Orchids have always been one of the most sought-after ornamental plants, but in the past, people believed orchids were difficult to grow and required meticulous care. However, recently scientists discovered a breakthrough for orchids—they can be watered with ferrous sulfate. This new discovery has aroused great interest among people. Let's explore this together.
1. The Role of Ferrous Sulfate
Ferrous sulfate, also known as divalent iron, is an important plant nutrient element. It can increase the iron content in the soil, helping to improve the drought resistance, disease resistance, and nutrient absorption capacity of orchids.
2. Why Can Orchids Be Watered with Ferrous Sulfate?
Traditionally, orchids are considered plants that prefer acidic soil, and ferrous sulfate itself is acidic. Many people believe that ferrous sulfate would harm orchids. But scientific experiments have found that orchids can tolerate certain concentrations of ferrous sulfate and even obtain nutrients from it.
3. How to Water with Ferrous Sulfate?
Orchids can absorb ferrous sulfate through their roots. Generally, about 1 kilogram of ferrous sulfate needs to be added per 30 square meters of land, but the specific amount should be determined based on soil properties and plant needs. When watering, you can directly add ferrous sulfate to the water and let it evenly permeate into the soil.
4. Precautions
Although orchids can be watered with ferrous sulfate, excessive amounts will harm them. You need to control the dosage when adding ferrous sulfate. At the same time, ferrous sulfate makes the soil more acidic, which also requires timely adjustment of the soil pH value.
5. Ferrous Sulfate and Orchid Growth Environment
Orchids usually grow in warm, humid, and well-lit environments. While ferrous sulfate can increase the iron content in the soil, enhance the drought resistance and disease resistance of orchids, making them better adapted to natural environments.
6. Effects of Ferrous Sulfate on Orchids
Ferrous sulfate not only promotes the growth and development of orchids but also improves their flowering period and color, making them more beautiful. At the same time, ferrous sulfate can also enhance the disease resistance of orchids and reduce the occurrence of diseases.
7. Orchid Planting Techniques
In addition to adding ferrous sulfate when watering, there are several other points to note when planting orchids: Choose fertile, breathable, and well-draining soil; Control the amount and frequency of watering to avoid overly wet or dry soil; Maintain adequate light and avoid prolonged exposure to direct sunlight.
8. How to Identify Symptoms of Ferrous Sulfate Deficiency?
A deficiency of ferrous sulfate can cause symptoms such as yellowing leaves, green veins, and yellow spots on leaf edges in orchids. At this point, you can appropriately add ferrous sulfate to help the orchid resume normal growth and development.
Through this article, we have learned that orchids can be watered with ferrous sulfate and understood the important role of ferrous sulfate in the growth and development of orchids. By reasonably adding ferrous sulfate, we can help orchids better adapt to natural environments, thrive, and thus become even more beloved ornamental plants by people.
