How do you plant an orange tree?

There are 3 ways to plant an orange tree.

1. Grafting or budding orange tree

Grafting is a horticultural process wherein two plants are joined together to grow as one. Scion – which is the upper part of the plant – is attached to the lower portion of the plant known as rootstock. Horticulturists use this process when it is impossible to grow a plant through seeds.

Budding, on the other hand, is a form of grafting best suited for citrus trees like orange. You can do this if you already have orange trees in your backyard and you want to plant more trees. Or if you have a neighbor who is willing to give you scion and rootstock for budding. Some local nurseries might be able to help you graft materials as well.

  • Select a healthy orange tree that you wish to cultivate.
  • Prepare the scion and rootstock. Remove any leaves or torn on the branch.
  • Using a knife, make a one-inch vertical cut on the rootstock and at the bottom of the cut, make a horizontal cut. Try to avoid cutting the entire branch. This should create an inverted “T” on the rootstock.
  • Cut a one-inch bark from a budded twig or scion.
  • Insert the bark in the rootstock “T” cut.
  • Wrap the graft for 30 days.

Using the seed is the traditional way of planting orange trees. However, keep in mind that it takes years to see the tree grows if you choose to start from the beginning. Success rate of planting orange tree is also lower if you use seeds and especially if you are a beginner. It is more challenging to grow trees from seeds as it is more susceptible to diseases. Also, even if the seeds might come from a good orange fruit, it doesn’t guarantee that it will produce the same result.

  • Buy healthy orange fruits in the supermarket. Make sure the orange fruits are not seedless.
  • Cut the orange carefully and avoid cutting the seeds. Select the undamaged seeds once you’re done.
  • Wash the seeds to remove any fungus or mold spores. Then soak the seeds in the water for 24 hours. Do not soak it longer than 24 hours.
  • Drain the water and transfer it to a prepared pot or containers.
  • Make sure the pot has good drainage holes and you put it in a place where it can get a constant supply of sunshine.
  • Water the seeds once to twice a week or once the soil starts to become dry.

3. Buying a tree from local nurseries

This is probably the easiest way to grow an orange tree. If you are not confident to do grafting or use seeds, then buying a tree from local nurseries is a good option. However, this doesn’t mean that the tree will just produce fruits on its own. An aftercare still remains important for your orange trees.

  • Citrus trees are not a fan of overwatering or underwatering. It is important to water the orange trees once or twice a week. Keep in mind that the goal is to preserve the soil from drying. So, adjust your watering schedule accordingly
  • The orange tree is sensitive to cold.  Try to place them where it can get sunlight for at least 8 hours. Keep them indoor if the temperature is colder.
  • Add fertilizers as needed.
