Will Starter Fertilizer Harm Existing Grass?
When it comes to lawn care, using starter fertilizer is a common practice to ensure that newly seeded or sodded lawns establish quickly and robustly. However, many homeowners wonder if applying starter fertilizer to their existing grass could potentially harm it. In this article, we will explore the potential risks and benefits of using starter fertilizer on established grass and provide some guidance on how to use it safely.
Understanding Starter Fertilizer
Starter fertilizer is a type of fertilizer designed to provide a quick boost of nutrients to young plants, such as seeds or transplants. It typically contains higher levels of phosphorus, which promotes root development and establishment. While starter fertilizer is beneficial for new lawns, it is essential to understand its impact on existing grass.
Risks of Using Starter Fertilizer on Existing Grass
1. Over-fertilization: Applying starter fertilizer to established grass can lead to over-fertilization, which can cause damage to the grass. Excessive nitrogen can stimulate excessive top growth at the expense of root development, making the grass more susceptible to pests, diseases, and drought.
2. Burn: If starter fertilizer is applied too heavily or in the wrong area, it can cause chemical burn on the grass. This can lead to brown patches and even the death of the grass in severe cases.
3. Imbalance in Nutrients: Starter fertilizer is formulated to provide a specific balance of nutrients for young plants. Applying it to established grass can disrupt the nutrient balance, potentially leading to nutrient deficiencies or toxicities.
Benefits of Using Starter Fertilizer on Existing Grass
While there are risks associated with using starter fertilizer on existing grass, there are also some potential benefits:
1. Promote Root Development: If you have recently added new plants or trees to your lawn, applying starter fertilizer can help them establish quickly by promoting root development.
2. Enhance Seed Germination: If you are overseeding your lawn, using starter fertilizer can help the seeds germinate more quickly and establish a strong root system.
How to Use Starter Fertilizer Safely on Existing Grass
To minimize the risks and maximize the benefits of using starter fertilizer on existing grass, follow these guidelines:
1. Read the Label: Always read the label on the fertilizer package to understand the recommended application rates and instructions.
2. Apply Sparingly: Use starter fertilizer sparingly on established grass. If you must apply it, use a lower dosage than what is recommended for new lawns.
3. Target Specific Areas: Apply starter fertilizer only to the areas where you have recently added new plants or trees or where you are overseeding.
4. Avoid Overhead Spraying: When applying fertilizer, avoid overhead spraying to prevent it from reaching existing grass or other plants that may not benefit from it.
In conclusion, while starter fertilizer can be harmful to existing grass if not used properly, it can also provide some benefits when applied carefully. By following the guidelines outlined in this article, you can use starter fertilizer safely and effectively to enhance the health and beauty of your lawn.
