Combining a thin, sweet orange skin with juicy, tangy-sweet flesh, Fukushu kumquats are a favorite for eating out of hand, baking in tarts, making into marmalade or using as a garnish for cocktails. Our kumquat tree arrives ready for transplanting into the ground, a planter, or a decorative container (wooden planter shown not included). A dwarf variety, it will bear fragrant white blossoms in the spring and olive-sized fruit in the winter.

Dimensions & More Info

Additonal Informatoin

  • Tree is approx. 3 years old at time of shipment.
  • Tree arrives fully rooted in a black plastic pot.
  • Please water tree immediately upon arrival.


  • Whether planting in a container or in the ground, plant the tree so the root collar (crown roots) shows above the soil line. The soil line in the pot as you recieved it should remain the soil line after planting. Make sure that soil or mulch is not pushed up against the trunk of the tree.
  • Citrus grows best between 55°F and 85°F. Indoor temperatures averaging 65°F are conducive to growth if light is adequate. Protect from freezing temperatures.

Light Exposure

  • Provide 8 or more hours of direct sunlight per day. If less than 6 hours of natural full sun is provided, supplement with grow lights. An unobstructed window facing south or southwest is ideal.


  • Citrus trees require soil that is moist but never soggy. Watering frequency will vary with soil porosity, tree size, and environmental factors. Do not water if the top of the soil is dry without checking the soil at root level. A simple moisture meter, available at garden supply stores, will read moisture at the root level. This inexpensive tool will allow you to never have to guess about whether or not a plant needs water.


  • Citrus trees feed heavily on nitrogen. Your fertilizer should have more nitrogen (N) than phosphorous (P) or potassium (K). Use at least a 2-1-1 ratio. Miracid Soil Acidifier is a water-soluble product that works well and is a 3-1-1 ratio. In some regions, you may be able to find specialized citrus/avocado fertilizers. In general, buy a good slow-release formula that contains trace minerals like iron, zinc and manganese and apply according to package directions.

  • Rated 1 out of 5 by from Plants don't Survive under the best care Plant arrived, looked healthy, the roots in the wood chips were extremely wet. However, i saw that this is a plant grown from a graft. I wish William Sonoma would mention this. Upon repotting it in 10 gallon pot with well drained soil, the plant experienced tremendous leaf drop while placed in full sun in the next seven days but no growth occurred. Plant was wintered with artificial lighting and temperature control and leaf drop was gradual. I took it out this spring and the remaining leaves dropped and plant died oozing a lot of sap around stem nodes and where the graft is. The plant was well looked after, Fertilized with the right NPK proportions along with trace minerals which are essential too. I have another citrus which I propogated from a seed which about 5 years old and thriving.

    Rated 1 out of 5 by from Sent diseased tree I contacted the vendor for this Kumquat and sent pictures. I was told to throw it away because it was too hard to treat and send them my shipping information and they would replace it. NO THANKS! I sent them a email back stating that Willams-Sonoma wanted it back and I wanted a refund. They had to have seen this when they shipped it. I sure did when I opened the box. This costs way too much for them to send out plants like this. Buyer beware!

    Rated 5 out of 5 by from new kumquat to evaluate This is a new cultivar for me to grow. The plant arrived in excellent condition. I like the idea of it being bare-root . It allows me to control the potting mix used in the container. Frequently the potting mixes of the container grown citrus, available in local nurseries, are extremely dense and only suitable for direct planting in a garden. My intended use allows me to eventually transplant the dwarf tree into a 10 or 15 gallon pot. The tree will be displayed on a patio so its fruit can be easily picked and immediately consumed. The plant is already sending out new shoots after three weeks. I would highly recommend the nursery grower and plan on acquiring several more citrus cultivars in the future.
