When to Use Sand for Gardening?
Gardening is never easy, but if you have passion, choose the best soil for your plants as it is the only base for their rapid growth.
If your choice is sand, do not use it alone as it will increase productivity when used in a mix with other soil, mainly clay, but it depends on the plant you choose to grow as succulents love sandy soil.
Let’s understand the use of sand for gardening.
- Mix the sand with compost or peat at the seeding time as it will provide a soil-less mixture allowing a well-drained medium with air circulation for growth.
- Container soil compacts over time, so to loosen the ground, you can add one part of sand to your potting mix and a 50-50 ratio of sand and peat for cactus and succulents.
- It works best to loosen up the heavy soil like clay as roots cannot expand in tight soil, and adding sand provides porosity to the ground.
- Add sand with a pitchfork or aerator to the lawn to cure the hardening of soil due to waterlogging conditions.
The sands have large particles and are loosely arranged so are the best option for transplanting plants as the roots will not be affected.
What Kind of Sand is Good for Gardens?

Moreover, the sand can uphold the nutrients compared to other soil types.
2. Builder Sand
Another sand for indoor plants and gardening you can count on is the builder sand, preferred by most gardeners for their potting mix to their raised beds.

If you plan to establish a garden full of floras, try builders sand as it is readily available and more accessible for you to cope with because of its coarse texture.

However, it can be a good option for molded arts and children to play with because of its fine texture.

- Add compost mainly of plant origin or manure to increase the sand’s nutrition and water retention ability.
- You can mix 20% of river sand with the potting mix as a substitute for perlite for plants like succulents and roses and 50% for cactus and adenium plants.
- Mixing the silica sand in the potting mix of plants like epiphytes, air plants, and bonsai helps improve the soil’s drainage.
- Apply mulch over the garden plant if you have sandy soil, as it will prevent excess warming of the ground and evaporation.
- Use rotting material over sandy soil to improve the water holding capacity.
- Add coconut coir to the sandy soil as it quickly gets mixed with the sand and helps in holding nutrients to a certain degree.
- Adding granular fertilizer with a 10:10:10 ratio of N: P: K will fill the spaces between the sand particle, but remember to cover them to prevent erosion.
