Orchids are perennial flowering plants with evergreen foliage. Varied and colorful, these tropical flowers are easy to grow indoors but need 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.

After brewing a good cup of coffee, don’t throw away the coffee grounds, as they are very beneficial for plants. You can use it to prepare a liquid fertilizer that you will use to water your orchids and fertilize them.

Why water orchids with a coffee grounds solution?

Fertilizing plants is important. This feeds them and provides them with the essential elements for their proper growth. Plants should only be fertilized during their growing period. In winter, it is advisable to stop all fertilization, and for good reason, plants go into dormancy and fertilizing them during this period could promote weak, etiolated growth, and make plants susceptible to disease and parasite attacks.

If you grow beautiful orchids indoors, consider fertilizing them with coffee grounds. The latter is a fertilizer that is 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 disease. However, care should be taken not to use over-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 that this flowering plant needs. In fact, phosphorus promotes the photosynthesis of orchids, nitrogen stimulates cell renewal and allows for abundant flowering. As for potassium, it favors the good growth of this plant.

How to prepare an orchid fertilizer 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, as this is their vegetative rest period.

In addition to watering your flowering plant with this liquid fertilizer, you can create rich potting soil for your orchids by mixing 1/4 coffee grounds with 3/4 garden soil.

What are some mistakes to avoid when using ground coffee 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 aphid or mealybug attack. This could make the infestation worse.

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 moist, it can promote mold growth. Keep in mind that coffee grounds can be saved for later use 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 it needs for growth.
