4 Reasons Why Weeds Are Bad For Your Plants

Imagine your pretty plants, minding their own business, soaking up some sun and gently waving in the breeze.

Then, cue the dramatic music: A sinister tendril sneaks across the ground, wraps itself around your pretty plant, strangling it in a vicious death grip. 


This isn’t a horror movie, so put down the popcorn. It’s a real life weed called field bindweed, one of the most common weeds in Idaho.

Do weeds kill plants? You bet they do. 

Why are weeds bad for plants? OK, you can grab that popcorn again while you keep reading and find out.

1. What Do Weeds Do to Plants? They Steal

Weeds rob nutrients from the soil that your plants need to thrive. That means your flowers and plants won’t grow to their full potential. Weeds grab the water your healthy plants need, too.


2. Weeds Are Home to Pests

Harmful garden pests use weeds as their sturdy little hangouts. 

So when you allow weeds to grow in your garden, you’re providing a free bug Airbnb while they plot to munch on your unsuspecting plants.

3. Weeds Take Up Valuable Space

Why are weeds bad for plants? Weeds are great at crowding out healthy plants, hogging the space where they should be flourishing. Not only that, some weeds even secrete chemicals into the soil that interfere with the growth of surrounding plants.


4. Weeds Compete for Sunlight

What do weeds do to plants? If they grow big enough — and lots of weeds do — weeds shade your plants and steal the sunlight they need to thrive. Sun stealers! Does it get much worse than that?!

How to Stop the Effects of Weeds on Plants

What do weeds do to plants? None of it is good.

What to do about it?

First, Battle Weeds with Pre-emergent

Pre-emergent weed control is a crucial step in battling weeds.

Unlike other weed control products that kill weeds that have already sprouted, pre-emergent herbicides work ahead of time, preventing seeds of unwanted plants from sprouting in the first place. They target the weed seeds before they have a chance to germinate.

When you want to stop the effects of weeds on plants, timing is everything. It’s important to apply the pre-emergent herbicides early enough because if you wait too late, they won’t be effective. Here in Idaho, we typically start applying pre-emergent around April 1.

A villain that would actually steal the sun is obviously a super bad dude. So pre-emergent herbicide often isn’t enough to battle weeds. Some will still sneak through, laughing their evil villain laughs.

Once weeds have broken ground, use post-emergent herbicides to control them.

But weeds being weeds, they don’t make it easy. You need to know what you’re up against.


Weeds can be either grassy or broadleaf, with each kind requiring a specific treatment plan. Once you know what type of weed you have, you can take action with a weed killer that targets it. 

Better yet, let the pros do it for you, and hire plant health care services in Idaho Falls, and Boise, ID. 

Professionals have access to weed control products you can’t use without a license. And they can custom mix products or mix them in higher concentrations than the pre-mixed products homeowners can buy at the store.
