Planting instructions
Plant Frost Proof Gardenia in a location with well-draining, slightly acidic soil and full sun to partial shade. Dig a hole approximately twice as wide as the rootball and no deeper than the rootball itself. Position the top of the rootball level with or slightly above the surrounding soil, backfill with native soil, water deeply after planting, and apply mulch around the base while keeping it a few inches away from the stems.
Watering & sunlight
Water when the top 2–3 inches of soil begin to dry. Approximately once or twice per week during establishment, then as needed to maintain evenly moist soil once established. Frost Proof Gardenia prefers consistently moist, well-draining soil but should not remain overly wet. Watering frequency may vary based on climate, soil type, rainfall, and establishment phase.

Frost Proof Gardenia grows best in full sun to partial shade. In hotter climates, afternoon shade helps protect the foliage and encourages longer-lasting blooms.
Care guide

PRUNING:
Prune immediately after flowering has finished to maintain shape and encourage healthy branching. Avoid heavy pruning later in the season, as flower buds for the following year develop on older growth.

FERTILIZING:
Feed with a fertilizer formulated for acid-loving plants in spring and again in early summer if desired. Avoid fertilizing for the first 2–3 months after delivery to allow the plant to adjust and establish. Avoid overfertilizing, which can reduce flowering and encourage excessive foliage growth.

WINTER PROTECTION:
Frost Proof Gardenia is more cold hardy than many gardenia varieties but may benefit from mulch around the root zone during severe winter weather. Young plants may appreciate additional protection during unusually hard freezes.
