How to Grow Oranges in USA: Check How this Guide Helps Beginners in Orange Farming

Orange is the fruit of various citrus species in the family Rutaceae. Oranges are a great source of vitamins, especially vitamin C. The United States is the world’s second-largest producer of oranges, accounting for about 10 percent of the world’s production. Florida is the Orange growing state for 70% of the nation’s production.

Where is Orange grown in the US? 

The top orange-growing states in the United States are California, Florida, Texas, and Arizona. Florida continues to sustain significant losses due to citrus blight. The disease has not yet materially affected California orchards. The Sunshine State’s production is split between the Valencia and Navel Orange varieties. Orange trees can mostly be grown in USDA hardiness zones 9-11.

And for the continental United States, the range ends in zone 10, especially in southern Florida, Texas, and California. Remember that hardiness zones aren’t just based on how far north or south the crop is grown. As you will see, some areas in states like Oregon and even Washington State where you can grow Orange citrus trees. If you grow Oranges in a zone 8 area, grow certain Orange types, such as Blood Oranges and Valencia. 

What are all the different types of Oranges? 

  • The bulk of the US Orange crop consists of three main cultivars: Washington NavEl, Valencia, and Hamlin, supplemented by several other cultivars such as ‘Pineapple,’ ‘Homosassa,’ and Queen.
  • Washington Navel has a thick, easy-to-peel peel and is easy to split, making it one of the most edible Oranges. However, it is not a good variety for processing into juice, as the high limonene content makes it bitter. 
  • Valencia Oranges are smaller and juicier than Washington Oranges, with thinner peels, and are known for having juice with fewer seeds. Valencia can also produce two overlapping crops per year. Almost all of the world’s Orange juice production comes from Valencia Oranges. However, Valencia Oranges can also be eaten fresh. 
  • Valencia fruit is moderately large. At maturity, it has an elongated to spherical shape. Valencia has high heat requirements to mature, which are met only in the hottest areas. In the US, such conditions occur only in Florida, the Rio Grande Valley of Texas, and the least arid regions of Arizona and California. 
  • In such areas, Valencia Oranges usually ripen in January or February and are kept on the tree for several months after ripening, even until flowering. Consequently, in many areas, trees usually bear two crops, the old (Oranges that are ripe or near ripe) and the new, which are flowering or fruiting. Valencia ripens in summer in areas with mild winters and moderates to low overall temperatures during the growing season. It is an important variety in Florida and California and represents about half of the US Orange production. 
  • Navel Oranges are primarily eaten as fresh fruit. Secondly, navel Oranges are used as an additive in juice. They are generally not suitable for juicing as their juice becomes less juicy during storage. The fruit is usually seedless and larger than the Valencia Orange. The most important varieties of navel Orange are Washington Navel or Navel Washington or Bahia or Merlin. In the US, Washington navel Oranges ripen in the fall, and the fruit typically stays on the tree for 3 to 4 months. 
  • Hamlin is similar to Valencia – juicy and flavorful, but with lighter-colored fruit and juices. It is seedless and also popular for juicing. ‘Pineapple Orange’ is a seeded, mid-season variety with rich color and flavor, and Queens are similar but hardier and more tolerant of cooler and drier temperatures.
  • Ruby/Blood Oranges – Blood Oranges, named for their red flesh and strong flavor, continue to gain popularity. They are grown selectively in Florida, but most originate in the Mediterranean. These Oranges are small, have fewer seeds, and are flavorful. They are named for the deep red color of their fruit. Another special Orange is Bergamot, which looks like a lemon or lime, and has a sweet floral scent. 
  • Washington Navel Oranges – Large, seedless Oranges that are usually easy to peel.

Who is the largest producer of Oranges in the US? 

Last year, Florida produced 67.4 million boxes of Oranges, while California produced 54.1 million boxes. A year ago, Florida produced 52.2 million boxes, compared to 71.85 million in California. The main varieties are Navel, Hamlin, Pineapple, Ambersweet, and Valencia. The fresh Orange season usually runs from October to June. The main types of Florida grapefruit are Ruby Red, Flame, Thompson, Marsh, and Duncan. 

