How to Grow Dwarf Citrus Trees

Fragrant flowers. Beautiful, shiny, and evergreen foliage. Colorful, edible, and delicious fruits. A well-behaved root system. The ability to adjust to different types or methods of cultivation.

All of these make the dwarf citrus a valuable plant for modern home gardening.

Dwarf citrus trees are simply regular fruit trees that are grafted onto smaller plant rootstock. This means you get the tasty fruit of a normal citrus tree from a plant that works well in landscapes that can’t accommodate a full-size tree.

And most importantly, of course, smaller trees mean more easily accessible fruit! Dwarf citrus trees generally grow to be a maximum of 8 to 10 feet tall.

The fruit of dwarf trees is the same size and quality as that grown on a standard-sized tree, assuming it receives the same care. And dwarf types produce a larger crop, for their size, than standard-sized trees.

Let’s get to the tips, talk about techniques and things to be aware of, and hopefully we can even help you to find your perfect tree.

A Versatile Landscape Addition

Dwarf citrus — lemon, orange, grapefruit, lime, tangelo, and kumquat — has as many uses in the garden as there are places for plants.

You can use it as a hedge to mark a property line or to screen off a given area, or you can grow it as a specimen plant in the lawn.

You can use dwarf citrus to add a little height to a perennial background, or use it as a foundation planting close to the house.

It will make a lovely addition espaliered against a wall to break the glare, or simply to ornament it.

Espaliering is the process of training a tree, shrub, or woody vine to grow flat against a surface, usually a sunny and protected wall or a fence. This is often done with a specific geometric design in mind that can turn the tree into a rather breathtaking artistic statement. Or other trees are allowed to maintain their natural form, with protruding branches merely pruned off.

Dwarf citrus varieties are also quite suitable for container plantings. They bring significant interest to porches or patios as specimen plantings, and they’re convenient to access come harvest time. Close proximity to the house also means it will be easier to bring your plants indoors if you live in a climate where a citrus tree cannot overwinter outdoors.

Plenty to Choose From and Where to Buy

Dwarf citrus fruits are available in a number of types and varieties. Nearly every worthwhile variety of edible citrus in the world is now available to gardeners on a dwarfing rootstock.

If you’re looking for the lemony-orange flavor of Meyer lemons, consider this small tree, available from Nature Hills Nursery.

You’ll get a plant in a container that’s somewhere between two and three gallons. Dwarf Meyer lemon trees grow well in pots, where they will grow to 4 feet or so. And they do well in the landscape, too, in zones 9 and 10.

Dwarf Meyer lemon trees can reach 10 feet, but will easily adjust to less than four feet indoors.

If Clementine oranges make your palate sing, consider ordering a sapling from Brighter Blooms, available via Amazon.

You can choose a 1- to 2-foot tree or a 3- to 4-foot tree of the ‘Nules’ variety, which will produce copious amounts of sweet orange fruit.

Looking for lime? Consider a dwarf ‘Bearss’ seedless lime, available from Nature Hills Nursery.

Also known as the Persian, Tahini, or seedless lime, you’ll get an evergreen plant that is a minimum of 3 years old, and will grow to about 10 feet tall at maturity. This option does well in the landscape as well as in containers.

Looking for mini fruit to ornament your miniature tree? Nature Hills offers a dwarf ‘Nagami’ kumquat in a two- to three-gallon container that will grow to about 10 feet tall.

Kumquats are known for their edible peel and lively, tart flavor.

Morning or Afternoon – Just Give Them Sun

Like all plants, small trees have a few simple needs. And you need to attend to these if you’re aiming to produce beautiful trees with delicious fruit.

The first and most important of these needs is good drainage. While the roots must have a constant supply of moisture, they cannot tolerate waterlogged soil, or water that stands for too long. For a primer on drainage, see the green boxed-out reference section below.

Citrus trees also need warmth and sunshine to produce colorful, juicy, and flavorful fruit. I know of one gardener who has some trees that only get morning sun, and other trees that only get afternoon sun. In both locations, the plants do a good job of setting and ripening their fruits.

