What are Weed and Feed?

Weed and feed is a gardening product that contains weed chemicals and fertilizers in the same pack. It’s basically a two-in-one product to control weed and fertilize plants at the same time.

Many gardening product manufacturers sell these products under Weed and Feed marketing name, among those the most prominent one is the Scotts Turf Builder Weed & Feed.

Scotts is an American company that manufactures a wide variety of gardening products, and a majority of people have a positive experience with Turf Builder.

The manufacturer claims it to have 2 times more potent than its earlier formula to control dandelion and clover weeds while improving the absorption of its fertilizing nutrients.

In these products, the weed formula contains herbicides agents such as Dicamba or MCPP, which are found to be effective in killing common plants such as dandelion and other green leafy weeds. Some countries such as Canada, no longer allow combining weed and feed but it’s allowed in the US. 

The feed contains three primary plant nutrients such as nitrogen, phosphorus, and potassium. Plants need these essential nutrients for healthier growth.

Below is the role of fertilizers in the growth of the plant. 

  • Nitrogen – Basic nutrient for the plant which promotes the growth and helps enhance the color of flowers and leaves.
  • Phosphorous – It helps grow the stronger and healthy root of the plant. Healthy roots provide better support for the plant and help pass the nutrients from the ground to all parts of the plant.
  • Potassium – It enhances the overall health of the plant, which allows it to fight disease, insects, and safeguard it from harsh weather such as drought or cold.

The fertilizer is indicated by its ratios, for example, 10-10-10, which is a typical all-purpose fertilizer. It means the fertilizers have 10 percent nitrogen, 10 percent phosphorus, and 10 percent potassium.

When to Apply Weed and Feed

The best time to apply is at the start of the gardening season, which is by the end of March or the start of April.

This is the time when the weather starts getting warmer and moisture in the atmosphere is high. The weeds are quick to grow before other plants. The application of weeds and feeds during this time suppresses weed growth while providing essential nutrients for your plants.

Keeping weed in check from the beginning also helps you later as you don’t have to spend too much time pruning or taking out plants from your garden. 

5 Things To Know Before Applying Weed And Feed

The weed and feed are gaining popularity because of their convenience. You basically cut down your gardening effort in half, at least for controlling weeds and fertilizing plants.

But consider these following factors beforehand to make sure that you get a benefit when using weed and feed and there won’t be any adverse effect to your garden. 

1. Know Your Garden Weeds

It’s a good idea to know about the most common weed problem you encounter on your lawn. Depending on the area you live in, you may have some more pervasive type of weed variety than others.

There is no point buying a weed and feed which is specially targeted for the dandelions whereas in your lawn you have more crabgrass or chickweeds. Knowing the weed types in your garden will help you choose the right product, which will give you the best result. 

2. Type Of Grass

You should know the type of grass on your lawn. These products are specially rated for a particular kind of grass. Using the wrong product type may damage your whole yard.

Moreover, you also want to make sure that feed fertilizer is suitable for the grass and plants in your garden

3. Read the Label

Know the ingredients inside the product before you purchase the product and follow the application direction. The wrong application or too much use may harm the plants.

Most of these products contain a weed-killing substance called Atrazine. It’s instrumental in killing weeds and other plants, including trees. Too much application of it around the new plants may damage the plant roots, so apply it at a bit safer distance and use the correct recommended amount. 

4. Choose the Right Timing

Like anything else, the timing is essential when applying weed and feed products. If you have mature plants and trees, then spring is the time when plants start the new growth of leaves and branches. 

Plants are very vulnerable at this time since they are in high growth mode and quickly absorb water and nutrients, including other chemicals from the ground. You can use it during this time but keep it away from the plants or trees which you don’t want to damage.

You can be more relaxed in applying it during the summer season as it does not adversely affect much during that season. In the summer season, the hot weather slows down the plant’s growth and nutrient absorption process. 

5. Lawn Seeding

Don’t use weed and feed when seeding your garden. It may seem counter-intuitive, but if you are planning to sow your yard, then don’t sow and use weeds and feed together. 

This is because it’ll undoubtedly kill the weeds, but it’ll also damage the fragile grass shoots. Use it once the grass patch has grown up a bit and got a good hold on your garden. 

How To Apply Weed And Feed

You can buy it in either granular or liquid form. Depending on the type, the application process may differ. Many people prefer to use a liquid form as it’s easier to apply by simply mixing it with water and spraying it in the garden.

If you are using a granular form, then you should use a spreader. You can spread it manually, but it’s difficult to propagate in the right proportion. This results in an uneven distribution of products and may result in patchy growth in the garden.

For Atrazine based weed and feeds which are used for St.Augustine grass or centipede grass, you should water the plant after application. This helps Atrazine wash from the leaves and get into the soil from where it works more effectively.

For Trimec based weed and feeds, apply sometime after watering the lawn as the herbicide has to stick to the plant leaves to work correctly. 

Are Weed And Feed Safe For Kids And Pets?

When you use it on your lawn, it’s advisable to keep pets and children away from the yard for a few days. The chemical compounds in the weed and feed, if ingested, can make them sick.

The small amount of ingestion may cause dizziness and upset stomach, whereas a significant amount of intake may be fatal. 

Alternatives To Weed And Feed

It may not be ideal to use it if you have a large infestation of weeds in your garden. In that case, it’ll be better to use a dedicated Concentrate Weedkiller. You may get better weed control results within 2 to 4 days.

Similarly, you may want to use standalone organic fertilizer if you don’t have a weed problem or you have plants that have special needs. The weed and feed compounds are suitable for regular maintenance of the garden. It’s not advisable to use weed and feed for the newly seeded lawn as it may damage it.
