None Plant Care

None (Mitragyna stipulosa) belongs to the Rubiaceae family within the Mitragyna genus. None is native to Angola, Cameroon, Central African Republic, the Republic of the Congo, the Democratic Republic of the Congo, Gabon, Gambia, Ghana, Guinea, Nigeria, Senegal, Sierra Leone, Sudan, Uganda, and Zambia.

None displays a tall, upright tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. None produces small, fragrant white flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted None 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.

None thrives in partial shade to full sun.

Mitragyna stipulosa tolerates temperatures of 65–85°F. None prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with high organic content. Good drainage is essential for None to prevent waterlogging, which leads to root rot and fungal issues.

Feed None 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.

Choose a spot with partial shade to full sun and rich, well-draining soil with high organic content. Avoid low spots where water collects after rain.

None is suited to USDA Zone 10b – 12b.

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.

None can spread to about 15 ft (4.6 m) and reach about 30 ft (9 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune None 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.

None is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

None can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to mitragyna diversifolia plant care, which shares the same genus.

None is susceptible to aphids, scale insects, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

None grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. None is native to Angola, Cameroon, Central African Republic, the Republic of the Congo, the Democratic Republic of the Congo, Gabon, Gambia, Ghana, Guinea, Nigeria, Senegal, Sierra Leone, Sudan, Uganda, and Zambia. In cooler regions, grow None as a houseplant or bring it indoors before the first frost.
