What Is the Anacua?

Anacua (Ehretia anacua) belongs to the Boraginaceae family within the Ehretia genus. Anacua is native to eastern Mexico and southern Texas in the United States. Anacua is also known as Anaqua, Sugarberry, Knackweed.

Anacua displays a small tree or shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Anacua produces small white or pink tubular flowers in clusters.

Leaf size: approximately 3 inches.

How Often Should You Water a Anacua?

Water a young or newly planted Anacua every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees 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 Anacua?

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Anacua to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Anacua?

Feed Anacua every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Where Should You Plant a Anacua?

Choose a spot with full sun to partial shade and well-draining sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Anacua is suited to USDA Zone 13a.

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

How Far Apart Should You Plant a Anacua?

Anacua can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 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 Anacua?

Prune Anacua 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 tree in one year.

How Do You Care for a Anacua in Winter?

Anacua 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 Anacua?

Anacua can be propagated through seeds, semi-hardwood cuttings. Similar propagation techniques also apply to koda plant care, which shares the same genus.

Is the Anacua Toxic to Pets and Children?

Pet safety not verified

The ASPCA does not list Anacua, 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 Anacua?

Anacua is susceptible to aphids, spider mites, scale insects. 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 Anacua Need?

Anacua grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Anacua is native to eastern Mexico and southern Texas in the United States. In cooler regions, grow Anacua as a houseplant or bring it indoors before the first frost.
