How to Fix Over Fertilized Plants and Revive Them
How to Fix Over Fertilized Plants?
To fix over-fertilized plants, the first step is to remove the excess nutrients from the growing medium.
If the over-fertilization is from water-soluble fertilizer, leaching the soil with water can help remove the excess nutrients.
For over-fertilization from Controlled Release Fertilizers (CRFs), regular leaching is necessary.
It is recommended to apply CRFs at a medium rate and supplement with water-soluble fertilizer if needed.
Preventive monitoring is crucial to detect and address nutrient issues before they weaken the plants.
Regularly checking injector flow and application rates with EC meters ensures correct fertilizer application rates.
Managing fertilizer application rate based on crop requirements through testing the growing medium’s EC, pH, and nutrient content is important.
Additionally, using PRO-MIX® BIOFUNGICIDE™ + MYCORRHIZAE™ products can help reduce disease and mitigate the effects of fertilizer imbalances.
Signs of over-fertilization include root burn, blackened or brown appearance of roots, limp texture, and excessive foliage growth but reduced blossoming.
To treat over-fertilized plants, increased watering to leach out excess fertilizer is necessary.
Manual removal of excess fertilizer is possible for container plants, and removing affected plant parts helps the rest of the plant grow properly.
It is important to track the plants’ progress after implementing treatment methods.
If the plants do not recover, severe root rot and foliage damage may require removing and replanting.
Chemical methods to balance nutrient levels should be avoided, and flushing out excess nutrients with water is the most effective method.
It is recommended to only use as much fertilizer as needed to prevent fertilizer burn.
Dividing fertilizer applications into small amounts over equal periods or using slow-release fertilizers can help prevent over-fertilization.
Adequate irrigation after fertilizing is crucial, and organic fertilizers have a lower chance of causing fertilizer burn.
Overall, over-fertilized plants can recover with proper care, including flushing the soil with water, adjusting watering schedules, and providing adequate sunlight.
It is important to note that even organic fertilizers can lead to over-fertilization and harm plants if applied in large quantities.
Excessive fertilization can cause nutrient imbalances, nutrient toxicity, and burning of plant roots and foliage.
Therefore, it is crucial to fertilize lawns every 6-8 weeks based on specific needs rather than every two weeks.
A 16-16-16 fertilizer, which has equal proportions of nitrogen, phosphorus, and potassium, is a balanced fertilizer commonly used for various plants and crops.

Did You Know?
1. Over-fertilization can cause a condition called “fertilizer burn,” where excessive nutrients damage the plant’s roots and leaves, resulting in wilting or yellowing foliage.
2. An effective remedy for over-fertilization is to flush the plant’s soil with water. This helps to remove the excess nutrients and restore the soil’s balance, giving the plant a chance to recover.
3. Sometimes, over-fertilized plants may exhibit symptoms that resemble nutrient deficiencies. This can be misleading, as adding more fertilizer would only worsen the situation. It is crucial to correctly identify the cause before attempting any remedies.
4. Prevent over-fertilization by carefully reading the instructions on the fertilizer packaging and strictly following the recommended dosage. Overdosing plants with fertilizer can lead to unnecessary stress and long-term damage.
5. Plants can show signs of over-fertilization even when using organic fertilizers. Although organic options may be less likely to cause immediate harm, it’s important to apply them correctly to avoid oversupplying nutrients to the plants.
Primary Causes Of Over Fertilized Plants
Over-fertilization in plants is primarily caused by two factors: over-watering and over-fertilization. When plants receive an excess of both water and nutrients, their roots become saturated and unable to absorb water effectively. This leads to root rot diseases that can seriously harm the plants.
Another cause of over-fertilization is under-fertilization. When plants do not receive enough nutrients, their growth slows down, making them more susceptible to diseases and insect attacks. This is why it is crucial to provide plants with the appropriate amount of fertilization to ensure healthy growth and resilience against potential threats.
Key Points:
- Over-fertilization is caused by over-watering and excessive nutrient use.
- Saturated roots lead to detrimental root rot diseases.
- Under-fertilization can result in stunted growth and increased vulnerability to diseases and pests.
By maintaining a balance and providing plants with the right amount of fertilizer, we can promote their health and fortify them against potential threats.
