4. Weed Killer
Many gardeners prefer not to turn to using pesticides or weed killer to get rid of weeds as they are concerned about the damage it can do to the lawn. However, weed killers are designed to specifically target weeds and when used correctly should do no damage to the lawn.
Be aware that weed killer is only effective to eliminate weeds in the growing phase. Applying it in the fall months when winter weeds are germinating and just beginning to grow is, therefore, the ideal time to use weed killer.
It is preferable to apply the weed killer when the soil is moist. This will help prevent damage to the lawn. If the soil is dry and there has been no rain for a few days, it is recommended to water the lawn before applying the weed killer.
However, while the soil should be moist, the grass should preferably be dry. Water droplets on the grass will dilute the weed killer and make it far less effective. It is also best not to apply the weed killer if it is likely to rain in the next 6 hours to prevent dilution.
Strong, direct sunlight should also be avoided for the recommended duration of application. Hot sun will dry the weed killer out before it can be effective. It is therefore best to apply in the early morning or late afternoon.
Weed killer should not be applied directly after mowing and it is advisable to wait 2 or 3 days. This will help protect the lawn as well as ensure that leaves are available on the weeds for the treatment to work. It is also recommended to wait at least 3 days after using weed killer before mowing again.
It is important to keep in mind that weed killer is toxic (poisonous) and that it should always and only be used according to the manufacturer’s instructions.
