For roses, their seeds have another characteristic: dormancy, in fact, this is not only rose seeds, many crop seeds will have this characteristic. Garlic, for example, needs to be planted after a dormancy before it can sprout. The same is true of rose seeds. If the newly harvested seeds are sown directly, they will certainly not germinate. You can wrap up the seed newspaper and put it in a refrigerator at 4 degrees Celsius. After more than a month, you can take it out and sow it in the coming year. Otherwise, spring flowers will not sprout without dormancy.
In addition, seed vigor is also a major factor, some seeds, due to improper storage, seed vitality has been lost, at this time certainly can not germinate, therefore, the premise of seed germination is that rose seeds have vitality.
And like the planting method of roses is also another major factor in germination, for example, the planting depth is too deep, or the depth is too shallow is not conducive to germination, too deep, the seed breathing is not smooth, too shallow, can not make good use of water, and after sowing as far as possible to keep the soil moist, in order to facilitate germination.

Seed reproduction is not only a long planting cycle and slow growth, but also not conducive to maintaining the stability of flowering characters after planting. However, asexual reproduction is different. Rose cutting is not only convenient for reproduction, but also can quickly obtain buds after cutting.
Here is science to promote agriculture, welcome to add attention, with you to grow knowledge.
