A newly bought gardenia must have this step done first, otherwise yellow leaves, leaf drop and death will follow

Hello everyone, today let's talk about gardenias. Xiao Qi used to grow gardenias; after growing them for a while, they became easy and took up quite a bit of space, so I gave them away. Now many flower lovers often ask about gardenias, so I bought another pot back from the flower market.
The gardenias we just bought home usually come in very hard, compacted yellow clay soil. Because when we buy them they are all in flower, at this time do not repot them. Once repotted, the roots get damaged, the flower buds will drop in large numbers, and the leaves will wilt. This is exactly why many friends say that the gardenia they bought wilted right after repotting.
There is another reason the leaves wilt: the gardenias we just bought have very hard, very compacted yellow clay soil. After watering, within a few days it dries out. This gardenia of mine was watered just one day ago, and the leaves are already a bit wilted; the water cannot soak through.
So if we cannot water it through, what should we do? We can use a basin, put water in it, set the gardenia's pot in it and soak it, letting the soil soak thoroughly, then take it out and set it aside. But we cannot wait until all the gardenia's leaves are wilted before watering again, as that will damage its roots.
When we feel the soil has dried, water it thoroughly right away.
If a gardenia goes short of water once, the leaves may not show anything obvious; short of water twice, the leaves begin to wilt and turn yellow; short of water too many times, the flower buds begin to drop in large numbers. This is why many flower lovers' gardenias get yellow leaves and drop flower buds.
While it is blooming, try not to repot it; wait until it finishes blooming before repotting, and do not fertilize.