Most of Florida’s Orange crop is grown in the central part of the Florida peninsula, particularly in Polk, Desoto, Highlands, and Hendry counties. Passing through these places, one can see acres upon acres of beautiful Orange groves. Orange growers produce different Oranges depending on the season, which are produced for different purposes. The juice is poured into many large juice plants, filling the air with the scent of fresh Oranges several times a year. 

When do Florida Orange trees bloom? 

Like any fruit tree, Orange trees bloom to maximize their chances of reproductive success. In other words, Orange trees bloom for reproduction, so the trees like to flower and bloom after Florida’s “harsh” winter months. Orange trees typically bloom sometime in March, when temperatures climb back into the Florida summer. 

Once Orange trees bloom, they go through three “drops.” The first drop comes at the end of blooming when the trees drop the non-pollinated flowers from their branches. After that, the trees will experience a second drop when the baby fruits are marble-sized. These early fruit drops help keep citrus trees healthy and channel resources into the most viable fruit. The final drop comes when it’s time to harvest the Oranges: they begin to ripen and fall from the trees.

How do you make an Orange grow faster? 

  • The most important thing you can do to encourage Orange tree growth is to ensure you provide enough light for your tree. Light helps the tree generate the energy it needs to power fruit production. Plant it in full sun to ensure the tree gets enough light. 
  • To grow Oranges effectively, remember that trees need nutrients, water, and sunshine more than anything else. The production of sweet, juicy fruit can take a lot of nutrients from the soil. So, if you want the fruit tree to grow big, the best option is to use a nitrogen-rich fertilizer. 
  • If Orange tree size is a priority, your best choice may be a Navel Orange. Regular watering is also key to making your Orange trees grow faster. 
  • Orange trees need a good balance of nutrients to grow rapidly. A citrus fertilizer is the idea and will give the tree everything it needs to grow quickly and produce fruit. An excellent alternative is organic fertilizers such as chicken manure and fish emulsion. Mix it with a dose of iron chelates in the spring, and your plant will be happy. 

What climate do Oranges grow in? 

Orange trees are grown successfully in tropical and subtropical climate conditions for their sweet fruit. Climate is the most important parameter for selecting an Orange farm location. Climate largely determines the success of Orange farms and the quality of citrus fruits, while soil and water generally determine the productivity of Orange trees. Cold is the main enemy of the Orange tree.

In the United States, Orange trees are grown commercially in the southern states (California, Texas, Arizona, and Florida). High temperatures can also be important for tree productivity. Strong and cold winds can also cause damage to trees, stunting, loss of fruit, and poor quality. Orange trees prefer light to medium-textured soil with good drainage and free-standing water. Oranges do not grow well in a land where other citrus fields once stood. It is attributed to the accumulation of certain toxins in the soil over time and the presence of certain pathogens. 

A suitable place to plant an Orange field is usually downhill, resulting in a smooth surface where cold currents can flow freely. Soil erosion on such a site is mainly avoided by installing low-lying grass areas between rows of tree plantings. In highly sloping soils, it is better to build terraces. Satisfactory yields are obtained in soils with pH 5.5 (slightly acidic) to pH 6.5, but the tree can tolerate pH 4.5 to 8. Orange is a salinity-sensitive crop. Thus, the growth and productivity of trees can be limited if the water contains high salinity levels. 

Which state is best for growing Oranges?

Florida’s climate is ideal for growing the best juicy Oranges for 100% Orange juice. Florida offers all the key ingredients to produce a bountiful, high-quality crop with its subtropical temperatures, abundant sunshine, distinctive sandy soil, and ample rainfall. Newly planted trees require adequate irrigation to ensure they become established. During the first year of planting, water should be applied at the base of the stem to keep the root ball moist so that the roots can set into the soil. 

How to grow an Orange tree? 

