Can an orchid be obtained from a seed? The cultivation of orchids from seed usually takes place in a highly controlled environment, because it requires special care that, probably, a non-expert will never be able to guarantee their own. orchid seeds.

In other words, plant orchid seeds indoors it's difficult, very difficult. But it is still possible to do so, as long as you have a lot of time and patience. Keep in mind that even if you are successful in the germination of orchid seeds, it takes a month or two for the first leaflets to develop, and it may take years to see the first bloom.

Therefore, it is very easy to understand why orchids are so expensive!

How to grow orchids from seed

Learn to grow orchids from seed it's really hard, but - hoping to please you - we've provided some basic details for you to consider. Obviously, if you want to embark on this undertaking with even greater awareness, our suggestion is to ask for personalized support from an expert gardener.

That said, you will notice that the orchid seeds they are incredibly small. Suffice it to consider that in a "tablet" like those of a common cold medicine it weighs more than 500,000 orchid seeds! Sure it is that some types of orchid seeds may be slightly larger, but the proportion will still be astounding.

Also, unlike most other plant seeds, i orchid seeds they lack nutritional storage capacity. In their natural environment, therefore, the seeds will have to land on a soil containing mycorrhizal fungi, which will enter the roots and convert the nutrients into usable form.

Germination techniques

As regards the germination techniques, we summarize below how botanists mainly use two techniques to make sprout orchid seeds.

The first, the symbiotic germination, is a complicated process that requires the use of mycorrhizal fungi, as described above. The second, the asymbiotic germination, consists in germinating the seeds in vitro, using agar, a gelatinous substance that contains the necessary nutrients and growth hormones. Asymbiotic germination, also called flasking, is easier, faster and more reliable for growing seed orchids at home.

Sterile conditions

The seeds (usually seed pods, which are larger and easier to handle) must be sterilized without damaging the seed. There sterilization for the germination of orchid seeds in the home it is a process that generally requires boiling water, bleach and lysol or ethanol. Similarly, all containers and tools must be carefully sterilized and the water must be boiled. Sterilization is difficult but absolutely necessary; although orchid seeds thrive in the gel solution, as do a variety of deadly fungi and bacteria.


The orchid seedlings they usually need to be thinned out at around 30 - 60 days, although it can take much longer for seedlings to reach transplant size. Each seedling is moved from the original container to a new container, also filled with agar similar to gelatin. Eventually, the young orchids are moved to pots filled with coarse bark and other materials. First, however, the young plants will have to be placed in hot water to soften the agar, which is then removed by washing in warm water.

How not to spoil your orchids

Orchids have a reputation for being very difficult flowers that require high maintenance. They need a specific environment to thrive and, having put great effort into making them happy, it can be frustrating when serious problems arise that could lead to their premature death.

In short, seeing the flowers of your orchid fall prematurely, usually in response to some kind of environmental "trauma", is certainly not easy. But how to avoid this situation?

The causes of orchid bud fall they can be multiple. In nature, orchids grow in a tropical environment. And, in nature, there are many types of orchids you may encounter. So, the best thing you can do is research the specific needs of your particular strain. Most of them need a lot of light and humidity, and you should try to imitate as closely as possible the natural environment in which the orchid's ancestors were born.

For example, try placing orchids in a south-facing window, where they will get plenty of sun, or under an indoor grow light. Create the right humidity with a humidifier, with daily mist, or place them on a tray full of pebbles and water. Make sure the temperature in their environment drops by around twenty degrees at night to induce flowering. Water thoroughly once a week and be sure to let the soil dry between one watering and the next.

Remember that watering orchids with water that is too cold or too hot can stress your plant and cause orchid buds to drop. So check the specific temperature needs of your orchid variety and make sure you keep the temperature constant.

Furthermore, it is rather however that orchid buds can fall due to the aggressiveness of chemicals in the air, such as perfumes, paint vapors, gas leaks, cigarette smoke, ethylene gas from ripening fruit and methane released by flowering plants. Excessive fertilization or the application of pesticides can also push the orchid over the limit, as well as watering too much or too little.
