How to Grow and Care for an Indoor Lemon Tree
With sweet-smelling flowers, glossy foliage and tart, tasty fruit, an indoor lemon tree rewards your attention year-round. Regardless of your climate, you can grow a container lemon tree indoors and enjoy your own homegrown lemons. Growing indoor lemons isn't hard as long as you choose the right tree and meet its special needs. These basics on how to grow and care for an indoor lemon tree can have you drinking lemonade in no time.

When grown outdoors in warm climates, regular lemon trees grow 20 feet tall and take up to six years to bear fruit.1 For indoor lemons, you need a tree that stays small and delivers lemons sooner. Growers graft indoor lemon tree varieties onto special dwarfing roots that speed up fruit-bearing ability and keep trees small.
Some of the easiest, most popular indoor lemon trees are actually crosses with other fruits, but some are true lemon trees that do well in pots. The best dwarf indoor lemon tree varieties include:
- Dwarf Improved Meyer – The easiest indoor lemon tree, this cross between lemon and mandarin orange offers sweet, tangy lemons.
- Dwarf Ponderosa – Another popular indoor choice, this lemon and citron cross bears large lemony fruit.
- Dwarf Variegated Pink Lemonade – The green-and-yellow variegated fruit on this true lemon tree has pink flesh (but clear juice).
Most dwarf lemon trees sold by nurseries are two to three years old — old enough to start bearing fruit, but still immature. Container size helps limit a tree's eventual height, but most indoor dwarf Meyer lemon trees grow to at least 3 to 4 feet tall. Other indoor varieties can grow to 6 feet or more.
If you plan to grow a lemon tree from a seed, understand that the new tree won't be the same as the one the seed came from. Starting a lemon tree from a cutting will yield the same tree — from the ground up — but the process is challenging. Either way, your new tree won't have the small size and disease resistance of grafted dwarf trees, and you won't see fruit for many years.
Lemon trees fill your home with fragrance and fruit.
It's tempting to start your lemon tree in a pot worthy of its final size, but it's better to start out small. Overly large pots with excess soil make it difficult to tell when your indoor lemon tree needs water. For most young, nursery-grown trees, start with a 12-inch diameter container. As your tree grows over the years, slowly progress to pots double that size in width and depth.
Lemon trees do well in all kinds of pots, from porous terra cotta to lightweight resin. Just make sure the container has large, unobstructed drainage holes. Like other citrus trees, lemons prefer cool roots, so avoid black pots and other dark colors that heat up in sunlight.
Always use a deep saucer under your container to protect indoor floors from excess water. Consider putting a wheeled plant dolly underneath. Lemon trees get heavy and hard to move as they grow.
Lemon tree roots demand abundant oxygen, so proper planting and excellent drainage are key. When planting your tree, the flare at the base of the trunk should sit slightly above your eventual soil line.
Start by filling the new container's bottom with soil, then lightly tamp it down. Repeat until you reach the right depth for your tree's root ball. This helps provide a good foundation so your tree won't settle in too deeply. Always leave a few inches at the top for watering.
Indoor lemon trees do best when their soil stays evenly moist. Choose a well-draining potting mix designed for indoor palm trees or citrus. These mixes help prevent soggy soil while still retaining moisture, so roots don't get too wet or too dry.
As a final step, treat your newly planted lemon tree to Pennington UltraGreen Plant Starter with Vitamin B1, which provides micronutrients and reduces transplant shock.
Nursery-grown dwarf lemons bear fruit at a young age.
Once your lemon tree is in its new container, it's ready for its new environment. These two factors are critical to a successful indoor lemon tree:
- Light: For peak performance — from blooms to fruit — your indoor lemon tree needs close to eight hours of sunlight each day. The more light it gets, the better your results will be. Lemons generally do well in front of unobstructed south- or southwest-facing windows. You can also add artificial light if needed.
- Temperature: Indoor lemon trees grow best with nightly temperatures near 65 degrees Fahrenheit, which suits most homes fine.
Lemon trees won't tolerate hot or cold drafts, so place them away from all air conditioning and heating ducts.
During warm summer months, consider giving your indoor lemon tree an outdoor vacation. Once all danger of spring frost passes, gradually acclimate it to the outdoors. The extra sunlight will do it good — and reward you with fruit. Before fall frost comes, move it back inside. Always move lemon trees gradually. Abrupt changes in light and temperature can make fruit drop.
To keep your lemon tree healthy, allow the soil to dry out about 3 inches deep before you water. Then water thoroughly until it runs through the pot's drainage holes. Keep the soil moist, not overly wet, but never let it dry out completely. Test soil with a moisture meter (available online and in garden centers) or use your index finger instead.
During active growth, especially if they're outdoors during summer, container lemon trees may need daily watering. During winter, water only as needed to keep soil moist. Timing varies depending on your indoor temperatures, your container and your tree size. Watch for warning signs such as yellow leaves, which signal soggy roots or nutrient problems.
