Once you find a good mix, taking care of your orchids is pretty simple, and all you will have to do is water it from time to time.

This orchid bloom booster is a product made specifically for orchids that are grown as houseplants in different types of pots or containers.

Since it has high phosphorus levels, it will help your orchids glow even in the places with the lowest light without any problems.

However, I recommend keeping your flower in a place facing south so it can get at least some sunlight every day because it will make it blooming a lot faster, and its color will definitely be way more beautiful.

It is also one of the special orchid potting mixes, so I believe you won’t have much success if you try using it on other plants.

Users claim that this is one of the best products for orchids and that it gives results immediately, so if you are eager to enrich your living space with this flower, this is the best thing you can buy.

You can also use it if you want to repot an orchid or to help recover mature orchids that have lost their vibrant color.

It is rich in organic matter, and all potting materials used in this product are 100% organic and natural, including wood chips, sponge rock, and lava rock.

The mix also has a great pH balance that should stay consistent during the time, but I still recommend checking it out from time to time, just to be sure everything is fine.

All chips will have a consistent size, and they will be able to absorb water well and provide your plant with enough fresh air.

It has a great advantage that not only is it able to get wet easily, but it also dries out in a very short period of time.

This is one of the most affordable orchid mixes on the market, and in my opinion, it is among the best ones you can find.

When reporting with this mix, every orchid mother plant will stay nurtured and healthy, while you will also get a lot more of these beautiful flowers.

However, users claim that this bark worked perfectly for many other plants like hydrangeas, so it is definitely multi-purpose.

Key features

This pine bark potting mix is 100% natural and organic, and it is rich in wood bark that is harvested from forests of New Zealand.

However, people complain that the one that comes in a small size is the only one that is good and that the products you receive when you buy M or L have completely different ingredients and give different results.

For that reason, I recommend buying a small-sized one from your local store and sticking with it if it turns out to be good.

  • Organic and natural
  • Simple ingredients
  • Affordable
  • Great drainage capabilities
  • It can be used for many different houseplants
  • Not all bags of this product are completely the same

Things to Consider When Buying Best Soil for Orchids

Fir bark

Orchids love organic environments, and you will for sure need to plant them in almost 100% organic soil if you want them to thrive.

However, even though most organic soils are based on peat moss or sphagnum peat moss, the one that will provide you with the best results and help your plant thrive is the one that is based on fir bark.

This is the most nutritive organic ingredient, and it works amazingly in combination with orchids, so I recommend looking for potting soil or making your own one that is based on it.


Orchids need a lot of water in order to be able to grow healthy, but they can’t really succeed in an environment that is too wet.

For that reason, you need soil that will keep the water that this plant needs and eliminate all the excess water that may lead to root rot or wet feet.

What is the best potting mix for orchids?

There are different types of orchids, but most of them will enjoy soil that is based on peat moss or sphagnum peat moss.

An organic soil rich in perlite, vermiculite, coconut coir, and fiber will create the perfect blend that will help your orchids thrive.

Do I need special soil for orchids?

Orchids that are used as houseplants planted in different types of containers or plants require special soil that will be enriched with different ingredients and fertilizer.

Unlike terrestrial orchids, those grown as houseplants will eventually die if they are repotted in regular organic soil that is not accustomed to their needs.

What soil do you use to repot orchids?

When repotting orchids, you want to make sure you mimic their native soil well, so it is best to grow them in soil that is peat moss or sphagnum moss based.

You should keep them in soil that is a mix of special orchid compost, some type of peat moss, perlite, and pine or fir bark fines.

Can I use multi-purpose soil for orchids?

Multi-purpose soils will rarely do the job for your orchids because they are usually oversaturated with different organic ingredients and fertilizer that will completely stop your orchid’s roots from developing and getting enough air.

Orchids need good aeration, and they can rarely succeed in multi-purpose soils because they can’t be accustomed to the flower’s needs.
