2. Watering Gardenia Plants
The best time to water the Gardenia plant is right after planting. Deep soak the soil in the rootball, to a depth the same as the root ball’s height.
For an extra enhancement, water the Gardenia plant with a solution of root stimulator. It will stimulate stronger root development and early root formation. It reduces plant shock and promotes greener plants.
Do not water the newly planted Gardenia plant 7 days a week. This practice causes soggy soil conditions that can lead to root rot and diseases.
If there is no rainfall presence, water only as needed. Just to retain the rootball damp to moist. Deep soaking and letting the soil dry out before watering. This is much better than watering the plants every day.
When the Gardenia plant at its mature stage, it is drought tolerant. But when you notice wilting of leaves or stems, it is the indicator that the Gardenia plant needs watering. Always check soil moisture before watering.

Fill the pot with parts of potting soil and sand. Dampen the mixture.
Dip the end of the cutting into a rooting hormone. Create a hole using your finger.
