Herbicides such as Winter Grass Killer is not absorbed by the leaf of the weeds like most other herbicides. This herbicide will need to be watered into the soil after application in order for it to be absorbed by the roots of the Winter Grass.

Herbicide Safety

No need to say it but, herbicides are highly poisonous.

Be sure to store herbicides in a safe place out of reach of children. Always be sure to keep children and pets off the lawn for several days after application. Even better would be to wait until after the first lawn watering before allowing pets and children back onto the lawn.

When To Water Lawn After Fertilizer Application

Generally speaking, you shouldnt water your lawn after applying weed and feed, because the water can disperse the substance disproportionally. Rain and watering may cause that you have a lot of weed and feed granules on one spot and not enough on the other, and like that, you wont have good results. Thus, check the weather forecast to be sure that after fertilization, it wont rain for at least 48 hours after youve used lawn weed and feed.

You will only kill weeds when they are actively growing. This means commencing sometime in May and finishing sometime in late September or early October.

I would not rush to apply lawn weed killer to the whole lawn in the early spring as there will be a lot of weeds that wont surface until later on. In early spring just spot or hand weed. For a good weed kill over a broad range of weeds in your lawn try starting in May. If you need to repeat the treatment you still have plenty of time before cold weather makes it impractical. Read the label of your weed killer to make sure repeat treatments are allowed.

A well fertilised lawn will help you get the most from your weed killer. In spring apply fertiliser in April and weed kill end of May or early June. In autumn feed 7-10 days before weed spraying.

One of my favourite times for complete lawn weed control is in late August or September whilst there is still some warmth around. I would recommend this if you just need the one application in the year. The reason for this is:

  • Most weed types are still around
  • The spring seeds in your lawn will have germinated so you get those as well
  • Killing weeds in autumn is easier than killing winter hardened weeds in spring
  • Youll have a weed free lawn until the next round of weed seeds germinate the following spring

What Time Is Best Time For Using Weed Killers

Spring is the best time for using weed killers. It would be better to use weed killer before a few weeks of cultivating the trees in your lawns. To destroy weeds entirely, you need a second treatment in between 2-3 weeks. In this case, the rest of the weeds deep into the soil will be destroyed completely.

At the time of weed control on your lawn, you must have to prevent the spread of seeds and destroy all young weeds before flowering. If you apply these tips, weed seeds will be decreased drastically.

According to the upper described process, you will be capable of doing a manual removal of weeds. But the weeds whose height has reached 6 inches or more will be less affected by herbicides. In this case, it is a crying need to mow all of the overgrown weeds, then wait and give them to grow to 2.6 3.0 inches. Finally, apply weed killer on them.

Everyone should be conscious of some factors before applying a weed killer. Those are:

  • Dosing accuracy
  • Processing of actively overgrown weeds
  • Proper temperature
  • Identify accurate weed before using any selective weed killer.