To grow tasty fruit and beautiful foliage, your indoor lemon tree needs proper food. Like other citrus trees, lemon trees require plentiful nitrogen as well as other essential nutrients, including magnesium and iron.1 This is especially important for indoor lemon trees, which are restricted to containers.
A premium citrus fertilizer such as Pennington UltraGreen Citrus and Avocado Plant Food 10-5-5 provides indoor lemon trees with an ideal blend of primary nutrients and micronutrients at planting time, then it keeps feeding for up to four months.
As your tree grows older its needs will change, so follow label instructions for your indoor lemon tree's age and pot size. Feed container lemon trees every three to four months. Avoid disturbing shallow roots when you feed.
Indoor lemon trees look as good as their fruit tastes.
Unlike some fruit trees, lemons are self-pollinating. That means they don't need pollen from another lemon tree in order to bear fruit. But in nature, lemon trees rely on insects to pollinate their blossoms. Better pollination translates to more and better fruit.
With popular indoor varieties your tree should bear fruit on its own, but you can also help it along. When flowers are blooming and you stop to inhale the intoxicating fragrance, gently shake the branches to help spread pollen within the blossoms.
Indoor lemon trees typically need little to no pruning. Most indoor varieties are thornless, but some lemon trees have thorns. Wear long sleeves and gloves to prune away thorns and all shoots or roots near soil level. Most lemon trees fruit on outer branches, so wait until after fruit sets to avoid pruning away your prize.
By learning how to grow and care for a lemon tree indoors, you can enjoy a year-round parade of beautiful foliage, fragrant blossoms and shareable lemony treats. At Pennington, we're committed to bringing you premium plant fertilizers and expert advice to help you grow the indoor lemon tree of your dreams.

Nothing embodies the warm, carefree vibe of spring and summer quite like citrus fruit. And lemon trees are arguably one of the best to choose for your own at-home orchard. Why? Well, for starters, they're super easy to grow and generally fruit quickly, even in less-than-stellar and cooler climates.
Plus, having a lemon tree is like having a little slice of the tropics right in your backyard. There's nothing like their fresh flavor and versatility.
Choosing Your Tree
Though it's a symbol of exotic, island-inspired growth, there are many places you can grow a lemon tree. Even if you live in an area where it gets cold outside, you can plant your lemon tree in a pot and bring it indoors during the winter. But if you're not sure what to choose, we've highlighted a few of our favorites below to get you started on your citrus journey!
1. Meyer Lemon
The famous favorite. The Meyer Lemon Tree is probably what comes to mind when you think of versatile indoor or outdoor growth and amazing, easy-to-grow flavor. It's especially known for offering both sweet and savory flavors from each squeeze, making it even better than store-bought.
In fact, Meyer Lemons aren't available in grocery stores because its thin skin is subject to easy bruising. However, this delicious skin also allows the citrus juices to develop fully, making it the perfect raw fruit for juices, desserts and flavoring.
While some lemon varieties can grow as tall as 20 feet, a Meyer Lemon tree will naturally reach between 10 and 15 feet tall.
2. Eureka Lemon
The top choice for growing juicy lemons on your patio is the Eureka Lemon Tree. Dwarf-sized for easy harvests, the Eureka Lemon offers effortless home-grown fruit and the benefit of drought tolerance.
It's no wonder the Eureka Lemon Tree is the most popular selection amongst homeowners who grow their own citrus fruit. You'll easily grow bushels of lemons that are great for lemonade or for adding a sweet flavor to your meals.
The Eureka is also adaptable to most soils and conditions, and you don't need to spray harsh chemicals because it isn't prone to pests or diseases.
3. Limequat Citrus
The Limequat Citrus Tree is technically not a lemon tree, but as a member of the citrus family, it's a must-have.
The Limequat is exactly how it sounds: a natural cross between a Key Lime Tree and a Kumquat Tree. This variety offers small, yellow-green, oblong fruit about the size of kumquats, which are perfect for snacking without peeling.
Limequats have the sweet flavor of limes and oranges with a tart aftertaste. Their unique flavor is perfect for cooking with, as well as adding to drinks, to give your favorite recipes some extra zest.
How to Plant Lemon Trees IndoorsLemon Trees are a great low-maintenance plant and can grow perfectly even within your house!
As a citrus variety, lemon trees require full sun, which means about 6 to 8 hours of direct sunlight daily. For indoor growth, simply place them in front of a south-facing or sunny window.
Once you've scouted your chosen area and selected your favorite lemon tree, it's easy to plant. Select a container that's about one and a half or two times the width of your tree's shipped container. When selecting a container, make sure there are adequate drainage holes as any citrus will be unhappy with overly wet roots.
