Orchids belong to the Orchideaceae family and are one of the largest plant families in the world. These fascinating flowers originate from almost every part of the world, with the exception of Antarctica.
Origin of Orchids
Originally native to tropical and subtropical climates, they can be found in an amazing variety of habitat types, from forests to meadows. Orchids are known to bloom in many different shapes and colors, making them a popular element in gardens and interior design.
Their ability to adapt to different habitats is remarkable and has led to the creation of thousands of species, including the well-known Phalaenopsis, Cattleya and Dendrobium.
Biodiversity
The diversity of orchids is impressive: it is estimated that there are over 25.000 different species that vary greatly in shape, color and size. Some common species are Phalaenopsis, known for their large blooms and easy care, and Cattleya, whose striking flowers are often used in floriculture. Miniature orchids, such as Masdevallia, are also very popular. In addition to these, there are many other species that have special requirements for light, water and temperature. This makes it important to find out about the respective species in order to create optimal growing conditions.

Care instructions for orchids
Proper care is crucial for orchids to thrive and bloom at home. Here are some common mistakes when caring for orchids and tips for avoiding these mishaps:
1. Overwatering
Overwatering is one of the most common mistakes when caring for orchids. Too much water can cause root rot, which leads to the formation of brown or mushy roots. Orchids need well-draining soil, and it is important that the pot has holes for water drainage. A good tip is to let the soil dry out slightly before watering, so that it is always slightly moist but never soggy. Also, use a clear pot to observe the roots and make sure they are healthy.
2. False light
Orchids need a lot of light, but direct sunlight can be harmful. A window with indirect sunlight is ideal. Too little light can cause the plant to remain weak and reluctant to bloom. Watch the leaves: if they are dark green, this could be a sign of a lack of light. It is better to place the orchids in a location with bright, filtered light, such as an east or west-facing window.
3. Temperature fluctuations
Orchids are sensitive to sudden changes in temperature. They prefer temperatures between 18°C and 24°C and should be protected from cold drafts or direct heat sources. Temperatures below 15°C can seriously affect growth, while excessive heat can prevent flowering. Make sure that the room temperature remains constant and that the orchid is not near air conditioning or radiators.
4. Insufficient humidity
Orchids often come from humid environments and require high humidity. Values between 40% and 60% are ideal. Air that is too dry can lead to brown leaf tips. Use a humidifier or place the orchid on a bed of pebbles filled with water to increase the humidity. Also spray water on the leaves regularly to maintain moisture without getting the flowers wet.
5. Wrong fertilizer
Choosing the right fertilizer is crucial for the growth of orchids. Many hobby gardeners use the wrong fertilizer or fertilize too frequently. A special orchid fertilizer is necessary because it is tailored to the needs of the plants. Fertilize every 2-4 weeks during the growing season, but only at half the recommended concentration. Over-fertilizing can cause root damage, so make sure you always follow the instructions on the packaging.
6. Repotting at the wrong time
Orchids should generally be repotted every one to two years, but not during flowering. Repotting too early can stress the plant and affect flowering. The best time is after flowering, when the roots are visible. Use fresh orchid soil to improve the supply of nutrients. Make sure the roots are well aerated to avoid rot.
7. Neglect of the flower stems
Many people don't know what to do with the flower stems after the orchid has finished flowering. Instead of cutting them off immediately, observe whether the flower stem remains green or turns brown. A green stem can continue to bloom, while a brown stem should be trimmed. Cut the stem about an inch above the last node. This will help encourage new growth and keep the plant healthy.
8. Wrong Pot
Choosing the right pot can also be crucial to an orchid's well-being. A pot with too many holes can cause the soil to dry out quickly, while one with too few holes will drown the roots. Use a pot specifically designed for orchids that provides the necessary ventilation. A clear pot can also help monitor root growth.
9. Inadequate care during flowering
During the flowering period, orchids require special attention. Too little light or incorrect watering can inhibit flower formation. Make sure the plant is in a bright, warm area and that the soil is kept evenly moist. Also make sure to protect the flowers from drafts and temperature fluctuations.
10. Explanation of the flowering period
Many owners are unsure how long an orchid should bloom and what to look out for. It is quite normal for some species to bloom for several months, while others only need a few weeks. It is important to be patient and continue to care for the plant well, even if the flowers fall off. New flowers can sprout at any time if the conditions are right and the plant is healthy.
11. Failure to comply with a regularity
Orchids require regular care, but many people forget this and only care for their plants sporadically. Develop a care plan to check on the orchid regularly and make sure all its needs are met. This includes watering, fertilizing, and monitoring for pests. In turn, consistent care will help keep the orchid healthy and its flowers in full bloom.
12. Hidden pests
Pests such as scale insects or spider mites can sneak in unnoticed and damage the orchids. Check the leaves and roots regularly for signs of pests. Regularly cleaning the leaves can help prevent pests. If pests are visible, treat them immediately with a mild soap solution or special plant protection products. A preventative approach is the best way to prevent diseases and pests.
13. Wrong flower color
Many people are surprised to see the color of the flowers change after care. This often happens due to stress or inadequate care. Be careful about the type of orchid you choose, as certain varieties can change color due to lighting conditions and nutrient supply. Follow the care instructions and give the plant the best conditions to develop its natural color splendor.
14. Lack of information
Often there is a lack of basic information that is crucial for the successful growth of orchids. Research the specific needs of your orchid species to ensure it can thrive in the best possible conditions. There are many resources, books and online communities that offer valuable tips on orchid care. Talking to experienced orchid lovers can also help to deepen your understanding of these beautiful plants.
15. Generalization of care
Not all orchid species have the same care requirements. Generalizing can lead to misinterpretation and put the health of the plants at risk. Learn about the specific needs of each species to find the best care approach. Consider factors such as light, humidity and temperature to ensure customized care. This will not only improve growth but also ensure impressive blooms.
