At the beginning of spring, when the new leaves are on their way, some older leaves on gardenias may become yellow and drop off. If your gardenia is dying from root rot, it may be because of over watering. Root rot is caused by a fungus called Phytophthora infestans. It is a fungal infection of the roots of plants.
The fungus grows in the soil and causes the plant to lose its leaves. When the fungus infects a plant, it causes it to turn brown and die. Root rot can be fatal to plants, especially if it is not treated quickly. If you suspect that your plant is infected, you can treat it with a fungicide.

Do gardenias lose their leaves in the fall?
Gardenias have multiple stems and produce flowers, but don’t lose their leaves during the season. They can be grown in the garden, in containers, or as a houseplant.

A lack of magnesium causes the yellowing. In the early spring and late summer, we recommend feeding with Tui Enrich Rose, Gardenia controlled release fertiliser, and applying Tui Organic Seaweed Plant Tonic.
What do you do with gardenias in the fall?
It is best to prune your gardenia shrub right after the blooms have faded in the summer. Gardenias will set their flower buds for the next year in the fall, so pruning in the summer will allow you to cut back some of the older flowers.
What do Overwatered gardenias look like?
Generalized leaf yellowing, often starting with lower, older leaves first. New growth is affected by the brown leaf tips. Bud drop despite adequate light, temperatures, and humidity. The best way to determine if your gardenia is suffering from over-watering is to look at its leaves. If the leaves are yellow or brown, it is likely that the plant has been overwatered and needs to be repotted.
How often should gardenias be watered?
Gardenias require at least an inch of water a week. To control water-hogging weeds and keep the soil moist, apply mulch to a depth of two to four inches. Don’t let the plants become completely dry before you water them, and don’t water more than once every two weeks.
If you’re using a garden hose to water your plants, make sure the hose is properly connected to the water source. If it’s not, it could cause a fire hazard.
What do gardenias look like in the winter?
Gardenia plants look and smell gorgeous in the spring and summer. They begin to lose their color during the fall. You can expect the plant to die if it gets a severe touch of frost or if the leaves turn brown. The best time to plant a Gardenia is in late spring or early summer when the weather is warm and the soil is moist.
You can also plant them in early spring if you want to get the most out of them, but it’s best to wait until after the last frost has passed before planting them. If you wait too long, the plants will die and you’ll have to replant them again.
Is my gardenia dead or dormant?
You can lightly scratch the bark with your thumbnail. If the cambium layer just beneath the bark remains green, hope is not lost. If no new growth occurs after several weeks and the cambium tissue dries out, your plant is dead. Without leaves, your gardenia won’t need as much care as a dead plant.
How do you winterize gardenias?
Prune your gardenia in the late summer before winter. The second step is turning off the water to the shrubs. Gardenias can be moved to warmer locations that receive sunlight. If you want to keep the soil moist, apply a slow-releasefertilizer.
