The Soil you choose will not only affect how it looks and grows, but it may be the thing that ends up killing your precious orchid.

Finding the best soil for the Orchid cactus has always been a challenge. There are so many choices from Miracle grow to potting soil. I decided to test some of the top brands to find out which one you should use.

Some Ideas

How to Know If Your Orchid Is an Epiphyte, Lithophyte, or Terrestrial?

Different species of orchids surely require different potting mixes. Both epiphytes, as well as lithophytes, will prefer a mix that will give more structural support and better drainage.

In contrast, terrestrials are the general houseplant. If you aren’t sure which kind of orchid you own, a look to the fundamental anatomy of the plant will possibly give you a few ideas.

The parts of epiphyte and lithophytes have a lot in common. They both have fleshy and thick roots that are able to absorb water as well as some substances from the atmosphere. These plants also are characterized by succulent, succulent-looking stems known as pseudobulbs which serve to store water and aid them through dry times.

However, terrestrial orchids will generally have below-ground tubers and corms, not pseudobulbs. The orchid roots also seem to be longer.

How to Make a Substrate for Orchids – Easy Recipes

Before you prepare your mix with substrates or soil suitable for orchids, it is important to determine whether your orchids are epiphytic, semi-terrestrial, or terrestrial plants as they have different features and components. Based on the type of orchid and species, here’s how you prepare your soil for orchids :

How to Make a Substrate for Epiphytic Orchids

For this orchid, it’s best to create an orchid-friendly substrate made of these elements:

  • Three different parts of the pine bark (if feasible, Mediterranean pine bark).
  • Three cork pieces.
  • A component comprised of white peat.
  • The final component of clay granules or ceramics.
  • 2 g of acid limestone per liter of the substrate.

The cork and pine bark are the foundation of the substrate. they aid in giving the mixture a pH that is adjusted by the acid lime. White peat serves the task of storing water and giving the plant the humidity it requires to maintain its humidity as well as allowing the substrate becomes more well-ventilated.

Substrate for Terrestrial or Semi-terrestrial Orchids

In this case, use this orchid substrate or soil materials:

  • Five parts of pine bark.
  • A part of white peat.
  • A part of charcoal.
  • A part of vermiculite.
  • 2 grams of acid lime per liter.

The major difference with the substrate used for epiphytic orchids is that we include more pine bark and take out the cork and we also add charcoal to boost the pH that the substrate has. Vermiculite assists us in ensuring that the mix retains its beneficial salts.

In both instances, once you have the correct proportions of each substance the only thing you need to do is combine it all until it is all filled in the pot.

If you’re not certain about the kind of plant you have,  then we suggest seeking help from an expert from a nearby garden store and showing them your orchid.

What are the Best Pots for Orchids and How to Prepare them?

There is a belief that orchids require containers that are transparent because they are able to photosynthesize via their roots. True that a transparent pot can assist us in taking better treatment of our orchids but not since the orchid is able to perform photosynthesis through its roots, which is completely false. The reason is that in these orchids it is very crucial to regulate the health that their root systems in particular when they are deciding the right time you should water orchids.

If the roots are green, it means that the plant has enough water. However, if they become whitish It is an indication that you have to take care to water them. Certain species are especially susceptible to these variations in humidity, such as the case of Phalaenopsis and the most typical is to find the plants within transparent containers.

Furthermore, It is important that the pot where the orchid will be placed has an elongated rim or legs that elevate the pot above the ground so that the plant is not directly in touch with water that drains from the holes for drainage. the excess moisture could cause waterlogging and can cause damage to the plant.

Epiphytic orchids, could also significantly benefit from using hanging baskets. They allow their aerial roots to be able to drain, which aids in helping the plant to better absorb moisture that it requires from the air, and thus improve its growth. Actually, there is an option to not need any basket and just hang the plant on the stem. This gives it an extremely striking and bold appearance.

When and How to Transplant Orchids

These plants need periodic transplants to grow properly. In fact, it is advisable to carry out the transplant every 2 years, between the end of winter and the beginning of spring, before the plant activates its rhythms.

In the case of transplanting epiphytic orchids, follow these steps:

  1. Prepare a new pot with a suitable substrate, filling it up to just over half.
  2. Water the pot with plenty of water 2 hours before transplanting.
  3. Extract the plant very carefully and take advantage of the moisture in the substrate to remove it from the roots more easily, paying special attention not to damage them.
  4. Plant the orchid in the new pot, add the rest of the orchid substrate, and water the plant.

If it is terrestrial orchids, follow the usual steps for a transplant but keep in mind that you do not need to moisten the plant so much before transplanting. Just be careful with the roots so as not to damage them.

Orchid Cactus Care

The care of this beautiful cactus is as follows:

  • We must put our plants where they can get plenty of sunlight. It can also live in a shaded place as long as there is lots of light.
  • If we purchase it in the summer, we’ll not transplant it until the spring arrives to make sure that the plant’s blooms are in the right place.
  • It needs special soil so that it can grow. The soil should let the water drain out.  We will make the following mixture: 60% sand and 40% peat. We will mix sand and peat in different ways depending on how much water falls from the sky in our area and on how much sun is shining where we live.
  • We will always water letting the substrate dry between watering and watering.
  • During the growing season, we can make it grow healthy by giving it fertilizer. You can fertilize the plant by adding organic fertilizer or slow-release fertilizer to the ground when you water it.

Epiphyllum is easily reproduced through cuttings in the summer. We’ll cut the leaves to at least 20cm long and then plant them in a pot using the substrate mix previously mentioned. Within a few weeks, they will be rooted and we will have new specimens.
