How to Grow Orchids from Seeds

Orchids are among the most diverse and fascinating plants in the world. They have more than 25,000 species and over 100,000 hybrids, and they can produce stunning and fragrant flowers for months. However, orchids also require some care and maintenance, especially when it comes to propagating them. Growing orchids from seeds is one of the most challenging and rewarding ways to multiply your orchid collection, but it is not a simple or quick process.

In this article, we will explain how to grow orchids from seeds using different methods, tools, and tips. We will also answer some of the most frequently asked questions about orchid seed germination and cultivation. By the end of this article, you will have a better understanding of how to grow orchids from seeds and why it is important for orchid lovers.

How to Grow Orchids from Seeds

There are two main methods of growing orchids from seeds, each with its own advantages and disadvantages. Here are the two methods:

  • Symbiotic germination: This method involves sowing orchid seeds in their natural environment, where they can form a symbiotic relationship with a specific type of fungus, called mycorrhiza. The fungus helps the orchid seeds to germinate and absorb nutrients from the soil, while the orchid provides the fungus with sugars and other organic compounds. This method is suitable for orchids that are native to your area, or that have similar climatic and ecological conditions. This method is also suitable for orchids that have large and viable seeds, such as cymbidium, epidendrum, or masdevallia. This method is more natural and eco-friendly, but it is also more difficult and unpredictable, as it depends on many factors, such as soil quality, fungal availability, seed viability, and environmental conditions.
  • Asymbiotic germination: This method involves sowing orchid seeds in an artificial environment, where they can grow in a sterile and nutrient-rich medium, such as agar. Agar is a gel-like substance that contains water, sugar, minerals, and hormones, and that can support the growth and development of orchid seeds. This method is suitable for orchids that are not native to your area, or that have different climatic and ecological conditions. This method is also suitable for orchids that have small and non-viable seeds, such as phalaenopsis, cattleya, or vanda. This method is more controlled and reliable, but it is also more expensive and labor-intensive, as it requires special equipment, materials, and skills.

What are the Tools and Materials for Growing Orchids from Seeds?

The tools and materials for growing orchids from seeds vary depending on the method you choose, but here are some of the most common and essential ones:

  • Orchid seeds: Orchid seeds are the starting point of growing orchids from seeds, and they can be obtained from different sources, such as nurseries, florists, or online shops. However, you should always check the quality and the origin of the orchid seeds before buying them, as orchid seeds can easily be contaminated by bad fungi and bacteria. You should also avoid orchid seeds that are old, dry, or damaged, as they may not germinate or grow well. You can also collect your own orchid seeds, by pollinating your orchid flowers and waiting for the seed pods to develop and mature. However, this may take months or years, depending on the orchid species, and it may not produce the same or desirable results, as orchids can hybridize or mutate easily.
  • Fungus: Fungus is the key component of symbiotic germination, as it helps the orchid seeds to germinate and grow in their natural environment. Fungus can be found in the soil where the orchid seeds are sown, or it can be inoculated into the soil from another source, such as a piece of bark, a leaf, or a root. However, you should always use the right type of fungus for your orchid seeds, as different orchids have different fungal partners, and some orchids may not tolerate or benefit from certain fungi. You should also use fresh and healthy fungus, and avoid fungus that is old, dry, or diseased, as it may harm or inhibit the orchid seeds.
  • Agar: Agar is the main component of asymbiotic germination, as it provides the orchid seeds with a sterile and nutrient-rich medium to grow in an artificial environment. Agar can be bought from specialized gardening supply stores or online, or it can be made at home, by mixing agar powder with water and boiling it. However, you should always use the right type and amount of agar for your orchid seeds, as different orchids have different nutrient and hormone requirements, and some orchids may not grow well or at all in certain agar formulations. You should also use fresh and sterile agar, and avoid agar that is old, contaminated, or expired, as it may harm or inhibit the orchid seeds.
  • Flasks: Flasks are the containers where the orchid seeds are sown and grown, either in soil with fungus, or in agar. Flasks can be made of glass or plastic, and they should have a capacity of about 250 ml. Flasks should also have a narrow neck and a wide mouth, and they should have a lid or a stopper that can seal them tightly. Flasks should also be transparent or translucent, so that light can reach the orchid seeds. However, you should always sterilize the flasks before using them, by boiling them in water, or by soaking them in bleach or alcohol, to kill any bacteria or spores that could harm the orchid seeds.
  • Other tools and materials: Other tools and materials that you may need for growing orchids from seeds include:
    • A pot or a tray, where you can sow the orchid seeds in soil with fungus, for symbiotic germination.
    • A pan or a pot, where you can cook the agar, for asymbiotic germination.
    • A whisk or a spoon, where you can stir the agar, for asymbiotic germination.
    • A funnel or a pipette, where you can pour the agar into the flasks, for asymbiotic germination.
    • A knife or a scissors, where you can cut the orchid seed pods or the orchid seedlings, for harvesting or transplanting.
    • A spray bottle or a syringe, where you can water the orchid seedlings, for maintaining or transplanting.
    • A label or a marker, where you can write the orchid name and date, for identifying or tracking.

