Introduction

Tropical citrus like oranges will only grow in warm areas, so you should be living in zones 9 to 11 in order to grow oranges in your garden. Southern United States, South America and various parts of Southeast Asia are ideal for growing oranges. Cool areas can still have fresh oranges if you grow a small tree in a container and keep it protected over winter.

There are many kinds of oranges to choose from, each with their own unique flavor. Navel oranges are good for fresh eating, and Valencia are usually grown for their sweet juice. Blood oranges are distinctly red inside and even produce a reddish juice.

Oranges are almost exclusively eaten fresh or juiced. The juice is used in cooking and baking, but the fruit itself seldom is. Oranges are famous for their vitamin C content, and they also have fiber, vitamin A and even calcium. Their fragrant peels can be used to freshen up a room in potpourri.

Starting Your Tree

While you can probably get a seed from a supermarket orange to sprout, you will not get a resulting tree that matches that type of orange. Not to mention you will have about 10 years to wait before getting any kind of harvest. Most people buy seedlings instead.

When you go to the nursery, you’ll probably find that most orange trees are grafted. The orange branches have been fused with the rootstock of another tree. Don’t let that deter you when buying. The oranges will produce true to form, depending on the top of the tree, not the bottom. Grafted trees usually start to produce fruit for you the quickest.

Depending on your variety, an orange tree can get between 12 and 30 feet tall and have branches that spread around 10 feet across. It’s important to remember the final size when you pick your tree location. Oranges will also need a sunny location with well-drained soil.

Dig the hole for your seedling large enough to hold the roots without having to bend or break any of them. Soak the roots before planting them and make sure the grafting union point is kept well above ground level. Keep your tree well watered through the first season.

Tree Care

Orange trees need a lot of water. If there isn’t regular rainfall in your region, prepare to give your trees a deep watering every week through the hot weather of the summer. Adding a thick layer of mulch around the tree will help keep moisture in the soil.

If you’ve grown other fruit trees, you’ll be happy to know that oranges are one of the few that you really shouldn’t prune. Let the tree grow naturally for the best fruit harvest. That also means that your tree will be much taller than a pruned tree. You’ll need a ladder to get the fruit from the upper branches.

Regular fertilizing is extremely helpful for heavy-feeding orange trees. Giving them a feeding with standard fertilizer mixes at least twice a year is typical. There are some fertilizer products available formulated specifically for citrus trees as well.

Containers

One of the great things about growing a miniature orange tree in a pot is that you can move it somewhere sheltered during the winter. That means you may be able to grow oranges in areas cooler than the usual zones. Your tree should be able to stay outside as long as the temperature (both daytime and nighttime) stays above 40F.

You can get just about any kind of orange in “dwarf” variety because they are usually just standard orange trees grafted onto dwarf rootstocks.

Use a large container that has very good drainage. They like water but not soggy roots. You will have to water your tree at least once a week if not twice. If the soil is dry for an inch on top, you should water again.

Pests and Diseases

Orange trees can be subject to a number of problems. One of the most common is scale, which is a brownish insect that looks like a round bump or scale on the branches of your orange tree. Some species of scale are almost transparent, making them nearly impossible to see. Not only do they slowly suck the juices out of your plant, they give off a sweet sticky substance themselves that attracts more insects and can cause mold growth too.

A spray of diluted rubbing alcohol can kill them, but most typical insecticide sprays won’t do much good because of their tough shell. A foliage cleaner spray is designed to help with scale. It makes your orange tree leaves slippery, and the scale tends to drop off.

Ants love the liquid they give off (its called honeydew), so if you see a lot of ants on your orange trees that is a good indication that you have a scale problem. The ants themselves don’t usually harm your tree.

Mites are another tiny insect that can cause big problems. Orange trees are susceptible to citrus rust mites as well as spider mites. They are very small, and look like fat little spiders. Mites can cause your leaves to curl and brown. You can spray your trees with dormant oil in the early spring to help kill them off, or use insecticide later in the growing season.

