Orchid fans are accustomed to admire this flower, but often experienced flower growers face the difficulties of growing a crop. One of the common troubles that can happen is rotting of the root system. We will tell you how to save the plant from death.

Orchids often rot in the autumn-winter period due to lack of sunlight and lower air temperature. The plant hibernates, and by external signs it is difficult to determine its condition. The leaves remain dense and green, but the roots stop feeding on moisture, resulting in fluid accumulation in the flower pot. If the flower is in a similar condition for a long time, the roots begin to rot from excess water, and the orchid dies.

When viewed from a tropical beauty, pay attention to the following indicators:

  • the state of the leafy part (if the roots have rotted, the leaves become sluggish and quickly turn yellow),
  • condition of escape (if the stem turns yellow from top to bottom - this is a sure sign of ill health),
  • lack of flowering (the damaged rhizome of the plant cannot energize the buds because of its painful state of health),
  • stability (rolling the bush to the side or strong reeling when lifting the pot indicates that the perennial has nothing to hold on to the ground).

If you notice at least one sign from the presented list, immediately release it from the soil to determine the degree of root damage. Live roots differ from the dead by such criteria:

  • color (strong branch has whitish or greenish tint, black or brown color appears on rotten stems),
  • to the touch (a healthy root differs in elasticity, density, and the dead have a hollow texture and are crushed from touch).

Often, members of the Orchid family disappear due to inadequate content and due to the defeat of pathogens. The plant can be saved at home, until it dried out completely. Too abundant watering adversely affects the diet of the culture. Paradoxically, but the roots will not be able to absorb moisture, if the substrate is constantly wet. Soil between irrigation must dry, it is necessary that the sun's rays penetrate it, drying the soil. In the absence of adequate lighting, water will not get to the leaves.

Plant the flower in a pot with transparent walls. Thanks to this, you can monitor the condition of the soil and roots.

Rot causes tight soil. In the fresh loose substrate, which lies loosely in the pot, there are certain nutrient elements. Air gaps allow the roots to absorb oxygen and enrich them with the whole bush. Over time, the soil is compacted and leads to the "suffocation" of the orchid. Therefore, always monitor its condition, it should not sag.

Gentle roots are sensitive to concentrated dressings and their frequency of application. Excessive doses of fertilizer can cause burns and death of root tissue. Use exclusively those fertilizers that are intended for Orchids. Feed up no more than two times in 30 days.

Root death can cause technical damage, for example, during transplantation. If the broken shoots were not treated with special disinfectants, the result of the work done will upset you. The tissues affected by bacteria are not able to supply moisture to the leaf plates, and staying in a moist environment leads to rotting.

How to revive an orchid: available at home ways

The orchid left without roots should not be thrown away. A tropical plant, with due care and patience, proves to be very enduring and life-loving. Experienced growers are advised to consider three ways to revitalize:

  • in the home greenhouse,
  • without a greenhouse, using regular watering and drying,
  • using the landing in the usual substrate.

Before resuscitating an orchid, you need to evaluate its condition and choose the most effective and fastest way possible. If the flower, which has lost less than 60% of the roots, can be restored to health within a month, then the orchid completely devoid of the root system may require special maintenance and care for up to a year.

The choice of how to save an orchid without roots depends on:

  • from the condition of the affected flower,
  • on the number and condition of the leaves,
  • from the presence of the rudiments of horses formed in the lower part of the leaf rosette.

Of considerable importance are the conditions that the florist can create for the reanimation of an orchid without roots.

How to reanimate the orchid in greenhouse conditions?

If the grower has a window greenhouse in which the plant will be kept at a consistently high humidity and a comfortable temperature, there is a high probability of saving even a seriously weakened flower without a root system.

How to reanimate the orchid, if the roots rot? In the container in which the flower is to be rooted:

  • poured a thin layer of expanded clay,
  • on top of it lay a layer of peeled, carefully steamed sphagnum.

The substrate is gently moistened and placed in a sheet rosette. Until the plants form 3–5 cm long roots, the flower will have to be constantly under cover:

  • at air temperature from 22 to 28 ° C,
  • with air humidity in the range of 70–100%,
  • with bright ambient light for 12-14 hours a day.

Temperatures below 20 and above 33 ° C inhibit root growth, but it contributes to the reproduction of pathogenic flora and fungi.

What if orchids have rotted all the roots? Is it possible to stimulate rooting? Yes, this can be done with the help of competent care for the sheet rosette located in the greenhouse. As required, the substrate is slightly moistened, and the greenhouse is aired. It is best to do this at night, which contributes to the saturation of air with carbon dioxide and causes the beginnings of a future healthy root system to form faster.

The success of rooting depends on the observance of the temperature regime, the maintenance of a long daylight day and the increased humidity for the apartment. While the orchid is in the greenhouse, the outlet should be regularly inspected to prevent the occurrence of rotten foci.

In four out of five cases, using this method, you can save the orchid without roots, and signs of the formation of a new root system become visible in 10–14 days. A plant with roots of 3-4 cm length is planted in a normal substrate and transferred to the normal conditions for the flower.
