Over-Fertilizing One of the biggest mistakes is applying too much fertilizer. While plants need nutrients, excess fertilizer can burn the roots, damage the soil, and even harm your plants. Always follow the recommended amount on the fertilizer label.
Using the Wrong Fertilizer Not all fertilizers are created equal. Different plants have different needs. For example, flowering plants may require a higher phosphorus level, while leafy vegetables need more nitrogen. Make sure to choose the right fertilizer for your specific plants.
Fertilizing at the Wrong Time Applying fertilizer at the wrong time can cause harm. For instance, fertilizing in late fall may stimulate growth that is vulnerable to winter stress. It’s best to fertilize during the growing season and avoid fertilizing when plants are dormant.
Skipping Soil Testing Fertilizing without testing the soil is like guessing in the dark. A soil test helps identify any nutrient deficiencies or imbalances, ensuring you apply the right type and amount of fertilizer. Skipping this step can lead to over or under-fertilization.
Neglecting Watering After Fertilizing Fertilizer needs to be watered in to prevent root burn and ensure nutrients are absorbed. Applying fertilizer without watering it in can cause the fertilizer to sit on top of the soil and not reach the roots, making it ineffective or harmful.
