Can Weeds Grow in Sand? (Yes, They Fully Can)

Weeds are unwanted plants that hamper the growth and nutrition of the main plant. They always grow beside the main crop, and these need to be removed in time, or else the new crops would be affected.

They also negatively affect human activities and agricultural production. They can grow anywhere in your garden, even in rocks, concrete, and even in clay.

But, can weeds grow in sand?

Yes, weeds can easily grow in sand. Whenever winds blow, weed seeds go directly into the sand, and after that with a little help from sun and water, roots will start growing in the sand. 

Though it may seem that you can never stop their growth, there are several ways to prevent the growth of weeds near the plants, even in sand. It is essential to control the growth of weeds as it would hamper the crop yield, thereby increasing production cost, impeding harvest, and resulting in poor quality of crops.

Can Weeds Grow in Sand?

Weeds can grow anywhere, even in sand. They can easily grow in areas where natural sand is used. When winds blow, weed seeds go deep into the sand, and with the help of sun and water, roots will start growing in the sand. 


Several factors allow weeds to grow in sand. Wherever there is sand, there is no shortage of sand and very less shade. Since weeds love sunlight, it increases their growth. Another feature of weeds is that they don’t need tons of nutrition to grow.


Since sand doesn’t have much nutrition and weeds are being cultivated, survivors can easily grow in the sand without breaking a sweat. With wind, they easily dock inside the sand, and roots form.

Weeds can also grow in unstable grounds, and since sand doesn’t bind well, they don’t provide a good grip for plant roots, thereby accelerating the growth of weeds. 

Advantages of weed growth in the sand

Sand is soil that provides excellent texture and lots of airspaces. So when sand is used as mulch, it protects the top layer from water loss and fungal infection. 

Challenges of weed growth in the sand

The main challenge of weed growth in the sand is that it will hamper the quality of the sand and thereby affect the growth of the main plants. Though sand provides good drainage, the weeds would still absorb most of the nutrients, sunlight, and water.

What is the best sand to prevent weeds?

Apart from those sand gardens, you would also see the growth of weeds at the paver joints. If their growth cannot be stopped, it will eventually crack the joints.

The best way to prevent weeds is to use polymeric sand so there would be no formation of weeds. This polymeric sand is a filler and forms a solid seal between the pavers.

This won’t let the weeds grow and prevents the patio from getting damaged. You can also use organic sand such as EnviroSAND, which would prevent weeds from growing.

Moreover, apart from your patios, if you want to stop the growth of weeds in the garden, you need to solarize the area of sand properly, which would prevent the weeds from growing. 

How to permanently stop weeds from growing?

There are several ways to permanently stop weeds from growing in the sand. If you use sand for agricultural purposes or simply to pave your patios, weeds can grow anywhere in the sand. However, do not worry, as there are ways to stop their growth.

  • Vinegar and Salt: These are the best two products easily available at home, which shall permanently stop the growth of weeds. The acid in vinegar flows deep down the sand and helps burn the roots of the weeds, preventing their further growth. The salt simultaneously kills the weed plant using the process of osmosis. You can mix them with water and spray them on the weed. 
  • Herbicides: Herbicides should be used very carefully and not in areas where pets and children play around. They stop the plant from photosynthesizing further or disrupting the cell membranes of the plant, which would stop the weeds from growing. This should be used as the final step, as these chemicals would kill other plants in your garden. 
  • Weed Barriers: Weed barriers are the best prevention method rather than a solution. They are added underneath the sand and prevent the growth of weeds on the top layer of the sand. 
  • Mulch: Mulch is a thick layer mixed with sand in your garden that stops the weeds from growing. They do it by preventing the seeds from going deep beneath the sand. 
  • Artificial Grass: They work on the same process as weed barriers and act as aesthetics. All you need is to layer the grass on top of the sand, and the weeds won’t grow further. 
  • Solarisation: If you are not someone who prefers to add chemicals, then solarisation is the best process to stop the growth of weeds. This is done during the summer by laying tarps on areas where weeds grow. This way, the heat is trapped beneath the tarps, resulting in the death of weeds and their seeds. This process takes around 4-8 weeks to execute. 
  • Pull them out: This is the most common method. However, it is not the permanent solution to stop weed growth in the sand. You can manually pull out the weeds from the sand in your garden, but it can be quite tiresome. 
  • Sufficient gaps between shrubs and plants: If there is enough space between the plants, then weeds won’t absorb the essential nutrients from the plants, so the weeds won’t thrive well.

What can grow in just sand?

It is a wrong notion that plants don’t grow in sand, and the best example is the cactus. Plants can grow in sand if there is an ample supply of water and sunlight. These plants are best known as psammophytes which are majorly trees and shrubs.

They have very few or no leaves at all, and the process of photosynthesis works in the plant’s stem. The best plants are Bearded Iris, Butterfly Weed, Lavender, Salvia, etc. The crops grown in the sand are carrot, beetroot, cucumber, muskmelon, watermelon, fenugreek, radish, etc.
