Do you know that your garden clay soil is more than just dirt?

When you examine your garden soil closely, you will notice a complete mixture of mineral particles, organic material, living organisms, moisture, and nutrients.

Among the most crucial factors is the ability f your soil to grow plants in its texture.

Moreover, the size of the mineral particles dictates their growth.

An important thing here to understand is the ideal gardening soil is loam or loamy soil.

It is a broad mixture of sand, clay, intermediate mineral particles, and a heavy dose of organic materials.

Thus, depending on the size of the particles, the texture of your garden soil can vary from porous or sandy to extremely dense and resistant to water movement,

Soit of this type is Clay soil and is termed so because its mineral particles are very fine clays.

Keep on reading to learn more about it in detail.

Clay Soil

Clay soil is a type of heavy soil that benefits from high nutrients and it can be very hard to grow a flower and vegetable garden in it.

Soil that contains about 50% of clay particles is referred to as “heavy clay”.

You can simply do a soil test to determine whether you have clay soil or not.

But, if your soil sticks to shoes and garden tools like glue, forms big clots and crusts over and cracks in dry weather, it is clay soil.

While some trees and shrubs can grow easily in it, most annuals, perennials, and vegetables do grow strong roots to fore their way through clay soil.

Moreover, if you are trying to grow spring flower bulbs, then it will be impossible to grow them as most bulbs tend to rot over winter in clay soils.

However, you can make improvements to clay soil.

With some basic information and a well-designed strategy, you can grow flowers and vegetables as much as you want.

Advantages and Disadvantages of Clay Soil

Every type of soil has its advantages and disadvantages.

In the same way, clay soil has its advantages. Because of its density, it can retain the moisture in it.

Moreover, it tends to be more nutrient-rich than other types of soil.

For this reason, the particles that make up the clay soil are negative charges, which means that they attract and hold positively charged particles.

These particles include calcium, potassium, and magnesium.

On the other hand, in addition to its positive attributes, it also holds some negative attributes.

Some of these are:

Clay soil is slow draining, is slow to warm in spring, and compacts easily, thus making it difficult to plant roots.

Moreover, it has a tendency to heave in winter and to be alkaline in pH.

Improving Clay Soil

Improving the clay soil can be a difficult job, however, the continuous work you do can help to improve the structure of your soil.

Moreover, it can help to make it easier to work with.

Most of the work you will do is upfront, although some annual chores can help to prolong the improvement of the soil.

Therefore, it is best to improve the whole planting area all at other rather than to attempt to improve the soil in individual planting holes.

However, if you dig a planting hole, then drop in the plant, and amend the soil that you are using to backfill the hole.

But you have done nothing more than create an in-ground flower pot.

Gradually, the plant will begin to send the roots that will stop in their tracks when they reach the clay walls of the planting hole.

Thus, you will end up with a root-bound plant that will not grow as large or as healthy as it should.

Steps for the Improvement of Clay Soil

In order to amend your soil, start by defining the growing area of your garden bed.

However, if you are improving an existing bed, you can also dig out plants you want to keep and set them aside until your soil is improved.

On the other hand, if you are preparing a brand new bed, you will need to go through the basics of starting a new garden bed.

To make amendments, you will need to add 6 to 8 inches of organic matter to the entire bed.

Moreover, you can also add any organic matter that you can get your hands on.

Grass clippings as long as you have not treated them with chemicals, shredded leaves. rotted manure and compost all are ideal choices.

Spread your organic matter on the top of the soil and you will need to mix it into the top of 6 to 12 inches of the soil.

Dig it and mix it with a shower as it moves a lot of earth without pulverizing the soil particles the way tilling can.

However, if digging the earth is hard for you, you can also use a tiller to do the job.

After you are done, your garden bed will be several inches higher than it was before, however, it is not an issue.

It will settle over the course of a season as the organic matter breaks down and will continue to improve as microorganisms work to break down all the organic matter you have added.

You can also plant your flowers or trees immediately.

Plan to add more organic matter in the form of compost once or twice a year as it will continue the process of improving the structure of the soil and offset any settling that happens.

Things to Avoid for your Clay Soil

Most often, you might think to in order to improve the dense clay soil you will need to add the opposite kind of mineral material- sand.

This is because loamy soils are ideal garden soil and is a mixture of sand and clay,

However, it is important to note that when you directly add sand to the clay soil, it will resemble concrete.

Moreover, the reason why loamy soils are great for your plants is that they have a huge ratio of organic material in them which serves as a foundation for the sand and clay soil.

Without this organic material, it can be harmful to your plants.

Thus, in order to improve your clay soils, you will need to add compost and other organic material.

After planting them, water them thoroughly and they will need additional irrigations before the plants emerge.

One inch of water a week during the summers will prevent stunted growth and leaf scorch.

Moreover, apply water to the base of the plants or use drip irrigation during the first year.

Make sure that soil contains consistent and average amounts of moisture to promote growth.

It can also tolerate dry sites and is also drought resistant which makes it a good choice for warm and wide-spreading prairie meadows.