What are the Steps and Tips for Growing Orchids from Seeds?

The steps and tips for growing orchids from seeds vary depending on the method you choose, but here are some general guidelines:

  • Symbiotic germination:
    • Step 1: Pollinate your orchid flowers and wait for the seed pods to develop. This may take months or years, depending on the orchid species. You can also buy or collect orchid seed pods from other sources, but make sure they are fresh and healthy.
    • Step 2: Sterilize your tools and materials, such as the pot, the soil, the fungus, the knife, and the label, by boiling them in water, or by soaking them in bleach or alcohol, for at least 10 minutes. This will kill any bacteria or spores that could harm the orchid seeds.
    • Step 3: Prepare your pot and soil, by filling the pot with a well-drained and slightly acidic soil, such as peat moss, perlite, or vermiculite. You can also add some organic matter, such as leaf mold, compost, or bark, to improve the soil quality and fertility. You can also add some fungus, either by mixing it with the soil, or by placing it on top of the soil, to create a symbiotic relationship with the orchid seeds.
    • Step 4: Sow your orchid seeds, by cutting the seed pods open with a sterilized knife, and sprinkling the seeds lightly over the soil. You can also shake the seed pods gently over the soil, to release the seeds. You can also cover the seeds with a thin layer of soil or fungus, to protect them from drying out or being washed away. You can also label the pot with the orchid name and date, to identify and track the orchid seeds.
    • Step 5: Place your pot in a suitable location, where it can receive bright but indirect light, such as near a window or under a lamp. You can also place your pot in a humid and warm environment, such as a greenhouse or a terrarium, to create a favorable condition for the orchid seeds. You can also water your pot regularly, but sparingly, to keep the soil moist but not soggy, such as by misting it with a spray bottle or a syringe. You can also fertilize your pot occasionally, but lightly, to provide some nutrients to the orchid seeds, such as by using a diluted or orchid-specific fertilizer.
    • Step 6: Wait for your orchid seeds to germinate and grow. This may take months or years, depending on the orchid species and the environmental conditions. You can check the progress of your orchid seeds by looking for signs of germination, such as tiny green specks or shoots on the soil surface. You can also check the progress of your orchid seeds by looking for signs of growth, such as small leaves, roots, or pseudobulbs on the orchid seedlings.
    • Step 7: Transplant your orchid seedlings when they are big enough to handle, or when they outgrow their pot. This may take months or years, depending on the orchid species and the growth rate. You can transplant your orchid seedlings by carefully removing them from the pot, and gently separating them from the soil and the fungus. You can also transplant your orchid seedlings by choosing a suitable pot and potting medium, such as bark, moss, or perlite, and placing them in the center. You can also transplant your orchid seedlings by watering and fertilizing them well, and placing them in a suitable location, where they can receive adequate light, temperature, and humidity.

