Lemon trees are quite easy to stick to, even if you do not live in a warm climate. Create the best environment for them by learning when to bring the potato trees indoors and giving them plenty of water so they don't dry out. When your tree is 2 to 3 years old you should be able to harvest anywhere from 10 to 30 lemons every year!
Edit Create the perfect environment
- Keep your tree outdoors if you live in a warm, temperate climate. As long as your night temperatures do not fall, keep your lemon tree outdoors in a pot. If and when the weather is joking, take the tree indoors to keep it safe. 
- If you live in an area that experiences at least 8 hours of sunlight daily, around and which never falls under, you can plant your lemon tree outdoors in the ground.
- Grow your lemon tree indoors during the colder months. When the temperature begins to fall and frost begins to appear on the ground, bring your lemon tree indoors to a sun room, patio, greenhouse or other room that still allows it to get abundant sunlight through a window. Frost will kill a lemon tree, so pay attention to the weather forecast so that you take it indoors in time. 
- Dwarf lemon tree is a great variety to grow if you I bring your tree indoors. They produce a lot of fruit, but they do not grow so large that it would be impossible to move them. At most they are long, but you can keep them trimmed back to a smaller size if you want.
- Maintain an ideal temperature on. During the summer months it is okay if the trees are in temperatures higher than during the day because they will experience cooler temperatures at night. If the tree is kept inside, keep track of the temperature to ensure that it does not fall too low or rise too high. Especially during the winter months when the air can dry it is important to make sure that the tree does not get too hot. 
- Use a particularly dry climate when using a humidifier when your tree is indoors to keep the climate at the right level, about 50% humidity. If you live in a climate where your tree can grow outdoors, you need not worry about the humidity level.
- Make sure your tree gets at least 6 to 8 hours of sunlight every day. Place your lemon tree in a place where it will have direct sunlight. Avoid putting it anywhere where it will be blocked from the sun by other plants. Depending on the season, move the tree around your yard or patio so that the maximum exposure becomes possible. If your tree is indoors, you may want to move it from season to season to make sure it always has the maximum amount of light. 
- If you live in a climate that experiences very cloudy, dark weather, invest in a gear light. You can buy one online or from your local nursery.
- Keep your tree away from radiators and heat sources. When the lemon tree is inside, make sure it does not lie next to a heat source, as it can dry out leaves and soil. While natural heat and sunlight are good for the tree, too dry heat will damage it. 
- If possible, keep the tree in a room with a ceiling fan or place a standing fan in the room. Circulation air helps keep the tree healthy. Keep the fan on as many hours a day as possible.
Editing Fertilizing and watering the tree
- Choose a well-draining pot that is 25% larger than the lemon tree lamp. The lamp consists of the roots and the clumsy dirt attached to them. If you buy your tree from a nursery, it may already be in a suitable size container – just ask the sales assistant. If you need to replicate it, look for a pot for a 2-3 year old tree or a pot for trees older than it. 
- A pot larger than it will be really difficult to move around.
- Use well-drained, composted soil to cover the tree. Choose sand or loyal soil for an alternative that drains well. Avoid using soil that is made with clay or that has heavy alkaline levels. Cover the bulbous part of the tree (the roots and the dirt attached to the roots), but stop when you get to the bottom of the roots. 
- Lemon trees are beautiful hardening and can grow in many different types of soil, although the lush soil is the preferred type. If you want to test the pH level, try to read between 5.5 and 6.5 for optimal growth.
- If the soil is too acidic, you can add a base such as compost or manure to the soil.
- If the soil is not acidic enough, add a compound of powdered limestone.
- Fertilize only the soil surface so that you do not disturb the roots of the tree. The fertilized tree was 1 to 2 months in the spring and summer and every 2 to 3 months in the autumn and winter. Use a citrus-specific fertilizer and apply it only to the top of the soil. Do not mix it with the rest of the earth. 
- Spring and summer are the active growing months; autumn and winter are dormant months.
- Water your lemon tree was 10-14 days. Water the tree while slowly counting to 20. Stop when you notice that water starts to come out of the pot, If after 20 seconds you still do not see water from the pot, continue counting and watering for another 10 seconds. If your climate is particularly dry, keep track of the soil and the tree leaves. If the soil is dry on the touch or if the leaves are hanging, the tree watering. During the hottest months, you may need to water it once or twice a week. 
- Keep your tree in a place where it will not sit in water. While lemon trees need a lot of water, they should not be left to sit in water. If the pot is out, place it somewhere that rainwater will float away from it rather than to it, as on a garden wall or at the highest point of a slope. 
- If your area is experiencing really big rain, you might want to bring your lemon tree indoors or place it under an awning until the rain passes.
Edit Harvest and pruning
- Choose lemons when they are firm and in size. Choose very green lemons if you prefer a more sour fruit. The yellow it gets, the sweeter it gets. Lemons continue to mature even after they have been picked from the tree. 
- The lemons can still be green when they reach the right size, and that is okay. The size is actually more important than the hue of the fruit.
- An acidic lemon has long been left on the branch.
- Twist the fruit gently until it breaks off the branch. Grasp the lemon in one hand and turn it around the branch. It should snap quite easily. If you prefer, you can also use a clean pair of garden shears to cut the lemon from the tree. 
- Avoid pulling the lemon, as it can damage the branch or even loosen it completely from the tree.
- Crop your lemon tree from March to May so it will be healthy. The best time to prune your tree is after most lemons have been harvested, but before the new buds begin to flourish. Depending on your climate, crop sometime between late winter and early spring. 
- Pruning is important for keeping the tree healthy and promoting new growth.
- Use clean scissors to trim each new shoot down to half its original length. Cut the branch at a 45 degree angle and never cut back all the way to the main stem. Focus on pruning the longest and rocking of the branches and leaving the thicker, more established branches alone. Trim back all low-hanging, downward-facing branches that extend toward the ground. 
- Also, take time to remove dead leaves from the branches and remove the fallen from the land when you notice them.
- Keep an eye on pests to treat any problems that arise. Keeping your lemon tree cropped is an excellent first step to prevent unwanted pests from making their home in your tree. If you notice spider mites or aphids, use a hose to knock them off the tree (do this outdoors). If problems persist or there are other pests on the plant, you can use an insect repellent or garden oil to protect your tree. Be sure to ask a professional and follow the instructions so that you do not damage your lemon tree. Some of the most common pests are: 
- Red mites: small red insects that eat leaves and twigs on citrus plants
- Spidermids: small white insects that are more common in colder climates
- Citrus milk fish: Small, flat, oval and wingless, these creatures are covered with a waxy substance that looks puffy
- Citrus wild flies: small white wings insects appearing on the underside of citrus leaves
- Start with an already established lemon tree, which you can buy from a nursery. Growing a lemon tree from a seed can take up to 2 to 3 years to start producing fruit, making it a long-term investment.
