How to propagate blue star flowers

Soil selection

When blue star flowers are propagated by cuttings, nutrient soil, river sand, peat soil and other materials are generally chosen.

The soil must be disinfected before cuttings, and it must be loose and fertile, and some basal fertilizer can be added.

Branch selection

Blue star flower cuttings are generally made from branches. In late spring and early autumn, select tenderer branches for cuttings. You can also select old branches from the previous year for cuttings in early spring.

Cut off a section of the branch, select the healthy and thick part, and cut it into 5-15 cm long sections. Leave more than 3 leaf nodes in each section, and the cut ends should be flat.

Cutting management

Insert the cut branches into the soil and keep the temperature between 20℃ and 30℃. Do not exceed this range. Too low will lead to slow growth, and too high will cause rot at the cut end.

When the blue star flower encounters low temperatures after cuttings, it needs to be kept warm and the flower pot or container should be wrapped with film. When encountering high temperatures, you need to cool down, and the main method is sunshade and spray.

Another point about blue star flower cuttings is to keep the air humidity relatively high. Because the cuttings have no roots and cannot absorb water by themselves, it is necessary to keep the air moist, maintain moisture and reduce evaporation. Spray 3 to 5 times a day, and spray less or not on rainy days. But don't overdo it, otherwise the blue star flower will rot and die.

The cuttings of blue star flowers also have requirements for light, and they must be given appropriate light. If there is insufficient light, the plants will grow weakly. If the light is too strong, water will evaporate rapidly, which is not conducive to survival. After the blue star flower is cut, it is necessary to pay attention to shading, and wait until the root system grows out before exposing it to full sunlight.

Before the roots grow out, you can place the blue star flower in a ventilated semi-shaded place, or use a shade net to shade it.
