Gardenias are loved for their creamy white flowers, glossy leaves and unforgettable scent. While they can be a little fussy, growing them indoors means you get to enjoy their perfume no matter the season.

With the right spot and a steady routine, these plants can thrive inside your home.

The best gardenias for indoor growing

When choosing a plant, look for compact or dwarf gardenias. Smaller plants cope better in pots, are easier to shape, and suit indoor spaces far more comfortably than large shrubs. A healthy, bushy plant from a local nursery is always a good place to start.

Light matters most

Gardenias need plenty of light to flower well. Place your pot near a bright window where it gets morning sun or strong filtered light during the day. In South African homes, an east- or north-facing window usually works best. Too little light often leads to buds dropping before they open.

The right soil and pot

Good drainage is essential. Use a potting mix made for acid-loving plants and choose a container with drainage holes. Gardenias dislike sitting in wet soil, which can quickly cause yellow leaves and unhappy roots.

Watering without stress

Water deeply when the top layer of soil feels dry, then let excess moisture drain away. Keep the soil lightly moist, not soggy. Sudden changes in watering can shock the plant, so aim for consistency.

Temperature and placement

Gardenias prefer even temperatures and don’t enjoy extremes. Keep them in a room that stays between 18 – 24°C, away from cold draughts, heaters or air conditioners. A calm environment helps buds stay put.

Boosting humidity indoors

Dry air is often the biggest challenge. Gardenias love moisture in the air, so placing the pot on a tray of pebbles with water, grouping plants together, or using a small humidifier can make a noticeable difference.

Feeding for healthy growth

During spring and summer, feed with a fertiliser made for acid-loving plants. Light, regular feeding supports shiny leaves and encourages flowering. Ease off during winter when growth slows.

When and how to repot

Repot in spring if the plant has outgrown its container. Move it into a slightly larger pot with fresh mix, keeping the plant at the same depth as before. Water well after repotting and allow it to settle.

Watch out for pests

Indoor gardenias can attract aphids, spider mites and mealybugs. Check leaves regularly, especially underneath. If needed, treat early with a gentle, plant-safe solution such as neem oil.

  • How long do gardenias last? With good care, they can live for decades.
  • Are they safe around pets? Gardenias are mildly toxic, so keep them out of reach.
  • Can you cut the flowers? Yes, but enjoy them quickly – they don’t last long in a vase.

A little patience goes a long way with gardenias. Once settled, they reward you with lush greenery and beautifully scented blooms that turn any room into a calm, welcoming space.
