There are various reasons why adding sand to garden soil is necessary.
First, you must check the soil type and water retention level.
Sandy soils do not retain a lot of moisture.
If you want to reduce the moisture content in the soil, you might consider adding sand to it.
To make it easy for plant roots to grow fast, sandy soil is ideal.
However, you must balance the soil and the amount of sand you add.
The goal should be reducing the moisture in the soil.
Sand addition to the soil, loosens it, allowing plants to develop an elaborate root system.
This exposes the plant to more nutrients and strengthens the stem to withstand wind and other external forces.
Sand also aerates soils, increasing the number of microorganisms for healthy plant growth.
Should I Add Sand To Soil?
When improving your soil, sand should be part of the ingredients.
However, not all soils require additional sand.
If your soil water retention is high, 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.
Coarse sand granules enable plant roots to access more nutrients, 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.
Adding sand to the existing soil reduces the soil density and loosens 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.
Mixing one part of sand with two parts of the garden soil gives you 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 a long to germinate, adding sand is the right time to loosen the soil.
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 done 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 whether to add or not.
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 unhealthy, 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 oxygenate the root system and allow water to permeate.
To be effective, adding sand to the vegetable garden should be done during planting.
You cannot add to plants that have already germinated.
You cannot mix the two well after they sprout; it affects root system development.
Vegetable root systems are shallow; 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, resulting in 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 significantly change the clay soil structure.
Adding sand to clay should be done when no other option is available.
Adding manure or mulch is better than sand to garden soil.
Benefits of Adding Sand to Garden Soil
By forming air pockets, sand can improve drainage and loosen the soil.
This is especially beneficial for plants like lettuce that have fine wire roots.
Despite its benefits, you cannot add sand to any soil.
When you add it to clay, the sand will attach to it, making the soil even more compact.
Furthermore, the soil’s ability to retain moisture is reduced by sand.
Because sand particles are significantly larger than clay particles, they are needed in smaller quantities to fill the same area.
Sand can be beneficial when combined with frequent fertilizing in high-quality compost because leaching could result in the loss of nutrients and minerals.
So if you’re considering adding sand to your garden soil, remember that the soil profile can be altered only when significant amounts of sand are added.
Sand to clay should be used in a ratio of 1:1.
This means that you must add one cubic meter of sand for every cubic meter of clay.
Sand’s ability to help water-logged clay drain better is a good idea, but it frequently works out horribly in practice.
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.
