How to identify blind branches of tree-shaped Chinese roses
Have the friends who raise tree-shaped Chinese roses encountered this situation: the branches of the roses only grow leaves but no flowers? In this case, you should pay attention to whether you have encountered a blind branch.
As long as Chinese roses are cultivated properly, they can bloom with branches (note: it's the new branches of the current year), the flowering form is from axillary buds or latent buds, then bloom at the top of the branches, so it can be concluded that any Chinese roses, regardless of the variety, will definitely bloom as long as there are branches!
And those branches that cannot bloom, we call them blind branches! These branches no longer differentiate into flower buds and leaf buds, and their growth停滞s, so they are also called topped branches.
So, how to identify blind branches? The main thing is to see if there is an obvious bud at the top of the branch.
The main reasons for forming blind branches are as follows:
1. Lack of fertilizer. As we all know, Chinese roses are fertilizer-loving plants. They grow a lot and bloom many flowers, so without nutritional supplements, they will naturally become wilted.
2. No pruning in winter. Chinese roses can only bloom on the thick branches of the current year, so pruning is necessary every winter to promote the growth of new flowering branches the following year.
3. Insufficient sunlight. The reason is similar to that of lack of fertilizer. With less photosynthesis, there is also less nutrition to nourish flower buds. It is best to have more than 6 hours of sunlight a day to ensure adequate nutrition.
4. Low temperature. Generally, temperatures below 12°C are prone to blind branches.
5. Lack of water, soil compaction.
So, what should we do after finding blind branches? Cut them off! After all, we plant Chinese roses to admire the flowers.
The method of pruning is also very simple. Follow the blind branch downward, find the most plump bud point, and cut off the upper part of the branch about 1 centimeter above the bud point. After removing the apical dominance, the remaining bud points will sprout new branches.
In addition to that, it is also necessary to strengthen watering and fertilizing, and improve according to the reasons for the formation of blind branches.
Of course, if the seedlings are very small or all are blind branches, it is recommended to keep the blind branches, strengthen sunlight, water, and fertilizer. As long as there is enough nutrition, these blind branches will eventually sprout.
