Soil for orchids

Owners of their own backyard plots often cannot decide on the choice of the most optimal soil before planting such a capricious ornamental plant like an orchid. Finding a suitable mixture for growing a particular variety does not always work, so summer residents and gardeners have to experiment and sometimes make mistakes and blunders.

All varieties of orchids are divided into several groups, which are called epiphytic and terrestrial. The first of them can attach to the surface of stones or other plants. Their root system is located not in the ground, but in the air, from which it receives the necessary moisture. As a result, the use of a substrate is not required for the cultivation of epiphytes. Land orchids are very different and grow in completely different conditions. They grow among the undergrowth in loose and fertile soil.

If you decide to start growing orchids - this demanding flower, then the ideal soil will be a ready-made mixture that is intended specifically for these plants. However, it is better to purchase it in specialized garden stores, where soil for various varieties is sold. Mixtures for specific species, for example, phalaenopsis, are also on sale. Although only one flower is named on the package, it can be used to grow all epiphytic varieties.

Components of soil for orchids

The mixture of soil must be chosen depending on the height of the shrub and the volume of the container where the flower will grow. As a rule, moisture-retaining components should be the main part of it if the plant is to be grown in a basket or in a separate block. However, mature shrubs that are planted in pots do not really need these materials.

Sometimes there are varieties of orchids that need the presence of heavy soil for full development. Natural and artificial components with their own characteristics can be in it in different proportions. These types of orchids include, for example, cymbidium.

Natural ingredients

  • tree bark
  • sphangnum moss
  • fern roots
  • peat
  • coconut substrate
  • charcoal
  • Pine cones
  • leaf land

The collection of bark is carried out in the forest from sawn or fallen pine trees. Sometimes dry peeled bark is used, which is carefully removed from still growing trees. It is not allowed to collect rotten pieces of bark, since they contain a large number of pathogens that can harm the plant.

The sphagnum moss, which is used to fill the pot, acts as an antiseptic and a component that retains moisture. It is used to prevent the risk of soil drying out, for example in nets, blocks or other containers where air circulation is present. Good quality moss is usually collected from swampy areas or forests. Before using this component for growing an orchid, it must be ventilated and dried. In ordinary flower pots or containers, which have continuous walls and holes for water to drain, moss may not be used. Adding filler on top of the soil will suffice.

There are varieties of orchids that grow well only in sphagnum, since moss really has all the beneficial substances. However, you still need to follow the rules for caring for the plant in order to avoid a lack or excess of moisture.

Fern roots are dug out in the forest, then they are cleared of the ground and thoroughly washed in water. Cut clean and dried roots into pieces no more than 2 cm long.

Charcoal is used to maintain a constant level of acidity in soil and water. It should be included in the soil mixture in moderation, since it tends to accumulate salts and, thereby, affect the overall salt balance. For plants that need regular feeding, it is required to use charcoal in the soil in small doses. It is also pre-washed and dried, and then crushed into tiny pieces. Prepared coal is applied directly to the soil or sprinkled on the soil surface in a container for growing an orchid.

Another component that collects moisture is peat, which is characterized by a strong coarse fiber base and a low salt content. It does not need to be crushed.

Pine cones are cleaned of seeds and other foreign debris and washed with water, after which the scales are separated from each other. Then they are dipped in boiling water for several minutes for disinfection, and then dried. Pine cones can be used instead of bark. The fragile scales of spruce cones are not suitable for this purpose.

Leaf soil, after removing leaves and small twigs, is used as a common garden substrate, which is added to ready-made mixtures for growing cymbidium.

Artificial components

  • perlite
  • expanded clay
  • vermiculite

Perlite and vermiculite have the property of imparting looseness to the soil mixture. When released into water, they swell and then regain their previous appearance, releasing dissolved nutrients.

The bottom of the container is covered with expanded clay. It is a drainage material that can absorb accumulated moisture.

Soil for growing epiphytes

The substrate used to grow epiphytic orchid varieties does more than just a nutritious function. Its main role is to keep the shrub upright and provide air to the roots. For this reason, such a substrate may not contain any loosening components or soil, but only consist of bark, coal or coarse sand.

It is not necessary to add all of the listed components at the same time. Most epiphytic orchids develop fully when grown in a mixture of charcoal, bark, sphagnum and fern roots, which are taken in the same ratio. However, such conditions are suitable only for those specimens that will grow in nets or blocks with free air circulation. The use of moss in such mixtures is mandatory in order to retain the required amount of moisture and protect the orchid from drying out. Sphagnum helps determine if it needs watering.

A mixture for potted orchids should contain one part charcoal and five parts pine bark. Such a composition is characterized by a low level of moisture content and the ability to pass air. For indoor varieties grown in baskets or blocks, it is required to use a substrate that retains moisture for a long time, which should include coal, moss, and pine bark. They are added in a ratio of 1: 2: 5.

Soil for growing terrestrial orchids

Land orchids need to be fed regularly. Growing them requires a mixture of charcoal, peat, pine bark and leafy soil.

