There is no universal time to spray the weed killers. Instead, there are pointers or yardsticks that point to the correct time to do so. These are:

  • Plant Species

Different species of plants require spraying at different times. Those that are planted for their leaves may not be sprayed when the harvesting is around the corner. That may imperil the safety of the harvests overall.

  • Stage of Growth and Development

Closely related to the above is the stage of the growth and development of the plant. Most plants are sprayed during their growing seasons. These are the times just after the planting but before maturity; not early or later.

  • Temperature

It is generally wrong to spray the harsh chemicals when the temperatures are too high or in the event of a drought. The weed killers themselves contain chemicals that may desiccate the plants or even destroy the fruits thereof.

  • Time of Day

On the whole, the plants are better sprayed early in the morning. This is to give the chemicals sufficient time to trickle and set a firm base on the leaves. The early morning also slows down the evaporation of the chemicals upon applications.

  • Level of Precipitation

As a last consideration, the plants should be sprayed at a time when there is not going to be any form of precipitation within a duration of 24 hours. The logic is simple; the chemical components of the weed killers need time to trickle and not to be washed away.


Just like the timing, there is no universal frequency with which you should spray the weed killers. Instead, the following factors determine that metric:

  • The severity of the Pests

How severe are the pests or the likely damages they may portend? Too severe damages or infestations require more frequent spraying and vice versa. That is for the sheer reason to reverse the trend a bit too fast.

  • Strength of the Plants

The strength of the plants also matters considerably. Stronger plants like the perennial ones are able to withstand more frequent delivery of the chemicals than their weaker counterparts. You do not want to imperil the growth of the plants, do you?

  • Stage of Growth and Development

Plants are generally able to bear the chemicals in the middle and later stages of development than their earlier ones. If you must spray them earlier, you have to moderate the sprays to preserve the strengths and overall health of the plants.

  • Desired Outcomes

What kinds of outcomes are you looking at? Do you just want to preserve your crops from further infestation (preventive) or kill the existing pests (curative)? The former requires more limited spates of spraying than the latter.

  • Manufacturer’s Recommendations

Each manufacturer has its own laid down regulations and instructions of use. You have to see to it hence that you read the recommendations keenly before setting out for your use and engagement thereof.


Follow the steps below to use the weed killers:

Step I: Put on the necessary protective gears

Start by putting on the necessary protective gear. The apron or overall is to shield your clothes from the direct contact with the chemicals; a pair of gloves is to protect your hands from direct exposure to the chemicals; a face mask will guard against possibly inhaling the harmful gases; while a pair of gumboots help you walk freely.

Step II: Load the sprayer with the weed killers

Now load the sprayer with the weed killers. Simply open the container and drain the contents into the sprayer. Take great care though that you do not spill the contents on the floor or other areas. That can only happen if you are slow and meticulous.

Step III: Direct the nozzle to the portions of the plants you target

Get to the core of the spraying itself now. To do this, direct the nozzle to the precise portions of the plant you target or have in mind. Go slow and steady to prevent any unnecessary harms as you go about this. Be mindful of those areas that are too demanding.

Step IV: Trigger the nozzle to release the contents

Trigger the nozzle of the sprayer to release the contents of the sprayer and its contents. The severity of the trigger is to depend directly on the severity of the infestation of the plant as well as the outcomes you so desire.

Step V: Make as many passes as can be

Make as many passes as can possibly be. This is to ensure that the pests are completely eradicated and that the plant is left wholly clean and unaffected anymore. The number of passes may depend directly on the kind of plant you target as well.


There you have them! You now know what to do to reverse the infestations of the weeds in your garden, don’t you? Go ahead now and do just that! We wish you all the best in your attempts thereafter. Is it too much to ask you to now pass this information on to the others that equally need it?
