Fertilizing Orange Trees: When, How & Which Fertilizer

The orange tree derives from the different citrus species in the Rutaceae family. They are the largest group of citrus around the world.

When oranges are mentioned, it is a reminder between the winter days and a cool summer juice. To be honest, in my personal opinion is the smoothness that creates in the skin and increasing body collagen to fight gems. Since skin is the biggest organ, take good care.

Anyway, back to the fertilization. Oranges are just like all the citrus family, the tree needs feralization to grow, actually, they are starving but poor things don’t know how to ask.

With proper fertilization, you can achieve a fruitful season. Let’s find out more.

When to fertilize Orange Trees?

The orange tree asks for 1 or 2 months of fertilizing throughout the growing time which is Spring and Summer). During the dormant period, the orange tree still needs fertilization for about 2-3 months.

As the time passes and the tree gets very old, you are allowed to skip the fertilization during the dormant period in the Fall and Winter months. 

Citrus families in general including orange trees are nutrient starving freaks and in case of under-fertilization, they won’t provide fruit.  

Bear in mind that the orange tree needs more food during the growing season than in maturity. To decide whether you should or shouldn’t fertilize, checking the soil and the physical appearance will answer the question. Later on, I will be mentioning some visual signs to identify if the orange needs fertilization.

How To Fertilize Orange Trees?

The fertilization process in the orange tree is easy and has 2 methods. You can choose to fertilize from the ground or through the leaves, no worries, the leaves will be fine.

Apply the balanced fertilizer for about 1/2 pounds in the first year of the orange tree. Keep applying every 6 weeks till October. In the second year of the orange tree, 1 pound of fertilizer in a single tree during the growing season is ideal (every 7 weeks until October).

If you want the best result to follow these rules.

  • For young orange trees fertilize every 3 weeks with a balanced NPK ratio.
  • Never let the fertilizer be in contact with the trunk. Start with 1/2 cup in 3 inches square feet and increase gradually as the size gets larger.
  • The orange tree in a container needs consistent watering and fertilization with 2-1-1 for 1 or 2 inches deep in the soil.
  • Fertilizing in Fall and winter will protect against weather threats.
  • For 5+ orange trees, fertilize 10 feet beyond the canopy. The best time would be February, April, and September with NPK 8-8-8 ratio.
  • Mulch the area to avoid weed growth and make the fertilization more effective.

Best Fertilizers For Orange Trees

Pro Tip: Invest in the citrus tree fertilizer as they are picky, plus be highly careful with excessive watering.

1. EcoScraps Organic Gardening

As you can see from the picture of the bag. It is specific for the healthy and happy growth of the citrus orange tree as well as fruiting trees, palms, grapes, and flowering vines.

The NPK is a 5-2-3 ratio and the ingredients inside have recycled leftovers from all pieces of the food life cycle. That means the wasted parts don’t go to landfills.

Eco Scraps is very easy to use and is organic, so you don’t have to worry about children and pets. It would be unfair not to share that dogs especially will love the smell and is pretty much capable to reach the tree. It won’t harm by any means, but the stomachache will be present.

The downside of the Dr, Earth fertilizer is growing too many leaves than necessary. The manufacturer intended the full growth and be extra careful with application because a small mistake can make only leaf growth, not fruit.

How Long it Takes the Orange Tree to Grow?

It takes 3-5 years for an orange tree to become fully established. When the tree produces fruit, after 7-8 months it starts the maturity process.

How to Take Care of Orange Tree? 

The watering requirements for citrus plants are pretty similar to those for other indoor plants. They dislike being overwatered, so in the winter, let the soil dry up in between waterings. In contrast, they require more frequent watering throughout the summer, perhaps once or twice each week. 

Tell me the Best Orange Tree Types to Plant.

I would highly recommend planting these 4 types of orange trees. They are Washington navel, Valencia, Moro blood orange, and honey balls ornge. Thank me later. 

A Brief Recap

The orange tree is a part of the citrus tree and they are known to be heavy feeders. Always follow the instructions of the manufacturer and for safety’s sake pick organic instead of chemical fertilizers.

However, that is a personal opinion and doesn’t affect the plant’s growth. Organic isn’t necessarily better, it depends on the chosen product. 

I strongly recommend planting not an ordinary tree but something different like honey balls or moro blood orange. The choice is yours.
