Coffee grounds, a booster for your orchids
Coffee grounds, a residue often discarded after your espresso or filter coffee, contains essential nutrients such as phosphorus, potassium and nitrogen, which promote healthy and vigorous growth.
How to use it
- Directly in the substrate: Mix a small amount of coffee grounds with the aerated soil of the orchid, but without excess so as not to overstate the soil.
- Compost: Pair coffee grounds with other organic waste to enrich a balanced compost, which you can then incorporate into the substrate.
In addition to its nutritional properties, coffee grounds also acts as a natural repellent against certain parasites, such as midges or snails.
What to avoid to preserve your orchids
Even with the best of intentions, some mistakes can weaken your orchids. The main ones to avoid are:
- Too much watering: The roots of orchids, sensitive to excess water, may rope if they remain constantly in moisture.
- Overdose of lemon or coffee grounds: An excess could upset the balance of the substrate and weaken the plant.
- Unsuitable substrate: Orchids do not thrive in a conventional soil; prefer a well-drained and light mixture, consisting mainly of bark.
