Featuring glossy green, aromatic broadleaf evergreen foliage, and incredibly fragrant white flowers, the light orange rinds and pinkish insides are wonderfully flavorful and juicy!

The Cara Cara Orange is sweet and a fan favorite, but also a nutritional powerhouse, with plenty of Vitamin C, Vitamin A, folate, and lycopene (which gives them their fantastic colored flesh!).

The Cara Cara Sweet Orange Tree is an easy Fruit Tree to grow, so you can enjoy this healthy fruit from your own yard throughout USDA planting zones 9 - 10.

Not only is it adapted to any landscape wherever Citrus grows well, but the Cara Sweet Orange can also grow up to 8-12 feet tall and 3-4 feet wide when not pruned. However, for easier picking, container gardening, and pest control, the Cara Cara Orange is easily kept pruned at 6 to 8 feet.

Read on to learn about how to grow these fantastic fruit trees and their close cousins successfully!

#ProPlantTips for Growing Cara Cara & Orange Trees

Standard Citrus care is applied to the Cara Cara Orange!

Outside-grown Citrus needs a location where your Citrus Tree has a full day’s worth of sun. The more sun, the more flowers, and therefore, more fruit!

Citrus also grows best in slightly acidic soil. You can have a simple soil test done to determine the health of your soil. But usually, any fast-draining enriched soil with a 3-4 inch deep layer of pine bark mulch over the soil surface will work for your tree just fine!

Fertilizing is required for container-grown Citrus plants and helps support your in-ground plants as well. An organic acid fertilizer applied 3-4 times a year is recommended for your Orange tree.

Don’t Overwater Your Cara Cara

Orange Watering Can

Watering timing and amount are always critical for Citrus trees, both in the ground or in a container. Your Citrus likes to be on the dry side. Overwatering your Cara Cara can result in common problems such as yellowing leaves, leaf drop, and lack of vigor.

This is of particular concern for both indoor and outdoor growers. The Citrus tree’s water requirements decrease dramatically once it is brought indoors and during the winter when Citrus do not grow as much.

Become familiar with your winter water needs while indoors. Check before watering to determine if your plant needs water by using the Finger Test.

Ensure your potted Orange Tree has very good drainage holes so the roots do not sit in water ever. Root rot is the death of a Citrus Tree!

Grow Cara Cara & Oranges Indoors As Container Plants

The Cara Cara Orange is also a perfect container tree, giving you a great patio specimen or an amazing accent container plant in the garden.

Container growing allows the Cara Cara Orange to be grown in the more marginal Citrus areas, and where in-ground locations are not the best, either due to poor soil or poor drainage. This way, you can move your Cara Cara to a protected location or cover your plant to help protect against the occasional winter cold.

The Cara Cara may also be the best Sweet Orange variety for extreme cold climates. This is where indoor-to-outdoor growing is required. The early ripening Cara Cara will benefit from being kept outdoors until the temperatures drop into the high to mid-40s, and then needs to be gradually brought indoors. That will allow the fruit to ripen as much as possible outdoors, benefiting from the extra sunlight exposure.

Protecting Container Citrus From Cold

Although famous for growing in warmer regions, Orange Trees can also thrive in colder areas as long as the tree is brought indoors prior to the first frost of winter.

If you're growing these tropical trees in the ground in the lowest of their favored growing zones, they need to be planted in a sheltered spot to avoid the worst of the chill. If a spot like that is unavailable, then you are better off planting in a large, deep container.

In borderline growing zones, begin slowly acclimating your tree indoors or into a protected location, eventually moving your tree inside in bright indirect sun for the winter if the temperatures in your area ever dip below the 40°F range. In spring, reverse this process and begin acclimating your tree to again be back out in the full sun all summer.

This gradual acclimation indoors and out each year significantly reduces stress and leaf drop. You can keep your trees happy indoors by ensuring they have adequate humidity, bright yet indirect sunlight, and close monitoring of their soil moisture.

Frequently Asked Questions

What are the ideal growing conditions and sunlight requirements for a Cara Cara Navel Orange tree?

Cara Cara Navel Orange trees thrive in USDA zones 9-10 and require full sun exposure throughout the day for optimal flower and fruit production. They prefer slightly acidic soil and will naturally grow 8-12 feet tall and 3-4 feet wide, though you can easily prune them to a more manageable 6-8 feet for easier harvesting. Plant your tree in the sunniest location available and consider having a soil test done to ensure proper pH levels for the best growing conditions.

How much space should I leave between multiple Cara Cara Orange trees when planting?

When planting multiple Cara Cara Orange trees, space them 8-10 feet apart to allow for their mature spread of 3-4 feet wide while providing adequate air circulation. If you plan to keep them pruned to the manageable 6-8 foot height, you can reduce spacing to 6-8 feet between trees. In USDA zones 9-10 where these trees thrive, proper spacing prevents overcrowding and ensures each tree receives the full sun exposure needed for maximum fruit production. Plan your layout before planting to accommodate both current size and future growth.

What is the best way to plant a Cara Cara Orange tree, including hole preparation and backfilling?

Plant your Cara Cara Orange tree in USDA zones 9-10 by digging a hole twice as wide as the root ball but no deeper than the container height. Position the tree so the root flare sits at or slightly above ground level, then backfill with the original soil mixed with compost to improve drainage in the slightly acidic conditions citrus prefers. Choose a full sun location and plant in spring after the last frost for best establishment. Water thoroughly after planting and maintain consistent moisture during the first growing season.

How often should I water my Cara Cara Orange tree, and how do I avoid root rot?

Water your Cara Cara Orange tree deeply but infrequently, allowing the top 2-3 inches of soil to dry between waterings. In USDA zones 9-10, this typically means watering every 7-10 days during growing season and less frequently in winter. Ensure your tree has well-draining, slightly acidic soil and avoid letting it sit in standing water. Check soil moisture with your finger before watering and reduce frequency during cooler months when the tree's water needs decrease.

When and how should I fertilize a Cara Cara Orange tree for optimal growth and fruit production?

Fertilize your Cara Cara Orange tree monthly during the growing season (spring through early fall) with a citrus-specific fertilizer that contains micronutrients like iron, zinc, and manganese. In USDA zones 9-10, apply fertilizer from March through October, reducing frequency to every 6-8 weeks during cooler months. Use a balanced citrus fertilizer at the rate specified on the package, typically 1-2 pounds per mature tree annually, divided into multiple applications. Water thoroughly after fertilizing and maintain slightly acidic soil (pH 6.0-6.5) for optimal nutrient uptake.
