First, you need to water the young orange plants in abundance. Water these plants thrice in the first week and twice in the subsequent weeks. After a few weeks, you should water the growing plants when the soil becomes fully dry.
You should weed the ground area around the orange tree. However, do not let mulch grow around it as that brings foot rot disease which is deadly for the growth of an orange tree. If you see any mulch growing, immediately remove it.
While planting an orange tree or after the planting process, you should add mycorrhizal fungi. Mix it to the soil near the root area which will help in producing the required amount of fungus which is good for the growth of an orange tree.
Applying fertiliser in regular intervals is vital in making your orange tree grow well. You should use Ammonium Sulphate and scatter it around the ground where you have planted the orange tree.
One cup of Ammonium Sulphate is sufficient for one time and you should repeat this process every three months in the first year. In the second year, you need to increase the quantity of Ammonium Sulphate from one to two cups.
You should water the orange plant thoroughly after providing fertiliser which is essential to help the Ammonium Sulphate dissolve in the soil around the tree.
To ensure proper development, you should set up clean soil around the trunk of the orange tree especially in cold weather. This helps the tree absorb sunlight which is necessary for its growth.
