Growing Beautiful Gardenias

Gardenias worn discovered In China In the 1700’s. Their fragrance is unmatched in the floral world, and the extracted oil from the flowers is used in making perfume and tea.  They are not hard to grow if you meet the plants basic requirements for good health:

Light: Gardenias need at least 4 hours of sunlight a day. During the hot summer months, a light curtain filters out some of the intensity and protects foliage. Without this much light, the plant won’t bloom.

Water: Gardenias do not like to dry out. Keep the soil moist but not sodden. They should never be allowed to stand in water. During the winter the plant may use less water due to reduced light levels. Cut back on the watering, and let the top 1/2 inch of soil go dry before watering.

Humidity: Gardenias do enjoy humidity. If the winter air in your home is dry, especially it you heat with forced hot air or woodstove, try growing your plant on a pebble tray. Get a large plastic plant saucer. Put a layer of gravel in it about 3/4” deep. Pour water into the stones, but do not let the water reach the top of the gravel where the plant roots could come in contact with it. Place the pot on the wet stones. As the water evaporates, it forms a little pocket of humidity that the plant can enjoy.

Temperatures: This is a crucial point if you want your plant to bloom. During the day, temperatures that are comfortable to humans are fine for gardenias. At night, temperatures should drop to 60-65 degrees. The flower buds will drop off if temperatures are higher.

Fertilizer: Gardenias need an acid-based fertilizer to keep the soil at the proper pH. Fertilize one time in spring and one time in Fall with Miracid.

Repotting: Use a peat-based potting soil to which no lime has been added. Gardenias do not need to be transplanted frequently, only when their roots have almost filled their pots. Soil should be well-drained.

Bud Drop: Usually caused by plant stress, not enough water, humidity too low, and temperatures too high. Problem is usually self-correcting if above plant needs are met.
