Prune gardenias like this, and the cuttings from trimmed branches can easily become dozens of pots

Gardenias, if planted in a yard, can be left alone, and after a few years they will grow into a flowering tree with lush branches and leaves, flowers all over the branches, and fragrance carried far away, very spectacular
For potted gardenias, to keep the plant shape beautiful, you have to prune them properly.
After the flowers fade, you should prune off the leftover branches and stems, in order to keep the plant shape beautiful and also to reduce nutrient loss.
After the flowers fade, with sufficient nutrient supply, many new buds grow from the top of the plant. After these new buds grow for a period of time, you can prune them according to your own preference. Generally, keep two to three nodes of leaves and cut off the rest. After these branches are tipped, they will gradually age, and from the aged branches many small side branches will branch out again. When they have grown a bit, keep the parts you need and then cut off the excess bud tips, and repeat this cycle. During this period, water and fertilizer must be supplied adequately, and you must not let it go short of fertilizer! Gradually, your gardenia will have a beautiful shape!
After entering autumn, the gardenia grows slowly, and at this time you should stop pruning. At this time it is about to enter its flowering period, so care should be the main focus. You can use phosphorus and potassium fertilizer two to three times a month to promote flower bud differentiation, and with reasonable light, it will produce many flower buds. After the buds appear, stop fertilizing and just wait for it to bloom.
If you want to propagate small gardenias yourself, do not prune the branches too early. Wait until they become sturdy small branches, then cut them off, and you can just use them for cuttings! Cuttings from new branches are also feasible. Not only do you shape the plant, but you can also get a small gardenia in its early form, very nice!
The beauty of the gardenia is mainly its floral fragrance. Propagating a few pots yourself gives a special sense of accomplishment. When they bloom together, the feeling of fragrance filling the garden is especially beautiful!
