The distance between branches and leaves of Gardenia jasminoides Ellis is far, and the plant type is scattered, which is obviously a virtual long state. In addition to the high temperature in summer and high temperature, it should be shaded appropriately, and it should be kept in a position with sufficient scattered light in other seasons. Gardenia prefers light to direct light. In addition, the leaves of Gardenia jasminoides Ellis have slight iron deficiency symptoms. Gardenia is sensitive to iron deficiency, and the new leaves at the top are yellow. Every half a month or so, ferrous sulfate should be poured to adjust the PH value of the soil to acidity.

Gardenia pruning is divided into growth pruning and dormancy pruning. Pruning in the growth period is generally from May to July, and pruning in the dormancy period is generally around 65438+February (it can be in1-February in the south). Generally speaking, gardenias don't need to be cut again. If there is no big problem, just gently cut it, and 2-3 pairs of leaves under the branches can be cut off. For overgrown branches, overgrown branches, diseased branches or basal buds, it is necessary to prune them again.

It is suggested that gardenia should be pruned after it enters the dormant period, which will be more casual indoors in the north. First, prune the twigs and weak branches that grow at the bottom. This kind of branch will cause the plant to grow too densely, and the ventilation is not smooth, which is easy to cause pests and diseases. And it's hard to blossom, and it's useless to keep it. Just cut it off from the root. Second, cutting off horizontal branches or internal branches will affect lighting and ventilation. Look at the topic, this pot of gardenia has many branches. After removing the transverse branches, the nutrients will flow to other branches and promote the growth of outward branches. At this point, the overall structure should be relaxed a lot, and then the last step. Third, observe the branches from the base, keep the thicker branches and cut off the thinner ones. This gardenia should be younger. Keep 5-6 main branches first, gradually cultivate obvious main branches and then keep 3-5 main branches.

Then comb each main branch, and there should not be too many branches at the upper level of the main branch, only 2-3 branches are enough, and the redundant branches with poor orientation are directly removed. Finally, lightly cut the remaining branches in different degrees (2-3 pairs of leaves or more below the tip of the branches), and pay attention to selecting outward bud points at the pruning position, so that the plant type is close to mushroom type and the branches are evenly distributed.
