Unlock the beauty of Orchid in Water cultivation with our comprehensive guide. Master the secrets to successful care for stunning water-cultured orchids.
In the traditional approach, orchids are typically grown in organic substrates or planting media to produce beautiful orchid stems. However, with the entirely new method of growing orchids in water, you will have a stunning orchid plant from roots to blossoms.
What is Water Culture Orchid Growing?
Water culture orchid growing is a method of cultivating orchid plants without using soil or traditional planting media. Instead, it relies on solutions, water, and planting media to support the plant’s growth. Proper technique and care are essential for the successful development of orchids using this method.
While not a novel approach, many people adopt this method to economically cultivate various plant varieties with high yields.
Benefits of Growing Plants in Water
Compared to other traditional orchid growing methods, water culture offers several benefits:
- Reduced land usage helps minimize the risk of harmful soil-borne pathogens.
- This method can be applied in various small spaces.
- Easy automation reduces the need for extensive care and attention.
- Plants efficiently absorb essential nutrients from the planting media, conserving water and soil.
- Water-based cultivation is a clean method that reduces exposure to pathogens.
- Simple care, adjustment, and nutrient modification throughout the plant’s growth journey.
Guide to Growing Orchids in Water
In addition to the requirements for the orchid variety, you must meet the necessary conditions as outlined below.
Preparing Tools and Equipment
First, we need to prepare the necessary tools, orchid varieties, and some essential nutrients.
- Orchid Garden Design: If you plan to cultivate orchids for commercial purposes, it’s advisable to design a sturdy and durable orchid frame. Consider using black or gray mesh for shading. In the case of rooftop or patio orchid growing, place them alongside other decorative plants to reduce the heat and dryness from the surrounding metal or concrete structures.
- Planting Medium: You can use various planting media for orchids, such as charcoal, coconut fiber, or peanut shells.
- Plastic Mesh Pot: Select trays that are suitable in size for the orchids you intend to grow.
- Hydroponic Solution: Choose a suitable nutrient solution for your orchids. Follow the mixing ratios as indicated on the package instructions. Use a pH pen and a PPM (parts per million) meter to ensure accurate nutrient concentration for your plants.
- Orchid Varieties: If you intend to grow orchids for commercial purposes, consider selecting varieties like Dendrobium, MoNaKa, Oncidium, Phalaenopsis, Vanda, as they are known for their beauty and continuous flowering. For recreational growing, Dendrobium and Phalaenopsis are highly suitable choices, as they are easy to care for.
Hydroponic Orchid Growing Guide
Place a layer of charcoal or foam at the bottom of the container to ensure proper air circulation for the plants.
Add a layer of crushed and thoroughly washed charcoal to the pot, filling it up to about half the pot’s height.
Insert the Orchid plant and spread an additional layer of coconut husk, cut into large pieces, to retain moisture. Note: The coconut husk should be soaked for approximately 24 hours and thoroughly rinsed to remove any toxins.
Place the Orchid onto the hydroponic system so that it can receive care through the hydroponic solution, providing nutrients for its growth.
Care Techniques
After correctly applying the fundamental planting techniques, when caring for water-cultured orchids, factors such as light, humidity, watering, and nutrients are crucial.
Light: Orchids cannot tolerate strong sunlight, so it’s advisable to use shading nets to reduce light exposure. The optimal light level is around 65-70%.
Watering: After planting the Orchid, water it immediately and maintain watering twice a day. Avoid overwatering; each time, provide just enough moisture. The best times for watering are early in the morning or in the cool evening.
Hydroponic Nutrient Solution: The nutrient concentration and dosage for Orchids depend on their developmental stage.
Pest and Disease Control
It is essential to watch for signs of rot on your orchids, as this disease can develop rapidly and potentially kill the plant within a few days. If you observe dark spots on the leaves, immediate spraying with appropriate pesticides is necessary. If both leaves and roots are affected, you may need to use sterilized scissors or a knife to cut away the affected areas. In severe cases, entire leaves or roots may need to be removed.
Ensure that the cut areas are disinfected using Vadơhn mixed with Zineb. Afterward, isolate the diseased plant, as these diseases can spread quickly. Once your orchid has a flower spike, avoid changing its position, as this can lead to flower bud drop. Insufficient humidity and excessive fertilizer use can also cause yellowing and curling of flower buds. After the flowers have withered, you can cut the flower spike down to the fourth eye (leaving four eyes). These eyes often produce lateral shoots that may bloom during the sunny season.
Tiny mites are often hard to distinguish with the naked eye. With a strong magnifying glass, you can spot tiny, slightly reddish insects. Additionally, larger pests like scale insects and mealybugs can cause significant damage. Using Serpa at a concentration of half a teaspoon per 4 liters of water will yield effective results. Afterward, daily watering with diluted tea for your orchids can stimulate growth and also help eliminate potential bacterial infections due to the tannins in the tea.
