Rules for planting orchids in a closed system

The method of growing orchids in a closed system is becoming increasingly popular due to its simplicity and effectiveness. Planting an orchid in a closed system is that the flower is planted in a container without holes, and water is poured into the bottom of the pot.

Rules for planting orchids in a closed system

Growing principle

When phalaenopsis is contained in a closed system, the influence of the external environment is reduced. The method has been carefully described by florist Yulia Aksenova, and Olga Kovalenko even lands in a tank for aquariums.

The method is suitable for dry climates. A plant planted for this principle remains moist. The roots will stretch down, which will ensure the integrity and growth of the root system - this contributes to the rapid growth of leaves and peduncles.

Orchid cultivation in a closed container concerns only the roots, the terrestrial part of the plant develops under ordinary conditions. A flower planted by this method requires less attention.

Advantages of the method:

  • culture blooms for a long time;
  • the root begins to grow faster;
  • creates a natural living environment.

Cons of growing: decay of the root neck, which will lead to the death of the plant, and a high level of humidity.


Planting is carried out not only for growing, but also for resuscitation of a flower for a certain period.

The flower should be:

  • healthy, without signs of disease;
  • with a strong root system;
  • with well developed leaves.

Planting also helps save a diseased tree that has lost its root system as a result of decay. After placing the leafless culture in a tight pot, it comes to life. The flower grows roots and begins to bloom.

Capacity selection

A glass container is suitable as a pot. It is more stable and has a beautiful appearance, in comparison with a plastic container. Glass does not have a porous structure, so the roots of the plant do not grow.

Choosing a transparent vessel, it is easier:

  • control the water level;
  • observe the growth of roots;
  • see the general condition of the plant.

The shape is chosen even or with edges expanding upwards, so as not to damage the root system during transplantation.

Children and small orchids are placed in various containers:

  • wineglass;
  • cache-pot;
  • beer mugs;
  • glass;
  • small aquarium.

For large plants, choose a volumetric pot. A plastic container is used only as a temporary vessel for transplantation. You can make holes in it at any time if the growing method is not suitable.

The main components of the substrate

The substrate for orchids in a closed growing system consists of certain components that cannot be mixed. They are laid in layers.

The composition of the substrate:

  • sphagnum moss;
  • expanded clay;
  • pine bark;
  • charcoal.

Pieces of bark are made 1-3 cm in length so that moist air passes freely between the pieces. This will get rid of mold during cultivation. Cones can be an analogue of the bark.

Sphagnum moss has disinfectant and antibacterial properties, so it does not need to be processed, like other components. It is recommended to collect it yourself, or when buying, choose moss where there are small green branches.

Such a substrate keeps the root intact and protects from decay.

Landing process

We comply with all recommendations for landing

Phalaenopsis in a closed system is grown according to the following rules:

  1. The container is treated with boiling water for disinfection or sterilized.
  2. Expanded clay is poured into the bottom with the first layer, which should be placed about ¼ of the pot, this is about 3 cm.
  3. Sphagnum moss is laid in a layer up to 0.5 cm.
  4. The remaining space is filled with bark and charcoal.
  5. The substrate is poured with settled warm water and left for half an hour.
  6. The remaining liquid is drained and a flower is planted. Top with a little moss, as mulch.

The roots should not reach the expanded clay with water. After the action, the pot is placed in a permanent place.


Orchid care consists of transplanting (if necessary), watering and proper top dressing.


A plant may need a transplant if the root system does not fit in the pot. The plant is transplanted in the phase of intensive growth (so the orchid will tolerate stress more easily). The bush is transplanted with a small amount of soil on the roots, but pruning dry or rotten ends.

Top dressing

They feed the flower in a closed system with less intensity. Use standard fertilizers for orchids:

  • "Kemira Lux";
  • "BonaForte";
  • "Cameleon".

Dosage is reduced 10 times from the instructions.

For feeding use only mineral solutions. Fertilize should not be during flowering, within 10 days after transplantation, in hot weather.

Feeding methods:

  • make in dissolved form;
  • sprayed on the green mass and the visible root system;
  • added to water intended for irrigation.

Fertilizers must contain, in addition to nitrogen, phosphorus and potassium, also manganese, magnesium and boron. Trace elements enhance the immunity of the flower.

Features of watering

Orchid, gaining access to moisture, begins to grow faster. Therefore, the amount of water and the regularity of watering is an important stage of care. Expanded clay should always be wet - this allows the plant to draw moisture from the bottom of the substrate.

To determine when to water the flower, look for the presence of condensation drops on the inside of the container. If they are, then watering is not required.

A guideline for adding water is the color of the root. If it is green - the substrate is moist, light gray - the plant requires watering.

Water the flower with a watering can on the inner wall of the container to the level of expanded clay. It is also possible to immerse the pot in a container of water for 20 minutes. The main thing is to adjust the frequency of watering according to the microclimate in the apartment.

Diseases and Pests

Wet substrate like midges. The best insect repellent is dry mustard powder, which is sprinkled on top of the substrate.

If thrips and scabs are found on the flower, treat it with one of the solutions (reducing the dosage):

  • "Aktara";
  • "Actellik";
  • Fitoverm.

The processing interval is 10 days, the number of sprayings is 3-4.

If root rot and blackening of the leaves is observed, this is a sign of powdery mildew, anthracnose, or leaf spotting. Such a plant is not treatable.

When only the root rots, it is urgently removed from the substrate, washed with water, the decayed parts are cut off and dried for 4 days. Then completely change the substrate in the container and plant the flower back.


Growing a phalaenopsis orchid in a closed system allows it to effectively develop in any conditions. With proper care and compliance with all the rules, you can get a healthy and beautiful plant.
