How do you care for Lepidium jaredii?
Plant Lepidium jaredii in full sun to partial shade (USDA zones 12a) and water a young shrub every 4–7 days until it is established. It tolerates temperatures of 50–75°F (10–24°C). Fertilize it every 6 months during the growing season.
Where Is the Lepidium jaredii Native To?
What Is the Lepidium jaredii?
Lepidium jaredii (Lepidium jaredii) belongs to the Brassicaceae family within the Lepidium genus. Lepidium jaredii is native to California.
Lepidium jaredii displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Lepidium jaredii produces small white or pink clustered blooms.
Leaf size: approximately 2 inches.
How Often Should You Water a Lepidium jaredii?
Water a young or newly planted Lepidium jaredii every 4–7 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 Lepidium jaredii?
Well-draining sandy loam with added organic matter. Good drainage is essential for Lepidium jaredii to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Lepidium jaredii?
Feed Lepidium jaredii 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 Lepidium jaredii?
Choose a spot with full sun to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.
Lepidium jaredii 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 Lepidium jaredii?
Lepidium jaredii 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 Lepidium jaredii?
Prune Lepidium jaredii 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 Lepidium jaredii in Winter?
Lepidium jaredii 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 Lepidium jaredii?
Lepidium jaredii can be propagated through seeds, division of clumps. Similar propagation techniques also apply to field pepperweed plant care, which shares the same genus.
Is the Lepidium jaredii Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Lepidium jaredii, 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 Lepidium jaredii?
Lepidium jaredii is susceptible to aphids, flea beetles, cabbage worms. 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 Lepidium jaredii Need?
Lepidium jaredii grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Lepidium jaredii is native to California. In cooler regions, grow Lepidium jaredii as a houseplant or bring it indoors before the first frost.
