    Hand weeding is still the best defense on small lawns where the number of weeds isn’t overwhelming. It’s most effective against annual broadleaf weeds. Pulling them while they’re young before they flower and seed is the simplest way to control and prevent them from spreading.

    If you decide to use an herbicide to control weed in your lawn, be sure to select the appropriate product for your situation. There are hundreds of different herbicides on the market. You can either use pre-emergence herbicides during off weed seasons to prevent the growth of weed or post-emergence herbicides when they’ve already sprouted.

    Water deeply

    Water your lawn about once a week, and give it about an inch of water. This will help the roots of your grass grow deep into the soil, preventing weeds from taking root.

    How to prevent weed from growing

    The best way to prevent weeds is by keeping your lawn healthy.  Often times, weeds are a sign that your lawn doesn’t have enough nutrients or has poor soil. To keep your lawn healthy, you should water your lawn regularly, fertilize your lawn several times a year, and treat any lawn diseases as soon as possible. Other ways of preventing weed include;


      • Apply a pre-emergence herbicide
      • Cover part of your lawn that don’t have grass (mulching)
      • Grow taller grasses
      • Plant closely to prevent weed
      • Mow with a mower

      Apply a pre-emergence herbicide

      A pre-emergent herbicide is a weed killer you use before you see weeds.  By treating your lawn in the spring, you can kill weeds before they appear. Pre-emergence herbicides include;

      • Prodiamine (Barricade equivalent) is the longest-lasting, and most economical due to lowest application rates.
      • Isoxaben (Gallery equivalent) prevents a very large list of Broadleaf Weeds.
      • Oxadiazon (Ronstar equivalent) is a great granular option – safe in all turf and ornamentals.

      Cover those parts without grass

      If you have parts of your lawn that don’t have grass, cover it with mulch or landscape fabric.  A thick layer of mulch will keep weeds from growing.  Landscape fabric can be used when you are planting flowers or vegetables.  It allows water to get in the soil, but keeps weeds from growing.  By cutting a hole for the plants you want to grow, you can keep weeds from growing in unwanted places.

      Grow tall grasses

      Set your lawnmower to a higher setting.  Weeds need sun to grow and tall grass will shade your lawn.

      How and the best time to apply herbicides 

      You 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 won’t surface until later on. Apply your weed killer (herbicides) under the following conditions.

      • Ensure you have fertilized the lawn beforehand to maximize the effect of the weed killer.
      • When moisture is available in the soil. You can harm the grass in drought conditions.
      • When it is unlikely to rain for at least 6 hours.
      • On dry grass. Wet grass will dilute your weed killer.
      • In calm weather – wind will blow spray even from a watering can sprinkle bar.
      • Avoid frost or freezing conditions which may occur in spring.
      • Avoid strong sunshine.
      • In summer it is best to apply weed killer in the cooler evenings.
      • Any time after fertilizing. Let the feed kick in (one to two weeks) then treat the weeds to get a better weed kill.
      • After mowing. Leave at least 2 days if applying liquid lawn weed killer to the whole lawn. Don’t mow for a further 3 days.
      • When mowing prior to weed treatment don’t mow close. If you mow close and chop the leaves off the weeds there is nothing left to spray.




      Disadvantages of weed in lawns

      When weeds invade your turf, they compete with healthy, desirable grasses for air, water, and nutrients. When fertilizer is applied, for example, weeds are often quickest to soak up the nutrients that would otherwise fuel your lawn’s growth. This results in the weakening of grass plants, making your lawn more prone to other issues, such as disease, insect infestation, and drought. Weeds also compete for space – spreading quickly and ultimately taking over what was once your green oasis.
