What to do if the leaves of gardenia turn black and dry

1. Too much watering

This is the most likely reason. Although this flower usually likes relatively humid growing conditions, everything is excessive. Once the water content in the flower soil is too high, it is very likely that its roots will be soaked in water. This will not only make the roots unable to absorb nutrients from the flower soil, but in the long run, the roots will also be rotten. Once there is a problem with the roots, the nutrient supply of the entire plant cannot be guaranteed, and the leaves will become lifeless, black, and dry.

Solution: This depends on the specific situation of the plant. If the plant's leaves are just beginning to show problems and the condition is relatively mild, we need to put it in a cool and ventilated place to let the soil dry, and then reduce the frequency of watering it; if the plant has many leaves with problems, then we need to remove the entire plant from the soil, carefully cut out the rotten roots, spray pesticides for disinfection, and then plant it in new soil.

2. Suffering from frostbite

This situation mainly occurs in winter. Many flower lovers may be a little careless and fail to prepare some cold-proof measures for it before winter comes, causing it to be frozen and the roots to freeze. It is unable to absorb nutrients from the soil, which causes the leaves to become dry and black.

Solution: This also requires taking appropriate measures depending on the condition of the plant. If it is only a mild frostbite, we can cut off the frozen branches and leaves, and then put it in a warmer place to help it recover; if the frostbite is severe, we need to take it out of the soil, cut off the frozen roots, and then cut off all the branches and leaves, leaving only one or two healthier branches, and then replant it in the pot and put it in a warm place and take good care of it.

3. Pests and diseases

Once it is invaded by some pests or pathogens, it will also have the above problems.

Solution: At this time, we need to determine what disease or insect it has, and then purchase the corresponding medicine and spray it according to the instructions.
