Rescue your Aloe Vera from root rot with this essential guide to diagnosis, treatment, and prevention!
Aloe plants are popular houseplants known for their ease of care, medicinal properties, and unique appearance. However, even these hardy succulents can fall victim to root rot – a common fungal disease that can quickly kill aloe plants if left untreated. In this article, we’ll explore the causes of aloe root rot, signs to watch for, and solutions to prevent or treat this problem in your aloe plant.
What Causes Root Rot in Aloe Plants?
Root rot in aloes is most often caused by overwatering. Aloe plants prefer infrequent but deep watering allowing the soil to fully dry out between waterings. Sitting in wet soil for too long promotes fungal growth and causes roots to rot. Other factors that can lead to root rot include
-
Poor drainage – Excess moisture gets trapped in soil without proper drainage. Always use pots with drainage holes.
-
High humidity – Consistently moist air also keeps soil too wet
-
Compacted soil – Densely packed soil prevents water from draining properly.
-
Unsuitable potting mix – Cheap mixes without amendments to improve drainage.
-
Cross contamination – Introducing fungus from infected plants or soil.
-
Pests like fungus gnats spread fungal spores and damage roots.
Signs and Symptoms of Root Rot
Watch for these common signs that your aloe may have root rot:
- Dark, mushy, foul smelling roots
- Lower leaves turning yellow or brown
- Wilting, drooping leaves
- Soft, translucent leaves
- White fungal growth on soil or roots
- Presence of fungus gnats flying around soil
The sooner you catch root rot, the better chance you have of saving your plant. At advanced stages, roots may be entirely black and dead.
How to Prevent Aloe Root Rot
Luckily, it’s easy to avoid root rot in your aloe with proper watering technique and care. Follow these tips:
- Allow soil to dry out between waterings. Test with finger.
- Water deeply, until it drains from holes in pot.
- Use fast-draining cactus/succulent soil.
- Add perlite or gravel to soil to improve drainage.
- Water less in winter when aloe is dormant.
- Ensure pot has drainage holes to prevent standing water.
- Avoid getting water on leaves to discourage disease.
- Provide sunlight and air circulation.
- Repot when rootbound into pot just one size larger.
- Sterilize shears and pots to prevent spreading disease.
- Check for pests like fungus gnats that damage roots.
How to Treat Root Rot in Aloe Plants
If caught early, aloes can recover from root rot. Follow these steps:
- Unpot the aloe and inspect roots. Remove all dark, mushy roots.
- Disinfect remaining healthy roots with fungicide or diluted bleach solution.
- Cut off any rotted lower leaves or base of plant if needed.
- Allow base to callous over for several days before replanting.
- Repot in sterile cactus mix with perlite in a container with drainage.
- Water sparingly at first until new growth appears.
For severe cases with total root loss, cut off all dead roots and plant the healthy leaves in dry soil. New roots should generate along the stems in a few weeks. Take care not to overwater while roots regenerate.
When to Seek Professional Help
If the majority of your aloe’s roots are damaged or symptoms are advanced, you may need professional help to save it. A plant pathologist can test for pathogens and provide fungicide treatments. However, severely declining aloes often can’t be revived. Starting over with a fresh, healthy plant may be better.
Catching and addressing root rot early gives the best chance of recovery. At the first sign of trouble, inspect roots and take action. With proper aloe vera plant care, root rot can be successfully prevented or managed if it does occur in your succulents. Follow the tips above to help avoid this frustrating disease.

The Smell Test
Now, for the smell. If your Aloe Veras soil smells like a forgotten gym bag, youve got a problem. Foul odor is a classic sign of root rot. Its the result of fungi and bacteria throwing a party in the waterlogged soil.
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.
