Do you notice that your aloe vera or any other type of aloe is losing vitality? I assure you, you're not the only one facing this problem. Although they're considered hardy and easy-care plants, aloes can be affected by various causes that compromise their health, and without proper management, they can even die. If you're wondering, What to do if an aloe plant is dyingHere's the definitive guide, based on both growers' experience and the most comprehensive and up-to-date advice in the industry.
Main causes of aloe death
Identify the exact cause of the discomfort In your aloe vera, this is the first step to saving it. Below are the most common factors:
Excess water and root rot
El excess irrigation This is the most common and dangerous mistake. Aloes are succulents adapted to withstand drought, so constantly wet soil ends up suffocating their roots. If the leaves become soft, transparent, or yellowish, the roots may be rotting. Furthermore, if the substrate smells bad, it's a sure sign of a rot problem.
Lack of water and dehydration
Unlike the previous case, too little watering This can also endanger the aloe. The plant begins to absorb water from its own leaves, which become flattened, wrinkled, and dry. The tips may turn brown or dry, and the soil will be completely dehydrated.
Inadequate light
Lighting is key. Aloe requires plenty of sunlight, preferably direct sunlight for several hours a day. However, if it's not acclimated and is exposed to direct sunlight after being in the shade (or indoors), its leaves are likely to burn and turn brown. On the other hand, a lack of light will cause slow growth, weak leaves, abnormal elongation, and loss of color.
Cold, frost and temperature changes
Aloes tolerate cool temperatures, but They do not tolerate frost well Nor prolonged periods of intense cold. The leaves can become soft, translucent, and eventually rot. A one-time event such as hail or snow also leaves immediate aftereffects, irreversibly damaging the above-ground parts of the plant.
Substrate and drainage problems
A poorly drained, compacted, or depleted substrate blocks root development and the passage of water and air. Aloe needs a loose, light and airy soil, with excellent drainage. An old or compacted substrate makes it difficult for water to absorb and encourages the development of fungal diseases.
Nutritional deficiencies
If aloe is left in the same substrate for a long time without fertilizer, it may show deficiencies. The leaves may appear pale green, with little vigor and poor growth. Occasional application of mild fertilizers can reverse this situation, but it should never be overdone, as excess salts can damage the roots.
Presence of pests and diseases
Mealybugs, aphids, mites or whiteflies can significantly weaken aloe plants, especially if they're already stressed by other factors. Additionally, fungi attack if aloe remains wet for too long.
Pot problems
Many times the problem is in the pot size or lack of repotting. A pot that's too small impedes root growth and can cause water to drain without adequately hydrating the substrate, especially if the soil is very compacted.
How to save a dying aloe plant
Once the cause has been identified, it is essential to act quickly and apply the most appropriate treatment. Not all solutions are suitable for all problems: Each situation requires its own specific approach.
Step 1: Complete assessment of the plant's condition
- Examine the leaves: Check if they are soft, dry, wrinkled, stained, discolored, or burnt.
- Look at the base: Look for signs of rot, fungus, or weakness.
- Check the land: Check if it is waterlogged, very dry, compacted, or infested with pests.
- Analyze the environment: Observe whether it receives too much or too little light, whether it is exposed to drafts or sudden changes in temperature.
Step 2: Adjust watering according to actual needs
- If there is excess water: Stop watering immediately. Remove the plant from the pot, remove any wet or deteriorated soil, and cut off any rotten roots. Let the plant dry for a couple of days in a shaded, well-ventilated area before repotting it into a new, dry potting medium. Use a specific fungicide to prevent fungal attacks.
- If there is a lack of water: Use the immersion irrigationPlace the pot in a large container of water, allowing the soil to be completely moistened from bottom to top for 30 to 60 minutes. Remove the plant and let it drain until it stops dripping. Repeat only when the soil feels dry to the touch.
Step 3: Ensure adequate lighting
- If the aloe has been sunburned: Move it to a bright area, but not in direct sunlight. Wait for it to sprout new leaves and gradually expose it to sunlight, starting with 1-2 hours a day and gradually increasing.
- If it was in shadow: Move the plant to a location where it receives 4 to 6 hours of indirect sunlight, gradually increasing the exposure. Avoid sudden changes to avoid further stressing the plant.
Step 4: Protect from cold, wind or sudden changes
- In case of damage due to low temperatures: Move the plant indoors to a bright, draft-free room. Trim any soft or rotten leaves. Do not water until the soil is completely dry and the plant shows signs of recovery.
Step 5: Transplanting and choosing the right pot
- Transfer the plant to a suitable sized pot. if the roots are sticking out of the drainage holes or the soil is very compacted.
- Choose a pot with good drainage, slightly larger than the current one to promote root development.
- Use a specific substrate for succulents or mix your own soil with a minimum of 30-40% coarse sand, perlite, or gravel to improve drainage.
- If the aloe has suckers, carefully separate them and plant them individually, making sure each one has enough roots.
Step 6: Pruning and removing damaged leaves
- Remove all dry, soft or rotten leaves with clean, disinfected scissors to prevent the spread of disease and stimulate new growth.
- Do not remove leaves that still retain some color and firmness: they may recover.
Step 7: Light fertilization and nutritional care
- Apply a mild fertilizer specific for succulents during the active growing season, always respecting the recommended doses.
- Avoid overfeeding, which can cause salt buildup and harm roots.
Step 8: Pest and disease control
- Periodically inspect the underside of the leaves To detect mealybugs, mites, or aphids. Eliminate pests with soapy water, natural oils, or mild insecticides if necessary.
- Keep the plant clean, avoiding accumulated dust that attracts pests.
Step 9: Patience and follow-through
- Aloe vera's recovery can be slow. Don't give up if you don't see immediate results. As long as you see new leaves or a firmer appearance, continue with consistent care.
- Avoid moving the plant or repotting it repeatedly, as this causes stress and delays its recovery.
Common mistakes in aloe vera care
- Overwatering for fear of drought: Keep in mind that aloe tolerates a lack of water better than excess. Always water when the soil is dry to the touch, never as a weekly routine.
- Using saucers under the pot: Do not leave standing water under the pot, as this will encourage waterlogging even if the substrate drains well.
- Do not transplant from time to time: Repot your aloe every 2 to 3 years or when you notice growth has stopped.
- Improper indoor location: If you keep aloe indoors, always look for the sunniest spot possible, near a south- or east-facing window.
- Ignoring stress symptoms: Act at the first sign of decay or brown, yellowish or stained color.
Extra tips for optimal aloe vera maintenance
To ensure your aloe is always healthy after a crisis, keep these tips in mind, in addition to the previous ones:
- Check roots and substrate periodically to anticipate problems of rot or lack of space.
- During the colder months, reduce watering frequency to a minimum.
- Avoid using lime water for irrigation; rainwater or filtered water is better.
- Provide adequate ventilation to avoid overly humid environments.
- Take your aloe outside when the temperature allows., as it will grow much better with fresh air and direct sunlight.
With proper care and following all these steps, whether your aloe is affected by overwatering, lack of light, pests, or environmental stress, its chances of recovery are very high. The key lies in observation, patience, and respecting the plant's natural needs. If you act quickly at the first symptoms and adapt your care, your aloe will grow strong and healthy again, and you can even multiply your plants by separating healthy offspring.
