Gardenia Has Yellow Leaves? Do This One Step and Whatever You Do, Don't Let It Bloom

Today a fellow gardener brought me a gardenia with yellow leaves. They didn't know the cause, and even less how to save it. So let's take a look at this plant today.

This gardenia, the whole plant still looks fairly lively, but it has a large number of yellow leaves, and they have already fallen off. This is caused by the potting soil not being breathable. Gardenias need loose, breathable soil. This soil is clearly yellow clay soil, which easily causes water to stagnate, so the roots can't breathe, and yellowing and leaf drop occur!

This gardenia is in its flowering period. You can change the potting soil after it finishes blooming. At this point, after watering, place it in a ventilated environment so the potting soil can quickly release some moisture through evaporation, keeping the soil just slightly moist. Whatever you do, don't let it become waterlogged.

When the roots can't breathe and nutrient uptake is poor, all kinds of problems easily arise: yellow leaves, leaf drop, and bud drop.

If the leaf drop is too severe, then to save this gardenia, repotting during the flowering period is also necessary. When repotting, first soak the roots apart in clean water and pot it up bare-root, which reduces damage to the roots. The potting soil must be loose and breathable. You can use leaf mold, large-grained river sand, and mix in one part pine needles to make the soil slightly acidic.

You can prune away some of the damaged branches, dead branches, weak branches and spent flowers, then cover it with a plastic bag to retain moisture. Poke a few holes in the bag for ventilation, and keep it in a spot with bright, indirect light and good air movement. After a week, gradually open the plastic bag and care for it normally.

After repotting, yellow leaves may still appear. This is the result of the roots not having fully recovered. The yellowing will gradually lessen, but these flower buds most likely won't bloom. After all, keeping the plant alive is what matters most right now. If it grows vigorously, it will still bloom with a full pot of flowers in autumn.
