Can Weeds Grow in Sand? (And How to Stop Them)

Yes, weeds can grow in sand if left unattended. If you don’t take care of them beforehand, they can quickly populate an area and become a nuisance to your plants. Weeds can grow on any type of sand, and in this brief guide, we’ll show you how to manage them correctly. 

Can Weeds Grow in Sand?

Like grass, weeds can grow in sand. The difference between soil and sand is that sand cannot hold nutrients correctly. While they can grow in sand, the weeds will have to work harder to grow there. 

If you currently own sand, there is a chance that the beach salt will kill the weeds. However, the salt might damage the plants that are sensitive to salt. Basically, the salt will kill the plants, but the weeds will continue to grow from the roots. 

How to Keep Weeds From Growing in Sand

To prevent weeds from growing on sand, it’s best you get protective gear first. Start by wearing long sleeves, gloves, long pants, safety goggles, and a dust mask, so your eyes aren’t damaged. 

If you’re going to trim or workaround plants before or after eliminating the weeds, take time to clean your cutting and digging tools via a household cleaner (Lysol) or rubbing alcohol. 

Removing Weeds Manually

Since sand has a loose texture, it’s easy to remove weeds from it manually. You can use a rake, a stirrup, or a hoe to uproot your weeds and remove it from the soil. However, weeds such as dandelions are deep-rooted, meaning that they require a blade or a pulling tool to loosen up the sand before you uproot the weeds. 

This can be a strenuous activity, especially if you’re a senior gardener. While removing weeds manually is a  good skill, it will be more difficult as you age. We’ll explain more about herbicides in the next section. 

Chemicals and Herbicides

Using chemical-based herbicides is necessary if a large group of weeds is growing in your lawn. If you plan on using herbicides on sandy soil, make sure that you’re careful if the water is high. Herbicides like imazaquin and atrazine products can travel via the soil and can potentially damage the groundwater. 

Pre-emergent herbicides are effective at killing weeds before they grow into the soil. While the herbicide doesn’t stop germination, they do halt the growing process. Also, they aren’t effective on weeds that are actively growing. 

One disadvantage of using preemergent herbicides is that they can interrupt the germination of vegetable, grass, and flower seeds. On average, you should wait approximately four weeks after applying it to your soil or sand. 

However, you should use post-emergent herbicides on actively growing weeds. Some of these herbicides target grassy or broadleaf weeds. Other herbicides such as glyphosate products will kill desirable plants and weeds quickly.

For optimal results, avoid using weed killers on windy days, as the herbicide will endanger the entire landscape. 

Use Artificial Grass

Instead of always fighting to pull weeds from your lawn, you can opt to use artificial grass instead! What was previously viewed as taboo, artificial grass is starting to become a good alternative to natural grass. 

One benefit of using artificial grass is that it creates an attractive lawn and is low-maintenance. It is also a good choice for pets and children as it allows them to run on the grass, unlike natural grass. 

Artificial grass is durable enough to withstand a wide range of uses, and it won’t be discolored by dog urine. Using this form of grass removes the hassle of pulling out weeds, and you don’t have to worry about mowing the grass either. 

Add Mulch

Can weeds grow on sand? You can prevent this from happening by adding mulch to the area. Mulch is an attractive landscaping option, but it can also prevent weeds from growing and infesting your lawn. 

To apply, add bark mulch (2 inches). Adding too much will starve the soil of oxygen, which is necessary for the plants to grow. You might find out that you might have to add more mulch every year, but that’s a better alternative than consistently pulling weeds out throughout the year. 

In addition, bark mulch is good at retaining moisture through your beds because it can slow down evaporation. This will help reduce the watering time as well. Bark mulch works well at keeping moisture in your flower beds because it helps reduce evaporation, which helps you save time on watering your lawn. 

In addition, bark mulch is good at regulating soil temperature. So make sure it remains cool during the summer by blocking it and insulating it during the winter. You’ll keep your plants protected from frost and ice through proper insulation. 

Reduce the Gap Between Shrubs and Plants

You can prevent weed growth by ensuring that your shrubs and plants are so close together that they block out any emerging weeds. It does this by blocking out the sun and denying the room the weeds need to grow. 

Usually, you can reduce the spacing from the plants by 25%. These recommendations will help the plant not touch anything until it reaches full maturity. So always plan out your lawn beforehand to ensure that your plants are protected from any growing weeds. 

Will Sand Stop Weeds From Growing?

Sand won’t stop weeds from growing. Instead, it will make the weeds grow at a slower rate than regular grass. Weeds will still continue to grow in your lawn, and the best way to prevent this from happening is through either natural methods or herbicides. 


​​Can Grass Grow Through Sand?

Grass can grow through the sand. That’s because the grass can be affected by other factors. For instance, the grass has microbes inside of it, and like plants, it can grow via photosynthesis. 

With photosynthesis, it states that plants are able to grow through direct (UVA, UVB) and indirect sunlight. This means that your grass will grow through your sand, especially once it receives water throughout the seasons.
