How to keep Gardenia Augusta.
Light
A gardenia's ideal light exposure is a consistent blend of sun and shade, with more weight given to shade. It can, however, tolerate full-day sun or remain in complete shade. This flexibility mirrors the varying sunlight conditions of its native habitat. Excessive sun can scorch the leaves, while too little light may hamper growth and flowering.
Temperature
A gardenia native to warm areas prefers temperatures between 59 and 100 ℉ (15 and 38 ℃). For best growth, provide high humidity and keep the soil moist. In winter, protect it from cold drafts and maintain temperatures of 60 to 65 ℉ (16 to 18 ℃).
Fertilizer
The timing of fertilizing Gardenia is crucial. Apply fertilizer in early spring and continue once a month until early summer. Fertilizer promotes attractive blooms and supplies energy during both dormant and active growth stages.
Pot & Repot
When repotting a gardenia, pick a pot 1-2 inches (2.5–5.1 cm) larger that provides ample drainage. Use a well-draining potting mix. Repot in spring or fall, ensuring the root ball sits slightly lower than the rim of the flower pot. Water thoroughly after repotting and place it in a warm spot with indirect sunlight.
