Getting Gardenia Bush to Bloom

I transplanted a gardenia bush from a pot to the ground a month ago. I planted it in a mixture of peat and potting soil and it receives sun from morning until around 2:00. I also have been giving it water soluble, acid-based fertilizer weekly. It receives water 3-4 times a week. It appears to have gone dormant and the leaves are drooping and dull. No new growth at all.  What can I do to revive the plant?

Deadheading Gardenias

I am new to gardening and this plant was a gift. Once the flower dies, should I just remove the dead petals, or how far down the stem should I go?

Deadheading removes the unsightly faded blooms, but letting them fall on their own will not hurt the plant.

Gardenia and Sunlight

We want to get two gardenias, but where we want them the sun is brutal from about 11:30 or 12:30 to about 4 pm.  I usually go out to water the plants and kinda cool them off around 2 pm. If we keep the gardenia moist during the day, could it survive the heat that long?

While in many areas they prefer partial shade, they can thrive in full sun depending on your location (hardiness zone). If your area is prone to very hot conditions during the peak afternoon, your gardenias risk scorching. Also, the area should remain relatively moist. It would probably be best to locate them in an area receiving afternoon shade if conditions in your area are hot and dry. Otherwise, it should be okay to place them in the sun, giving them plenty of moisture.

Gardenia Leaves Turning Brown

All of a sudden the leaves are turning brown on several branches on a potted gardenia. We have sprayed for white flies. Is there anything else we can do to help this problem? There is new growth everywhere on the plant.

If your gardenias have brown leaves or you notice brown spots on them, this is usually due to:

Poor drainage – Gardenias love to be moist but not soaking wet. Be sure the plant is allowed to drain thoroughly between waterings.
Not enough humidity for indoor plants – Try using a humidifier in the room where you keep your gardenias.
Not enough sunlight – Gardenias need at least eight hours of full sunlight each day.
Pests – Check your plants for pests underneath the leaves, in the soil, and on the stems.
Improper pH - Check your soil pH (it should be 5.0 to 5.5).
Rhizoctonia Leaf Spot (fungal disease) - Leaves infected with this fungal leaf spot disease have tan to brown spots up to 1/4 inch in diameter, usually begins on the older leaves and spreads upward when the plants are watered excessively or from poor air circulation. Diseased leaves should be destroyed and sterilized soil should be used.

Gardenia Buds Turn Brown Before Full Bloom

I have a potted gardenia that I have had for three years. Last year and now again this year the buds form, open part way, turn brown and die. This is a potted plant on my patio and I live in Florida.

Over Pruned Gardenia

My gardenia really suffered over the winter. In late winter, my yard person cut it back to the point there are no leaves or growth. Will it come back?

This article should help with pruning gardenia: http://www.gardeningknowhow.com/ornamental/flowers/gardenia/when-to-prune-a-gardenia.htm

It should begin coming back sometime in spring or early summer, but may take a while longer for it to bloom again.
