How to care for gardenia

Gardenia needs bright indirect light, an acidic mix, and stable warmth and humidity. Keep the medium evenly watered, then reduce watering only somewhat in winter.

Find a bright, steady position

Light and temperature

Use bright indirect light and avoid hot direct sun. Partial shade can work when the plant still receives strong ambient light, so shade is not the same as a low-light flowering position.

Keep gardenia warm, humid and stable: RHS gives about 21–24°C by day, 15–18°C at night and roughly 16°C in winter. Protect it from drafts and dry air.

Check the mix, drainage and pot

Watering, drainage and repotting

Keep the medium evenly watered but not saturated during active growth. Reduce watering somewhat in winter without letting the root ball become very dry, and consider rainwater where tap water is hard or alkaline.

Use peat-free acidic ericaceous compost. Repot each spring only one pot size larger, or top-dress when a larger pot is not practical.

Feed only during active growth

Fertilizer and active growth

Use a high-nitrogen liquid feed weekly in spring and summer. In winter, RHS gives a balanced feed with trace elements every five to six weeks. Use the product directions for concentration.

Check the visible signs before changing care

Common problems

Common Visible Problems

Yellow leaves can be associated with excess water or iron deficiency, while browning can follow insufficient water. Poor light or cold can reduce growth and flowering, and dry air or fluctuations can cause bud drop. Inspect for mites, mealybugs, scale and aphids.
