How long after a lawn treatment can I water?

 

Everyone looks forward to seeing the results of a recent lawn treatment. Each lawn care treatment is one step closer to a beautiful lawn or maintaining a healthy green lawn.

 

These treatments often take time to take effect. Homeowners are often interested in knowing what they can do to ensure the best results from their recent application.

 

These products frequently limit the amount that one can apply in a year. Others restrict use to certain times of the year. For this reason, if a product gets washed off, it might not be able to be reapplied. If this happens a different more expensive herbicide may be needed to provide weed control.

 

Therefore, it is important to use these lawn weed control products in a way that they can achieve their desired effect. Each herbicide on the market comes with a label that describes how the product can legally be used.

 

These instructions are considered law and should be obeyed. If a lawn service provider used the product, they can give instructions about the specific products they used. Here are some general considerations about watering after lawn treatments.

 

When to water after pre emergent?

 

Considering all the products used in that treatment helps determine when to water a lawn treatment. Lawn treatments often involve multiple products.

 

You should consider the watering needs of each product. If a post-emergent was applied with the pre-emergent, the post emergent herbicide could have different needs than the pre emergent. This is frequently done.

 

In this instance, the needs of all the herbicides should be individually considered. At least two treatments each year will include pre emergent herbicide. This lawn weed treatment prevents weed seeds from germinating.

 

Lawn treatment companies typically apply a pre emergent in the late winter or early spring. Then they apply a pre emergent herbicide in the late summer or early fall. The goal is that these weed preventers will prevent weeds from growing.

 

To ensure the effectiveness of these pre emergents, you must water them in within a certain time after application. This is called watering in the pre emergent.

 

How long you have to do this varies from one pre emergent to another. Some need to be watered in within a couple of days.

 

Others can go as long as two weeks. It is important to know this information to ensure the pre emergent is effective. If you do not water the product, the elements can break it down, reducing its effectiveness.

 

How much water it takes to water in the pre emergent also varies. Most of the time it is around a 1/2 inch of overhead irrigation. Sprinklers or rainfall can provide this. This is true of both liquid pre emergents and granular pre emergents.

 

When to water after post emergent?

 

To achieve effective weed control for lawn post emergents much have enough time to absorb into the weed. A common term on herbicide labels is the rain-fast period.

 

The herbicide needs this amount of time after the lawn application before rain can fall on it. Rain or early irrigation could wash away the weed killer. This can happen before the weed can absorb the herbicide. You can check the herbicide label or ask the lawn treatment service for info about the lawn application.

 

Different post emergents are used to treat different kinds of weeds. In general, this can be between a couple of hours to a couple of days depending on the selective herbicide that was used.

 

When to water after fertilizing?

 

You can water the lawn immediately after spreading lawn fertilizer. Doing so helps to wash the fertilizer off the grass reducing the risk of fertilizer burn. It also helps to prevent fertilizer burn by ensuring the turf has enough water.

 
Fertilizers naturally contain salts. These salts can cause the turf to struggle to absorb needed water. This is why it is essential to ensure your lawn has adequate water before and after fertilizer application.
 
It is important to remember however that during fertilizer applications post emergents are often sprayed. Lawn treatment companies often spot spray weeds while they are on site applying fertilizer. There fore if hiring a lawn treatment company they should be consulted for direction from the label regarding the products they used.
 

The takeaway.

 

These are some general guidelines about when to water after a lawn treatment. If you have applied the products yourself be sure to consult the labels on the products you used.

 

Consult the label for each herbicide. They often have different rules regarding irrigation after application.

 

The manufacturer of the herbicide will let you know the best and legal way to use their products. If you hired a lawn care service to do this for you, they should provide you with any needed directions.
