What Causes Fertilizer Burn?
Fertilizer burn occurs when plants are exposed to excessive amounts of fertilizers or when the fertilizers are not properly diluted. The main cause of fertilizer burn is an imbalance of nutrients, particularly nitrogen, phosphorus, and potassium, commonly referred to as NPK.
When too much fertilizer is applied or when it is concentrated in one area, the high levels of nutrients overwhelm the plants’ abilities to absorb and process them. This excess causes the plant’s cells to become dehydrated, leading to damage and death of the affected tissues.
There are several factors that can contribute to fertilizer burn:
- Over-fertilization: When too much fertilizer is applied, the plant cannot absorb all the excess nutrients, leading to burn.
- Improper dilution: Fertilizers need to be mixed with water or spread evenly to avoid concentrated spots that can cause burn.
- Application during hot weather: Fertilizing plants during hot, dry weather conditions can increase the risk of burn as the excessive heat accelerates the uptake of nutrients.
- Application near the stem or foliage: Direct contact between fertilizer and the stem or foliage can cause burns, as the concentrated nutrients can directly affect the sensitive tissues.
- Using the wrong type of fertilizer: Different plants have specific nutrient requirements, and using the wrong type of fertilizer can result in nutrient imbalances and burn.
It is crucial to understand these causes to prevent fertilizer burn from occurring. Proper application methods, careful nutrient balance, and timing are key factors in keeping your plants healthy and avoiding the harmful effects of fertilizer burn.
Signs and Symptoms of Fertilizer Burn on Plants
Recognizing the signs and symptoms of fertilizer burn is crucial for early detection and effective treatment. Here are some common indicators to look out for:
