Orchids are a favorite among flower lovers for their one-of-a-kind beauty and amazing variety. This genus of plants is truly a wonder to behold. It includes more than 25,000 different species (some sources say as many as 28,000), and each one is as unique as the next. But what really sets them apart is their incredible beauty. These flowers come in every color and shape you can imagine, and they’re truly a sight to see! Orchids are native to tropical and subtropical regions around the world, from rainforests to mountainous areas, and they can even adapt to different climates! Their adaptability and hardiness have made them popular plants for growing indoors, where they can bring an exotic touch to any space.
When and why to repot orchids
Repotting orchids is a key aspect of their care that contributes to their longevity and healthy growth. There is no set time for repotting, but most experts recommend this step be done every two to three years. The best time to repot is after flowering and before the start of the new growing season, when the plant is recovering its energy and starting to produce new shoots. This is an ideal time as the plant will recover quickly from the transplanting and adapt better to its new environment.
Other reasons for repotting orchids can be poor substrate quality, signs of root rot or if the substrate becomes too dense and does not hold enough moisture. If the substrate is decayed, full of pests or a drying salt coating, it is time to replace it. Repotting is also important if the plant is showing signs of stagnant growth, which may indicate that it is clogged with a root system or needs fresh nutrients.
Preparing for repotting
Preparation is a key step for successful repotting. Make sure you have everything you need before you start. Choose a suitable substrate – orchids need a special mix that allows good aeration and drainage. A typical orchid substrate contains bark, perlite and sometimes coir. This mixture promotes a healthy root system and prevents water build-up that could lead to root rot.
A transparent pot is ideal as it allows you to monitor the health of the roots. The new pot should be 2 to 3 cm larger than the existing one. You will also need clean scissors to trim the roots, charcoal powder or cinnamon to treat the cutting surfaces, and of course a new potting mix.
How to repot an orchid step by step
Preparing the plant: Before transplanting the orchid itself, it is a good idea to soak the plant in water to soften the roots. This will make it easier to remove them from the pot and remove the old substrate.
Removing from the pot: Carefully remove the orchid from its original pot. If the substrate crumbles easily, this will be easier. Make sure there is no damage to the roots during this process.
Inspect the roots: Once you have the orchid outside, examine the root system carefully. Healthy roots should be strong and green. Damaged or dead roots that are brown, soft or have shown signs of rot should be removed. Use clean shears and treat the cutting surfaces with charcoal powder or cinnamon to prevent infections.
Preparing a new pot: Add a layer of potting medium to the bottom of the new pot. Then place the orchid in the pot and gently add substrate around the roots. It is important that the roots are not excessively tamped down. Gently tamp the substrate to stabilise the plant.
After repotting, place the orchid in a location with plenty of indirect light. Avoid watering for the first seven days to give the roots time to adjust. After this time, start watering lightly to avoid overwatering.
Care after transplanting
Repotting orchids is not just about changing the pot. It is important to ensure that the orchid has optimal conditions for recovery and growth. Keep the plant in a place with sufficient but indirect light to avoid burning the leaves. The ideal temperature for most orchids is between 18 and 24°C during the day and slightly cooler at night. Orchids are sensitive to waterlogging, which can lead to root rot. Water the plant once a week, less in winter, and always make sure the water drains well. It is better to water less often than too often, and always make sure the substrate dries out slightly between waterings.
Regular fertilisation is also important. Use special orchid fertilisers that contain a balanced mix of nutrients. Fertilisation should take place every two weeks during the growing season, which usually includes spring and summer. In winter, when the plant slows down, you can reduce the frequency of fertilisation.
Monitoring and maintenance after transplanting
After repotting orchids, it is important to monitor the health of the plant. Keep an eye on the new flowers, which should be bright and healthy. If the plant begins to show signs of stress, such as brown or yellow leaves, this may be a sign of problems with the root system or environmental conditions. To prevent disease and pests, check the plant regularly for pests such as aphids or insects. If you find pests, use natural insecticides or a mild soap on the plants. Keeping the area around the plant clean and changing the substrate regularly can also help maintain the health of the orchid.
Orchids are beautiful plants that can bring a unique beauty and elegance to your home. Repotting orchids is an essential part of their care to ensure that they have healthy growth and longevity. With proper care and regular repotting, you can ensure that your orchids will bloom and thrive beautifully for many years.