An epiphytic substrate is often used, to which dry sphagnum is additionally added, which retains moisture, and garden soil.

In the absence of a ready-made mixture, bark, coal, moss and peat are poured into the pot in a strict sequence to increase fertility. However, it must be added sparingly so as not to weigh down the soil, otherwise the roots can easily rot. The components are carefully mixed, expanded clay is poured onto the bottom of the pot.

Due to the fact that during the entire period of its life various root excretions gradually occur in the plant, the substrate is destroyed over time and turns into unusable dust. This is also influenced by the presence of bacteria and fungi, which accelerate the decomposition of organic components in the mixture. In this regard, the substrate becomes unsuitable for growing an orchid. Air circulation inside the pot is also disrupted, which has a negative effect on the development of the plant's root system. If you notice any warning signs, then it is better to transplant the flower into a new substrate or change the soil in this growing container.

Completely ready-made soils of the Effect + trademark for orchids, as well as for growing flower and ornamental crops requiring high air permeability - epiphytes and aroids, in particular, it is very effective for transplanting orchids: phalaenopsis, dendrobium, cattleya, cymbidium, etc.

The soil of the Effect + trade mark is made on the basis of selected calibrated pine bark. Thanks to the selected calibrated bark, the soil is light and airy, resistant to caking, which is a prerequisite for the development and growth of sensitive aerial roots of orchids. The very shell of a tree of any species is a complex complex of fabrics. This is not easy hardened wood, it is a multilayer coating with a complex chemical composition. The wood contains lignin, which stimulates growth and flowering. Nitrogen, oxygen, natural wax and ash are important for plants. All of them are already in the bark. Therefore, it is no longer necessary to add fertile soil to a properly prepared bark. This material contains everything necessary for the active nutrition of the plant.

  • optimal conditions for plant growth and development
  • perfect balance of air and water
  • stable soil structure
  • open and closed growing system
  • easy root control
  • without pests and decay of the root system.
  • Effect + orchid primer consists of a complex of components that maintain an excellent balance of air and moisture, and is ideal for most popular species and hybrids of mini orchids - adults, dwarf, young and children of the family orchid (Orchidaceae) and other epiphytic plants.
Foam glass GrowPlant works as a drainage - dry fractions quickly absorb moisture, and then slowly release it. Provides protection against bacteria and fungi, plants do not rot, develop intensively, because their roots receive an optimal ratio of moisture, oxygen and nutrients. Since GrowPlant Foam Glass is made of recycled glass, silicon is washed out from its surface in a form that can be absorbed by the plant - monosilicic acid (H4SiO4). Plants that accumulate silicon:

a) have a higher stress resistance

b) silicon stimulates growth and abundant flowering

Effect + ready-made soils for orchids can be used alone or serve as a basis for the preparation of professional substrates. Optionally, depending on the group and type of plant, you can add other components to the Effect + soil composition - charcoal, moor peat, coconut chips and other substrate components of the BIOABSOLUT line of our production.

ZEOLITE is a natural mineral with unique propertiesthat promote plant growth. Porous, moisture-absorbing, sterile - provides ventilation of the root system and a supply of the required amount of water without overmoistening the roots of the plant, available silicon stimulates plant growth and active flowering. The ability to use any containers, containers, pots, including plastic and glass (open and closed growing system).

Mass fraction of nutrients:

ü Nitrogen (N) soluble (CaCL2) 50-250mg / l

ü Phosphorus (P2O5) soluble (CAL) 80-250 mg / l

ü Potassium (K2O) soluble (CAL) 100-350 mg / l

For their development, orchids need not only moisture, but also many useful microelements, which in the natural environment they take mainly from accumulations of humus in the cracks between the bark. Especially a lot of nutritious humus is collected in the depressions of the bark of the branches, it is there that orchids purposefully pull their "air" roots to get to the most nutritious place. Observing the growth of the root system of epiphytic orchids, it can be noted that plants sitting in a nutritious place have a very meager root system and are reluctant to pull out long "aerial" roots.

Orchids, subject to certain care rules, can delight with an aesthetic appearance and long flowering periods.

What should be an orchid pot

When you have decided what kind of soil will be used, you need to choose a container. For an apartment or house, plastic or clay pots are suitable. In which of the two pot options to plant a flower, each grower decides on his own. The selected pot must have holes in the bottom.

Plastic pot

It is believed to be best when the flower is planted in a plastic pot with transparent sides. Through the transparent walls, it is easy to monitor the condition of the rhizome and determine the degree of soil moisture. Such a pot transmits light well. The disadvantage of the container is its unattractive appearance.

Clay pot

The clay pot, being made of natural material, is moisture and air permeable. It is chosen for growing varieties that love cool climates. The clay container is heavy, so the plant will not fall off the windowsill.

The main disadvantage of such containers is their roughness. Also, roots can grow to the walls of the pot, which will lead to injury during transplantation. It is worth noting that the soil in earthenware will dry out faster.

The diameter of the container is selected in accordance with the dimensions of the root system of the flower.