The Perfect Dirt

Plants grown in containers do best with the least effort when they are planted in a lightweight, perlite-containing potting mix that drains well. An all-organic matter or native soil will compact too quickly, reducing aeration for roots.

Commercial growers are fond of the “UC mix.” This was developed by soil scientists at the University of California Riverside’s world-renowned Citrus Research Center and Agricultural Experiment Station.

In addition to the special soil mixture for container-grown plants, the Citrus Experiment Station has developed new citrus varieties and worked to address disease and pest management, post-harvest handling methods, and practices for improved commercial fruit production.

UC’s soil mixtures have been so successful that commercial growers all over the western world are using them for all types of plants.

Unfortunately, unless you need a few cubic yards of this mix, and live in Southern California, backyard gardeners will likely not be able to find UC mix.

Instead, look for planting mixes that are specially blended for citrus or fruit trees.

When setting plants out in the garden, the citrus-specific planting mix should be combined with the soil removed from the hole in a ratio of one part mix to one part native soil.

As plant roots are generally reluctant to enter a new growing medium, mixing a citrus-specific soil with the native soil will make the tree’s transition easier.

Keep in Mind: Drainage Is Essential

Appropriate drainage is the #1 need for citrus plants. Overwatering causes citrus foliage to drop off. Under-watering can also cause this trouble, but drooping foliage usually calls attention to the lack of water in time to ward off serious leaf drop.

There is seldom any overwatering problem in containers if a well-draining soil is used. In garden soil, excess water must have a means of escape. If the soil has naturally good drainage, there is little to worry about.

Here’s how to check for well-draining soil in an existing area where you would like to plant, and what you can try if you have a problem:

  • Dig a hole of the needed size and fill it with water, keeping the water running until the soil all around the hole is saturated.
  • Check the time it takes for the water to drain completely through the saturated soil. If it drains away within a couple of hours, there is no drainage problem.
  • If water stands in the freshly dug hole for longer than two hours, however, something should be done before a plant is placed.
  • One way to address this is to dig the hole a foot deeper than is needed. Slope the bottom of the hole at a steep angle and dig a trench from the low side leading away from the planting area. Fill the bottom of the hole and the trench with 6-10 inches of drain rock or gravel.
  • Be sure the trench is long enough to carry off heavy winter rainwater. Fill in above the rock with the half and half mixture of the citrus soil and native soil and set the plant in place.

When transplanting your tree, set the root ball high in the hole, high enough for the soil over the finished job to slope from the tree trunk to the surrounding soil level.

The top of the root ball should be two or three inches higher than the surrounding soil level. Backfill with your soil mixture, but create a shallow “moat” around the circumference of the newly planted tree. If you were unable to find a citrus-specific potting mix, scatter half a cupful of balanced fertilizer around the moat.

Add a layer of mulch around the planting area, including in the moat. Slowly fill the moat with water. Keep the water dribbling away in the full basin for half an hour or so, wait two or three days and do it again, then leave the plant alone until it needs watering.

Shaping: It’s Up to You

Young plants may look a little one-sided, but give them a few years and they will become neatly rounded specimens – unless an espaliered miniature growing along a fence or garden wall is what you’re after. They can be trained to do this as well.

If you want to keep the plants quite low or add fullness, you can pinch out the tips of the new growth from time to time.

You’ll also want to prune away any deadwood, and prune to maximize airflow. Prune off any branches that cross others and prevent sunlight from reaching the lower branch.

Fertilizer? Only if They’re Really Hungry

In general, these little trees do need fertilizing. You can be as fancy or simple as you like with this garden practice.

If your plants appear to need some nutritive love, a 10-10-8 fertilizer with an acid reaction, such as what you would use on camellias and roses, should keep the plants growing if you follow the directions on the package.

Or, if you like to play around a bit, you can leaf spray with zinc and manganese in the spring before growth starts and then supplement with a spray containing nitrogen. Any iron deficiency can be cared for with iron chelate.

Bugs, Be Gone!

Like all plants, dwarf citrus is bothered by common pests such as ants, snails, aphids, thrips, and spider mites.

