Fortunella obovata Fukushu is a naturally small tree with a spreading habit that makes it an attractive ornamental shrub. The leaves are broader and fruit larger than other kumquat species. At 1 1/2 inches long, the oval fruit boasts thin, sweet, edible rind with tart, acidic flesh and few seeds. It's an especially hardy variety that can withstand temperatures as low as 28°F without protection. When planted in the ground, Fukushu will reach 6-10 feet tall, shorter as a container plant. Its summer blossoms are exquisitely fragrant with fruit ripening in winter.

Our citrus trees are 2-3 years old, well developed and branched with large, healthy root systems. Their trunk diameter ranges 1/2-3/4 inches, above-ground height is over 2 feet, and foliage canopy more than 1 foot in diameter. At this stage of development, they are mature enough to produce fruit. We have selected these special varieties for their vigor, beauty, productivity, and practical utility. Grow in full sun outdoors during warm months. In areas with cold winters, bring indoors and locate in a south facing, sunny window during frosty months. All of our citrus are well suited for cultivation indoors as houseplants. Plants are shipped in 3 gallon pots.
Water thoroughly when soil is dry — test soil moisture with your finger or soil moisture meter. Do not over water (water too frequently or allow the plants to stand in water)! Use citrus fertilizer during the growing season, and less in winter months when days are shorter.
Make sure the soil around the roots stays evenly moist for several weeks after planting. During the first growing season don't let the soil dry out. Periodic deep waterings during the growing season will help your tree grow strong and be less susceptible to drought. Be careful to keep the soil from becoming soggy. A layer of mulch around the trunk of the tree will protect the roots, suppress competitive weeds and conserve water. Avoid piling the mulch up against the base of the plant; leave an inch or so of space around the trunk clear of mulch. To encourage the tree to become established, remove any blossoms that may appear during the first season. During the first dormant season, select 3 strong limbs that are between 2-4 feet off the ground, and remove all but these branches. This will be the foundation framework for the tree. To prune during subsequent dormant seasons, cut damaged, weak or dead limbs, and shape tree as needed.
Size at Maturity
3-6 feet tall when container grown. 6-15 feet tall in the ground. However, trees can be pruned to any shape or height.
Our citrus is self-fertile, but will require hand-pollination when it is indoors. Hand pollinate by moving pollen from flower to flower with a small, soft paintbrush or cotton swab.
