Secrets of watering indoor and outdoor orchids. How often to moisturize and what mistakes should you avoid?

Orchid is a rather capricious flower and demanding for the conditions in which it is kept, especially for the frequency and intensity of watering.

For this plant, both too frequent and insufficient watering are destructive. Proper care ensures the health, growth and regular flowering of the plant. This article talks about the secrets to watering your indoor and outdoor orchid.

What determines the frequency of watering?

How many times a week to moisturize a flower depends on various factors:

  • season (cold or warm);
  • climate features (presence or absence of temperature extremes, high or low levels of humidity and illumination in the room);
  • features of the soil in which the plant was planted;
  • orchid variety (such varieties as phalaenopsis, miltonia, cymbidium and pafiopedilum love well-moistened soil, and odontoglossum, oncidium, dendrobium and cattleya, on the contrary, prefer dry soil);
  • the size of the plant (a large flower needs to be watered less often, and a smaller one more often);
  • physiological characteristics of the plant (phase of active growth or dormancy).

In order for a flower to be healthy, a combination of these factors must be taken into account.

How to determine if you need to moisturize?

There are clear signs that signal that the plant needs additional moisture:

  • light roots of a whitish or grayish hue (if the roots are green, you need to postpone watering for several days);
  • very dry walls of the pot, there is no condensation on them (this rule applies to plastic containers);
  • a light pot (when the soil is wet, it seems a little heavier).

Florists make sure to test with a wooden stick. (You can also use a long match or a toothpick). It is immersed in the soil for several minutes, and then taken out and analyzed: if it is completely dry, it is time for watering.

Don't rely on just one or two signs. The soil often dries out unevenly, especially if the pot is large, the top layer may already be dry, and a lot of moisture still remains below.

Attention! For beginners in flower cultivation, it is better to purchase transparent pots - it is more convenient in them to assess the degree of moisture in the soil and roots. If you are still unsure of the need for watering, it is best to wait 1-2 days.

How often should you irrigate during the week?

At home

Watering is optimal about 1-2 times for 7-10 days. In the heat of summer and in winter, when the heating devices dry out the air, you can water it 1-3 times a week. In the cool off-season - less often, about once every 10-14 days. We talked about watering in winter and autumn here.

Watering orchids at home is most conveniently organized with the help of a warm shower, by immersing the pot with the plant in water, as well as using an ordinary home watering can with a long and sharp spout. Read everything about moistening an orchid in a pot at home here, and what water is needed for irrigation and what else you can moisten orchids with is described in this material, and here you can read about watering with a watering can and other methods.


If the orchid is growing in the garden, water it more often to keep the soil moderately moist at all times. For a street flower, it is important to organize a good drainage system. You can also use the drip irrigation method.

Important! Do not water the flower when the sun is shining brightly - the leaves can get severe burns.

Thus, it is impossible to establish a clear watering schedule for orchids, because many factors affect its frequency. But some general rules can be distinguished: at least once every 2-3 weeks, but not more often than every 2-3 days.

The frequency of watering the plant


During the flowering period, you need to slightly increase the frequency of watering up to several times a week. At this time, there is no need to wait for the soil to dry completely, since the roots need additional nutrition every day.

Excessive watering should not be allowed - this can lead to rotting and death of new buds. Also, do not use the immersion method every time; it is better to slightly moisten the soil with a watering can.

If the room is very stuffy and hot, you can periodically spray the leaves with a spray bottle, but you need to do this very carefully so that moisture does not get on the flowers.

Not blooming

After the end of the flowering period, you need to sharply reduce the number of waterings. You can even leave the plant alone for about a month to allow the soil and roots to dry out completely.

This tactic of behavior is associated with the natural growth cycle of the orchid. In natural conditions, after the end of flowering, a dormant period begins. This phase coincides with dry weather. At this time, the plant begins to form seeds, which are subsequently scattered over long distances.

Reference. During the dormant period, the orchid should be watered about once every two weeks. At this time, you also need to make sure that excess liquid flows out of the pot well and does not stagnate.

If the orchid has not bloomed, you should still give it a dormant period. At this time, you need to reduce watering, organizing the next one only after the root system is completely dry.

What mistakes can you make and how to fix them?

Excessive irrigation

Excessive and frequent watering is detrimental to the orchid. When there is stagnation of water in the soil, it becomes denser, foci of rot appear in it. Rotting reaches the root system. If measures of assistance are not taken in time, the process of growth and nutrition of the flower is disrupted, and it soon dies.

How to save a plant:

  1. First of all, you need to remove the flower from the pot, dry it well.
  2. Trim off any rotten roots.
  3. After processing the cuts with activated carbon powder, you can transplant the orchid into a new pot (you can read about watering orchids after transplanting here).

If you don't have a lot of experience with orchid farming, it is best to always place the drainage in pots to avoid overflow and root rot. The best material for drainage is regular foam. If other materials are used, there is a risk of insect infestation. In addition, you should only select pots that have multiple drainage holes.

Insufficient hydration

A dry period is much less detrimental to an orchid. This flower easily tolerates an anhydrous period for a long time, since the roots and leaves accumulate enough moisture. But if you water the plant a little for a long time, the root system dries up, its nutrition is disrupted, the orchid stops growing and no longer blooms.

Attention! If it is not enough to water the orchid during the flowering period, the flowers will dry out early and the buds will stop blooming.


  1. How often you water your orchid depends on many factors.
  2. It is impossible to define a clear timetable once and for all.
  3. Before watering the plant, you need to be sure that the soil and roots are dry enough.
  4. During the flowering period, you need to water more often, during the dormant period - less often.
  5. For such a delicate plant as an orchid, both overflow and insufficient watering are destructive. Neither one nor the other should be allowed, otherwise the flower may die.
