What to do if the black stem appears when transplanting roses
Regular flower enthusiasts should know that it is recommended to buy rose seedlings in autumn, as they are relatively easier to survive. After winter dormancy, they have abundant nutrient reserves and can grow stronger in spring. However, some flower friends have left messages saying that they have planted roses several times, but each time ended with black stems. Why is that?
Why can't the newly bought roses survive?
To answer this question, we need to analyze from the following two different perspectives.
1. The condition of the seedling itself
This flower friend said that they have planted roses several times, but all ended up with black stems. From what I understand, our flower friend is planting bare-root rose seedlings. Of course, it is not that bare-root roses cannot survive, but bare-root roses have high requirements for planting time.
If you want to plant bare-root rose seedlings, it is recommended that you plant them in late autumn or early spring. If the temperature in winter is around 0 degrees, planting bare-root seedlings in winter is also very easy to survive. Planting bare-root roses in these three time periods basically does not need to worry about survival issues, but if it is at other times, it will be more difficult.
For example, now in autumn, the daytime temperature is still above 20 degrees. At this time, roses are still in a period of vigorous growth, new buds grow quickly, and the consumption of new buds is also high. If you transplant bare-root roses at this time, the new buds are prone to withering and drying, and if not managed properly, the entire plant may turn black.
Even if the roses have been pruned heavily, during bare-root transplantation, severe root damage will seriously affect the germination of new rose buds, resulting in weak growth of new buds and the whole plant becoming weak.

In order to ensure the healthy growth of the seedlings, unless there is no choice, Green Plant Enthusiast Network recommends that you still choose potted seedlings during the growing season of roses. It is more reliable and worry-free to transplant with the original soil after receiving the seedlings, and it is very easy to survive in autumn without delaying the growth of new buds.
2. Management after transplantation
Of course, in addition to the problems with the seedlings themselves, our management also directly affects the survival of the seedlings.
For example, many bosses who sell bare-root seedlings teach customers to plant them in a cool room after planting, away from the sun. Then, the roses will sprout new buds. When flower friends see the sprouts, they think the plants have survived and are very happy. However, the buds are very weak and even yellow, and they will wither directly when exposed to the sun.
Some flower friends, although they plant potted rose seedlings, still end up with black stems and wither after移植ing with soil. In this case, it is necessary to focus on checking the following two aspects:
① Overwatering causing root rot
Many flower friends often make the mistake of overwatering, especially beginners, who always worry that the roses will die of drought and water them every day. However, the newly transplanted rose seedlings have roots that have not yet adapted to the new soil environment and have较弱 absorption capacity, so the consumption of water is naturally not as much.
