How does this compare to roundup and how long until you see results as it doesn't seem to be killing the weeds I sprayed its been 4 days I also used weed & feed on lawn and that seems to of started working already after 4 days when it says may not see results until upto 3 week ?

It has the SAME active ingredient as round up. There is no comparison except that round up is (RTU) ready to use.
Hortico weed killer 360 has to be mixed with water. 4 days is way to early to see any results. Give it up to 2 to 4 weeks, just be patient. The weather plays a big part in how long it takes. In cold weather, longer. In sunny weather, shorter. If it rained within 6 hours of applying you may have to reapply.
Weed and feed has different active ingredients, same thing has happened to me. Hope this helps you out.

Does it kill clover

1 answer
gingmo
gingmo

Yes it does, but don't use it if the clover is growing on your lawn or else your lawn will die off as well.
If it is not growing on your lawn use 10 ml per 1 litre of water.
If it is growing on your lawn you have to use a selective weed spray such as Yates bindii and clover killer
from Bunnings and mix 15ml per 1 litre of water. Just follow the instructions.
The Hortico weed killer is not selective, it will kill whatever you spray. Hope this helps you out.

I have all sorts of weeds in my buffalo lawn due to me being ill for the last couple of months of winter and not giving my lawn any care. Would Hortico weed killer be suitable if I just mix it in a watering can and cover the lawn and weeds. Regards

No, Big Al, Hortico weed killer is for getting rid of weeds around pathways, edges, and so on. So just pouring Hortico weed killer on your lawn will just kill everything - the weeds, the lawn; everything.

If you want to kill just the weeds and leave the lawn fairly much intact, get a "weed 'n' feed" type product and apply that instead.

can i mix 1L hortico weed killer 360 in 5L water so I do not have to return to respray?

I have never had a problem with efficacy of Hortico 360 at the recommended levels. And I certainly don't have to go back and respray.

Maybe you are spraying too soon before rain? Or are there other weeds popping up around the dying ones?

Using the entire litre in one go is just pointless really - it will achieve no better a result.

gingmo
gingmo

Use it at the recommended application rates. Generally mix 10mm of Hortico 360 per 1 litre of water.
Read the application rates for what you are trying to control/kill. Some weeds and grass can take up to 1 month
to die off. Don't spray if rain is forecast within 6 hrs of application or you will definitely have to return to respray.
New weeds will always pop up depending on how big and how many bare patches you have. This is something we all have to monitor. You can only spray what you can see. If new weeds pop up you will have spray them. Do it once and do it properly an be patient. I'll repeat it for anyone else reading this. READ THE INSTRUCTIONS.

Instruction manual says effects show in 7 to 10 days.?? Did most users find the effects taking only after the specified days or earlier??

1 answer
gingmo

It depends on what type of grass or weed you are trying to control and It also depends on the temperature. It dies quicker in warm or hot weather. As soon as you notice some yellowing you know that its taking effect. Some people over spray and this can sometimes only burn the grass or weed making it look like its dead. Just be patient
and let the product do its work. I wouldn't spray in the heat of the day. Do it in the evening or at any time when the sun is not to hot. Don't over spray. I have found that
instruction manuals are only a guide. You'll learn from experience when something has died off. The yellowing is a sign that the weed killer is traveling to the root where
it will eventually die off. Good luck and hope I've helped in some way. P.S. Make sure that it is not going to rain within 6 hours after applying. If it does then you need to
reapply as the rain will have most likely washed the active ingredient off the weed/grass.

If i have 5 liters of water do i use 25mls of weed killer?

1 answer
gingmo
gingmo

Read the application instructions and it will tell you how many mls per litre you need to mix for what you are trying to control (kill)
Read the WEEDS CONTROLLED section then the rate of mls per litre. If you don't know the particular weed/s you want to get rid
type in common weeds on google images. Believe me you'll find it. Broad leaf weed application says 5 to 10 mls per litre. Hope this helps you out.
There is also an application rate for different types of grass.

Is this product harmful to pets?

As far as I understand you need to give it enough time to dry after application otherwise it could harm pets (and bees). I tend to spray only at dusk as most bees will be 'gone' and I will keep pets in for a few hours.

I would assume so. The product label only mentions to keep away from aquatic animals. I would rather be safer than sorry.

As has been often mentioned here, Hortico Weed Killer is a particular concentration of glyphosate.

A quick Google search to your question brought up this comprehensive answer, from the (English) Daily Telegraph of July 2016:

"Roundup (Glyphosate) is practically nontoxic to mammals, but the surfactants that are in the formulations are irritants, and can cause gastro-intestinal upset if eaten while wet. They might also cause skin irritation if the product contacts the skin while still wet. Once dry, it’s completely safe, so in most cases, it’s just a case of keeping pets away until the weeds have fully dried .

It’s sometimes said that wilting plants are more appealing to animals, and so might increase the palatability of poisonous plants, that’s more of an issue for herbivores (rabbits, guinea pigs, sheep, cattle, goats) who are likely to eat large quantities of plants. Dogs nibbling at a few leaves aren’t likely to have any problems unless the plants themselves are highly toxic (such as Lily of the Valley).
One extra tip: apart from fear of toxicity (which is actually minimal) , if a pet walks on areas that are wet with Roundup, they may then walk all over your lovely lawn, killing the grass in their footsteps (literally).."

Its a chemical spray so I guess its harmful to anything that lives.....as far as I know after spraying it needs to have enough time to dry properly before letting your chickens roam....betta check with the supplier I'wld say.

This is not a organic weed killer, so I would take caution. The instructions only mention that's its bad for aquatic animals.

Sorry, I am not qualified to answer that question. If it was my garden i would let the ground rest for while before planting any crop in the area I sprayed. Better check with an expert though. cheers Daniel

How much do I use per litre of water

10ml per liter unless it's a particular woody weed or a type of tree, than it's either 15 or 20ml. If you open up the back label, there is a table that tells you how much to use.

I don't believe so. I have used a home made non toxic weed killer previously the uses vinegar and salt. A quick Google should find it.

I would check with Bunnings or Hortico. I used it on the front lawn but my dogs do run on it occasionally. Plus I am not sure the product is that strong in the first place. Having said that, my gut feeling is to wait at least a day even if Hortico says it is safe to use around animals.
