You can use all-purpose sand in a potting mix, but it may not be the best choice. All-purpose sand is typically finer in texture and may not provide enough air space in the soil for proper drainage and root development. It can also create a denser mix, which can lead to waterlogged soil and root rot in plants.
Builder’s sand, also known as coarse sand, is generally a better option for potting mixes. It has larger particles that allow for better drainage and aeration. This helps prevent overwatering and promotes healthier root growth.
When choosing sand for your potting mix, it’s important to avoid plaster or fine sands. These types of sands can compact the soil and reduce air circulation, which can be detrimental to plant health.
Adding sand to a potting mix can be particularly beneficial for top-heavy plants that have a tendency to tip over. The weight of the sand helps provide stability to the container and prevents the plant from falling over.
Personally, I have used builder’s sand in my potting mixes and have seen positive results. The improved drainage and aeration provided by the sand have helped my plants thrive. However, it’s important to note that the amount of sand to add to your potting mix can vary depending on the specific needs of your plants and the type of soil you are working with.
While all-purpose sand can be used in a potting mix, builder’s sand or coarse sand is generally a better choice. It provides better drainage and aeration, which are important for plant health. Avoid using plaster or fine sands as they can create a dense mix that hinders root development. Consider adding sand to potting mixes for top-heavy plants to provide stability.
