Ingredients
While we’re aiming for fertilizer-free blooming, your orchids still need the right environment. Think of these as the “ingredients” for success:
Proper Potting Medium: A well-draining mix is crucial. Bark, sphagnum moss, charcoal, and perlite are common components.
Good Air Circulation: Essential to prevent fungal diseases and root rot.
Adequate Light: Bright, indirect light is generally best. Avoid direct scorching sun.
Appropriate Watering Can: A long-spouted can helps direct water to the roots without splashing the leaves or crown.
Misting Bottle (optional): For increasing humidity.
Tips
1. The “Soak and Dry” Watering Method
Nursery owners swear by this technique for summer watering. Overwatering is the quickest way to kill an orchid.
How to do it: Instead of frequent small sips, give your orchid a thorough drenching. Place your potted orchid in a sink or basin and run lukewarm water through the potting medium for several minutes until it’s completely saturated. Alternatively, you can submerge the pot (up to the rim) in a bucket of water for 10-15 minutes.
Why it works: This ensures all roots are hydrated and flushes out any accumulated salts. Crucially, allow the potting medium to dry out almost completely before watering again. Stick your finger into the medium – if it feels damp, wait. If it feels dry, it’s time to water. This mimics their natural habitat where they experience periods of rain followed by dry spells.
2. The Power of Increased Airflow
Summer often brings higher temperatures and humidity, which can be a recipe for disaster for orchids if airflow is poor.
How to do it: Ensure your orchids are not crammed together. Space them out to allow air to circulate freely around their leaves and pots. If growing indoors, consider using a small fan on a low setting, not pointed directly at the plants but circulating air in the room. Open windows for natural ventilation.
Why it works: Good airflow prevents the buildup of stagnant, humid air around the leaves and roots, which can lead to fungal infections and rot. It also helps the potting medium dry out more evenly, supporting the “soak and dry” method.
3. Simulating a Natural Temperature Drop
For many orchid species, particularly Phalaenopsis (moth orchids), a slight drop in nighttime temperature is a key trigger for flowering.
