Watering Orchids – Practice Makes Perfect
When considering watering orchids, many immediately think of the tropical qualities of the plant. Does that mean that since they are tropical, they like lots of water and humidity? Yes and no. In nature, tropical plants live in trees, and are naturally exposed to drenching rains that may last hours or days. Some orchid species adapt to little rain or weeks without.
These incredible plants have adjusted to these habits of nature, and with a little study of your orchid, you will know how to achieve just the right amount of water for your plant’s needs. Common watering mistakes include watering too often and watering at night. Pay attention to your orchid’s watering cues, and know what you’re growing.
When watering orchids, remember that clay, plastic, or decorator types of pots will often determine watering frequency. Clay pots, being more absorbent, will require more watering. All pots should have good holes and slots, and a system of excellent drainage for the orchid. Orchid roots sitting in water will eventually die.
Large pots that tend to hold water in the middle are also bad, as they cannot efficiently drain and dry out for the optimum health of the plant. Broken terracotta in the pot bottom is good, or an inch or two of pebbles. This will help achieve good drainage.
In nature, since these plants are used to being drenched by rainwater, this is always a good choice for watering, if you can collect it. Reverse osmosis water is good, as is distilled water. Never use water that is too salty, like softened water, and some well water. The most frequent over watering sign in orchids is yellow leaves.
If you see this when watering orchids, don’t water for a few weeks. The potting material, species of orchid, temperature of the area, and humidity are all factors that affect watering. Fresh air from windows or central air heating or cooling will dry out your plants more quickly.
In watering orchids, you will gain experience. You will acquire patience and instinct as you work with your individual orchid. Even if the surface of the plant is dry, never allow the bottom of it to sit in water. A good method is to water from the top, until excess runs through the drain holes.
You can dunk your orchid pot in water and let it soak for about 15 minutes. Don’t immerse above the top ½ of the pot rim. Vanda orchids can be left floating for awhile. Look for tiny droplets on the root system when removed.
Epiphytes are orchids that in nature grow clinging on trees or stones. Their roots are actually distinctive structures that are entirely different than usual plant roots. These roots are enclosed by a super thin, transparent tissue called velamen.
This specialized tissue rapidly soaks up water, adheres to coarse surfaces, and aids in the transfer of nutrients and alkali. It actually works like a water meter to the plant. It is a precise gauge to use when watering your orchids. Arid velamen is filmy and pale, and newly watered velamen is supple and variegated.
