Weed killers for your weed-woes!

You look over the fence and your neighbour's garden, lawn, yard, paths, and driveway look beautiful, exquisite even. You can stare at them all day. Yours, on the hand, not so much of a beauty but more of an eyesore. The sole reason for this, weeds!

What do you do? You do not want to spend the whole afternoon bent over the weeds with your hands. The good news is that there is a faster way of getting rid of these annoying plants. A weed killer will deal with this problem and you will have a stunning and weed-free home.

Why give Weed Killers a Chance?

We all want to save time, no matter what activity we are doing. Be it at home or at work. The weeds in our homes are no exception to this rule. Weed killers are the fastest way to get rid of weeds compared to hand-weeding or using a tool.

With most of the weed killers, especially the ones we are recommending, they kill the roots too. That ensures that they don't regrow immediately afterwards and you are back to spraying within a week or month.

What Should You Look for When Buying a Weed Killer?

Getting the ideal and effective weed killer will not be easy. The market is full of many options, with confusing chemicals and working time frames. How do you narrow down to a weed killer that is effective in the area with weeds? How sure are you that the time frame on the label is true? So many decisions to make!

There are different types of weeds. Some are small, with large or tiny leaves and roots. Others are large, with deep roots, making in an extreme sport to get rid of them even if you're using a tool. When shopping for a weed killer, your choice should be able to eliminate the leaves and the roots all at once.

Not forgetting how fast you want the weeds to die. Most weed killers will promise fast results, but the time frame will differ. Some work within 24 hours while others take weeks to produce visible results. This speed also matters when you are looking for a biodegradable weed killer. Some degrade within a week and others might take a longer period. 

Once you know what you are looking for, in terms of effectiveness, areas of usage, working time frame, biodegradability, as well as your budget, choosing a perfect weed killer, will be easy. And, we are here with numerous choices to make it easier to shop and get rid of those weeds.

Always Think About...

  • The type of weed killer, pre or post-emergent. A pre-emergent weed killer works on weeds that are yet to grow. However, you will need to know of areas where the needs will be or grow more often. Post-emergent weed killers are for weeds that are already grown, whether they just started growing or are a bit big in size.
  • Whether it is a contact or systemic weed killer. Contact weed killers will kill any plants they come into contact with. The results are fast, with the leaves withering in hours. Unfortunately, these only kill the leaves or the top part on the soil. Systemic weed killers, on the other hand, will find their way into the soil and kill the roots. This prevents the weed from regrowing.
  • Selective or non-selective weed killer. A selective weed killer is made for specific plant species, as the name suggests. They are ideal where you are worried about other plants around the weeds. Non-selective weed killers will kill any plant they land on, including your beloved flowers or veggies. These are not ideal for areas with plants you are worried about.

Finding the most effective weed killer might take time; a lot of researching, considerations, and, of course, minding your budget. With the above buying guide, you are close to finding the ideal weed killer. Better still, we have a list of effective weed killers available in the UK. Once you do your research and reference this, you will soon be spraying weeds out of your home.