Asymbiotic germination

  • Step 1: Sterilize your tools and materials, such as the pan, the agar, the flasks, the funnel, and the label, by boiling them in water, or by soaking them in bleach or alcohol, for at least 10 minutes. This will kill any bacteria or spores that could harm the orchid seeds.
  • Step 2: Prepare your agar, by mixing the agar powder with water in a pan, and bringing it to a boil. You can also add some sugar, minerals, and hormones, according to the orchid species and the agar formulation. You can also stir the agar with a whisk or a spoon, to dissolve the ingredients and prevent lumps. You can also let the agar cool slightly, but not too much, as it will solidify.
  • Step 3: Sow your orchid seeds, by pouring the agar into the flasks, using a funnel or a pipette. You can also fill the flasks about half or three-quarters full, leaving some space for the orchid seeds and the air. You can also sprinkle the orchid seeds lightly over the agar, using a sterilized knife or a scissors. You can also label the flasks with the orchid name and date, to identify and track the orchid seeds.
  • Step 4: Place your flasks in a suitable location, where they can receive bright but indirect light, such as near a window or under a lamp. You can also place your flasks in a humid and warm environment, such as a greenhouse or a terrarium, to create a favorable condition for the orchid seeds. You can also seal the flasks tightly, with a lid or a stopper, to prevent contamination or evaporation. You can also avoid moving or shaking the flasks, to prevent disturbing the orchid seeds or the agar.
  • Step 5: Wait for your orchid seeds to germinate and grow. This may take weeks or months, depending on the orchid species and the environmental conditions. You can check the progress of your orchid seeds by looking for signs of germination, such as tiny green specks or shoots on the agar surface. You can also check the progress of your orchid seeds by looking for signs of growth, such as small leaves, roots, or pseudobulbs on the orchid seedlings.
  • Step 6: Transplant your orchid seedlings when they are big enough to handle, or when they fill the flasks. This may take weeks or months, depending on the orchid species and the growth rate. You can transplant your orchid seedlings by carefully opening the flasks, and gently removing them from the agar. You can also transplant your orchid seedlings by choosing a suitable pot and potting medium, such as bark, moss, or perlite, and placing them in the center. You can also transplant your orchid seedlings by watering and fertilizing them well, and placing them in a suitable location, where they can receive adequate light, temperature, and humidity.

Frequently Asked Questions about Growing Orchids from Seeds

Here are some of the most frequently asked questions about growing orchids from seeds and their answers:

Why are orchid seeds so small and hard to germinate?

Orchid seeds are so small and hard to germinate because they have evolved to disperse and survive in their natural environment, where they face many challenges and competitors. Orchid seeds are so small that they can be carried by the wind or the water, and reach distant and diverse habitats. However, orchid seeds are also so small that they have very little or no endosperm, which is the part of the seed that provides food and energy for the embryo. Therefore, orchid seeds need a fungus to germinate and grow, as the fungus can supply the orchid seeds with the nutrients and the water they need.

How long does it take to grow orchids from seeds?

The time it takes to grow orchids from seeds depends on the orchid species and the environmental conditions, but generally, it can take anywhere from a few months to a few years. Orchid seeds can take weeks or months to germinate, depending on the type and the quality of the seed, the type and the strength of the fungus or the agar, and the light, temperature, and humidity levels. Orchid seedlings can take months or years to grow, depending on the type and the size of the orchid, the type and the quality of the potting medium, and the light, temperature, and humidity levels. Orchid plants can take months or years to bloom, depending on the type and the age of the orchid, the type and the amount of the fertilizer, and the light, temperature, and humidity levels.

How to increase the success rate of growing orchids from seeds?

The best way to increase the success rate of growing orchids from seeds is to follow the instructions and recommendations of the orchid species and the germination method, and to provide the optimal care and conditions for the orchid seeds and seedlings. However, some general tips that can help you increase the success rate of growing orchids from seeds are:

  • Use fresh and healthy orchid seeds, and avoid old, dry, or damaged ones.