  • Orange is a delicate crop that should be planted six weeks after the last frost date when air and soil temperature levels are consistently warm. Because of the year-round warmth, residents of the commercial citrus belt, stretching from southern California to Florida, can grow Orange trees anytime. Before planting, consult your plant hardiness chart to see if your location is suitable for growing citrus year-round. 
  • Oranges can be grown in USDA hardiness zones 9-11. If you live in one of these hot climates, you can find a place to put the tree outside: Choose an area that is sheltered from the wind but sunny. 
  • Plant standard-sized trees at least 12 feet from walls and other significant obstructions and 25 feet from adjacent trees to allow for root growth. Plant trees at least 5 feet apart to keep walkways clear.

Are Florida or California Oranges better? 

Oranges in Florida are relatively sweet and juicy compared to their Californian counterparts. On the other hand, California Oranges retain freshness longer because of their thicker peels. 

Do Orange trees grow all year? 

  • Each tree produces one fruit crop yearly, with some species taking up to 10 months to complete their fruiting cycle. 
  • Oranges are traditionally harvested in the winter, but new varieties and cultivation techniques allow harvesting all year round. 

Which fertilizer is best for Orange trees? 

  • When fertilizers are applied at the right time, trees get all the nutrients they need to grow and produce fruit, but improper application can cause tree burns or other damage. 
  • Use a citrus tree fertilizer made specifically for citrus trees for plant growth or also use a nitrogen-rich fertilizer. Two tablespoons of nitrogen-rich fertilizer should be sprinkled under young trees of 2-3 years of age three or four times a year before watering. Mature trees four years or older growing outdoors need 1-1.5 lb of nitrogen per year. The nitrogen ratio of your fertilizer should be specified, so you can estimate how much fertilizer you need to get the right amount of nitrogen. Spray the tree’s root system and water once a year. 
  • Fertilization of growing Orange trees depends on the use of fruit—excess nitrogen fertilization results in more oil in the pods. Potassium fertilizer reduces the oil in the peel. For high yields of edible Oranges, 1 to 2 pounds (0.5-1 kg) of nitrogen per tree should be applied annually. 
  • Fertilizers should contain potassium and phosphorus as well as a range of micronutrients. If the older Orange tree is not producing abundant fruit, take a soil test of the area where the Orange trees are growing to determine what fertilizer ratio is needed. Additional fertilizer is often applied once or twice a year by sprinkling the tree leaves. 

When should you prune an Orange tree in California? 

February through April is Southern California’s best month to harvest citrus trees. Please wait until the tree has stopped fruiting before it begins to flower in the spring.

How do you prune an Orange tree in Florida? 

  • The best time to harvest lemons is after the danger of frost has passed, which is usually between late February and early March. After that, you can do reduction cuts, which is the pruning of lateral or side limbs at the top of the Orange tree to prevent it from getting too tall. 
  • Pruning is the most important aspect of knowing how to grow an Orange tree with great-tasting fruit and high yields. You are improving the overall health of your tree while encouraging growth through pruning. Often tree branches can grow incorrectly, causing unproductive branches, crowding, and other problems that will affect your harvest. 

Do Orange trees survive winter? 

Orange trees can tolerate temperatures between 35 and 55°F. Fruiting trees can tolerate cold weather with temperatures as low as 27°F, but if the temperature drops below that, it can damage the fruit. Most trees are dormant and do not bear fruit in winter, but Oranges are an exception. Their prime days are the winter months. Oranges like cold climates but not freezing temperatures. They say the cold sweetens the Oranges and brings out the vibrant color of the skin. In southern Florida and California, winter is the citrus season. 

How do you grow Orange trees from seeds? 

You can extract the Orange seeds straight from the fruit. 

1. Soak the seeds in water – The Orange seeds first need to sit in water for at least 24 hours. Discard any Orange seeds that float to the top after a day. 

2. Prepare your soil – You can use the traditional potting mix to grow Orange tree seeds. Place your soil in a tray and plant the seeds in holes about an inch deep. Cover with soil, and add any compost or mulch to add nutrients to the soil.

3. Keep in a warm place – Once seeded, place your seeds in a warm, moist location with access to indirect sunlight. Once the seeds begin to germinate, you can remove the cover. Keep in a warm place with sunlight. If natural light is low, supplement with the growing light. 

