Roundup is one of the most popular weeds spray you can get, and used by homes and farmers. The main ingredient is Glyphosate. Roundup is a non-selective herbicide that kills anything it touches; hence, be careful on your grass.

Weed Killer When to Spray?

Before you spray weed killers, there are things you need to know to get the best effect. This is the same with commercial or a homemade spray for weeds.

Also, you will see that herbicides are not as harmful to humans as pesticides.

The Difference Between Pre-Emergence and Post-Emergence Herbicides

Pre-Emergence Herbicides

Use these on established lawns in an attempt to disrupt the life cycle of the (summer) weeds. Benefin and Dithiopyr are the main compounds.

You use these before weeds can germinate, such as early spring, and follow this up with a second does 8-weeks after the first spraying.

Post-Emergence Herbicides

Glyphosate is used and becomes absorbed by the plant tissues. You find this weed control works best to kill weeds, which are still young.

Guide on Application of Weed killers

Seasonal Application of Weed killers

  • Spring – Spring is the best season when to apply weed killer as it is warm, and there is a chance to use your pre-emergent where you can stop weed seeds germinating.
  • Summer – Spraying here has to be at the tail end of the summer. By doing this, you can minimize the problem come the following spring. Use herbicides that kill pest grasses and apply in the late morning or early afternoon to stop evaporation.
  • Fall – Weeds are most vulnerable at this time of year, and they won’t survive the winter. October is the best month, and you apply two treatments separated by two weeks.
  • Winter – You can apply in the winter if the temperature rises, although they can lose their impact in freezing conditions.

Roundup When to Spray

It’s not just Roundup, which needs consideration when spraying weed killer. Most weed killers will need applications at certain times of the day. One thing often an oversight is how local climate affects the best time to spray weeds.

Warm Climates

When you look to spray your weeds, this will be either any time later in the morning or afternoon.

The temperatures won’t rise above the mid-’80s, and the temperatures at night will be around 60 to low 70’s.

Cold Climates

If you live in these sorts of climate, it isn’t the right time to spray if there is dew on the grass and weeds because it will weaken the solution. Nighttime cold weakens the impact, so you can only spray weeds if there is no snow or frost around mid-day when the sun is highest.

Temperate Climates

In these areas, your plants are least active from early evening until the following morning. It is here where the best times are toward the late morning or the early afternoons, and avoiding the hottest parts of the day. (Find the Best Liquid Fertilizer for Grass)

Is Weed Killer Safe

One thing not mentioned here is if you suffer from broadleaf weeds such as dandelions in your lawn.

In these instances, you may need a granular weed killer to spread on your lawn. Just be sure not to use Glyphosate-based and keep it away from your plants.

  • Using a broadleaf killer, you can use these following steps rather than spraying weeds in your lawn.
  • Apply to grass in the morning when there is dew on your grass
  • Make sure there is no rain predicted for the next 24-hours
  • Apply when the weeds are in active growth
  • Apply granular weed and feed weed killer lawn treatment when the wind is calm as it stops it blowing on your plants
  • Apply when the temperatures are above 70 degrees Fahrenheit

Here you have all the options of spraying for weeds or using the granulated option. Spray weed killers can be the easiest solution, yet they may not offer the best results for grass.

Your lawn will be very different from other areas of your yard. Your lawn will require a treatment that will kill weeds, yet it won’t harm your lawn or nearby plants.
