In comparison to other types, sandy soil has more and larger particles. It is mostly found in desert landscapes.
Sandy soils get warm pretty quickly with the sun’s influence and can retain much less moisture. Additionally, it also lacks nutrients in comparison to others.
If you look at the sandy soil under the microscope, you will notice that it looks like a bunch of tiny marbles. Those little particles have a pretty large space between them. Because of this space, the nutrients are washed right through.
The particles are tiny rocks, and as we know, rocks do not hold water. That is why the organic material has to be added to the sandy soil.

Is Sandy Soil Good For Plants?
Sandy soil can be good for plants that have a very strong root system and like dry soil like Lithops. Sandy soils are characterized by higher levels of acidity, therefore the greenery that is planted in this kind of dirt must do well in an acidic environment. Such plants are root vegetables that have deep roots.
Allium Plants such as onions and chives have a higher chance of success in sandy soil. Herbs like thyme and rosemary are familiar to Mediterranean climates, therefore will also do well in the sand-dominated soil.
How To Improve And Make Sandy Soil Fertile
Because it gets washed out pretty quickly, the nutrients and minerals do not hold in the sandy soil. On the other hand, they are very needed for plant growth.
If you have sandy soil in your garden, then most likely, you will have to start thinking about how to improve its fertility.
One of the first things that you can do is to add organic matter. This will raise the moisture retention and by adding organic soil amendment, it will become more welcoming to the wide range of plants.
For this job, one of the best organic materials is vermiculite, coconut coir, and peat moss.
The second thing that you can do is to lay down one layer of mulch. For this purpose, grass clippings, wood chips, straw, tree bark, leaves, and manures can be used.
The organic matter that has a low level of nitrogen will have to be composted first and then added to the soil. However, if the organic material is high in nitrogen, they can be directly incorporated. By doing so, your soil will hold more water and excessive evaporation will be prevented.
Additionally, what you can do is grow cover crops. Those crops are also known as green manure crops. They increase the soil quality and help to retain needed nutrients and moisture.
Last but not least advice is to install the drip irrigation system. This way, the soil will be moist all the time, especially in the warm season. It is recommended to dig Sand-dominating dirt in the early spring or late winter.
Advantages Of Sandy Soil
Sandy soil can be much easier to care for in comparison to clay soil. and here is some of its benefits:
- It is easy to dig and amend.
- It has a loose texture and good air circulation.
- Does not get compacted and provides good drainage.
- Plant roots can establish and grow easily because of the low weight and less compatibility of the soil.
- Soil that has sand in it freezes late in winter and warms very fast in the spring. Therefore, it gives greenery more time to grow and establish.
- Over watering is not a problem when having sandy soil. Therefore, the issues such as root rot that are following over watering are avoided.

- Those are trees
- herbaceous perennials
- ground-covering plants.

- Butterfly weed
Vegetables include .
Sandy soil can be good for various plants. It has benefits such as being soft and providing good drainage. However, it needs to be managed differently from other types of soils.
