Because primrose is a kind of perennial herb, cutting method is also a kind of propagation method it can use. The time selection is flexible. As long as the temperature meets the requirements, it can be used in all seasons of the year. If it's outdoor, you can choose April, may and June
1. Cuttings: two year old and robust branches should be selected. The best length is 12-15cm. Before cutting, cut off the lower part of the leaves. Then cut the lower part into a beveled opening. It can be treated with rooting powder solution. After soaking for several hours, rooting will be faster.
2. Matrix: it should be soft, permeable and easy to seep. It can be made by mixing humus with river sand.
After the cuttings and substrate are prepared and processed, the cuttings can be cut. You can make a few holes in the substrate first, and then insert the cuttings obliquely. Don't go too deep
After inserting, water it once and thoroughly. Then, it should be placed in a ventilated and shady place. If the daytime light is too strong, you can use tools such as templates to shade properly. In addition, the substrate should be kept moist. If it is dry, it can be replenished and humidified by spraying water, but it is not allowed to accumulate water. The temperature should be kept between twenty and twenty-five degrees.
