What to do if your gardenia gets frostbitten? Here are the correct remedies
1. Rescue methods
(1) You can first observe the plant's frostbite. If it is only mild frostbite, that is, only the leaves and thin branches above ground are frostbitten, you can first move the plant to a relatively warm place, but do not place it directly in a place with a relatively high temperature, then cut off all the frostbitten parts. In addition to normal watering, also spray more water around the plant, as this helps it recover.
If the frostbite is relatively severe, then dig the entire plant out of the soil and check whether its roots have been damaged. If the roots are still fairly fresh, that means it can still be saved. When digging, be very careful not to damage the root hairs.
(2) Cut off all the damaged branches and leaves above ground, keeping only one to two of the better branches.
(3) After pruning, replant it in a pot, then place it in a place that does not get direct sunlight and has a suitable temperature. Likewise, it must not be placed in a place with too high a temperature.
(4) Water normally, but the water temperature must be the same as room temperature, and there must be no standing water, nor should the potting soil be too moist; at the same time, spray water around the plant every day to make the air more humid, as this helps its new buds sprout.
(5) After about a month, you can see new small buds growing out. At this point, carry out appropriate thinning and pruning and it will return to normal.
2. Precautions
(1) When digging out the plant and pruning branches and leaves, you must be careful and must never damage its root system, otherwise it may very likely cause a flower that could have been saved to wither and die.
(2) If the root system of the dug-out plant has already been completely frostbitten, then there may truly be no way to save it, and it is recommended to buy a new plant to grow.
