical facet in conditions of watering indoor lemon trees is the potting dimension¹.

Excessively big pots are not suggested due to the fact they are susceptible to overwatering, specially if you have recently transferred the plant. As a rule of thumb, a two-to-3-12 months-old lemon tree will call for a 10”–12” diameter pot, although a larger plant will thrive in a ½ gallon barrel.

How to Tell Your Lemon Tree Needs Water

Aside from checking the best 2 inches of soil for dampness material, if your lemon leaves are turning yellow, curling up, drying, and falling off¹, odds are high that it’s not receiving adequate water.

The small measurement of the fruits made is also a confident indication of underwatering. This is because citrus trees are an evergreen plant species, and, as this kind of, need to not be getting rid of leaves throughout fall and winter season like the deciduous plant species. In fact, they shouldn’t lose any leaves throughout the calendar year.

Thankfully, with suitable care and routine maintenance, the plant ought to be in a position to get well its leaves back again. 1 way of stopping wilting in your citrus plants is by adding mulch or compost to protect the plant from the aspects and increase its dampness retention capacity.


As you may have collected, lemon trees are indigenous to tropical climates, and as this kind of, they want adequate rain, direct solar, and coarse draining soil to thrive. So, if your lemon is wilting and dying, it is possibly lacking in one of the three important places. When it will come to watering lemon trees, your goal should be to keep the soil moist, but not oversaturated. Even so, this is a balancing act and will rely on a number of factors.

If increasing indoors, the plants will require considerably less h2o a less frequency (at least as soon as a 7 days). Throughout winter, the plants will need at least watering when each two weeks because they are typically dormant. But if growing indoors, drinking water it at least when a 7 days.

To uncover out if your lemon tree is getting the right quantity of drinking water, examine out for curling and dying leaves, which suggests underwatering, or rot in roots which reveal overwatering. The good news is, you can lessen the volume supplied to your tree by mulching, drip irrigation, shading, and utilizing far better draining soil. This will make the plant self-sufficient and ready to thrive wherever no subject the climate.
