Best Uses For Growing Gardenia Varieties

Because of their delightful fragrance, plant Gardenias in areas where people will pass or sit frequently. Examples include:

  • Bordering a Porch or Patio
  • Beneath a Window
  • Flanking a Gateway
  • Beside Steps
  • Along a Path
  • At Poolside

Gardenias are acid-loving plants that do well as container plants and are often the best way to grow them.

This allows for moving them to more protected areas during cold or inclement weather. Always protect these delicate plants from very harsh, cold winter winds.

General Gardenia Care

Many Gardenias are grafted on Gardenia thunbergia rootstock.

It’s best to water using a drip irrigation system to prevent getting water on the plants’ leaves reducing potential leaf spots.

Help keep the acidic soil moist around plants by mulching. Avoid placing mulch against the plant stems as this may cause rot.

In mid-March, give your Gardenia plants a feeding of blood meal, fish emulsion, or commercial acidic plant food. Provide another feeding late in June for better blooming.
