There are various reasons where adding sand to garden soil is necessary. You need to check the soil type and its water retention level. Sandy soils do not retain a lot of moisture. If you want to reduce the moisture content on soil, you might consider adding sand to it.
To make it easy for plant roots to grow fast, sandy soil is ideal. However, you need to balance the soil and the amount of sand you are adding. The goal should be reducing the moisture in the soil.
Sand addition to the soil loosens it to allow plants to develop an elaborate root system. This exposes the plant to more nutrients and strengthens the plant stem to withstand wind and other external forces.
Sand also aerates soils, and this increases the number of microorganisms for healthy plant growth.
Should I Add Sand To Soil?
When it comes to improving your soil, sand should be part of the ingredients. However, not all soils require additional sand. If your soil water retention is high, you need to loosen it up a bit. This is common with clay or sticky soils that tend to compact on watering or during the rainy season.
Adding sand to the soil in the garden increases air packets. Corse sand granules enable plant roots to access more nutrients as well as water and oxygen.
The granules help the soil to drain well to avoid logging since it loosens the soil preventing it from compacting. Here is when to add sand to your garden soil/
When you need to condition the soil, adding sand does the trick. By adding sand to the existing soil, you reduce the soil density and loosen it. This adds enough space for the plant roots.
When soil is compacted, there is no space for the roots to expand, denying the plant the required nutrients, water, and oxygen.
By mixing one part of sand with two parts of the garden soil, you get a balanced and aerated soil for your plants. The idea is to ensure the soil is more than the sand. The sand acts as a supplement to improve moisture retention.
Fast Seed Germination
When you realize seeds take long to germinate, this is the right time to loosen the soil by adding sand. Loose soils ensure a high germination rate since compacted soil delays weak seeds from sprouting.
Newly sprouting plants need space where root development is not restricted, and this can be speeded up by adding sand to the soil.
A suitable topsoil mix with sand provides growing plants with the necessary nutrients. The more nutrients, water, and oxygen they get, the better for fast root development. Not all soils required adding soils. It is up to you to decide to add or not to.
There are some soils that you cannot add sand to. Loam soil has enough sand, and adding more makes it worse. If you have this soil type and the plants are not healthy, adding manure should solve your problem.
Lack of proper nutrients may lead to weak plants. This happens to vegetable gardens that have been cultivated over several seasons.
Adding Sand To Your Vegetable Garden
Adding sand to your vegetable garden depends on the soil type, water retention level, and the type of vegetables you want to grow. Some gardens require more sand than others. However, sprinkling sand sparingly on the top soils does more harm than good.
When you sprinkle sand on top of the topsoil, you only compact the garden soil, and vegetables will not thrive. You need to add one part of sand and two parts of topsoil and mix thoroughly.
This ensures the sand granules create breathing space for the plant roots. They also help in oxygenating the root system and allow water to permeate.
Adding sand to the vegetable garden should be done during planting to be effective. You cannot add to plants that have already germinated. You cannot mix the two well after they sprout; it affects the root system development.
Vegetable root systems are shallow, and when adding the sand, it should be at least one foot deep. You can use horticultural sand, but the builder’s sand will do just fine if you do not have the resources.
Vegetables are annual, and compacted soil makes them stunted. This happens since plant roots are soft and tiny and cannot penetrate compacted soil.
Adding Sand To Clay Garden Soil
Sand has, over the years, proven to be the best amendment to clay soils. Adding sand to clay soils has its benefits. Due to its fine texture, mixing with sand improves the blending. However, it is not easy as it sounds to achieve an aerated and loose texture.
Clay requires a lot of sand to loosen up. To achieve the best results, you need approximately 4 inches of well-aerated sand that goes on 6 inches of clay topsoil. This is labor-intensive, but the result is loose soil with enough oxygen and a suitable moisture level.
When you add sand particles to clay soil, they tend to bond together. Instead, use 50 percent sand to make a significant change to the clay soil structure. Adding sand to clay should be done when there is no other option available. Adding manure or mulch is better than sand to garden soil.
How About Adding Beach Sand To Garden Soil?
Beach sand looks like normal sand on the surface, but its construction makes it unsafe to add to your garden soil.
This type of sand contains quartz and silicon dioxide, which do not allow free oxygen circulation in the soil. Whether cleaned of its saline properties, beach sand lacks the pockets to store nutrients that plants require.
In conclusion, sand plays a significant role in aerating garden soils. It helps plant rot systems to spread and reach more nutrients for plants to thrive. However, it is crucial to study the soil type to know the amount of sand required.
Adding sand to clay soil is very important and is known to improve water retention levels. It loosens up the soil giving it a better texture for plant growth. However, it is not advisable to add beach sand to your garden soil; it will ruin your topsoil and the plants.
