Ideal Soil Mix and pH for Gardenias

Gardenia Soil Requirements

Gardenias demand well-drained, acidic soil rich in organic matter.

Recommended Potting Mix

• Equal parts high-quality potting mix and compost.
• Maintain acidity with a product like Miracid (or sulfur/iron supplements).
• Ensure containers have excellent drainage.

Ongoing Care

Test soil pH periodically (target 5.0–6.0). Fertilize with acid-loving plant food. Avoid lime. Keep consistently moist but not soggy. Mulch with pine bark or needles to conserve moisture and acidity.
