Using Diluted Black Coffee
Preparation: Prepare a diluted coffee solution using one part brewed black coffee to three parts water. Make sure the coffee is cooled.
Application: Substitute this solution for water during regular watering
Frequency: Use the coffee solution once a month.
Using Coffee Grounds
Drying: Spread the coffee grounds on a flat surface and allow them to dry completely.
Mixing with the Substrate: Integrate the dried coffee grounds into the orchid mixture at a ratio of 1:5.
Monitoring pH Levels
Test the pH periodically to ensure it stays within the ideal range.
Precautions and Best Practices
Avoid Excess
Orchids are sensitive. Too much coffee can damage them.
Filtered Coffee is the Best
Unfiltered coffee can be harmful in large quantities. Always use filtered coffee.
Watch for Pests
Although coffee has repellent properties, it can attract certain pests.
Not a Complete Substitute
Coffee is a supplement, not a complete fertilizer. Continue to use your usual orchid fertilizer.
Using coffee in orchid care is an exciting and sustainable approach. By understanding the science and applying it carefully, orchid lovers can experiment with coffee in their care regimen. However, monitoring and moderation are essential.
