How do you care for Tree Phylica?
Plant Tree Phylica in full sun to partial shade (USDA zones 12a) and water a young shrub every 7–14 days until it is established. It tolerates temperatures of 50–80°F (10–27°C). Fertilize it every 6 months during the growing season.
What Is the Tree Phylica?
Tree Phylica (Phylica arborea) belongs to the Rhamnaceae family within the Phylica genus.
Tree Phylica displays a compact, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Tree Phylica produces small, fragrant white or pink flowers in clusters.
Leaf size: approximately 2 inches.
How Often Should You Water a Tree Phylica?
Water a young or newly planted Tree Phylica every 7–14 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 Tree Phylica?
Well-draining sandy soil mix with added organic matter for moisture retention. Good drainage is essential for Tree Phylica to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Tree Phylica?
Feed Tree Phylica 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.
Fertilizing

Where Should You Plant a Tree Phylica?
Choose a spot with full sun to partial shade and well-draining sandy soil mix with added organic matter for moisture retention. Avoid low spots where water collects after rain.
Tree Phylica 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 Tree Phylica?
Tree Phylica 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.

How Do You Prune a Tree Phylica?
Prune Tree Phylica 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 Tree Phylica in Winter?
Tree Phylica 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 Tree Phylica?
Tree Phylica can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to polium-leaved phylica plant care, which shares the same genus.
Is the Tree Phylica Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Tree Phylica, 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 Tree Phylica?
Tree Phylica 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 Tree Phylica Need?
Tree Phylica grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. In cooler regions, grow Tree Phylica as a houseplant or bring it indoors before the first frost.
