Caring for Flowering Gardenia (Cape Jasmine) Shrubs

Overview

Flowering gardenia (cape jasmine) is a perennial shrub grown for large ornamental flowers, enticing fragrance, and glossy foliage. Blooms late spring to summer with 4-inch white aromatic flowers that attract butterflies. Native to tropical Asia; hardy only in USDA zones 8–11. In cooler areas, grown as houseplants.

Step 1: Light and Temperature

4–6 hours bright sun daily. Maintain 68–74°F day / 60°F night.

Step 2: Humidity Tray

Fill shallow tray with pebbles and water to just below top. Set pot on tray; replenish water as needed.

Step 3: Watering Schedule

Water weekly to prevent complete dry-out. Reduce to every two weeks in winter dormancy. Water soil directly to avoid fungal issues.

Step 4: Monthly Acid Feeding

Feed monthly with acid fertilizer. Water first to prevent root burn. Follow label rates.

Step 5: Post-Bloom Pruning

Prune immediately after flowering ends. Remove overgrown, bare, damaged, or diseased branches with shears.