Correcting Under Fertilization
Under fertilization can be corrected by applying water-soluble fertilizer.
- Water-soluble fertilizers are easily absorbed by plants and provide quick delivery of necessary nutrients for growth.
- It is vital to carefully follow the instructions on the fertilizer package to ensure the correct amount is applied.
“Applying water-soluble fertilizer can effectively correct under fertilization. These fertilizers are easily absorbed by plants, delivering essential nutrients quickly. It is crucial to meticulously adhere to the instructions on the fertilizer package to determine the appropriate application quantity.“
Dealing With Over Fertilization From Water-Soluble Fertilizer
If the over fertilization is from water-soluble fertilizer, excess nutrients can be removed by leaching the growing medium with water. This involves thoroughly watering the plant to flush out the excess fertilizer. It is crucial to adjust future fertilizer applications to prevent further over fertilization.
Addressing Over Fertilization From Controlled Release Fertilizer (Crf)
Over-fertilization from Controlled Release Fertilizers (CRFs) can weaken plants and make them more susceptible to diseases. To avoid this problem, it is advisable to apply CRFs at a moderate rate and, if needed, supplement them with water-soluble fertilizer. Additionally, regular leaching should be done to remove any excess nutrients that may be released slowly from the CRFs.
Key points to remember:
- Over-fertilization with CRFs can harm plants and increase their vulnerability to diseases.
- Apply CRFs at a moderate rate and use water-soluble fertilizer as a supplement if necessary.
- Regular leaching is essential to eliminate any excess nutrients released slowly from the CRFs.
“Over fertilization from Controlled Release Fertilizers (CRFs) can lead to weak plants and increased vulnerability to diseases.”
Keep in mind the following to avoid these issues:
- Apply CRFs at a medium rate and use water-soluble fertilizer if needed.
- Regular leaching is crucial to remove excess nutrients released slowly from the CRFs.
Importance Of Preventive Monitoring For Nutrient Issues
Preventive monitoring is crucial to detect and address nutrient issues before they weaken the plants. It is essential to regularly check injector flow and application rate using Electrical Conductivity (EC) meters to ensure correct fertilizer application rates. This will help maintain a good balance of nutrients for optimal plant growth.
Signs And Treatment Of Over-Fertilized Plants
Signs of over-fertilization include:

Frequently Asked Questions
Can plants recover from fertilizer burn?
Plants have the potential to recover from fertilizer burn, although the extent of recovery largely relies on the health of their roots. If the roots have been significantly damaged, the chances of crop revival are typically low. However, one effective method to rectify fertilizer burn is through a process of flushing the affected plants with water for approximately a week. By doing so, excessive nutrients are flushed out and leached below the root zone, helping create a safer soil environment for the crops to rejuvenate.
How long does it take for a plant to recover from over fertilization?
After taking the necessary steps to remove excess fertilizer and flush out the soil, the recovery period for a plant that has been over-fertilized varies. The timeline differs for each plant species, but generally, it takes a couple of weeks for the plant to regain its vitality. However, for some plants, it may take longer or require additional measures such as replanting in new soil. It is crucial to monitor the plant closely during this time and provide appropriate care to aid in its recovery.
How do you know if you over fertilize your plants?
One way to determine if you have over-fertilized your plants is to look for signs of nutrient imbalance. This could manifest as poor growth, stunted or distorted leaves, or a decrease in flowering or fruiting. Additionally, you may notice an accumulation of excess fertilizer salts on the soil’s surface or in the water drainage, indicating that the plants are not absorbing all the nutrients. Monitoring the health and growth of your plants closely and observing any abnormal symptoms can help you identify if you have over-fertilized them.
Can fertilizer cause root rot?
Overuse of fertilizer can indeed lead to root rot in plants. When plants receive excessive amounts of fertilizer, it can cause soft and leggy growth, which weakens their overall structure. Additionally, the high salt levels from fertilizers can burn delicate root tips, further compromising the plant’s health. These weakened conditions make plants more vulnerable to diseases, including root rot. Therefore, it is crucial to use fertilizer in moderation and ensure proper balance to avoid detrimental effects on plant roots.
