Gardenia Jasminoides Care

Gardenia Jasminoides care can be difficult, especially for inexperienced growers. With the proper care and maintenance, the Gardenia Jasminoides should grow without hitches. 

Light Requirements

Gardenia jasminoides grown in containers indoors performs better when placed in a location with access to bright indirect or filtered sunlight. Gardenia plants need between 6 and 8 hours of filtered sunlight daily.

Exposing the Gardenia Jasminoides to direct sunlight over a long period will cause its leaves to burn and its buds to fall.

Gardenia jasminoides thrives in south-facing windows with a glass filter. This is because it receives the most light throughout the day.

Soil Requirements

Gardenia jasminoides prefers soil that is consistently moist and well drained. Avoid over-watering the soil. Instead, aim to keep the soil damp without causing waterlogging.

To achieve a well-draining potty mix, add perlite, peat, and orchid bark to your soil. This will aid the easy movement of water and nutrients within the soil.

Make drainage holes at the bottom of the pot and also cover the top of the soil with mulching materials to retain the soil moisture. 

Water Requirements

When you notice that the top of the soil is starting to dry out, water the Gardenia Jasminoides plant right away. Avoid letting the soil get overly dry before watering.

When watering, soak the entire soil until it starts dripping out through the drainage holes under the pot.

Over watering can cause damage to the plant’s leaves and roots. Yellowing of leaves and root rot are signs of overwatering.

Fertilizer Requirements

Feeding the gardenia jasminoides should be done every 3 or 4 weeks during the growing season. Use a well-balanced acidic fertilizer, diluted to half its strength, to feed the plant.

Using fertilizer at full strength is not advisable as it can damage the roof of the plant.

During the winter season, stop fertilizing the plant as doing so will cause root burn.

Temperature And Humidity

Gardenia jasminoides loves a warm environment. For indoor cultivation, try to maintain a household temperature that’s above 65 degrees Fahrenheit. Also, they love humidity, so endeavor to keep the humidity level above 60 percent.


The Gardenia jasminoides’ size can be controlled through pruning. Pruning should be done only when the Gardenia Jasminoides has finished blooming.

Old, infected, and dead leaves and stems should be properly pruned away using a pair of scissors or pruning shears to cut them off. The main benefit of this is that it allows the plant to focus on creating new leaves instead of trying to heal the old ones.


The best method for propagating Gardenia jasminoides is through stem cutting. Ensure the cut you are using is from a healthy plant.

Make a stem cut about 4 inches long. Remove all the leaves on the stem, leaving only the top two sets. Put the cutting in a glass of water. The water used should be changed every 2 days.

After a while, you will see new roots starting to form. When the roots reach 2 or more feet in length, move the cutting to a potting mix already prepared. Carefully dig a hole in the middle of the pot and place the stem cutting inside. Water after being placed in a bright environment.

Common Health Problems/Pests And Diseases

Common pests that attack the gardenia Jasminoides plants include mealybugs, aphids, ladybugs, etc.
