Rescue your Aloe Vera from root rot with this essential guide to diagnosis, treatment, and prevention!
Aloe vera is a popular houseplant known for its healing properties and versatility. The gel inside the leaves can be used to treat minor burns help heal wounds, and soothe irritated skin. Aloe vera plants are generally easy to care for but they can develop root rot if overwatered. Root rot is one of the most common problems when growing aloe vera plants. Understanding what causes it and how to prevent it will help keep your aloe vera healthy and thriving.
What Causes Rot in Aloe Vera Plants?
Root rot in aloe vera is caused by overwatering and soggy soil. Aloe vera plants should be watered deeply but infrequently, allowing the soil to fully dry out between waterings. They do not like to sit in wet soil. If the soil stays soggy for too long, the roots are deprived of oxygen. This creates an environment where fungal diseases can take hold, causing the roots to turn brown and mushy. As root rot worsens, it spreads up into the leaves, causing them to turn brown, wilt, and collapse.
Several factors can contribute to overwatering and increase the risk of root rot
-
Using too small of a container: When an aloe vera plant is potted in a container that is too small, the soil stays wet for longer periods. Choose a pot that is just slightly larger than the root ball or plant.
-
Dense or heavy potting soil: Soil that is very dense holds onto moisture longer. Use a well-draining potting mix for aloe vera plants.
-
Lack of drainage holes: Pots without drainage holes do not allow excess water to drain away from the roots. Always use containers with adequate drainage for aloe vera.
-
Overwatering Watering too frequently and not allowing the soil to dry between waterings is the most common cause of root rot
-
Excess humidity: High humidity prevents moisture from evaporating from the soil, keeping it wet longer.
Preventing Root Rot in Aloe Vera
Luckily, root rot can be easily avoided by following proper watering practices and providing the right growing conditions. Here are some tips for preventing root rot in aloe vera plants:
-
Water deeply and infrequently. Allow the soil to completely dry out before watering again. The timing will vary based on factors like pot size, temperature, and humidity. But a general rule of thumb is to water every 2-3 weeks.
-
Check soil moisture. Stick your finger in the soil to gauge moisture before watering. If the soil is still damp 1-2 inches below the surface, hold off on watering.
-
Provide fast drainage. Use containers with drainage holes so excess water can easily drain away. Add perlite, gravel, or other amendments to improve drainage in heavy potting mixes.
-
Give bright light. Aloe vera thrives in bright, direct light. Low light causes the plant to require less frequent watering.
-
Keep humidity low. Prevent moisture from building up in the soil by keeping indoor humidity below 60%. Good air circulation from fans helps too.
-
Avoid overcrowding. Make sure plants aren’t packed too tightly together. This restricts air flow and slows soil drying.
-
Monitor for signs. Catch root rot early by watching for wilting and collapsing leaves. Check roots if rot is suspected.
-
Let soil completely dry out. If you notice signs of rot, allow the soil to dry out completely before watering again. This helps stop the spread of fungal diseases.
Fixing Root Rot in Aloe Vera Plants
If aloe vera plants are overwatered and develop root rot, take action right away. Removing damaged roots and drying out the soil can stop rot from spreading further. Here’s how to treat root rot in aloe vera:
-
Unpot the plant. Gently remove the entire plant from its container and loosen the root ball.
-
Inspect roots. Cut away any brown, mushy roots using sterilized shears. Healthy roots are firm and white/cream colored.
-
Rinse roots. Gently wash remaining healthy roots to remove diseased root particles. Allow roots to air dry for 1-2 days.
-
Repot in fresh mix. Fill a new container that has drainage holes with well-draining potting mix, then replant the aloe vera.
-
Hold off on watering. Do not water right away. Allow the soil to completely dry out before resuming normal watering habits.
-
Move to brighter location. Ensure the plant gets ample sunlight to discourage rot from returning.
-
Apply fungicide drench. For severe cases, use a fungicide drench like neem oil on the roots after repotting to kill lingering fungi.
With attention to proper watering, plenty of light, and fast-draining soil, it is possible to avoid the hassle of root rot and keep aloe vera plants thriving. But even if they show signs of rot, the damage can often be reversed by taking swift action to improve drainage, dry out the soil, remove dead roots, and repot in fresh mix. Following the fundamental growing conditions aloe vera prefers will lead to many years of happy, healthy plants.
Frequently Asked Questions About Aloe Vera Root Rot
Many plant parents have questions when their aloe vera plant develops root rot. Here are answers to some commonly asked questions:
Can aloe vera plants recover from root rot?
Yes, aloe vera plants can often recover from root rot if more than 50% of the root system is still healthy. Remove all damaged roots, allow the remaining healthy roots to dry out, repot in fresh dry soil, and hold off on watering. The plant should regrow new healthy roots.
What does healthy aloe vera root look like?
Healthy aloe vera roots are firm, plump, and white or cream colored. Brown, mushy roots that are easily pulled away from the plant are diseased. Soft black roots may indicate root rot.
How much sunlight does aloe vera need to prevent root rot?
Aloe vera does best with lots of bright, direct sunlight – ideally 4-6 hours per day or more. Low light and infrequent watering is a recipe for root rot.
Can I cut off the mushy part of an aloe vera leaf?
Yes, you can trim away brown mushy sections of aloe vera leaves. Just be sure to sterilize your shears to prevent spreading disease. Allow the cut end of the leaf to callous over before watering again.
Should I water aloe vera less in winter?
Yes, aloe vera requires less frequent watering in winter when sunlight hours and temperatures are reduced. It may only need water every 4-6 weeks in colder months versus every 2-3 weeks in summer.
Enjoying a Thriving Aloe Vera Houseplant

Provide this succulent with bright light, infrequent but thorough watering, well-draining soil, warm temperatures, and low humidity. Avoid overwatering, and quickly resolve any signs of root rot. With the right growing conditions, your aloe vera will produce healthy leaves full of gel that can be used to make cosmetics, drinks, medicine, and more! A thriving aloe vera plant adds beauty to any indoor space while also providing practical benefits for your health and skin.
The Falling Plant
If your Aloe Vera starts leaning like a tipsy party guest, its another sign of trouble. Root rot can cause the plant to lose its support system, making it topple over.
Remember, catching root rot early is key. So, keep a keen eye (and nose) on your Aloe Vera. If you spot any of these symptoms, its time to roll up your sleeves and get to work.
Symptoms of Aloe Vera Root Rot
Aloe Vera root rot is a sneaky little devil. Its like the plant version of a cavity, rotting away at the roots while the plant tries to keep up appearances. Lets dive into the telltale signs that your Aloe Vera is battling this underground menace.
First off, wilting. Healthy Aloe Vera leaves are plump and firm, like a well-stuffed taco. When root rot hits, the leaves droop, looking more like a sad, soggy burrito.
Next, yellowing. Aloe Vera leaves should be a vibrant green, like a fresh salad. Root rot, however, turns them a sickly yellow, akin to overcooked broccoli.
Finally, mushy roots. Healthy roots are firm and robust. Rotten roots, on the other hand, have the consistency of overcooked pasta. Theyre slimy, easily detachable, and often a disconcerting brown-black color.
