Chrysosplenium tosaense Plant Care

Chrysosplenium tosaense (Chrysosplenium tosaense) belongs to the Saxifragaceae family within the Chrysosplenium genus. Chrysosplenium tosaense is native to Japan.

Chrysosplenium tosaense displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Chrysosplenium tosaense produces small, inconspicuous greenish-yellow flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Chrysosplenium tosaense every 3–5 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Chrysosplenium tosaense thrives in partial to full shade. The optimal light range is 50–200 lux. Avoid placing Chrysosplenium tosaense in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Chrysosplenium tosaense tolerates temperatures of 50–75°F. Chrysosplenium tosaense prefers humidity levels of 40–70%.

Moist, well-draining soil with high organic content. Good drainage is essential for Chrysosplenium tosaense to prevent waterlogging, which leads to root rot and fungal issues.

Feed Chrysosplenium tosaense every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with partial to full shade and moist, well-draining soil with high organic content. Avoid low spots where water collects after rain.

Chrysosplenium tosaense is suited to USDA Zone 12a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Chrysosplenium tosaense can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Chrysosplenium tosaense while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Chrysosplenium tosaense is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Chrysosplenium tosaense can be propagated through division, seeds. Similar propagation techniques also apply to american golden saxifrage plant care, which shares the same genus.

Chrysosplenium tosaense grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Chrysosplenium tosaense is native to Japan. In cooler regions, grow Chrysosplenium tosaense as a houseplant or bring it indoors before the first frost.
