The rose seedlings purchased online have been planted for more than a month. The main reasons for not sending new roots are these two.

The root system of the new rose seedlings does not develop. In other words, it is not suitable for the pot. After the new seedlings are planted, the root system does not extend from the original soil ball to the new soil. There are several reasons for this. First, the substrate difference, the second is fertilizer and water management, and in addition, there are details such as maintenance and season.

First of all, the soil difference, for example, the bought rose soil ball is prepared artificial matrix, good air permeability, planted matrix is loess, or bought yellow mud seedlings, planted artificial matrix, this kind of original soil ball matrix and subsequent planting matrix structure difference, will limit the development and extension of root system, this is also many flower friends buy back seedlings.

Finally, the seedlings hang up, and when they are dug out, they find that the roots have not taken root in the new soil at all, that is, they have not taken root in the pot, so the new seedlings must not be too different from the original soil matrix structure. The second is fertilizer and water management. After planting seedlings, I will sprinkle some controlled-release fertilizer on the surface of the pot soil. In this way, with the release of controlled-release fertilizer, the root system can be slowly induced to grow to new soil, which is the fertility of the root system.

However, there were also some other problems. For example, the seedlings themselves were very weak and did not grow well enough, causing the photosynthesis of the seedlings 'leaves to be too weak to provide sufficient nutrients for the root system to develop. Or, the pot soil was too stagnant, causing the root system to be difficult to develop. There was even too much base fertilizer added, which played a role in burning the roots... Therefore, the seedlings bought in spring could be quickly planted because the climate was suitable and the seedlings were in good condition. This was also one of the reasons for the season.

Therefore, in order to make new seedlings grow at home as soon as possible, it is necessary to cultivate roots well, root seedlings red, reasonable management of diseases and insect pests and water and fertilizer management. I personally plant roses after receiving seedlings temporarily do not pot, first pour water, then spray broad-spectrum fungicides (such as mancozeb), and then put in shade (preferably mottled sunlight), slow seedlings for about 3 days before planting, the effect is better, flower friends can try.
