If you’re looking at how to water orchids in bark, it can be a bit different than watering other plants. Depending on the species, the amount of water needed differs, but the telltale signs of when they need water is the same. Once you know what to look for, it’s easy, and you’ll be left with amazing blooms that will be the envy of the neighborhood.
Orchids That Need More Water Than Most
Knowing how much water your orchid species require is important. For example, these species need more water than others. Here are some general guidelines for orchids that need more water than most:
- Paphiopedilums (slipper orchids) prefer moist but not soggy soil and should be watered when the top layer of bark feels dry to the touch.
- Phalaenopsis (moth orchids) also like to stay relatively moist but should not be overwatered as they are susceptible to root rot.
- Dendrobiums that grow in humid, tropical environments should be watered when the top layer of bark feels dry to the touch.
- Vandas are epiphytic orchids and grow naturally in the tropics. They require more frequent watering than most. They should be watered several times a week and allowed to dry out between waterings.
Orchids That Need Little Water
Orchids that need frequent watering are the exceptions rather than the rule. Most have adapted to environments with infrequent rainfall, so they generally prefer to dry out between waterings. The orchids require very little water:
- Cattleyas or Cattleya orchids are epiphytes that grow naturally on trees in tropical environments. They prefer to dry out between waterings and should only be watered when the top layer of bark feels dry to the touch.
- Oncidium orchids come in many different varieties, but most prefer to dry out between waterings. Water them when the bark feels dry to the touch, but be careful not to overwater as they are susceptible to root rot.
- Miltonia orchids are often called “pansy orchids” because of their large, showy flowers. They prefer to dry out between waterings and should be watered when the top layer of bark feels dry.
- Dendrobium nobile prefers cooler temperatures and drier conditions and needs to dry out between waterings.
Individual plants have different water requirements. A simple rule of thumb is to carefully monitor your plant’s health and add or subtract water when needed.
When to Water
If you’ve got an orchid that is prone to root rot, such as the Oncidium orchid, you don’t want to overwater. To tell if it’s time to water, there are several easy telltale signs.
First, simply pick up the plant. If the plant feels heavy, there is still water the bark has soaked up – so there is no need to add any more.
The orchid’s leaves are another easy way to tell. Are they drooping and limp? Do they look dehydrated, wrinkled, or shriveled? If they are, it’s time to water. And, of course, you can feel the bark. If it is dry, it’s time to water.
The last way to tell if you need to water is the plant’s roots. If they are still plump and green, you’re all good. If they look dry and shriveled, it’s time to water them.
These simple and easy steps will ensure you’re giving your orchid enough water but not too much.
How to Water
Once you’ve established it’s time to water, make sure to water it thoroughly. Give it enough water so that it runs out of the bottom of the pot.
Then, let the roots and bark dry out completely, which can take anywhere from a few days to a couple of weeks, depending on the humidity and temperature.
How to tell if you’ve overwatered
It is just as important to water as it is not to over water. If you’re afraid you’ve gone overboard, here are some signs you need to cool it on the water.
- yellow leaves
- mushy roots
- foul smell coming from the pot
If you notice any of the above, you may want to adjust your watering schedule. As the seasons change, your orchid’s watering needs may change as well. In general, orchids need less water during the winter months when the air is drier, and the temperatures are cooler.
Are you constantly adding water, and the bark is still dry and the leaves dehydrated, you might need a humidifier or to place a tray of water to help keep the air moist. Your plants will thank you for it.

Orchid Blooms
Getting blooms on orchids can be as tricky as watering – each species has its own requirements, but here are some ways that will take care of most.
Light
Most orchids prefer bright, indirect light and should receive it 12-14 hours per day.
Temperature
For the most part, orchids prefer a temperature range of 60-80°F during the day and 50-70°F at night. However, some orchids require cooler temperatures to bloom.
Fertilization
Feed your orchids every two weeks, giving them a balanced mix, or you can use a slow-release tablet specially formulated for orchids that can last up to 180 days.

Conclusion
Growing orchids doesn’t have to be difficult – knowing each flower has different requirements for both water and food is necessary. Just look for the signs your plant gives off, Is it limp? Does it have yellow leaves? Is the bark dry or moist?
