Q) Can you provide me with any advice with regards to the use of a total weed killer such as glyphosate around plants I wish to keep?
A) Weed killer such as glyphosate will only kill a plant if the spray lands onto the greenery of that plant as this is the only way it can be absorbed. The weed killer cannot be taken up through the roots of the plant. If glyphosate, or any total weed killer, is being used between wanted plants then care should be taken not to get the spray onto those plants. A good tip is to hold a large piece of cardboard in front of those wanted plants so they are protected from any potential spray drift.
Q) I bought some glyphosate concentrate and am about to use it. Can you explain why there are two different application rates stated on the label depending on whether a sprayer or watering can is used?
A) The only difference between the two different application rates stated on the label are the volumes of water used. You will note that the same amount of product is applied to the same area of ground in both instances. A larger amount of water is required to apply the weed killer through the watering can to ensure even and easy coverage of the designated area. A smaller volume of water is required to apply the weed killer through the sprayer to the designated area as a sprayer provides a better surface area coverage as finer droplets are created through the sprayer nozzle. If the same quantity of water suggested for the watering can were to be applied through a sprayer it would take a long time to spray out.
Q) I have just moved into a new property and I have lots of weeds to deal with in the back garden. I have been told that glyphosate is the best weed killer to use for such but can you tell me when is the best time to use it?
A) Glyphosate based weed killers contain the active ingredient glyphosate which is systemic in action. This means that it is absorbed through the leaves of the weed and then it travels within the weed to all parts including the roots. Once it has fully circulated within the weed, it then causes death. This process takes time. Weed death should be seen approximately 3 weeks after application of the glyphosate weedkiller. As this weed killer is systemic, it is important that it is applied to weeds which are actively growing. Avoid using the weed killer in times of drought or when temperatures are low as the weeds will not be growing efficiently. It may seem a strange concept but it may be useful to water any areas of weeds a day or so before the application of glyphosate weed killer to get them growing! The golden rule when using glyphosate weed killer is The better the weeds are growing, the better the product will work!
Q) I treated some weeds around my garden last week. They seem to be showing no signs of death, whilst other weed killers I have tried in the past, such as Kills Weeds Dead Fast!, turned the weeds brown and crispy within days of treatment. Why has glyphosate not done the same?
A) Glyphosate weed killers contain the active ingredient glyphosate which is systemic in action. This means that it is absorbed through the leaves of the weed and then it travels within the weed to all parts including the roots. Once it has fully circulated within the weed, it then causes death. This process takes time. Weed death should be seen approximately 3 weeks after application of the glyphosate. The other weed killers you have tried which show much faster control are known as contact weed killers. These quickly affect the upper parts of the weed which come into contact with the weed killer. However these type of weed killers are not nearly as effective as glyphosate at completely killing the weeds. In many instances weeds treated with a contact weed killer will regrow as the root has not been killed. Glyphosate will kill weeds completely.
Q) Im clearing an area of weeds so I can seed a lawn. How long do I need to wait between applying glyphosate and laying the grass seed?
A) Glyphosate is deactivated on contact with soil. It only works by absorption through the green part of plants. Grass seed could be applied straight after the application of the weed killer but realistically it is better to wait until the weeds are dead as it may be necessary to retreat some of the more persistent weeds and it is much better to wait and clear the weeds fully than have to try and deal with them as the new grass is growing.
Q) How can I stop weeds taking over the lawn?
A) There are lots of things you can do to help prevent weeds from running riot, correct mowing, feeding the grass to increase its vigour (and to help it crowd out the weeds), and regular treatment with a selective weed killer will all help halt the invasion. Also Lawn Scarifying, Aeration, Hollow Tyne Coring.
Q) How do I remove really persistent weeds from my lawn?
A) Persistent weeds must be removed before they take over completely, or build up a large bank of seeds in the soil for future years. Regular hand weeding or can help, but relatively large areas need to be sprayed using a concentrated lawn weed killer, such as Verdone. selective lawn weed killer Using a Feed, Weed and Moss killer regularly during the growing season from April to September will also help improve grass vigour and reduce weed and moss growth.
Q) When is the best time to apply this product to kill lawn weeds?
A) Lawns weeds are best controlled when they are actively growing and this is normally in spring when the soil is moist and conditions are warm. Always leave the lawn a few days after the last mowing to allow the weeds time to grow a little before applying the product and do not cut for at least 3 days after application to give the weeds time to absorb the weed killers. Early morning on a dry day in April or May is usually when the best results are achieved make sure you choose a selective weed killer for lawn applications as its a selective weed killer it will only kill the weeds and not your lawns.
Q) I have used the lawn weed killer product two weeks ago but my lawns weeds look better than ever, why arent they dying?
A) The chances are the selective weed killers are working well if your lawn weeds seems to be growing faster. These weed killers are systemic and are absorbed into the weed and must travel to all parts of the plant to work well. It can take up to 4 weeks for the weed to die. The effectiveness of all lawn care products is dependent on the weather and this is why they are best applied when the weeds are growing actively. To work effectively, they should not be applied when rain is imminent, when the soil is dry or conditions are too cold for the weeds to grow properly.
