Critical StageCrown rot develops, orchid struggles to absorb water, risk of death6+ weeksHigh chance of plant loss—try sphag-and-bag method to save any remaining healthy tissue

The first step in fixing root rot is recognizing it before it spreads too far. Many orchid owners only notice something is wrong when the leaves turn yellow or start wilting, but by then, the roots may already be severely damaged. A healthy Cattleya trianae should have firm, plump roots that are either green (when moist) or silvery-white (when dry). In contrast, rotten roots appear dark brown or black, feel mushy, and often emit a foul smell. If your orchid is showing signs of dehydration despite regular watering, root rot could be the culprit.

Carefully remove the orchid from its pot and inspect the roots to look for signs of root rot.If most of the roots are decayed and falling apart when touched, immediate action is needed. The sooner you detect root rot, the easier it is to save your orchid from irreversible damage. By learning to recognize these early warning signs, you’ll be able to intervene before it’s too late and prevent the issue from recurring in the future.

Quick Fix:

Examine the orchid’s roots after removing it from its pot.If they are dark, mushy, and smell bad, root rot has set in, and you must take action immediately.

Remove Rotten Roots Immediately

Once you’ve confirmed root rot, the next step is to trim off the infected roots before the disease spreads further. Rotten roots not only fail to absorb nutrients but also encourage bacterial and fungal growth, which can affect the remaining healthy roots. To remove them safely, use a sharp, sterilized pair of scissors or pruning shears. Sterilization is essential because using unclean tools can introduce new infections. Carefully trim away all mushy, black, or hollow roots, leaving behind only the firm, healthy ones.

As you trim, disinfect your scissors with isopropyl alcohol or a flame after every few cuts to prevent spreading any lingering pathogens. If too many roots are affected, your orchid may struggle to recover, but removing them is the only way to stop further decay. While it may seem drastic, this step is necessary to give your orchid a fighting chance at survival. Once you’ve removed the infected roots, you’re ready for the next crucial step—allowing the plant to dry before repotting.

Quick Fix:

✓ Use sterilized scissors to cut off all mushy, dark roots. This prevents the spread of bacteria and fungi, allowing your orchid to focus on growing new roots.

Let the Orchid Dry Out Completely

After trimming the rotten roots, it’s important to let your orchid dry out before repotting it. Root rot thrives in moisture, so repotting too soon could reintroduce harmful fungi or bacteria. Place your orchid on a paper towel in a well-ventilated area and allow it to air dry for at least 24 hours. This gives any remaining root wounds time to heal and reduces the risk of reinfection.

During this drying period, avoid misting or watering your orchid, as even a small amount of moisture can allow fungal spores to survive. If your orchid has very few roots left, you can also place it in an area with indirect light and good air circulation to encourage it to recover more quickly. Letting the plant dry properly is one of the simplest yet most effective ways to prevent root rot from returning.

Quick Fix:

✓ Let your orchid dry out completely for 24 hours before repotting. This prevents fungal reinfection and allows cut root surfaces to heal.

Repot in Fresh, Well-Draining Medium

Once your orchid is dry, it’s time to repot it in fresh, well-draining potting mix. Cattleya orchids are epiphytes, meaning they don’t grow in soil but instead need a bark-based mix that allows air to reach their roots. Using the wrong medium—such as regular potting soil or sphagnum moss—can trap excess moisture and lead to another round of root rot. The best mix for Cattleya trianae includes:

Orchid bark – Provides airflow and prevents water retention
Perlite – Enhances drainage and prevents compaction
Charcoal – Absorbs toxins and reduces bacterial growth

Choose a well-ventilated orchid pot with drainage holes to allow water to escape freely. When repotting, gently spread the roots in the new medium and avoid packing it too tightly. This encourages air circulation, which is essential for healthy root regrowth.

Quick Fix:

✓ Repot in a fresh bark-based mix and use a well-draining orchid pot to ensure proper aeration and moisture control.

Adjust Watering Habits

The number one cause of root rot in Cattleya orchids is overwatering. Unlike some other houseplants, orchids don’t need frequent watering. They thrive on the soak-and-dry method, which mimics their natural environment. Instead of watering on a set schedule, only water when the roots turn silvery-white—a clear sign they’re dry. If you water too soon, excess moisture can linger, creating the perfect breeding ground for rot-causing fungi.

Always water in the morning so any excess moisture has time to evaporate throughout the day. Using room-temperature water, soak the potting medium thoroughly and then let it drain completely. If you’re unsure whether to water, stick a wooden skewer into the potting mix—if it comes out damp, wait a few more days. This simple adjustment can dramatically reduce the risk of root rot in the future.

Quick Fix:

✓ Only water when roots turn silvery-white, not on a fixed schedule. This prevents excess moisture from accumulating and causing rot.

Provide Proper Air Circulation

One of the most overlooked aspects of orchid care is air circulation. Poor airflow creates a humid, stagnant environment where bacteria and fungi thrive, increasing the risk of root rot. In nature, Cattleya orchids grow attached to trees with constant airflow around their roots, preventing excess moisture buildup. You can mimic this environment indoors by ensuring good ventilation around your orchid.

If you grow your orchid in a greenhouse or an enclosed space, consider using a small fan to keep the air moving. Place your orchid in a spot with gentle, indirect airflow, but avoid strong drafts, as these can dry out the plant too quickly. Proper air circulation helps dry out excess moisture, prevents fungal growth, and encourages stronger root development.

Quick Fix:

✓ Improve air circulation by placing a small fan nearby or keeping orchids in a well-ventilated area to reduce excess humidity.

Use a Root Growth Booster

If your orchid lost many roots due to rot, it may struggle to absorb water and nutrients. A root growth booster can speed up the recovery process and encourage new root development. Products like kelp extract, orchid-specific rooting hormones, or vitamin B1 supplements can give your orchid the extra support it needs.

To use a root growth booster, soak the remaining healthy roots in a diluted solution for about 30 minutes before repotting. After repotting, you can mist the base of the plant with the solution every few days to stimulate new growth. This method helps your orchid bounce back faster and strengthens its resistance against future infections.

Quick Fix:

✓ Soak roots in a kelp extract or vitamin B1 solution to encourage strong, healthy root regrowth.
