How to Identify Weeds

Identification of weeds is the first step to removing them from your garden. There are multiple species of weeds that are hard to distinguish from grass and plants sometimes. People confuse overgrown bushes with weeds too, which makes eliminating weeds harder as they do not know where exactly to start.

Weeds have different species, just like plants, so every weed species has its own points of identification. It is not practical to know and look for markers for every individual weed species. But, here are some common weeds with their identification points that you should look out for in your garden!

  • Oxalis (Cup-shaped yellow flowers and clover-like light green leaves)
  • Cybergrass (Grassy appearance with seed heads spouting like four fingers)
  • Bindweed (Arrowhead-shaped leaves and pale pink flowers)
  • White Clover (Three-lobe leaves and round white flower clusters)
  • Nutsedge (Slender leaves with nutlike tubers in root system)
  • Lamb’s Quarter (Triangular leaves with gray undersides)

These are some of the weeds that grow in gardens most commonly. You should also look for any changes in the shape and size of flowers and leaves in plants that you are growing. This will also help you pick out any unwanted growths.

How to Identify Weeds

Types of Weeds

There are three types of weeds based on their life cycle – annuals, biennials, and perennials. Here is how each of these types differs from the other!


Annuals are the weeds that complete their life cycle once a year or sooner. They reproduce by seeds only, and form new plants when their stems are cut.


The biennial weeds have a life cycle of more than a year. But, their life cycle does not exceed two years.


The weeds that have a life cycle of over two years are perennials. They have creeping roots and tubers usually and are hard to get rid of.

How Fast do the Weeds Grow?

The rate of weed growth depends on the individual weed species, but they grow pretty quickly. Most of the weeds can grow 1 to 3 inches taller within a span of 24 hours. There can be an emergence of new weeds in as short a time as 12 hours. So, it is hard to offer you an exact estimate of the time that weeds take to grow fully.

Understanding the Growth of Weeds

Weeds seem to grow out of nowhere and invade your garden. While this holds true for many cases, there are certain factors that lead to the growth and spread of weeds. Their growth depends on environmental factors like sunlight and temperature. If a part of the soil is getting enough sunlight and water, its germination begins. This, along with the availability of nutrients in the soil, aids the growth of weeds further. Seasonal changes also affect the growth of weeds as they help maintain their annual, biennial, or perennial life cycles.

The Difference between Weeds and Bushes

Weeds are thought of as plants and growths that are unwanted in a garden. They grow rapidly and appear as part of bushes and shrubs sometimes too. So, it gets hard to differentiate them from the bushes that you actually want to grow on your lawn. Here are some key ways of distinguishing weeds from the bushes that you would be willing to keep in your garden!

Weeds vs Bushes – The Difference

Bushes and weeds might look similar at first glance, but they have many differentiating features. Weeds are unwanted, and they grow rapidly and aggressively. Whereas bushes are grown willingly, and their edges are trimmed frequently to maintain their shape. The leaves in bushes have alternate, whorled or opposite arrangements. But, weeds can have haphazardly arranged leaves, making them easier to distinguish.

Weeds vs Pests – What is More Detrimental

Weeds and pests are both harmful to the growth of plants in your lawn. They are both organic and can appear in your garden out of nowhere. Pests can be bugs, beetles, or fruit flies that eat the leaves and flowers of your precious plants. Whereas weeds consume the nutrients from the soil and weaken the roots of plants. So, basically, weeds are detrimental to the roots, while pests are detrimental to flowers and vegetables.

How to Get Rid of Weeds

Getting rid of weeds can be simple or complex, depending on the nature of growth. There are several ways of removing weeds from your garden. The simplest way of ridding your garden of weeds is to pull at them. This is great for weeds that are in the initial stages of growth. However, when the weeds have grown larger and spread around, then you need a battery powered weed eater or a gas weed eater to address such an issue.

Battery Powered vs Gas Weed Eaters

Gas weed eaters have been around for a long while, and people use them for large gardens. On the other hand, the battery powered weed whackers are better suited for small gardens.

