Should You Fertilize Or Spray For Weeds First?

Explore effective gardening strategies: Learn why spraying for weeds before fertilizing ensures efficient nutrient delivery and minimizes waste, enhancing crop yield.

Table of Contents

Weeds pose a threat to crop yield as well as natural ecosystems. These unwanted plants take up space, nutrients, and water meant for the crops, which results in low production and quality. Plus, most of the weeds produce seeds and multiply at faster speeds and even survive in almost every adverse condition. And this means they can soon take over the space where you plant the crops. Therefore, weeds should be removed.    

However, the big question remains: should you fertilize or spray for the weeds first? In most, spraying should be done before fertilization, but it has an exception, too. Let us discuss this in detail. 

Why spray before fertilization?

Why spray before fertilization

Here are some of the reasons why we should proceed with weed control measures before fertilization:

Efficient nutrients delivery 

The weed hinders nutrient uptake to a large extent. When you fertilize a field that has weeds, the nutrients of your fertilizer get distributed to both your crops and weeds. As a result, the weeds survive, and the crops remain nutrient-deficient. When weeds are no longer there to compete for nutrients, the essential macronutrients are delivered to the crops efficiently. And this leads to a better quality of the produce. Therefore, it is important to eradicate these kinds of plants so that the crops can take up the nutrients.

Reducing stress on the lawn

Different kinds of weeds harbor pests that may give rise to many diseases. During the times your lawn is dealing with pests, fertilization can be stressful for them. Because of weed and pest removal, your lawn gets ready to absorb the macronutrients effectively. Hence, in such cases, weed control must be done before giving your lawn a dose of fertilizers.  

Minimizing fertilizer wastage 

A study found that weeds deprive the corps of N, P, and K in 47%, 42%, and 50%, respectively. Consequently, this increases the need for more fertilizer applications. But when there are fewer or no weeds present in the field, the nutrients are consumed only by the crops, reducing the need for frequent application.

When to use fertilizers before weed spray before a fertilizer?

It is important to understand that weeds grow when there is space for them to thrive. For instance, in a lawn where there is less competition (crops or plants), weeds are more likely to make their way through. 

Fertilizers provide the essential nutrients to the crops and ensure there is thick and heavy grass in the lawn, which may slow down weed growth. In such cases, fertilization before weed control would be a good decision. In short, fertilizers do not attack weeds but create an environment where they may not occur.

Parting thoughts 

Summing it up, it’s crucial to go for a weed-suppressing session before fertilizing as it can result in a good nutrient balance and better quality crops. It is suggested to wait for at least a week after you spray for weed removal, as it makes the soil ready for fertilization. But in case the weed growth is minimal, equipping the crops with an adequate amount of macronutrients before wee suppression may prove beneficial.
