Maintaining a lush, healthy lawn is a source of pride for many homeowners. Part of this maintenance involves applying weed and feed products to control weeds and fertilize the grass. However, there’s often confusion about the best practices for applying these products, particularly regarding lawn height and preparation. In this article, we’ll delve into the details of whether you should cut your grass before applying weed and feed, exploring the benefits, potential drawbacks, and expert recommendations to help you make an informed decision.
Understanding Weed and Feed Products
Before discussing the preparation steps for applying weed and feed, it’s essential to understand what these products are and how they work. Weed and feed products are combination lawn care products designed to control weeds and fertilize the grass in a single application. They typically contain a blend of herbicides to kill weeds and fertilizers to promote healthy grass growth. The herbicides target broadleaf weeds, and the fertilizers provide essential nutrients such as nitrogen, phosphorus, and potassium.
Types of Weed and Feed Products
Weed and feed products come in various formulations, including granular, liquid, and slow-release forms. The choice of product often depends on personal preference, lawn type, and the specific weed control needs. For example, granular products are easy to apply and provide a quick response, while slow-release formulations offer longer-lasting fertilizer benefits.
Importance of Following Instructions
It’s crucial to follow the manufacturer’s instructions when applying weed and feed products. This includes adhering to the recommended application rates, timing, and post-application care.

What is the purpose of cutting the grass before applying weed and feed?
The primary purpose of cutting the grass before applying weed and feed is to ensure that the product reaches the soil and the weeds effectively. When the grass is too long, it can prevent the weed and feed from coming into contact with the soil, reducing its efficacy. By cutting the grass, you are creating a clear path for the product to reach the roots of the weeds, allowing it to work more efficiently. This is especially important for weeds that grow close to the ground, as the herbicide needs to be able to reach the leaves and roots of the weeds in order to kill them.
Additionally, cutting the grass before applying weed and feed can also help to prevent the product from being wasted. If the grass is too long, the weed and feed can become trapped in the blades of grass, reducing the amount that actually reaches the soil. By cutting the grass, you can ensure that the product is distributed evenly and that it reaches the areas where it is needed most. It’s also important to note that the recommended mowing height before applying weed and feed can vary depending on the type of grass and the product being used, so it’s always a good idea to check the instructions on the label for specific guidance.
How short should I cut my grass before applying weed and feed?
The ideal mowing height before applying weed and feed can vary depending on the type of grass and the product being used. As a general rule, it’s recommended to cut the grass to a height of 2.5 to 3 inches before applying weed and feed. This height allows for the product to reach the soil and the weeds, while also preventing the grass from becoming too stressed. Cutting the grass too short can cause damage to the blades and roots, making it more susceptible to disease and pests.
It’s also important to consider the type of grass you have when determining the ideal mowing height. For example, if you have a cool-season grass such as Kentucky bluegrass or perennial ryegrass, you may want to cut it to a height of 2.5 to 3 inches. On the other hand, if you have a warm-season grass such as Bermudagrass or zoysiagrass, you may want to cut it to a height of 1 to 2 inches. It’s always a good idea to check the instructions on the label of the weed and feed product for specific guidance on mowing height, as some products may have different recommendations.
Can I apply weed and feed without cutting my grass first?
While it is technically possible to apply weed and feed without cutting the grass first, it is not recommended.

Yes, you can use a lawn mower with a bag attachment to pick up clippings before applying weed and feed. In fact, this is a good idea, as it can help to prevent the clippings from interfering with the application of the product. When using a lawn mower with a bag attachment, it’s recommended to set the mower to the recommended height for your specific type of grass, and to collect the clippings in the bag. This will help to ensure that the weed and feed can reach the soil and the weeds effectively, and reduce the risk of the product being wasted.
It’s also a good idea to use a lawn mower with a mulching attachment, which can help to chop the clippings into small pieces that can be left on the lawn. This can help to act as a natural fertilizer, and reduce the need for additional nutrients. However, if you do choose to use a mulching attachment, it’s recommended to wait until the clippings have had a chance to decompose before applying weed and feed. This will help to ensure that the product can reach the soil and the weeds effectively, and reduce the risk of the clippings interfering with the application of the product.
Will rain after applying weed and feed affect its efficacy?
Yes, rain after applying weed and feed can affect its efficacy. Most weed and feed products require a certain amount of time to dry and be absorbed into the soil before they can start to work effectively. If it rains shortly after application, it can wash the product off the grass and into the storm drains, reducing its efficacy. Additionally, rain can also cause the product to be diluted, reducing its concentration and making it less effective.
However, some weed and feed products are designed to be rain-fast, meaning that they can withstand rain and still remain effective. If you do experience rain after applying weed and feed, it’s not the end of the world. The product may still be effective, although its efficacy may be reduced. To minimize the impact of rain, it’s recommended to apply weed and feed during calm, dry conditions, and to avoid applying it before heavy rain is forecasted. It’s also a good idea to follow the instructions on the label of the product, and to take any necessary precautions to ensure that the product is applied correctly and safely.
