Orchids are perennial flowering plants with evergreen foliage. Varied and colorful, these tropical flowers are easy to grow indoors but do require maintenance. To do this, you can use natural fertilizers to fertilize them and promote their flowering. That said, discover the value of watering orchids with a coffee grounds-based solution.
Why water orchids with a coffee grounds solution ?

Plant fertilization is important. This feeds them and provides them with the essential elements for proper growth. Plants should only be fertilized during their growth period. In winter, it is advisable to stop all fertilization, and for good reason, the plants go into dormancy and fertilizing them during this period could promote weakened and weakened growth, and make the plants susceptible to diseases and parasite attacks.
If you grow beautiful orchids indoors, consider fertilizing them with coffee grounds. The latter is a fertilizer highly appreciated by indoor plants. In fact, it provides them with nitrogen and phosphorus, which plants assimilate in the long term, as well as potassium and magnesium, which plants assimilate quickly. These inputs boost plant growth and make them more resistant to diseases. However, care must be taken not to use excessively ground coffee, so as not to damage the flowering of the plants.

That said, coffee grounds are very beneficial for orchids because they contain the nutrients this flowering plant needs. In fact, phosphorus promotes photosynthesis in orchids, nitrogen stimulates cell renewal and allows abundant flowering. As for potassium, it favors the good growth of this plant.
How to prepare a fertilizer for orchids based on coffee grounds?
To fertilize your orchids, you can prepare a liquid fertilizer from coffee grounds. To do this, simply mix this coffee residue that you collect from your coffee maker, in a container, with two liters of water. Stir and let the mixture sit for 24 to 48 hours in a cool place. Then strain the solution and use it to water the orchids.
Keep in mind that it is advisable to fertilize these plants every 21 days, in spring, when the buds appear. In summer, orchids need fertilizer every 7 days. However, it is important not to fertilize orchids in winter, since it is their vegetative rest period.
In addition to watering your flowering plant with this liquid fertilizer, you can create a rich potting soil for your orchids by mixing ¼ coffee grounds with ¾ garden soil.
What are some mistakes to avoid when using coffee grounds to fertilize orchids?
Before using ground coffee for your orchids, keep in mind that it is not advisable to put it at the foot of plants that have suffered an attack by aphids or mealybugs. This could worsen the infestation.
It is also not recommended to use coffee grounds to fertilize young orchids. This could slow their growth. If you choose to spread the coffee grounds around the orchids, remember to dry them first, before adding them to the substrate. If you use it wet, it may promote mold growth. Keep in mind that coffee grounds can be saved to use later to fertilize your orchids. Just try to keep it in a cool place.
You don’t need to have a green thumb to improve your orchid. With this trick, provide your plant with all the nutrients necessary for its growth.
