Brunfelsia grandiflora tolerates temperatures of 60–80°F. Large Flowered Brunfelsia prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, fertile soil with added compost for Brunfelsia. Good drainage is essential for Large Flowered Brunfelsia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Large Flowered Brunfelsia 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.

Prune Large Flowered Brunfelsia while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.
