What to do if the roses do not take root after cutting
Sharing with everyone how to deal with roses that do not take root after cutting and the detailed knowledge of three small tips for promoting root growth in roses, the specific content is as follows:
Many experienced flower growers choose to cut roses in spring because the branches are rich in nutrients, full of vitality, and the temperature is also suitable for cutting propagation, which can help the cuttings take root faster.
However, there are also some flower growers who always fail to cut roses, and each time, before the cuttings grow roots, the bottom starts to rot, leading to repeated failures. In fact, it is not that difficult to cut roses, and you can try using the following three "small methods" to cut them, which can make the cuttings take root faster and improve the survival rate of cutting.
One, sterilize and disinfect the matrix and cuttings
No matter which season you cut roses, as long as the method is correct, there is actually a very high survival rate. The reason why the cuttings rot is mostly because they are infected with bacteria at the wound site during operation, leading to black rot. If you do a good job of sterilization and disinfection in advance, you can avoid the rot of cuttings.
1. Treatment of cuttings
Cut the rose branches into cuttings about 10 cm long, with the bottom cut at a 45-degree angle. After completion, it is best to sterilize the wound because the tools used may carry bacteria, leading to bacterial infection of the cuttings.
You can first treat the cut cuttings with sterilization and disinfection, soak them in potassium permanganate diluted with water for 20 minutes, then rinse them with clean water before cutting.
2. Treatment of matrix
The matrix is the culture soil used for cutting, which is also a key detail for the cuttings to root quickly. If the soil has too much stickiness and poor permeability, it is difficult for the cuttings to root. However, if it is loose and breathable with moist pot soil, the cuttings will root more easily.
The matrix used for cutting should be loose and breathable, commonly used are river sand, coal slag particles, coconut bran, sawdust, and vermiculite, which have a good effect on root growth.
What to do if the roses do not take root after cutting
The culture soil should be sterilized and disinfected before cutting flowers, especially those with decomposed leaves, because the soil will also carry a large number of bacteria, which can cause the cuttings to rot.
You can place the culture soil in the sun for a few days before using it, or mix it with an appropriate amount of carbendazim for sterilization before cutting to reduce the rot of cuttings.
Two, use root-promoting water to assist in root growth
When cutting flowers at home, especially those woody flowers that are not easy to root, it will grow very slowly if left to root naturally. Using a little root-promoting water during cutting can make the cuttings root faster and have a higher survival rate.
After sterilizing and disinfecting the culture soil and cuttings, prepare to cut by placing the cuttings in the prepared root-promoting water and soaking for about 20 minutes before cutting them into the matrix, which can speed up the rooting of cuttings and make the roots thicker.
If you don't have root-promoting water at home, you can also use sugar water or honey water as a substitute. Soaking the cuttings in a light sugar water or honey water for about half an hour before cutting can also promote root growth.
Three, promote root growth through hydroponics
If cutting with soil always fails and results in failure each time, you can try the hydroponic method of cutting next time. This method roots faster and allows for a more intuitive understanding of the rooting status. The downside is that after the roots have grown, moving the plant may damage the tender roots and affect the survival rate.
When cutting roses using the hydroponic method, after cutting the cuttings, you only need a few disposable cups as culture vessels, add 1/3 pure water, and preferably a drop of root-promoting water, then place it in a warm and ventilated environment. It will grow roots in about half a month.
When the roots grow to 2-3 cm and the top starts to sprout new buds, replant them in loose and breathable culture soil.
Conclusion: Spring is the perfect season for cutting roses due to the suitable temperature. If you have always failed to cut in the past, you can follow the above points, choose strong branches as cuttings, sterilize and disinfect the matrix and cuttings, and use root-promoting water as an auxiliary if conditions allow, which can effectively improve the survival rate of cutting.