Get rid of ants and spider mites with diatomaceous earth. And check out this article for ideas about how to naturally rid your garden of snails and slugs.

Treat aphids and thrips with a hard, firm spray with the hose, or an insecticidal soap such as this one from Garden Safe, available on Amazon.

Sometimes citrus gets scale. Be watchful for this pest and pick it or water-blast it off before it can become an infestation. A spray made from neem oil is the only really effective cure for these pests.

More to Watch out For: Diseases

Citrus suffers from its share of bacterial and fungal diseases, also.

A fairly recently arrived and particularly devastating illness that is plaguing US citrus trees — both commercial and backyard — is huanglongbing, also known as HLB, yellow dragon disease, or citrus greening disease. Presence of the disease has been identified in Florida, California, Louisiana, Georgia, South Carolina, and Texas.

Originating in Asia, and first reported in the United States in 2005, HLB is spread by a pest called the Asian citrus psyllid.

Symptoms include asymmetrical yellow discoloration on leaves, and fruit that only partially ripens.

There is no cure for an infected tree, which will die. The best prevention is to immediately treat an infection of Asian citrus psyllid with neem oil, insecticidal soap, or horticultural spray oil.

For more information on preventing and treating this disease, you can read our full article here.

Another disease to look out for is citrus canker, a bacterial disease that causes lesions on the leaves, stems, and fruit of plants. There is no cure for this highly contagious disease; it is spread by wind-driven rain, contact with infected tools or hands, or by birds. Infected trees must be removed.

Melanose is a fungal infection that is best contained by pruning affected areas. It presents as small, dark spots on leaves and scabbing on fruit. A fungicide, such as this one from Bonide and available via Amazon, may be helpful if the infection is caught early.

Bonide Products Fung-Onil Ready-to-Use Fungicide, 32-Ounce

This 32-ounce bottle is ready to use.

Greasy spot is another fungal problem, characterized yellowish-brown blister spots on leaves. Sooty mold is also caused by a fungus, and it causes a blackening of the plant’s leaves.

Root rot, sometimes called brown or collar rot, is caused by soil-borne water molds. With this one, you’ll see dark brown patches of hardened bark on the tree’s trunk.

Harvest: When Are They Ready?

Eating the fruit that you’ve grown is the most rewarding part of the process. Different types of citrus fruits ripen at various times of year. In the south, for example, most orange varieties are typically ready to pick December through May. Mandarins are usually ready in January through April. Lemons and limes ripen all year.

Consult the planting information that came with your tree when you purchased it to know approximately when its fruit will be ready for harvest.

The fruit signals its harvest readiness by turning from green to its ultimate color. In some cases, the fruit will simply drop from the tree when it is ready to eat.

A boy with brown hair and a mint green collared shirt inhales the aroma of a dwarf clementine tree with round orange fruit and shiny green leaves with his eyes closed, on a white and tan background.

Be sure to pick up dropped fruit right away because a) you want to eat it, and b) you want to keep a tidy garden to prevent disease!

You can also perform a taste test. Pull a couple of sweet- and fresh-smelling fruits from different places on the tree, cut them open, and sample.

Michelangelo-Perfect Palate Pleasers

When it comes to eating your citrus fruit, there is no shortage of options. Fresh from the tree is best for some, but with so many recipes utilizing citrus, we suggest exploring ways to incorporate this versatile fruit into drinks, sides, main courses, and desserts.

Here are a few suggestions to get you started:

The classic combo of tequila and lime partner up in Tequila Shrimp Tacos with Jicama Cucumber Slaw, a quick-fix recipe from Vintage Kitty. Pluck a few limes to flavor the slaw, and a few more to squeeze over the finished tacos. And maybe some more for the accompanying margaritas — here’s a recipe for a delicious Mango Madness Margarita from Shola over at Our Perfect Palette.

If you’ve got a grapefruit tree, consider adding this Grapefruit and Fennel Salad to the menu. From our friends at The Fitchen, this recipe also features onion and avocado. And it also calls for lemon juice, so you’ll be able to make use of more than one homegrown citrus fruit.

