Fertilizer for orchids
Last reviewed: 19.01.2025
Proper fertilization is crucial for the health, growth, and abundant blooming of orchids. Orchids differ from most houseplants in their nutrient requirements, and selecting the right fertilizer requires careful consideration. In this guide, we will explore which fertilizers are best for orchids, how to use them, and how to prepare homemade feeding solutions.
Fertilizer for orchids for blooming
Orchids need balanced nutrients to stimulate growth and blooming. The best fertilizer for orchid blooming contains three essential elements: nitrogen (n), phosphorus (p), and potassium (k) in equal proportions, such as 20-20-20, or with a slightly higher phosphorus content to support flowering, such as 10-30-20. A high phosphorus level promotes bud formation and helps the orchid maintain prolonged blooming.
- When to fertilize orchids: it is recommended to fertilize orchids during the active growing period, which usually occurs in spring and summer. During blooming, reduce the amount of fertilizer slightly to avoid overloading the plant.
- How often to fertilize: fertilize orchids every two weeks during the active growing period and once a month during the dormant period. This helps maintain steady growth without an excess of nutrients.
Which fertilizers to use for orchids?
- Liquid fertilizers: liquid fertilizers are the most convenient option for orchids. They are easy to dilute in water and distribute evenly throughout the substrate. Popular brands include "bona forte," "fertika," and "miracle-gro."
- Homemade fertilizers: homemade fertilizers can also be used for orchids. For example, a solution of succinic acid stimulates root growth and strengthens the plant's immunity. Banana peels and garlic infusions also help enrich the substrate with micronutrients beneficial for orchids.
- Organic and mineral fertilizers: organic fertilizers, such as compost tea, are rich in beneficial micronutrients and support the overall health of orchids. Mineral fertilizers can be useful for stimulating growth, but it is important to follow dosage guidelines to avoid damaging the roots.
Watering orchids with fertilizers: how to do it properly
- Diluting fertilizer: orchid fertilizer should be diluted in water according to the manufacturer's recommendations. Usually, a small concentration is needed, such as 1/4 of the usual dose, as orchids are sensitive to excess salts.
- Watering method: watering orchids with fertilizer is done using the immersion method. Place the orchid pot in a container with the fertilizer solution for 10-15 minutes so that the roots can absorb the nutrients. Afterward, place the pot on a rack to allow excess liquid to drain.
- Alternating with regular watering: it is important to alternate fertilizing with regular watering using plain water. This helps prevent salt buildup in the substrate, which can harm the roots.
Best fertilizer for orchids: overview of popular products
- Bona forte for orchids: a balanced fertilizer containing essential micro- and macronutrients that support blooming and the overall health of the plant. It can be used both during active growth and flowering.
- Fertika for orchids: this fertilizer is suitable for regular use and provides the roots with all necessary nutrients. Fertika helps maintain steady growth and strengthens the plant's immunity.
- Japanese fertilizers for orchids: these fertilizers often come in the form of ampoules or sticks that are convenient to use. They provide a slow release of nutrients and are a great option for those who do not want to fertilize frequently.
Homemade fertilizers for orchids
- Succinic acid: succinic acid stimulates root formation and accelerates orchid growth. Dissolve one tablet of succinic acid in one liter of water and use it to spray the roots and substrate.
- Banana peel: a banana peel infusion is rich in potassium and magnesium. Chop the peel and soak it in water for 24 hours, then strain and use for watering.
- Garlic water: garlic helps strengthen the plant's immunity. Crush 2-3 cloves of garlic, pour one liter of water, and let it steep for 24 hours. This infusion can be used to spray the leaves and substrate.
How to apply fertilizers for orchids: tips and recommendations
- Avoid overfeeding: overfeeding orchids can lead to root burn and a decline in plant health. Always use fertilizers at a lower concentration than indicated on the package.
- Fertilizing during blooming: during blooming, it is better to use fertilizers with a higher phosphorus and potassium content to support the buds and prolong the flowering period.
- Applying fertilizers after repotting: after repotting, orchids are usually stressed, so fertilizers should be applied no earlier than 3-4 weeks after repotting. This gives the roots time to adapt to the new substrate.
Liquid and compound fertilizers for orchids
- Liquid fertilizers: liquid fertilizers are easy to use and allow nutrients to be distributed evenly throughout the substrate. They are quickly absorbed by the roots, making them an ideal choice for feeding orchids.
- Compound fertilizers: compound fertilizers contain a complete set of micro- and macronutrients necessary for orchid growth and flowering. They can be used in both liquid and granular forms, depending on the plant's needs.
Conclusion
Fertilizing orchids at home is an important part of caring for these beautiful plants. Using the right fertilizers, such as "bona forte," "fertika," or japanese ampoules, helps orchids grow healthy and bloom profusely. It is important to alternate fertilizing with regular watering and avoid overfeeding. With the right approach to fertilization, your orchids will delight you with their beauty for many years.