4. Transfer to individual pots – The seeds must continue to germinate and grow. When transplanting, keep the root ball undisturbed. Plant in a large pot so the tree can accommodate deep roots in well-drained soil. Keep in a warm place indoors with access to direct sunlight and good air circulation. Make sure your planter has drainage holes. 

Understand the problems of growing from seed – An Orange tree grown from seed is more prone to disease, and its Oranges may not taste the same as the fruit from which the seed came. It may take four to fifteen years for the tree to bear fruit for the first time. A young tree purchased from a nursery combines two plants: one tree bred for healthy roots and other attributes, plus branches from another tree grafted onto the first. These branches come from an Orange tree that produces high-quality fruit and are already mature; the tree should bear fruit within a year or two after purchase.

Where are Oranges grown in Florida? 

Most Oranges in Florida are grown in the southern two-thirds of the Florida peninsula, where freezing is less likely. 

What are the pests and diseases of Orange? 

Oranges are susceptible to several molds and rots, especially after harvest, including green mold, blue mold, stem end rot, brown rot, and sour rot. Prevention includes proper handling to avoid physically damaged fruit, treatment with fungicides, rapid cooling after harvest, and proper storage temperature. A serious challenge for Orange growers is Huanglongbing (HLB), also known as citrus greening.

Based on bacteria, it causes bitter and malformed fruit and eventually kills the trees. It has been particularly devastating in Florida and is spreading to other citrus-producing states. To address the problem, USDA is working with commodity groups and growers in an emergency response group, allocating millions of dollars to find solutions. In addition, citrus canker, another bacterial disease, was brought to Florida. It causes early fruit and leaf drops as well as fruit lesions. 

How do they harvest Oranges in the USA? 

To harvest Oranges, you will need a sharp tool, such as scissors or a small knife, to remove the Oranges from their stems. You can also use garden gloves to pick the fruit by hand. Once picked, Oranges are no longer ripe. Oranges usually last between two and three weeks. Oranges reach acceptable ripeness about 6-12 or even 14 months after flowering and can be harvested 2-3 months before overripe. T

he best time to harvest Orange fruits depends on the variety and region. In the US, navel Oranges are often harvested from October to June, while Valencia Oranges are often harvested from March to October. Florida citrus growers report that they can harvest Oranges all year except summer. You can tell it’s Orange harvest time when you see some ripe Oranges falling from the tree. However, the harvest time is different when it comes to Oranges for juice production.

In this case, growers are busy not only checking the external characteristics of the fruit for harvesting. Fruit production companies require specific features such as acidic sugars and essences to buy fruit. Thus, producers use special portable instruments to measure these parameters. Oranges are traditionally harvested by hand, with a combined pulling motion by twisting the wrist. Some growers use shears or shears and cut the stem. It is very common when harvesting fruit with a very thin crust.

However, over the past decade, there has been a strong trend to introduce mechanical harvesting, particularly in Florida, US. Farmers use large shakers attached to tractors to reduce costs through labor-saving technology. In less than 15 minutes, machines shake 36,000 pounds of Oranges from 100 trees, grab the fruit, and put it into a large storage car. It would have taken four pickers all day.

According to the New York Times, these sophisticated machines work best only on large, regularly spaced, mature young groves in the Southwest and on smaller, larger, more irregular areas in some central Florida. Using machines on Valencia’s Orange trees is difficult, as shaking those risks prematurely losing much of the next year’s crop.

How much can you make from an acre of Orange trees? 

  • An average healthy and mature Orange tree produces 200-350 Oranges. However, experienced Orange growers can harvest between 400 and 600 Oranges per tree after years of practice. 
  • Under a dense planting system, with 400 trees per hectare, the expected yield of an experienced farmer would be 40-50 tonnes per hectare.

Conclusion

More than 90 percent of the Oranges majorly produced in the United States go to make juice. The important things to remember when planting your Orange tree are how to plant and care for your Orange fruit. Remember that planting instructions will vary depending on the type of Orange you choose, but all Orange trees should be planted in suitable growing areas.

The most important variables for your tree will be adequate sunlight and water. This article will explore the best ways to make your Orange tree grow successfully in the USA.
