How do you care for Anthoceros tenuissimus?
Plant Anthoceros tenuissimus in filtered sunlight (USDA zones 13a) and water a young shrub every 3–5 days until it is established. It tolerates temperatures of 60–75°F (16–24°C).
What Is the Anthoceros tenuissimus?
Anthoceros tenuissimus (Anthoceros tenuissimus) belongs to the Anthocerotaceae family within the Anthoceros genus.
Anthoceros tenuissimus displays a low rosette, spreading mat growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Anthoceros tenuissimus produces non-flowering.
Leaf size: approximately 1 inches.
How Often Should You Water a Anthoceros tenuissimus?
Water a young or newly planted Anthoceros tenuissimus 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.

Until established; then in dry spells
What Light Does the Anthoceros tenuissimus Need?
Anthoceros tenuissimus thrives in filtered sunlight. Avoid placing Anthoceros tenuissimus in direct, harsh sunlight for extended periods, as this can scorch the foliage.
Light Requirement
Filtered sunlight
What Temperature and Humidity Does the Anthoceros tenuissimus Prefer?
Anthoceros tenuissimus tolerates temperatures of 60–75°F. Anthoceros tenuissimus prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

What Soil Mix Works Best for a Anthoceros tenuissimus?
Well-draining loamy soil with high organic content. Good drainage is essential for Anthoceros tenuissimus to prevent waterlogging, which leads to root rot and fungal issues.
Where Should You Plant a Anthoceros tenuissimus?
Choose a spot with filtered sunlight and well-draining loamy soil with high organic content. Avoid low spots where water collects after rain.
Anthoceros tenuissimus is suited to USDA Zone 13a.
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.
How Far Apart Should You Plant a Anthoceros tenuissimus?
Anthoceros tenuissimus 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.

How Do You Prune a Anthoceros tenuissimus?
Prune Anthoceros tenuissimus 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.
How Do You Care for a Anthoceros tenuissimus in Winter?
Anthoceros tenuissimus is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.
How Do You Propagate a Anthoceros tenuissimus?
Anthoceros tenuissimus can be propagated through spores. Similar propagation techniques also apply to anthoceros adscendens plant care, which shares the same genus.
Is the Anthoceros tenuissimus Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Anthoceros tenuissimus, so we can't confirm whether it is safe for cats and dogs. Keep pets from chewing it as a precaution.
This is a general caution, not veterinary or medical advice. If your pet ate a plant, contact your vet or animal poison control.

What Pests and Diseases Affect the Anthoceros tenuissimus?
Anthoceros tenuissimus is susceptible to not commonly affected by pests. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

What USDA Hardiness Zone Does the Anthoceros tenuissimus Need?
Anthoceros tenuissimus grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. In cooler regions, grow Anthoceros tenuissimus as a houseplant or bring it indoors before the first frost.
