Overpotting is the use of a pot that is too large for a plant’s roots, which can be detrimental to the plant. Common faults include overpotting during the wet season, not taking enough care in dividing plants, and placing the back end of a pot on the back end. Orchids are vulnerable and crucial in floriculture, but they also face common pests.
Over-fertilizing orchids can do more harm than good, as many enthusiastic growers make the mistake of applying too much fertilizer too often. Burying all the roots can suffocate the plant, leading to poor health and fewer blooms. Instead, use a loose, well-draining orchid mix, like bark or sphagnum.
Overpotting is a problem in large pots that hold a huge volume of potting mix, as well as in very tall or deep pots, especially if the plant’s roots don’t grow too deep. Orchids are drama queens, and they will show you if they’re over or under watered. Over-watered orchids have yellow leaves that feel mushy and may even fall off.
To detect overpotting, remove the orchid from its original pot, clean off the old compost, and open up the orchid. In an overpotted plant, there are two issues: the overly wet potting mix causing the roots to rot and the lack of roots to support all the leaves on the plant.
The only reason “over potting” causes plant death is because the correct moisture amounts were not maintained. Leaf yellowing, leaf browning, leaf fall, wilting, stunted growth, bronzing on evergreens, and soggy compost on the surface of the pot can indicate that the soil will remain wet too long and cause root rot issues.
It is easy to tell if your orchid’s pot has absorbed too many fertilizer salts by turning black or brown on the orchid’s root tips that touch the pot.

Why is my orchid dying after repotting?
Orchid root rot can be caused by poorly drained potting mix, which can decompose over time and absorb fertilizer salts, leading to an unhealthy potting mix. Traditional potting mixes are often too dense for orchids, which are sensitive to water. Orchids prefer airflow, which circulates moisture around them and prevents harmful bacteria from growing. Orchids are typically from tropical climates and thrive in high humidity, but airflow is essential for maintaining their health. Therefore, it’s crucial to use a well-draining potting mix for orchids.
What is over fertilizing?
Fertilizer burn is a common sign of over-fertilization, characterized by dry, yellow, or brown leaves and grass blades. It’s caused by salts remaining in the soil after water has evaporated or drained. If the correct amount of fertilizer is applied, these salts don’t cause issues. However, when too much fertilizer is applied, they have less chance to disperse, drawing moisture away from roots and damaging crops or turf. Nitrogen salts are usually the main culprits. Identifying fertilizer and nitrogen burn can be challenging as symptoms often mimic nutrient deficiency. If you have doubts, test the soil.
What killed my orchid?
Overwatering is the leading cause of orchid mortality, as it can cause root rot in orchids with thick, fleshy roots. To avoid this, ensure the potting medium is loose and well-draining, and allow it to dry slightly between waterings. Overwatering symptoms include yellow, soft leaves and black, mushy roots.
Underwatering poses risks to orchids, resulting in dehydrated, wrinkled leaves and stunted growth. Consistent watering schedules, adjusted for factors like medium, pot size, and environmental conditions, are essential to keep the orchid hydrated but not waterlogged.
Light is crucial for orchids, affecting their photosynthesizing and blooming. Different orchids have varying light requirements, with Phalaenopsis preferring moderate indirect light and Cattleya thrivering in brighter conditions. Insufficient light results in dark green, limp leaves and a lack of blooms. Placing the orchid in a spot with ample indirect sunlight or using grow lights can ensure it receives the light it needs without the risk of sunburn.
Can you use potting soil over?
Reusing soil is generally not recommended due to the presence of soilborne pathogens, especially if plants have died from bacterial, fungal, or viral diseases. However, if the plants were healthy, it is generally acceptable to reuse the potting soil. To ensure soil cleanliness, sterilize it through solarization in the sun or heating it in an oven or microwave. Remove dead plants and dump the used soil into a bin to remove large roots and insects. If sterilized with the sun, place the soil in strong, black plastic bags or containers and leave them in the sun for four to six weeks.
What is over potting?
The term “overpotting” is used to describe the practice of placing a containerized plant in a larger container, which can lead to adverse effects on the plant’s health. While not inherently problematic, overpotting can lead to complications when the plant is not exhibiting robust growth or when excessive irrigation is a concern. In the short term, the plant should appear to thrive following the potting process.
What happens if you overwater orchids?
Watering your orchid every 7 to 11 days, especially when the mix is dry, is essential to prevent damage and prevent overwatering, which can lead to crown rot, root rot, and other infestations. Watering in the morning is recommended as nighttime watering can leave water sitting for a period. Additionally, consider the temperature of your house, as high thermostats may cause the orchid to grow in summer.

Does repotting stress orchids?
Avoid repotting flowering orchids due to potential stress on flowers and buds. Wait for the plant to finish blooming before repotting. Use a bark potting mix in a clay or plastic container for proper ventilation and drainage. Repot when the plant is actively growing, looking for new roots or shoots. If a young plant is not mature enough to flower, repot in spring. Orchid roots require air and water for growth.
When should you not repot an orchid?
Repotting an orchid is not recommended when it is in bloom, as it can cause stress and damage to the plant. Instead, it is recommended to repot it every one to two years to maintain its health and growth. Repotting helps maintain the potting media in good shape, allowing for rapid drainage and root aeration. If you’re unsure if repotting is necessary or if you’re hesitant to do so, there are three telltale signs that indicate it’s time to repot your orchid:
- The orchid is in bloom, and it’s time to repot.
- The potting media is in good shape, allowing for rapid drainage and root aeration.
- The orchid is ready for repotting.
Do orchids like to be crowded?
Orchids prefer small pots, weaving their roots through compost. However, they eventually run out of space when their roots push the plant up above the rim or reach out into the air, indicating it’s time to re-pot. Talk around the Garden discusses orchids and answers the question “How to repot my orchid?” Most orchids can be repotted when new, every year or two, or when crowded roots push up and out of the pot.
What’s killing my orchid?
Orchid deaths are primarily caused by root loss due to over or under-watering, along with pests and diseases. Mistakes can occur in orchid growing, such as overwatering, underwatering, overfertilizing plants that are salt-intolerant, or giving too much sun to one plant. Some mistakes may be due to ignorance or inappropriate advice.
The success of orchid growing relies on experience, which takes time and can be learned through reading. However, there may be unique conditions in your environment that may not be discussed, leading to unexpected sunburns. Until you encounter such a rare condition, you may not know you are putting a plant in danger.
Experiencing is crucial in identifying and avoiding problems, as it helps you anticipate and avoid potential issues. As you gain more experience, the more mistakes you make, the more problems you can anticipate and avoid. As the saying goes, “it must be seen to be appreciated”.
What is bad for orchids?
It has been demonstrated that elevated levels of air pollution, including ozone and sulfur dioxide, can have a profound impact on orchids. Of particular concern is the effect of ethylene, which can result in damage to buds and flowers, yellowing of leaves, and premature leaf drop.