Harvest and Storage

Your harvest season will vary greatly depending on what variety of orange you are growing. Valencia oranges will ripen between March and June, but many navel oranges ripen after December. A new orange tree will usually start to produce a fruit harvest about 2 years after planting.

The fruit will turn completely orange and have lost their green when they are ripe. Taste one to make sure they are at their sweetest. Either clip the fruit from the stem or twist it off carefully so you don’t damage the rest of the branch.

You can store oranges at room temperature for up to 2 weeks with no problem. If you keep them in the fridge, don’t keep them in a plastic bag or they may mold.

    I really enjoyed reading what I can do for my one and only dwarf orange tree. Can you put dried leafs for mulch or do you have to buy mulch? I am new to any type of landscaping and I live in Southern CA with a rock front and back yard. I think I have the ugliest front and backyard in the whole town. I am 71 years old and am trying to make our yards pretty.
    Thank you,
    Jeannie

  10. Jason  Says:

    We live in Phoenix, AZ and moved into a house about six months ago that has an orange tree in the yard. A few of the oranges have been the best oranges I have ever had, juicy and delicious. Most though (like 10:1) are dry inside and have no flavor at all. Any advice?

  11. diana  Says:

    I am in Ct. with a 7′ tree grown from a sprig in an envelope from Disney World in 1995. This year I got blossoms. Surprise! All other years only thorns. It is indoors in winter and I have fertilized it. But the flowers seem to be browning and dying. Some leaves are curling but are shiny. Could this be mites and what & where do I find dormant oil? I REALLY have waited for an orange! I don’t want to blow this season.
    Thanks.

  12. Jason Mcgehee  Says:

  13. Stefani Eaton  Says:

    Hi there!

    I just moved into a house a few months ago in Central California, and was happy to find we have an orange tree! After moving in i went and picked a few and was sad to find out they were all sour! After looking up a few things online i have come up with they are either sour oranges great for marmalade or they went sour during the frost of winter.

    Recently i noticed little buds coming up on the tree, showing new growth (Im assuming anyways) Do i need to pick all the oranges that are still on the tree off? Or will they just slowly fall off on there own with the new growth?

  14. Mark  Says:

    I have an orange tree that produces lots of fruit. However, the fruit is dry inside and does not have much flavor. It is “pithy”. Any helpful suggestions?

    Sorry.
    Rgds, Hugh Pearson

  17. Ali Hamid Khan  Says:

    The oranges on my trees fall off prematurely. They can’t stay long enough to ripen. What should I do?

    How often should I fertilize orange trees and what chemical fertilizers should I use and in what proportion?

    Hi, we live in southern Spain and have got a standard orange tree in a large container. Last year we had 5 oranges which were very good and this year no blossom but the leaves are very sticky underneath and curling a bit. Advice please on how to deal with this

  22. Tony Q  Says:

    I have a question: I just bought a Valencia Orange tree from a local nursery and have my gardener planted it already. It is about 6 ft to my house in the sideyard. However, the label tag says it is a standard size tree and the tree size is 15-25 ft. Spacing is 15-20 ft. The tree is still small. So it is OK for now. However, my question is whether 6 ft is far enough to my house consider when the tree becomes mature? if not, what should I do? I am concerned that if we don’t leave enough space to the house, when it has grown up, the tree root would hurt my house foundation.

  23. Administrator  Says:

    Mike PEtschen… maybe. It needs warmth and especially sun, in MN you’re pretty far north… Outside of a greenhouse where it’d absolutely get as much sun as nature can provide at your latitude I’m not sure it would fruit. If it is just indoors near a window it probably will not.

  24. Administrator  Says:

    Tony Q, move it. Fruit trees do not get large and are unlikely to harm your foundation (they don’t develop those concrete lifting roots like say an Oak), but 6 feet is still too close to the house. Try 10 feet, and move it now, moving it later will only be harder and stress the tree out more.

  25. Paul Duimstra  Says:

    Why are my oranges turn out dry? We water every day because they are in pots, we bring them in every winter. They are 30yrs old and produce fruit all the time. We don’t have any problem with the lemon trees
