What Is the Coelospermum decipiens?
Coelospermum decipiens (Coelospermum decipiens) belongs to the Rubiaceae family within the Coelospermum genus. Coelospermum decipiens is native to tropical evergreen forests.
Coelospermum decipiens displays a compact, mounding shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 3 ft. Coelospermum decipiens produces small, fragrant white flowers in clusters.
Leaf size: approximately 4 inches.
How Often Should You Water a Coelospermum decipiens?
Water a young or newly planted Coelospermum decipiens 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 Coelospermum decipiens?
Well-draining, acidic soil mix with added organic matter like peat moss. Good drainage is essential for Coelospermum decipiens to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Coelospermum decipiens?
Feed Coelospermum decipiens 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 Coelospermum decipiens?
Choose a spot with bright indirect light and well-draining, acidic soil mix with added organic matter like peat moss. Avoid low spots where water collects after rain.
Coelospermum decipiens 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.
How Far Apart Should You Plant a Coelospermum decipiens?
Coelospermum decipiens can spread to about 3 ft (0.9 m) and reach about 3 ft (1 m) tall. Space plants about 3 ft (0.9 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 Coelospermum decipiens?
Prune Coelospermum decipiens 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 Coelospermum decipiens in Winter?
Coelospermum decipiens 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 Coelospermum decipiens?
Coelospermum decipiens can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to coelospermum reticulatum plant care, which shares the same genus.
Is the Coelospermum decipiens Toxic to Pets and Children?
