Persimmon Bonsai Care guidelines
Persimmon bonsai require plenty of sunlight to thrive, ideally 5-6 hours per day. The more sunlight they receive, the stronger and healthier the tree will be. In general, these trees prefer full sun, especially in the spring and summer when they are actively growing. However, during the hottest months, some afternoon shade can prevent the tree from getting sunburned. Persimmon bonsai are best kept outdoors, as they require a period of dormancy in the winter to stay healthy. If you live in a mild climate (USDA Zones 7-9), you can grow your persimmon bonsai outside year-round. Persimmon bonsai can withstand temperatures as low as 20°F (-6°C), though temperatures below this may require extra care, such as insulation or moving the tree into a frost-free area during winter..
Persimmons require regular watering, especially during the growing season (spring through fall). The soil should be kept moist but never wet for a long period. It’s important to check the moisture level of the soil regularly. A good rule of thumb is to water when the top inch of soil feels dry to the touch. During the winter dormancy period, watering can be reduced, but the soil should not dry out completely. Water your persimmon thoroughly, ensuring that the water drains out of the bottom of the pot.

Watch Like most bonsai trees, persimmon bonsai benefit from regular feeding to promote healthy growth. Use a balanced, slow-release fertilizer with an equal NPK ratio during the growing season. You can also use a liquid fertilizer diluted to half-strength every two weeks. Start fertilizing in early spring as new growth begins and continue feeding throughout the summer. Reduce or stop fertilizing in late fall and winter when the tree is dormant. Over-fertilization can lead to weak, leggy growth.
Regular pruning is necessary to maintain the desired shape of your persimmon bonsai. In early spring, remove any dead or damaged branches, and trim back excessively long growth. An ideal time to prune is when the tree sheds its leaves and fruits, so you can see the branch structure well. Continue reading about pruning Bonsai trees. The Persimmon responds well to wiring, which can be used to shape branches and trunks. Use bonsai wire carefully to bend branches into the desired shape, but be cautious not to damage the bark. The wire should be removed before it begins to cut into the tree’s tissue, usually after a few months
Repotting should be done every 2-3 years, depending on the age and size of the tree. When repotting, trim the roots to encourage healthy, compact growth, and replace the soil mix to ensure that it remains fresh and nutrient-rich. Repot in early spring, before the tree begins its active growing phase. Kaki bonsai need well-draining soil that retains moisture but doesn’t become soggy. We recommend our standard mix of Akadama, pumice, and lava rock in equal proportions. This mixture will provide good aeration and drainage while retaining enough moisture for the roots.

The Persimmon, or Kaki Bonsai, can be propagated using cuttings.
Persimmon are relatively resistant to pests, but they can still attract occasional insects such as aphids, spider mites, and scale. Regularly inspect the leaves and branches for any signs of pests. If pests are found, remove them by gently washing the affected areas with a soft brush or spraying the tree with insecticidal soap. Overwatering and poor drainage can lead to root rot and fungal infections, so it's essential to ensure proper soil conditions. If the tree’s leaves turn yellow or drop prematurely, this could be a sign of a fungal problem or improper watering. Always allow the soil to dry slightly between waterings, and avoid letting the tree sit in standing water. For more detailed information on these techniques, check out our Bonsai tree care section.
Persimmon Bonsai, the Diospyros virginiana
General information about the Persimmon Bonsai tree
Persimmon bonsai are typically grown from the Diospyros species, with the most common being Diospyros virginiana (the American persimmon). Another variety is the Diospyros kaki bonsai (the Japanese persimmon). These trees are known for their smooth, dark green leaves that turn golden yellow or red in the fall, as well as their striking fruit. When grown as bonsai, persimmons often feature a graceful, slightly twisted trunk and a compact, symmetrical canopy. Persimmons are deciduous, meaning they lose their leaves in winter, so they go into a dormant period.
One of the joys of growing persimmon bonsai is the opportunity to see the tree produce fruit. Persimmons can start fruiting when they are around 5-7 years old, depending on the species and growing conditions. However, for bonsai purposes, it’s important to manage the fruit to ensure the health and beauty of the tree. If your persimmon bonsai produces too many fruit, it can cause the tree to become stressed. To ensure that the remaining fruit develops properly, thin out the fruit by removing excess ones during early summer. This allows the remaining fruit to grow larger and more vibrant.