How to Plant Lemon Trees Outdoors
To plant outdoors, place your lemon tree in a south-facing area that gets plenty of sun and drains well. If you soil is clay or poor drainaing try mixing in some organic matter or compost to boost fertility and drainage of the area. Other than that, lemon trees just need a regular watering schedule and a plan for fertilizing.
The best time to plant your lemon tree is during the spring, to avoid any harsh winter or summer temperatures. This also depends on what growing zone you're located in so check and make sure that the ground isnt frozen and you are past the risk of frost.
Dig your hole just as deep and approximately twice as wide as the tree's root ball. After you've got everything ready, place your tree and loosen its roots just a bit. Then, backfill your hole with soil and 2 inches of compost and water well.
When the planting process is complete, you can also spread a 2 to 3 inch layer of mulch over the tree's root area to preserve moisture. Just ensure you keep the mulch away from the tree's bark.
Lemon Tree Care
So, how should you care for your lemon? Caring for your lemon tree can be broken down into these five steps: watering, fertilizing, pruning, pest & disease solutions and harvesting.
1. Watering
Generally, a lemon tree should be watered once weekly or bi-weekly, depending on rainfall in your area or your humidity indoors. A watering schedule is important to keeping your lemon trees healthy and happy. But if you're not sure when to water your lemon trees, just check the top 2 inches of soil. When this area is dry, it's time to water.
FGT Tip: Citrus leaves love humidity. Indoor lemon trees will do best if misted daily, especially when you're running your heat during cooler months. You can also use a humidifier or fill your pot's saucer with rocks and add water; place your plant on the rocks, ensuring the bottom of the pot is above the water line, for best results.
2.

We recommend fertilizing your lemon trees (especially Meyers) every four to six weeks, from February to August, to ensure a healthy cycle. Citrus trees benefit from fertilizers that are generally balanced with a slightly nitrogen-rich blend.
3. Pruning Your Lemon Tree
Prune as needed to maintain your lemon trees' shape. Clip any branches that are too long, and remove branches growing toward the trunk of the tree instead of away from it. This process maintains airflow between the branches and allows light to penetrate the center of the tree.
FGT Tip: Sterilize your pruning tools with rubbing alcohol. This ensures a clean cut to keep your lemon trees healthy.
4. Pest and Disease Solutions
Citrus canker, root rot and mites are the most common pests and diseases affecting lemon trees, but luckily, they're easy to treat, especially with organic, natural solutions. And if you keep your lemon trees indoors, you simply need to monitor and clean the leaves.
If you're treating, ensure that you always use an approved fungicide, or just remove any dead or diseased areas. Fully remove infected material from the tree. Don’t use any of this material for compost.
5. Harvesting
Now it's time for the best part: harvesting! Lemons are ready to pick when they're yellow or yellow-green on the outside. And most of our lemon trees are primed for harvest after only a couple of years, or sooner.
How Long Does it Take a Lemon Tree to Bear Fruit?Lemons ripen anywhere between 4 and 12 months after flowering, with blooms appearing in spring to signal a later transition to fresh fruit in the summer. The exact time it takes for the fruit to develop will depend on the specific variety and growing conditions, but many of our lemon varieties will typically fruit within the first 1-2 years.
So, no matter the variety you choose, ease and home-grown flavor await - select your favorite from our delicious and juicy lemon trees today, and get growing!

- Lemon is sensitive to the amount of moisture.
He loves water and hardly tolerates even short-term droughts. Make it a rule to constantly water the tree, preventing the soil from drying out. Regular spraying will also be useful.
- The plant needs an excess of sunlight. That is why it is difficult to grow it in apartments where there is a lack of daylight. These can be ground floors or rooms with north windows. Under such conditions, the lemon begins to shed its leaves and wither.
- Lemon needs regular feeding. The fact is that he needs a lot of strength for flowering and fruiting, and the land with pots quickly loses nutrients. Every year the plant needs to be fertilized and only then the plant will be lush and begin to bear fruit.
- Nutritious earth mix. Acidified or neutral soil with a loose structure is suitable for growing lemons. This can be ready-made soil for citrus plants or a homemade mixture. To do this, sand, peat, humus and hardwood are mixed in equal proportions, after which a large amount of soddy land is added.
- Temperature conditions. In the summer season, the optimum temperature is 26 °C. With her, the tree feels comfortable, actively grows and develops correctly. In spring and autumn, it is better to lower the temperature in the room to 14 - 16 ° C. With the onset of winter, it is better to provide the lemon with a temperature regime of 7 to 12 ° C. But remember that the transition from heat to coolness should be smooth, the tree does not like sudden changes. In the summer season, lemon should be sprayed. It is best to do this in the evenings or on cloudy days. The main rule is that the sun's rays should not fall on the leaves during spraying, because. it may cause burns.
