Detailed Explanation of Seed Propagation Methods and Technical Key Points for Doublefile Viburnum
1. Seed Collection and Treatment
This is a very troublesome step, and it also requires special attention. Around October to November, we can harvest the seeds. When the outer seed coat is observed to turn black, it indicates that they are ready for collection. After harvesting is complete, we must immediately stratify them in sand. Around the Qingming Festival of the following year, take them out, remove the fruit skin and the seed shell, and soak them in a 0.1 acid solution for about one day before sowing. Without special treatment, the sown seeds will have difficulty germinating. 2. Choice of time.
As mentioned above, it is basically the same as the time for taking out and treating the seeds.
3. Choice of Substrate
To increase the chances of successful sowing, we certainly need to choose the substrate carefully. Given the habits of this plant, the factors we need to consider when choosing a substrate include whether it is fertile and whether its drainage performance is good.
4. Specific Steps
Spread the seeds that have already undergone special treatment as evenly as possible over the substrate, then cover with a layer of soil. Note that this covering layer of soil should be slightly thicker. After that, cover with another layer of grass. Around June, the seeds can sprout and emerge from the soil. At this time, the covering grass can be removed, but appropriate shading is still needed. Only after about four or five years can formal transplanting be carried out.
5. Precautions for Transplanting
First, we should carry it out in a semi-shaded environment, and it should not be exposed to overly strong light. In addition, the timing also needs attention; it is better to do it in the early spring. Also, topdressing and water cannot be ignored.