Collect a few lemons for this Sheet Pan Chicken Piccata, from Hunger Thirst Play. Capers and lemons go together like Michelangelo and the Renaissance, and this classic Italian dish highlights the flavor profile perfectly.

You can put The Gingered Whisk’s Mini Meyer Lemon Donuts in either the dessert or breakfast category. Crafted with buttermilk and topped with a sweet icing, these baked morsels are tasty any time of day.

Don’t miss an opportunity to juice one or two small oranges for this light and fluffy Gluten-Free Mandarin Orange Sponge Cake from our sister site, Foodal. This lactose-free dessert is moist and delicious.

All the Flavor in Much Less Space

These miniaturized fruit trees are a wonderful solution for gardener-cooks who want the convenience and deliciousness of home-picked fruit, but don’t have space for a large tree.

Year 3. Grapefruit tree. Height 6’
Year 1. Orange. Height 4’

I noticed giving the tree a large dose of fertilizer causes it to flower. This especially wonderful during the winter time as it fills the house with the smell of lilacs.

What is the limit for fruit? I have now 150 blossoms on my tree. I bring the tree indoors from September to the middle of May.

I started some lime seeds from a lime I bought about 3-4 months ago. I’m not sure what kind they are but I had 6 that sprouted. Two are still alive and are about 6 inches tall. They seem to be slow growing. I love the dark green leaves and they are sitting under a table lamp. My question is when should I plant them outside or should I just keep them in pots and prune to keep small to bring indoors during winter? I live in southern Oklahoma.

Hi Bobbie, Southern Oklahoma ranges from USDA hardiness zones 7b to 8a. Citrus can do well outside in this climate with some protection in the winter, but you may do better to keep your seedlings in pots until they mature into sturdy saplings. This will give you more control over watering as well. Harden off your seedlings gradually, giving them an hour of partial sunlight in a protected area outdoors, and increasing by an hour each day before bringing them back inside. This will help to strengthen your plants, so they’re able to withstand outdoor conditions this spring. When they… Read more »

Hi Natalie, This all depends on the size of the plant, and many will be delivered in 2 to 3-gallon containers from the nursery. These will need to be transplanted into something slightly bigger after you receive them or bring them home, planted with additional citrus potting soil in containers with plenty of drainage holes. But you don’t want these pots to be too big, since planting something small with a lot of soil will make providing the proper moisture level a bit of a challenge. Pots need to be big enough to provide the same depth to which they… Read more »

hello Gretchen
You gave some good tips about shaping. I have a 2 foot border along the house where I would like to place a potted dwarf eureka lemon. So I would be limited to little over a foot radius to the house. Could the branches be pruned to keep it off the house and yet produce more than just a couple lemons? Appreciate your expertise.

Great article and very helpful. I’ve managed to keep a dwarf clementine and lemon alive despite some of the oops you mention above. I harvested my first clementines, but they are incredibly tart!! Have I done something wrong in growing them or since this is season #1, will that change? I have I waited too long to pick them? Thanks!

Is there special seeds for dwarf tree fruits or whatever or you make them dwarf by pruning

Guest (@guest_6151)

My table top lime plant came with some fruit, which we harvested a couple of times. I then transplanted it to the ground where it is growing large nicely, but no more signs of fruit. Any ideas if it will produce fruit again now that it is in the ground and much larger in size? Thanks for any suggestions.

Thanks for getting back. I transplanted it about 9 months ago. I watered it with miracle grow, thus far, but no specific fertilizer other than that. I have most recently treated it with Bayers insect control because of leaf miners.

Thanks for the additional information. Based on your information, this is my best hypothesis of why your lime tree isn’t bearing fruit this year: Sometimes citrus trees will only bear fruit in alternate years – particularly if they have had a very heavy crop the previous year. This may be the case with your tree. It was probably encouraged to produce a lot of fruit by the grower prior to sale to be even more enticing. Who doesn’t want to buy a lime tree covered with limes? 🙂 Young citrus trees generally don’t produce fruit for the first few years… Read more »
