Watering orchids, but correctly: How often, how much and what water? The most important questions answered!

The orchids are very popular for their beautiful flowers. The right amount of watering is crucial for growth and flowering. We explain how to do this and what to look for when watering, dipping and spraying.

How often to water the orchids?

How often to water orchids and what water

For now, orchids are tropical flowers. But this does not necessarily mean that they need more and more frequent water than the other houseplants. It’s not just about the amount of water, but more importantly, how to water properly.

In their native countries, many species of orchids grow on trees. They are accustomed to tropical rain, but can easily withstand prolonged periods without water.

It is very difficult to replicate the climate conditions in the tropics (drafts, humidity and light conditions) in your own home.

So how often you water your orchid depends mainly on the period (growing season in summer or flowering season in winter).

How often to water the orchids when they bloom and when they grow.

Watering orchids in summer how often and how much

In the months between February and May, when the orchids are forming buds and during the flowering period, you need more water – it is best to water then twice a week.

In early summer (from June), when the growth phase begins, the exotic also needs regular watering – about three times a week.

In autumn and winter, the dormant phase begins. Then you can water the flower less often. It is completely sufficient if you water it every two weeks in the months between September and February. The flower can hardly use more water during this period and waterlogging can form. Or the flower continues to grow and then has little strength to form flowers during the flowering period.

The best time to water the orchids is early in the morning so that the roots, leaves and possibly the flowers can dry during the day.

During the winter months, when the humidity in the house is too low, you can pour lime-free water into a spray bottle and spray the leaves and aerial roots every other day.

Common mistakes to avoid:

  • Watering the orchids too often. Never leave the orchid standing in water. It is much better to let the substrate dry completely.
  • Watering the orchids at night: no matter what type and variety of orchid you have, the right time is always early in the morning. Always. This allows the excess water to evaporate during the day and the roots are less susceptible to fungus and disease.
  • Ignoring the indoor plant’s cues: During the summer growing season, the leaves should be green, thick and pointing upward.

How to water orchids correctly?

There are basically five different variants of how to water your orchid.

  • You can water the orchid with a watering can like any other houseplant.
  • You can also submerge the orchid in a water bath.
  • You can put water in a spray bottle and spray it on the orchid.

Watering orchids or dipping them: Which is better?

Depending on what stage the flower is in, it needs between two and eight waterings a month. But how should you water the exotic: water from below or immerse it in water after all? The immersion bath has proven to be the better alternative. This allows the roots to soak up the water better and faster. This is important, because the orchid must be able to store enough water for a short time for the “dry period” afterwards.

Before each dip, check whether the pot is heavy or light. A light pot means that the water in the substrate has already evaporated and the orchid needs to be watered again. A heavy pot means that it still has water reserves.

How to properly immerse the orchid: instructions.

Watering orchid correctly how often and when a day


1. First, fill a clean container with lukewarm water. Depending on the season, you can add some liquid fertilizer for orchids to the water.

2. Hold the pot at an angle and slowly submerge it in the water. You can additionally water the orchid from the bottom.

3. leave the orchid in the immersion bath until the roots turn grass green. This is an indication that they have stored enough water.

4. The rule of thumb is: if the humidity is high (i.e. 60° or more) and the temperature is between 10° and 20° Celsius, leave the flower in the immersion bath for 10 to 15 minutes. For low humidity and temperatures above 20° Celsius, leave the flower immersed for 30 minutes or longer.

4. Place the pot in the sink to allow excess water to drain.

Watering orchids with shot glass: right or wrong?

The shot glass method has gained popularity in recent years. It involves filling a shot glass with water and pouring it to the edge of the pot. However, this amount of water is too little for an orchid. It is best to leave the plant in the immersion bath for 15 minutes so that it can soak. If you do not have time for this, you should simply water the flower abundantly from above, just like normal houseplants.

What water is suitable?

Orchids do not like water containing lime. Rainwater is best suited. However, especially in summer it is not easy to find rainwater. In this case, you can use lukewarm, decalcified tap water or condensed water from the dryer.

Distilled water alone is not suitable for watering orchids . However, you can pour tap water and distilled water into a watering can in a 1 to 1 ratio and add some more liquid fertilizer for orchids. Stir slowly until the fertilizer is dissolved in the water and then use it to water the houseplant. You can also pour the water into a bucket and put the plant in the bucket.
