A Guide to Weeds and Weed Killers


One of the most important things I learned about weeds and weed control is this: weed killers should not be your first resort. Weed killers, or herbicides, are ultimately toxins and applying them on the first sign of trouble can be risky for the living things in your yard or garden that you want to protect.

Additionally, I learned that weeds are a symptom of an unhealthy or ill-maintained lawn. It may be improperly fertilized, irregularly mowed, uncultivated, or poorly watered. Therefore, you can prevent most weed invasions with the adequate lawn maintenance as well as excellent weed prevention practices. First of all, let’s take a look at the different types of weeds.

Types of Weeds

There are three main types of weeds and if you’re to treat an invasion in your yard properly, you’ll first have to determine the kind of weed that’s taking over. This inspection is even more important when you’ll have to buy a chemical weed killer.

1. Broadleaf weeds

Broadleaf or broad-leaved weeds are, as the name implies, the type that has leaves, whereas grassy and sedge weeds resemble grass with their blade-like foliage.

Some common broadleaf weeds are dandelions, white clover, and creeping Charlie.

Among the weeds, broadleaf are typically the most dreaded since they are hardy, steal a lot of nutrients from your plants and can quickly take over your lawn if you leave them unchecked,

2. Grassy Weeds

Grassy weeds or grasses more closely resemble grass with their narrow leaves, delicate flowers, and rounded or flattened stems.

Typical examples of grassy weeds are crabgrass, goose grass, and also foxtails.

3. Sedge Weeds

Otherweeds that resembles turf, albeit in tall, thin clusters areSedges. There are most often in the form of nutsedge, especially yellow nutsedge, as well as bulrushes.

Prevention Better than Cure

If weeds have yet to invade your lawn fully, then you might still have time for some preventive measures. The most important thing to remember is that t fight unwanted weeds; you must promote an environment that is ideal for the plants and vegetation that you want. Here are some tips:

Preventive tips

· Proper watering

Ensure that your plants and your lawn are not over-watered or under-watered. You ought to take a look at some great sprinklers here.

· Regular Feeding

Ensure that you apply the right fertilizer, in the right amounts, and at the right times.

· Improve your mowing practices

Several mowing factors will have a direct impact on weed control and lawn health. Some of these factors are mower choice (whether it’s a z-turn or a reel mower), and most importantly, mowing at the right height for your particular grass type.

Prevention is all good and well. However, if you’re facing an overgrown lawn where weeds now outnumber your actual turf, then it might be the right time to bring out the big guns,

The Types of Weed Killer for Lawns

Weed killers, or herbicides, can be one of two classifications:

1. Selective

Selective weed killers are herbicides that target specific types of weeds. Consequently, this type of weed killer may be useful for a particular weed, say crabgrass, but may not be work at all with creeping charlie. This classification is the reason why it’s important for you to determine the type of weeds that are “squatting” in your lawn.

2. Non-selective

Non-selective weed killers, on the other hand, are typically broad-spectrum herbicides that makers formulate to work against most types of weeds, including grass. So, with non-selective weed killers, you’ll be able to spot-treat patches of weeds, decimate entire areas of unwanted grass, or both.

However, due to its wide-ranging effects, you’ll need to take more care when handling these types of weed killers.

Both of these weed killers may have pre or post-emergent traits or a combination of these two capacities.

You can use weed killers with pre-emergent capabilities to prevent the growth of immatureweeds or saplings from progressing to maturity. On the other hand, post-emergent weed killers primarily target mature plants.

*Important Note:

· Store weed killers correctly

Excellent weed killers can cover areas up to 25,000 square feet with just a single 1-gallon container. However, you must keep them away from direct light, and ensure that they are sealed tight, so their efficacy will keep for much longer in storage.

· Safety measures

Always, always, always thoroughly read the labels on any herbicide or weed killer you choose to use on your lawn. This way, you’ll know the proper way to use and apply this otherwise toxic chemical. Lastly, ensure that you wear protective clothing, such as goggles and nitrile rubber gloves when handling any herbicide.
