How to Use Yates Weed and Feed (Granular & Spray)

Yates Weed and Feed is a combination herbicide and fertiliser in one. It’s designed to make weeding and fertilising your lawn quick and easy. 

Yates Weed and Feed is a great product to use on your lawn. It’s designed to kill common weeds such as clover and bindii and will feed your grass at the same time.

Weed and Feed comes in two different forms, granular and liquid.

What is Granular Weed and Feed?

The granular product can just be broadcast over your lawn and is safe to use on all grasses including couch, ryegrass, bent, kikuyu, buffalo, and Queensland Blue.

It controls most broadleaf weeds such as clover, bindii, thistles, and dandelions.

At the same time, it provides your lawn with the essential nutrients that it needs to grow lush and green.

Here’s a breakdown of the essential nutrients in the granular form:

  • Nitrogen 5%
  • Iron 5%
  • Sulfate 8.5%

What is Liquid Weed and Feed?

The liquid Weed and Feed comes in a handy hose-on bottle. All you have to do is attach your hose and water your lawn with the product.

This formula is safe to use on most grasses including couch, kikuyu, and Queensland Blue. 

However, it should not be used on buffalo grass. If you want to use a liquid Weed and Feed on your buffalo lawn, there’s a special formulation called Yates BuffaloPro Weed and Feed that does not contain Dicamba and is safe to use on your buffalo grass.

It will effectively control weeds such as clover, bindii, capeweed, cudweed, docks, dandelions, thistles, and wireweed.

Once again, it will provide your lawn with essential nutrients at the same time.

Here’s a breakdown of the major nutrients provided by the liquid Weed and Feed:

  • Nitrogen 11.5%
  • Iron 0.13%

What does Weed and Feed do?

Weed and Feed contains a number of plant hormones to kill broadleaf weeds (MCPA and Dicamba).

These hormones are absorbed by the weed leaves and then transported down to the roots. This forces the weeds into disordered growth and leads to eventual death.

How long does Weed and Feed take to work? Normally, it takes around 4 weeks for the weeds to eventually die completely.

In addition, the iron contained in the granular form has a burning effect on any broadleaf weeds but does not harm the grass.

At the same time, the nitrogen and iron contained in Weed and Feed give your lawn a nutritional boost.

Lawns need plenty of nitrogen and iron to grow strongly and remain nice and green. 

When to use Weed and Feed

The best time to use Weed and Feed on your lawn is in early spring. This gives your grass a good nutritional boost as it springs into new growth.

However, it may not effectively control the weeds that haven’t actively started growing yet.

For this reason, you can apply the product again after around 6 weeks. This ensures that you’re not overfeeding your lawn which may result in a build-up of salts in the soil.

How to use weed and feed spray (hose on)

When using any type of product in your garden, it’s important to read the instructions on the label first.

Here’s how to apply liquid Weed and Feed over your lawn.

  • Attach your hose to the connector on the top of the bottle.
  • Turn the On/Off switch to On and spray evenly over your lawn in a sweeping motion.
  • 2 litres should cover an area of around 130 square metres. 

Alternatively, you can also use the product by diluting it with water in a watering can.

This is ideal if you only have a small area to cover or there are flower beds adjacent to your lawn.

For this, you want to dilute 300mls of the product in 9 litres of water to cover 20 square metres.

Important precautions:

  • Do not use on buffalo grass unless you are using the specially formulated version.
  • Avoid mowing your lawn for 7 days both before and after the application.
  • Don’t use on lawns that are under stress.
  • Be careful to avoid the spray drifting onto other plants in your garden.
  • Grass clippings of a treated lawn should not be used as mulch or fed to poultry or livestock.

How to use Yates Weed and Feed granular

The granular form of Yates Weed and Feed is easy to apply. 

Broadcast the product over your lawn either by hand or by using a broadcast fertiliser spreader. 1 kg should cover around 15 square metres.

You’ll want to avoid watering your lawn for 2 days and then repeat the application after 6 weeks.

Important Precautions:

  • This product can stain your hard surfaces so avoid any spillover or sweep off immediately.
  • Avoid using the product on your lawn during very windy or hot weather.
  • Don’t apply to lawns that are stressed.
  • Keep pets and children off the lawn until the granules have worked their way down into the soil or until the product has been watered in.

Weed and Feed granules vs liquid: which to choose?

There are a number of things to consider when it comes to choosing either liquid or granular Weed and Feed. 

If you have a buffalo lawn, it’s safer to use the granular form unless you opt for the specifically formulated Pro liquid one.

Also, Granular Weed and Feed is also more useful in treating pre-emergent weeds that haven’t started fully growing yet. That’s because it will kill the weed seeds before they germinate.

Finally, liquid Weed and Feed is the preferred option if you want fast results on weeds that are actively growing.

    • Hi Michael

      Personally, I would not use anything on a brand new lawn that was only seeded 8 weeks ago. The grass is still young and tender and needs time to become established.
