Justicia tocantina Plant Care

Justicia tocantina (Justicia tocantina) belongs to the Acanthaceae family within the Justicia genus. Justicia tocantina is native to Bolivia, west-central and southeastern Brazil, and Paraguay, including the Cerrado ecoregion of Brazil.

Justicia tocantina displays an upright, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Justicia tocantina produces colorful tubular flowers in various shades.

Leaf size: approximately 6 inches.

Water a young or newly planted Justicia tocantina 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.

Justicia tocantina thrives in bright indirect light. Avoid placing Justicia tocantina in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Justicia tocantina tolerates temperatures of 65–80°F. Justicia tocantina prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, fertile soil with added organic matter like compost or peat moss. Good drainage is essential for Justicia tocantina to prevent waterlogging, which leads to root rot and fungal issues.

Feed Justicia tocantina every 4 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 bright indirect light and well-draining, fertile soil with added organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Justicia tocantina is suited to USDA Zone 13b.

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.

Justicia tocantina can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Justicia tocantina 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.

Justicia tocantina 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.

Justicia tocantina can be propagated through stem cuttings, division, seeds. Similar propagation techniques also apply to shrimp plant plant care, which shares the same genus.

Justicia tocantina is susceptible to aphids, spider mites, whiteflies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Justicia tocantina grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Justicia tocantina is native to Bolivia, west-central and southeastern Brazil, and Paraguay, including the Cerrado ecoregion of Brazil. In cooler regions, grow Justicia tocantina as a houseplant or bring it indoors before the first frost.
