The sweet orange reproduces asexually apomixis through nucellar embryony ; varieties of sweet orange arise through mutations. The orange is a hybrid between pomelo Citrus maxima and mandarin Citrus reticulata. The orange originated in a region encompassing Southern China , Northeast India , and Myanmar , [8] [9] and the earliest mention of the sweet orange was in Chinese literature in BC. The fruit of the orange tree can be eaten fresh, or processed for its juice or fragrant peel. All citrus trees belong to the single genus Citrus and remain almost entirely interfertile. This includes grapefruits , lemons , limes , oranges, and various other types and hybrids.

12 delicious fruit trees for the Bay Area

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. Dwarf citrus trees are simply regular fruit trees that are grafted onto smaller plant rootstock. 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. We link to vendors to help you find relevant products. If you buy from one of our links, we may earn a commission. 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.

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. 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.

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. Improved Dwarf Meyer Lemon Trees. 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 andDwarf 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. Looking for lime? Bearss Lime Tree. This option does well in the landscape as well as in containers.

Looking for mini fruit to ornament your miniature tree? Nagami Kumquat. Like all plants, small trees have a few simple needs. 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.

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. 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.

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. 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. 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.

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. 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. 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. Prune off any branches that cross others and prevent sunlight from reaching the lower branch. 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 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.

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.

Try this neem oil extract concentrate from Garden Safe, available from Amazon. 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. 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, such as this one from Bonide that you can purchase via Amazon.

Dilute this concentrated product according to package directions applying chemicals article , depending on what plants you are treating.

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. Greasy spot is another fungal problem, characterized yellowish-brown blister spots on leaves.

Root rot, sometimes called brown or collar rot , is caused by soil-borne water molds. 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. 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. 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.

Create Small Fruit Trees with This Pruning Method

Shop for trees at least two to three years old — the age when they're mature enough to produce and support fruit. Garden retailers know this information, so you don't need to become a pro overnight. Trees may seem small now, but even with dwarf varieties and regular pruning, most container citrus trees will eventually measure near 6 feet tall. Citrus trees prefer their soil evenly moist and never soggy. Soil that stays too dry or too wet spells trouble.

Facts and Myths Associated with "Hedge Apples"

Hi, we are growing about 10 different citrus including oranges. The oranges all seem to be quite sour. I have sprinkled Epsom salts around - is that going to be enough to help? Also, how can I stop the fruit and leaves getting black scum on them? Thanks, Leah.

Orange Tree Harvest and Yields

Prized for their dark green foliage, fragrant blossoms and juicy fruit, it can be disappointing when the fruit produced by your orange tree is smaller than normal. Small fruit problems indicate your tree is stressed by nutrient deficiencies, insect pests or infection. Zinc deficiency is characterized by uneven green bands along the leaf veins and midrib, with the remaining tissue turning a light yellow to whitish color. In the early stages of zinc deficiency, leaf size is unaffected, but when the problem becomes severe, the leaves become small, narrow and tend to stand upright. The fruit of orange trees suffering zinc deficiency will also be smooth and light colored, with low juice content.

Orange trees commonly don't produce fruit if they're not mature yet, your orange tree can provide minimal fruiting or fruit that are too small and sour.

Why do my orange trees have no fruit? Blame pruning, watering

Fruit thinning for homeowners is one of the most difficult jobs to do when producing tree fruit. With all the expense and hard work that has gone into producing a healthy productive tree, the last thing homeowners want to hear is that they should knock the majority of the young fruit on the ground. However there are a couple of important reasons why fruit crops should be thinned. Most deciduous fruit trees benefit from fruit thinning.

Oranges are considered subtropical but will grow in most areas of NSW and Queensland. Like other citrus, orange trees grow best in deep, well-drained soil, in plenty of sun. Work a few bucket loads of well-rotted manure into the planting hole, or substitute with a single bucket load of chook pellets. Add some rock minerals to supply slow release nutrients and, after planting, water the tree in well with seaweed extract. To keep your tree happy over the long term, keep it very well fed.

Summer fruits are among the most delicious things we eat, and ripe summer fruit from your own garden is even better.

Growing Orange Tree: Best Varieties, Planting Guides, Care, Problems and Harvest

Make a donation. Citrus are not hardy in Britain but can be grown in pots outdoors in summer and brought inside for winter. Of all citrus, most gardeners grow lemons; kumquats are the most cold tolerant; others, like limes and grapefruits, need more warmth. The fragrant flowers can appear all year round, but are especially abundant in late winter. Fruit ripens up to 12 months later, so they often flower and fruit at the same time. Citrus in pots can be put outdoors in summer, in a sheltered sunny position, but only when temperatures increase, from mid-June until late September.

The prospect of growing fruit trees can be daunting — pollination groups, complicated pruning involving spurs and tips, countless tricky pests — but choose your variety wisely and you can sidestep many of the scarier aspects of fruit cultivation. Then look forward to delicious summer harvests year after year — maximum reward for minimum effort. Apricots are members of the Prunus family, all members of which are best left unpruned to minimise the risk of canker and silver leaf diseases, both of which can enter the tree through pruning wounds. If any misplaced or damaged branches need removing, prune them out during the height of summer.