Professionals who have to tend to large gardens prefer gas powered models as they can afford to carry extra oil and gas. In contrast, it gets more challenging for them to stop and recharge the batteries after 40 to 60 minutes of weed trimming. However, the best battery powered weed eaters save you from the trouble of carrying extra oil. The latest Lithium batteries can last a whole weed trimming session for small gardens.

Gas weed eaters have cutting swaths within a range of 16 to 18 inches. This enables them to cover more area while they are trimming weeds. However, the battery powered models have cutting widths of 10 to 14 inches. The battery powered weed eaters are environment-friendly, and they do not harm vegetables and flowers in your garden. So, the choice between a gas and best battery powered weed eater comes down to the size of lawn and the required efficiency.

How to Prevent Weeds from Growing in Your Garden

The best way of preventing the spread of weeds in your garden is to stop them in their initial stages. Prevention of weeds is not a one-time task, rather it is a continuous part of your gardening chores. Here are some ways of preventing weeds from growing in your lawn.

Avoid Unnecessary Tilling

Be cautious of awakening the weed seeds when you are cultivating your garden. Unnecessary tilling wakes the dormant weed seeds and initiates germination. So, it is better to avoid rigorous cultivating or tilling once you have established your garden bed.

Grow Plants Closely

Weeds grow the most in places left bare between plants. Make sure you plant the shrubs and flowers at a strictly necessary distance from each other. This leaves lesser room for weeds to grow and spread nearby.

Inspect New Plants Closely

When you bring in new plants from a nursery, they sometimes have weed seeds attached to them. You should look at the new plants closely before transplanting them in your garden.

Plants In The Cold

Some annual weeds grow in winters as most vegetables and flowers stay dormant in the cold. This gives weeds a chance to consume nutrients from the soil and invade your garden. So, you should grow cold season plants in your garden to prevent weeds from taking hold of the ground.

How to Use a Battery Powered Weed Eater

Using a battery powered weed eater is not that hard if you get the hang of the spin direction. When it spins in a clockwise direction, it cuts weeds from the left side and throws out debris from its right side. The use of a weed whacker also depends on the technique that you are using to eliminate weeds.

While scything, you will have to move the whacker in a shallow U-shaped curve. It is better suited for trimming grass-like weeds.

However, for screeding, you will have to tip the whacker in a way that its string-tips bounce off the pavement. This is ideal for weeds that have grown on hard surfaces.

How to Determine the Best Cordless Trimmer To Buy

With so many battery powered weed eaters on the market, it gets hard to choose one. However, you do not have to worry about it as we have enlisted the features you should look for in a high-quality weed whacker.

Line Diameter

Line diameter is the thickness of a trimmer line that a string trimmer can support. The thickness of the trimmer line is important as it affects the durability of the string. The thicker the trimmer line, the more effective it will be when it comes to cutting dense bush. Generally, a line diameter of 0.065 inches is considered ideal for weed whacking for lawns, so you should go for it.

Cutting Swath

Another thing that you should be mindful of is the cutting swath or cutting width. This is the length of weeds that a weed whacker can eat at once. Greater cutting width increases the efficiency of a weed eater as it reduces the time required to cut weeds. On average, a cutting width of 10 to 12 inches works fine for residential gardens and lawns.


Runtime is also an essential factor to bear in mind while you are comparing available battery powered string trimmers. The battery of a weed eater should last for 30 to 45 minutes once you have charged it completely. This gives you enough time to whack the weeds from your garden without having to take breaks to recharge it.


The handle of a string trimmer is also significant to consider. The handle should have a soft cover to help you grip it without any difficulty. You should also prefer the weed eaters that have ergonomic handles, as they prevent arm fatigue.


A weed whacker should be lightweight and compact, so that it is easier to control its movement. The lightweight weed eaters are easy to carry and store too. So, you should choose a weed eater that is lightweight and portable.

Length of Trimmer

You should be considerate of the length of a trimmer too while you are looking for a string trimmer. Some trimmers have adjustable lengths, which you can change according to your height. This helps you to get rid of weeds without straining your back.
