How to Keep Weeds Out of the Garden

When nature is allowed to take over your garden space, it becomes a survival of the fittest contest for plants. After a year or two of negligence, a garden bed will become overrun with fast-growing weeds.

These aggressive plants work by growing and spreading quickly. In doing so, they can suppress your vegetable seedlings in the process. There are many methods for weed control in the garden, but we prefer to only use non-chemical techniques.

In this article, we will share a few options for how to keep weeds out of the garden. Some require a little more elbow grease than others, so start with the method that works best for your situation.

How to Keep Weeds Out of the Garden

1. Cover With Black Tarp

Without sunlight for photosynthesis, most weeds will die off quickly. You’ll know about this if you’ve ever left a kiddy pool on the lawn for a few days – the grass below turns yellow and begins to die!

One of the simplest methods for killing existing weeds in the garden is to cover the area with a light-blocking tarp. A heavy-duty tarp will work best, but you can also use thick black plastic to block out all of the sun’s energy.

Note: This process is different from ‘solarizing’ a garden bed which uses clear plastic to allow sunlight to over-heat your soil to kill off weeds and bacteria.

It is best to do this during the late winter months when the garden is not in use, but can also be done during the summer if necessary. The process takes weeks to months, depending on how hardy the weeds are.


2. Use Mulch

When starting from scratch in a new garden bed, stay ahead of the weeds by mulching heavily around your crops. There are many different types of mulch that can be used to suppress weeds.

Types of Garden Mulch:

There are many additional benefits to mulching in the garden aside from weed suppression. One perk is an increased water retention in the soil beneath the mulching. The water near the surface of the soil will not evaporate as quickly and can be stored for use by your plants for longer.

Another benefit of mulching is temperature control. If you are expecting colder weather, a thick layer of mulch will help keep the root system at a consistent temperature. This is especially important for crops that are not cold-hardy (like peppers!).


3. Use a Weeding Hoe

We love this gardening tool for weed control. The simple tool has a long, wooden handle with a loosely-fitted, thin blade for cutting underneath weeds. The blade destroys weeds by slicing their root systems.

These are usually hard to find in stock at the local hardware stores due to high demand. We were lucky enough to find one at Home Depot, but they are available online at Amazon for a similar price.

The key with this tool is to use it on young weeds, before they can grow to be large with thick roots. If you are trying to tackle massive, overgrow weeds, the weeding hoe may not be up to the task. You just might end up with more blisters on your hand than it was worth.

In short, keep on top of weeding the garden with this slicing tool and your job will be a lot easier throughout the season!


4. Plant More Crops

One of my favorite methods for suppressing weeds is to plant more crops in your garden beds. Improper plant spacing can cause wasted soil space, inviting weeds to take over.

By spacing your veggies closer, and interplanting smaller plants in any gaps, your take up as much garden space as possible. Your plants shade the soil below, preventing any weed from dominating.

Plus, using your soil is great for keeping the soil microbiome healthy. The best soils are those that have plants growing in them at all times. It helps prevent erosion and protects valuable worms and microorganisms from harsh sunlight.


5. Hand Pull Weeds Regularly

If you want to go old school, you can of course hand-weed the garden. If you don’t mind getting your hands dirty and enjoy spending time in the garden, this process can be therapeutic and rewarding.

Again, the key here will be to stay on top of the weed control. As soon as they are allowed to establish a strong room system, hand-weeding becomes a much more grueling chore.
