Are Organic Potting Soils Suitable for Orchids?

When it comes to orchids, the benefits of organic potting soil are undeniable. Orchids thrive in a well-draining medium that allows air circulation to their delicate roots. Organic potting soils provide just that, ensuring proper moisture retention without waterlogged conditions. With its diverse mix of natural ingredients, organic potting soil also supplies essential nutrients for healthy growth, making it a suitable choice for flourishing orchids.

Orchid Care Tips

Water It Just Before It Becomes Dry

One of the most common reasons why orchids die is because they get overwatered.  A simple way to find out if your orchid needs water is to put your fingers in the orchid soil mix.  You will easily be able to tell if there is any moisture in the soil.  If you don’t feel any moisture, then it is time to water it.  There is a fine line between watering and watering too much, so be careful to not overwater.

Get the Correct Orchid Potting Mix

As I mentioned throughout this article, make sure to get the correct orchid potting material.  Make sure the potting mix provides the proper amount drainage, moisture, and air circulation.  The potting medium for orchids is very important, so make sure to choose the right kind.


If you want to keep your orchid in tip-top shape, it is going to need proper nutrition much like a human body.  Fertilize your orchids either weekly or every other week while they are producing new growth.  Once the plant has matured, decrease adding fertilize to just once a month.  When your orchid goes dormant for the season, stop fertilizing until the next growing season.

Indirect Lighting

Don’t put your orchid in direct sunlight.  Instead place it in an east-facing window.  South and west facing windows will produce too much direct light for an orchid, while north facing windows don’t produce enough light.


It’s a good practice to repot your orchid every other year.  You may even repot it every year if you notice that your orchid has stopped blooming.  If you are considering repotting an orchid after one year, first analyze if the orchid has sufficient lighting, temperature and humidity before repotting.

Check for Illness and Pests

Keep an eye on your orchid and do routine checks for signs of disease or pests. Common orchid pests include aphids, scale and mealybugs.  Insecticidal soaps are good for washing off orchid pests.

Final Thoughts

I’ve gone over some basics for selecting proper orchid potting soil.  There is no perfect best medium potting soil for orchids, though there are some basic needs that you should provide.  In addition to orchid soil, make sure to have the right amount of drainage, moisture and air circulation.  With over 30,000 different types of orchids, individual needs will vary slightly but by following the basics, you should be safe.  I hope that this article on selecting orchid potting mix helps your orchids to thrive so you can enjoy their unique beauty.
