Can orchids be grown from seeds? When can they be grown?

1. Can it be used?

Orchids can be propagated by seeds. However, it is difficult to grow orchids using seeds and the conditions are rather harsh. Generally, orchids are rarely propagated directly using seeds, and instead division is more commonly used. Because its seeds are very small and contain only an underdeveloped embryo, they have low germination ability and the seed coat does not easily absorb water. If the seeds are sown using conventional methods, they will not germinate. The seeds can only germinate and emerge through sterile or aseptic sowing methods.

2. When to plant

Generally speaking, it is best to sow orchid seeds in spring or autumn. Orchid seeds need to be cultivated in a sterile environment, or germinated using orchid fungi before being sown. Sterile sowing is to place orchid seeds in a test tube of special culture medium and drop a certain amount of sodium hydroxide solution. Then the temperature and humidity of the test tube need to be strictly controlled, and the seedlings can only be reproduced after patiently raising them in such an environment. The reason for sowing with fungi is that orchid seeds are very small and must be combined with the orchid fungi of the mother plant to have the ability to germinate.

3. Choose a seed

It is best to choose round and full seeds, and then grow seedlings to improve the survival rate of the seeds. Plant the cultivated seeds in slightly acidic soil and mix an appropriate amount of nitrogen fertilizer into the soil. Then do not expose it to the sun. It is best to keep it in a cool place and control its growth temperature between 18-26 degrees.
