Nitrogen: Found in large quantities in coffee grounds, it promotes robust vegetative growth.
Magnesium & Calcium: Essential for the health of orchids, they help in the formation of roots and cells.
Potassium: Promotes flower and fruit production.
Acid Loving Plants
Orchids generally prefer slightly acidic to neutral pH levels (6.0 – 7.5). Since coffee is naturally acidic, it is a potential complement for orchids.
Coffee has antimicrobial properties that may reduce the risk of root rot and repel certain pests.
The Benefits of Coffee for Orchids
Improved Flowering
By providing essential nutrients, including potassium, coffee can encourage orchids to bloom.
Improvement of Soil Structure
Coffee grounds can improve the aeration and drainage of the orchid mix. These plants being epiphytic, they require a well-draining substrate.
Practical Durable
Using coffee for orchids is a sustainable practice, transforming a waste product into a beneficial supplement.
