How do you care for Micropus brevissimus?
Plant Micropus brevissimus in full sun to partial shade (USDA zones 12a) and water a young shrub every 7–10 days until it is established. It tolerates temperatures of 50–80°F (10–27°C). Fertilize it every 6 months during the growing season.
What Is the Micropus brevissimus?
Micropus brevissimus (Psilocarphus brevissimus) belongs to the Asteraceae family within the Psilocarphus genus. Micropus brevissimus is also known as Psilocarphus globiferus, Psilocarphus globuliferus.
Micropus brevissimus displays a low-growing mat-forming growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Micropus brevissimus produces small white or yellow daisy-like flowers.
Leaf size: approximately 1.5 inches.
How Often Should You Water a Micropus brevissimus?
Water a young or newly planted Micropus brevissimus every 7–10 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.

What Soil Mix Works Best for a Micropus brevissimus?
Well-draining sandy soil mix with added organic matter. Good drainage is essential for Micropus brevissimus to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Micropus brevissimus?
Feed Micropus brevissimus 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.

Where Should You Plant a Micropus brevissimus?
Choose a spot with full sun to partial shade and well-draining sandy soil mix with added organic matter. Avoid low spots where water collects after rain.
Micropus brevissimus 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.
How Far Apart Should You Plant a Micropus brevissimus?
Micropus brevissimus 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 Micropus brevissimus?
Prune Micropus brevissimus 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 Micropus brevissimus in Winter?
Micropus brevissimus 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.
How Do You Propagate a Micropus brevissimus?
Micropus brevissimus can be propagated through seeds. Similar propagation techniques also apply to tall woolly heads plant care, which shares the same genus.
Is the Micropus brevissimus Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Micropus brevissimus, 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.