To plant an orchid in an apartment, it is necessary to select the right soil and pot for it. You only need to transplant an orchid in the right soil and container!

Substrate preparation

How to prepare it at home for an orchid? To create suitable conditions for flower cultivation, you need compose a substrate from the elements necessary for it... Otherwise, the flower may not take root in a new place.

All elements of the substrate are divided into inorganic and organic.

  • Inorganic:
    • Perlite and vermiculite - These are mineral components that are added to the soil for orchids. They will not give any nutrients to the flower, but will help it cope with rot and mold. In addition, they loosen the soil well.
    • Expanded clay - a necessary component, which is placed on the bottom of the pot in a 3 cm layer. This function can be handled by:
      • Styrofoam
      • Polystyrene.
  • Organic:
    • Bark - rip it off from such trees:
      • Pine
      • Oak
      • Larch.
    • Charcoal - it can be collected after the fire, or you can buy it in the store in the department where the components for going out into nature are sold. It is also available as part of purchased soils and you can select it from there.
    • Fern root - it can be dug up in the forest area in the summer. If possible, short pieces
    • Sphagnum moss - it is collected in the forest in swampy areas or along rivers and reservoirs, where there is high humidity.

All soil components can be purchased in a shop specializing in soil, in garden centers. The price of the components, depending on the packaging and the region of sale, is in the range of 100-250 rubles.

Basic recipes

How to make your own orchid substrate? All types of these plants require a soil that will suit them. Most gardeners do not collect the soil themselves, but purchase in respective stores... It's easier this way, and the soil will be of the required quality. It should be noted that the plant only needs natural soil components.

How to make the right substrate at home? Now you can make the soil based on natural ingredients:

    Recipe 1. Mix coal and bark in a 1/5 ratio. This soil will be non-moisture-absorbing and well-permeable to air.

There are many recipes for preparing orchid soil.

Composing the substrate yourself, you need to pay attention to the fact that all components do not have a putrid odor. But even though everything looks great on the outside, the soil must be sterilized.

To do this, place the made substrate in the freezer of the refrigerator and leave it for 15 hours. This will help us get rid of harmful insects and their larvae.


How to prepare the soil with your own hands? If you decide to compose the soil yourself, but there are no necessary components on sale, then you need to go to the forest and look for the necessary components... Having typed the source material, you need to carefully examine it so that there are no rotten places there:

  • Bark needs remove tar and dirt and cut into fractions 1x1 cm. and larger 2x3 cm.To disinfect the bark, it can be kept in a water bath or frozen in the freezer of the refrigerator, after steaming the bark must be well dried
  • Sphagnum moss we cleanse from accompanying impurities (foliage and small sticks), dry and cut into strips of 10 cm
  • We take coal from the fire only if they were not watered with ignition mixture bonfires.

Then all the components mixed in those proportionsthat are necessary for a particular type of orchid.

The components are put in the proportions that are necessary for a particular type of orchid. So, Phalaenopsis needs a soil without nitrogen additives with good aeration. Dendrobium grows in more nutritious soil.

The necessary acidity of the substrate for orchids will give bark and coal... In order not to increase it, it is necessary to put coal in small proportions, since it serves as an oxidizing agent for the substrate. The acidity should be between 5-7 pH.

Substrate must be breathable and, at the same time, keep the flower in the growing pot. After planting an orchid in a new soil, it needs care.

How to make a substrate with your own hands?

In order to make the composition with your own hands, first of all, you need to find out what substrate is required for a particular type of orchid and decide on how it will be grown.

  1. Mesh containers and blocks. For most epiphytes, a composition is suitable, which includes: pine (oak) bark, sphagnum and charcoal in equal proportions.
  2. Drainage pots and bark containers. Bark mixed with charcoal is suitable as a basis for them. The top of the planting must be laid out with moss.

Let's take a closer look at how to prepare soil for orchids with our own hands.
Depending on the substrate with what moisture content is required for a particular type of plant, additional moisture-intensive components can be added to these compositions.

For example, to compose the soil for an orchid with your own hands, you can use the following components:

  • epiphytic species: pine (oak) bark - 3 parts cork bark - 3 parts, peat - 1 part, moss - 1 part, expanded clay - 1 part
  • terrestrial species: pine (oak) bark, peat - 1 part, moss - 1 part, expanded clay - 1 part, charcoal - 1 part.

Substrate treatment

How and why to sterilize and rinse?

It can contain harmful microorganisms and bacteria.

Unscrupulous manufacturers, if stored improperly, can allow fungal diseases in components.

If you pick it yourself, you can also harvest the same bark stuffed with pests.

For disinfection it is customary to expose it:

  • Heat treatment
  • Boiling method
  • Watering with boiling water
  • Firing in the oven.

After heat treatment is carried out soaking in cold water, and then complete drying.

How to disinfect?

Some experienced orchid growers recommend treating with a solution of furacilin or potassium permanganate.

Basically, a good heat treatment is enough to protect the plant from harmful microorganisms and pests.

Plus, the moss itself is a good antiseptic.
