Planting and repotting an orange tree
Planting directly in the ground
The orange tree can be planted directly in the ground only in regions where it doesn’t freeze in winter.
Planting in pots
In areas where winters are on the cold side, you must plant your orange tree in a large garden box.
In winter, it should be placed in a very bright room, where the temperature should not drop below 41 to 43°F (5 to 6° C) in winter.
Early spring, you can bring it out for it to spend the rest of the year outdoors.
Repotting an orange tree
When planting or repotting, favor a blend of soil mix and plant-based soil without any chalk, one part each.
Repotting is preferably done in spring, after the fruit harvest or at the end of summer before flowering.

Watering orange trees
Watering of the orange tree is very important, all the more so if it is in a pot, since it tends to dry off much faster.
- Orange trees hate having too much water.
- So watering, although necessary in summer, must not be abundant, but reduced and regular.
- Favor watering in the evening so that water isn’t lost through evaporation so fast.
Pruning and caring for an orange tree
Fruits only grow on new growth, so you must prune at the end of winter, during the month of February or March.
- Eliminate branches that are ingrowing to provide as much light as possible inside. In addition, remove branches that cross over each other, too.
- You can also balance the silhouette to give it a nice shape. Prune lightly.
Producing nice oranges
To produce nice oranges, add citrus-specific fertilizer during the growth phase.
Some orange tree varieties don’t self-pollinate easily. For these, it’s best if you can ensure proper cross-pollination between two compatible varieties.
