All About the Kishu Mandarin Tree

3 minute read

The Kishu mandarin tree grows mandarin fruit that is very small with a thin peel. Kishu mandarins are prized for their exceptionally sweet and juicy flavor. They are known for being one of the sweetest citrus fruits, with a delightful balance of sweetness and acidity. The fruit has a thin, easy-to-peel skin and is typically seedless, making it a popular choice for snacking and fresh eating.

Kishu mandarins usually ripen in the late fall or early winter, typically between November and January. The exact ripening time may vary depending on the climate and growing conditions of your region.

The Kishu mandarin tree is known for their cold hardiness, making them suitable for cultivation in various climates. They are cold-hardy down to around 32 degrees Fahrenheit. However, they thrive best in warmer regions. The trees are typically small and compact, which makes them a good choice for home gardeners with limited space.

Here are some tips on growing a Kishu Semi-Dwarf Mandarin Tree at home:

1. Selecting the Right Pot: Choose a container with very good drainage. A 10-14” pot is typically suitable for a young tree. Pots with attached saucers are not recommended, as they can keep the roots wet for too long. 

2. Soil Mix: Use a well-draining, chunky potting mix, such as our Primo potting mix. Citrus trees prefer slightly acidic soil. 

3. Planting in the ground: For in-ground planting, plant the tree in a prepared area about 3x the diameter of the pot, and as deep as possible. That soil should be well-draining and loose, allowing for root growth. To plant your tree, dig a hole twice the size of the rootball. Plant at the same depth as the pot, keeping the crown of the roots just above the soil line. Water thoroughly after planting.

4. Location: Place the potted tree in a location with plenty of sunlight, preferably south facing. Kishu mandarins require at least 6-8 hours of direct sunlight per day.

5. Watering: Keep the soil consistently moist but not waterlogged. Water when the top inch of soil is dry. Be sure to allow excess water to drain from the pot. 

6. Fertilizing: Use a balanced citrus fertilizer, such as G&B Organics Citrus and Fruit Tree Fertilizer or Romeo Fertilizer according to the package instructions, typically every month during the growing season (spring and summer). Reduce or stop fertilizing in late fall and winter.

7. Pruning: In the spring, prune the tree as needed to maintain its shape and remove dead or damaged branches. Throughout the year, you may remove dead or diseased branches if necessary. (Click here to read about pruning your citrus tree)

8. Protection from Cold: If you live in a region with cold winters, be prepared to protect your potted Kishu mandarin from freezing temperatures, as it is not frost tolerant. You can bring it indoors for longer periods  or cover it with frost cloth during short cold spells. (Click here to read about Overwintering Your Citrus Trees)

9. Harvesting: Kishu mandarins can be harvested once they turn a bright orange color. This is in the early winter in most regions. They should be easy to peel, completely orange, and, upon tasting, their sweet flavor is a good indicator of ripeness.

Growing citrus trees is not difficult, but it does require your regular attention and care. Provide it with everything that it needs, and you can successfully grow a Kishu mandarin tree in a pot and enjoy the delicious, sweet fruit it produces for many years to come.
