The use of water plugs in the Chinese rose breeding has a very high survival rate. Now introduce the method of rose water intercropping to friends who like rose flowers for reference.
After the Chinese rose flowers, cut off the residual flowers, and let the flower branches grow for several days, until the first bud on the flower branches grow thicker. Accumulate nutrients, then cut 3 cuttings. Remove the petiole of the bottom layer and use a sharp blade to cut the bottom bud into a bevel and immediately insert the bottle that has been filled with clean water. Inserts can be inserted in 1/3 of the water. To reduce the evaporation of leaf moisture. Partial blades can be cut off. In the absence of light. The incision is easy to grow new roots, so brown bottles are used. If there is no brown, a black plastic film can be wrapped around the bottle. Insert the bottle on the south-facing window sill and do not directly basking in the sun.
When the temperature is high, the water can be changed once a week. The temperature can be as long as 20 days at 15~25°C, and the young root can grow to 1~2 cm long. Can be transplanted in pots. As the young root grows in the water, in order to adapt it to the environment, watering begins once a day when transplanting, and gradually decreases afterwards. After a week of shading, you can see the sunlight sooner or later. You can survive.
The advantages of the water-insertion method are: simple method, high survival rate, no restriction on the time, and can be cut after the flower is cut.
