You’ve spent weeks taking care of the lemon seed and then months while it was growing to become a lush lemon tree and now you’re afraid it may die if you don’t take care of it in the right way?

Luckily for you, in this guide, you can read and learn how to look after a lemon tree indoors.

No one wants a dead lemon tree and taking care of it indoors can be challenging, especially if you live in the area that’s not suited for lemon. That’s why you’ll find this guide very useful.

Keep The Soil Moist


It’s very important to make sure that your lemon tree is getting the right amount of water. Since lemon thrives when watered regularly, the soil should never be dry because the lemon will suffer. It needs water to absorb all the nutrients for optimal growth.

You should water it every week, but you should take care of it and follow the level of moist in the soil in the meanwhile. If it seems too dry, feel free to water it even more often.

Just keep in mind not to exaggerate since lemon doesn’t like being over-watered, so avoid paddles inside the pot and keep the soil damp but not overly wet. You can control the level of moisture with a moisture sensor that are very accurate.

If you’re uncertain how to know if the lemon tree is getting too little water, keep an eye on the leaves. If they start curling, this means that the plant needs more watering.


Mind The pH Level Of Both Soil And Water


Since you used the slightly acidic soil mixture when planting your lemon tree, it’s important to keep it that way even when the tree’s grown. If the pH level changes, that can influence the tree and make it suffer.

It would be ideal if you had a pH meter and controlled your soil every once in a while because that can really help a lot if you’re wondering how to look after a lemon tree indoors. A certain pH level helps the plant absorb all the necessary nutrients, and that’s why it’s so important.

Also, watering the tree with tap water isn’t the best idea because that water has a neutral pH level which means that the number on the pH meter will be between 7 and 7.5, and since lemon prefers slightly acidic pH level, the number should be below 7 (around 5-6).

You don’t have to worry about that because you can easily use the tap water and adjust its pH level with some simple hacks.

Since you need to make it more acidic, the best way to do that is to mix a tablespoon of white vinegar with four liters of water, and that will do the trick. If you’re uncertain, you can always measure the pH level of the water before pouring it into the pot.

The Air Needs to Circulate


The lemon tree adores the warm air and slow warm wind. That’s why you should keep the window next to the plant open in order to let the air in. If the weather is too cold for the lemon, you can use a fan and leave it on next to the plant.

Keep Your Lemon Tree Next to a Sunny Window


Since the lemon tree is a plant that loves being on the sun, you should make sure that, even when the tree’s grown, it remains close to the source of sunlight. The lemon can be exposed to the sunlight up to 12 hours, but the minimum should be at least 8 hours if you want it to grow its best.

Not only will the light be beneficial to the growth, but it is also important to expose the tree to the warmth. That’s why there has to be a lot of sun, or at least growing lights if the area you live in doesn’t have a lot of sunny days.

Use Fertilizers


The lemon tree needs nitrogen to grow well. Purchase a fertilizer that contains nitrogen and then sprinkle the soil with it every three weeks during warm months and every six weeks during cold months.

This is an important step when learning how to look after a lemon tree indoors. The fertilizers will feed the plant and give it the nutrients it needs to grow good lemons. Avoid those that contain alfalfa meal because that can cause fungus.

Keep A Humidifier Close


How To Look After a Lemon Tree Indoors

You will need to mimic the exact outdoor conditions for as long as you want your lemon tree to thrive. When I first tried to grow and take care of my lemon tree, I completely ignored the fact that the lemon tree needs humidity in order to grow better.

That’s why my first attempt wasn’t successful, and I can tell you now that you should invest in a humidifier and keep it next to your plant. This is extremely important if you, just like me, live in an area that doesn’t have humid air.

A good thing you can also do is to mist the tree a couple of times a week because this can help with the level of humidity.

Maintain The Optimal Temperature


The lemon tree doesn’t like cold. If the temperature inside the room is below 12.8 degrees Celsius, the tree will stop growing, and there won’t be any fruit.

If you want a lush lemon tree, make sure that the temperature during the day is around 21 degrees Celsius while during the night it should be around 12.8 degrees Celsius.

Pruning


If you notice dry and dead leaves and broken branches on your lemon tree, you should remove them carefully. However, you shouldn’t do it too often and don’t exaggerate while doing it. Once-twice a year will be more than enough.

You need to remove the dead leaves and branches because they can consume the energy that could be used for growth, and that will make the tree grow slower.

Adjust The Pot Size To The Size Of The Lemon Tree


As your lemon tree grows, you should replant it in bigger pots. The roots of the plant need space to grow well and consume nutrients, and that’s why a pot that’s too small can be a disaster for the lemon tree.

So, don’t forget to always purchase a bigger planter as soon as your tree is too large for the old one. This is also important for the balance of the tree inside the container, especially when it’s full of lemons – the bigger the pot, the better the balance.

Remove The Extra Lemons


If you notice that your tree has given too many lemons, the best solution would be to remove the majority of them in order to allow the rest of them to grow. While your tree will probably drop lemons naturally if you notice that that’s not the case after a few months, remove them with pruning shears.

If you don’t do it, those lemons will consume all the energy of the tree and therefore stop the rest of the lemons to consume it as well.

Related Questions


1. The leaves on my lemon tree are becoming yellow; what do I do?

The first thing you should consider and think about is – are you watering your tree regularly? If you do and the leaves are still yellowing, then your plant probably needs some nutrients. This is the best time to use fertilizers on your tree.

2. Do I need to use a stick as support while lemon tree’s growing?

With lemon trees, this is not necessary. However, it won’t hurt it so you can use a stick if you want to. The branches on the lemon trees can be heavy, especially when the lemons are grown, even though this plant doesn’t need additional support, this can be your decision.

3. Will my lemon tree die if the temperature is too low?

While lemon trees need warm the temperature around 21 degrees Celsius to grow their best, even if you keep your tree in a room where the temperature is lower than 12.8 degrees, the tree won’t die. It will only stop growing and giving lemons, and therefore, it won’t be useful.

Final Word


As you can see, your care about a lemon tree doesn’t end once they start growing lemons. You need to learn how to look after a lemon tree indoors and make sure you’re doing everything right and mimicking the natural conditions in the best way possible if you want your tree to continue growing.

Following the tips from this post will be very helpful and your lemon tree will thrive for as long as you take care of it and keep it in the room that has the right temperature, humidity, and air flow.
