What's going on? The cutting rose has already sprouted but suddenly wilted.

This is the 875th day of the Blue Devil's daily original article.

Rose aquaculture series article 73

A few days ago, the blue demon shared the cutting method of the rose, and many flower friends went to practice after seeing it, some successful and some failed.

We say that the reasons for success are roughly the same, but the reasons for failure are various. yesterday, a flower friend asked the blue demon, how did his cutting rose sprout, but suddenly withered?

I believe that there must be a large number of flower friends who encounter similar problems, what is the reason for our cuttage failure? The reasons for the failure of cutting: the reasons for the failure of rose cutting can be roughly divided into the following six types.

1. Disinfection is not in place when cutting rose when the temperature is high, we must disinfect the branches and soil, because the high temperature bacteria multiply quickly, such as disinfection is not in place, it is easy to lead to cuttage failure due to black pole.

2. Cutting soil contains bacteria fertilizer cutting rose is best to choose sterile and non-fertilizer plain soil, blue demon recommends pure vermiculite or pure perlite cutting, the probability of relative black pole will be much smaller.

3. The branches are not strong enough. Many flower friends do not know what kind of branches should be selected for rose cuttings. They think that the thick old branches are good, but the old branches are not strong enough to survive.

The best rose cuttings should be pruned branches just after blooming, or cut off the residual flowers after flowering, and then cut off the branches in a week. Such branches have sufficient nutrient storage, and their own branches have a high degree of maturity, which is easy for cuttings to take root.

4. Unreasonable pruning rose cuttings need to consume nutrients before taking root, because the branches are not easy to stay too long. Some flower friends are more eager to cut the whole branch, so it is very difficult to survive, because the branch is too long to consume too many nutrients, which is not enough to wither until the branch grows root.

The pruning of cuttings should retain 1-3 bud points, depending on the distance between the branches. The total length of cuttings should be controlled within 10cm. 5, although the variety relationship is rose, but there are some rose varieties cutting is more difficult to survive, often good varieties of rose, cutting will be relatively difficult, more use of grafting propagation.

Therefore, if you cuttage a certain variety of rose, always the cuttage is not alive, and other varieties can successfully take root, it can be judged that it is the problem of the variety, not the operation. Compared with our family reproduction, the conditions are still limited.

6. Flower friends who often play with cuttings when the temperature is too high will find that in late spring or summer, rose branches often begin to sprout a week or two after cutting. it looks very exciting, it seems to be alive, but it is actually fake. What is a fake job? As the name implies, false survival, normal cuttage successful branches will not sprout so quickly, basically it will take about 40 days to germinate and grow, and premature germination is basically a fake phenomenon.

In addition to the relationship between species and temperature, the reason for fake living has a lot to do with it. When the air temperature is higher than the soil temperature, it often causes false activity, so it is most likely to occur in late spring and summer.

So the timing of cutting is also very important. Of course, in principle, rose can be cut all the year round, but for our family breeding cuttings, the conditions are limited, choosing the right time cuttings can get twice the result with half the effort.

In general, early spring, late autumn and winter are more worry-free time for cutting, with simple management and high survival rate. The high temperature in late spring and summer often leads to cuttage failure due to bacterial infection and high temperature.

The above is the blue demon on the rose cutting failure of a little summary and analysis, I hope to enlighten you.
