Some orchids have water-storing organs, and some do not. If you have a type of orchid that has the ability to store water, such as cattleyas or oncidiums, you should allow the orchid to completely dry out before watering. If you have a type of orchid that does not have water-storing organs, such as phalaenopsis or paphiopedilums, you should water the orchid before it is entirely dry. If you’re not sure what type of orchid you have, plan to water the orchid when it is almost dry, but still has just a bit of moisture left.
If the temperature is cool in your home, your orchid will need to be watered less frequently than when the temperature is warm. If the orchid is in a sunny window, it will need to be watered more frequently than if you place it in a shadier spot.
A pot that still contains moisture might look different, too. If your orchid is in a clay pot, it will look darker when it’s still wet. If it’s light in color, it might be time for a watering.
Look for special pots designed for growing orchids. These pots are usually made out of terracotta clay and have extra drainage holes in the sides. You should be able to find them in the same section as other planters. If you just want a quick way to water your orchid without having to transplant the orchid, you can use the ice cube method. Put the equivalent of 1/4 cup (59 ml) of frozen water (usually about three medium ice cubes) on top of the potting mix. Make sure that the ice never comes in contact with the orchid itself - it should only touch the soil. Let the ice cubes melt into the pot. Wait about a week before you do it again. This method is not optimal for the long-term health of the orchid, so only use it as a temporary solution. [2] X Research source
Do not use water that has been softened or treated with harsh chemicals. If you have a special orchid species, see if you can use distilled water or rainwater. The water should pour rapidly through the pot. If it seems to be getting stuck in the pot, the potting mix you’re using might be too dense. After watering the orchid, check the weight of the pot so you’ll be able to tell the difference when the pot gets lighter and the orchid is ready to be watered again.
If you see excess water sitting on the leaves, wipe it off with a paper towel. A few minutes after watering, check the saucer and empty it out so no water sits near the orchid.
If you don’t know if your orchid needs another mist, check to see if it feels dry. Don’t let water collect on the leaves. You can find a spray bottle in most department stores or online.
