Clay soil is a very peculiar material used in gardening and is commercially available in gardening shops. This is unlike any other soil because of its tough nature and very high density. So let us get into the details of improving your clay soil for better gardening and vegetation purposes.

How To Improve Clay Soil for Gardening?

You can improve the clay soil for gardening purposes by adding pine bark, gypsum, and soil amendments in the soil and also by poking the soil, using cover crops, and using the technique of mulching you can also try to place the right fertilizer.

Clay soil is a very peculiar material that is used to grow plants and vegetables like broccoli because of its compact, thick, and high-density texture. The clay soil consists of 30 percent of clay particles, making it unable to trap any air or let any air pass through it, you must aim to improve it because your plants will thrive with this.

This can cause severe drainage problems and make it hard for gardeners to plant or grow grass, vegetables, or plants. This is why it is very important to improve drainage and the texture of the clay soil to make it feasible for use in gardening.

Still, this soil can be used by using various techniques of improvement. The plants like roses and other bulb plants grow best in clay soil. Following is a list of materials and ways that you can use to improve the clay soil.

– Adding Some Gypsum

Gypsum is one of the best remedies for making clay soil workable and usable. Adding it to the clay soil will make it less compact and allow the air to pass through it along with water.

This is a material that comes in a powdered form, and you can go ahead and add gypsum powder to the soil in the ratio of two-thirds of a handful per square meter, and this would be a good choice to opt for. After that, dig into the soil to mix the powder in, and add some water.

Although gypsum is an effective remedy, it may take several weeks or even more for the soil to break down and adopt a more usable form. Alternatively, you can break up the soil into small pieces yourself. Break it down and add the powder from the top. Then, you have to mix it well and add water to it, which will let the broken-up soil absorb the salt readily.

Another way of using gypsum is by mixing the gypsum and water in the bottom of a pot and then adding the clay soil from the top. In this way, the gypsum solution will be carried up the soil by reverse osmosis, causing the soil to let loose, and the soil will show a proper improvement.

– Poke the Soil for Aeration

When you go ahead and poke, it is by far the most fun method of improving the nature of clay soil as it will be aerated well. It is known that the clay soil is so dense and thick that it does not even allow air to pass through it.

Moreover, you will check how now, it is time to see the necessity of needing to create holes in the soil that will allow the air to pass freely. This can be done best using a self-fashioned poking device like a long, pointed wooden stick or a drumstick.

Start by poking holes in the soil with the stick, but now, be careful as to not poke right through the roots or fruits that are planted inside it. In addition to this, make sure to not poke at the same place twice, as consistent pokes might cause the clay to break up into clumps. This is a very simple and easy method of improving the clay soil for garden use for any allowed vegetable.

– Placing Soil Amendments

In the market today, more than a hundred types of soil amendments are present, each with a unique quality. Choosing the right type of soil amendment is very important; only the person familiar with their respective soil can be judged on that.

Some of the most famous and commonly known amendments include compost, green manure, leaf mold, worm castings, and livestock manure. All of these can be used in the clay soil to give it a little more life and a little less thickness, and this way, it the quality will become better and much more convenient to use.

All of these amendments, if not all, are present in the gardening shops or can be purchased online. Some of these amendments may have a limited shelf life, so keep in check with the expiration dates. However, you need to be keen on expired products, as they may not be safe to use for your plants, so they will damage it instead of fixing it.

– Use a Cover Crop

Cover crops can be used to give life to the clay soil as they can penetrate deeper into the soil. The cover crops also reduce soil erosion and work towards enriching the soil.

These crops can be grown in the spring or summer, and they will help you in the process. Most cover crops are grown in the winter, so make sure to choose the perfect crop according to your climate.

– Use Mulching

Mulching is the process of mixing leaves in clay soil to increase soil quality. This comes after aeration, soil amendments, and cover crops are planted. Mulch is a great choice that you can have when you wish to increase the humidity and moisture content in the soil, and keep the right texture in the long run.Use Mulching with Clay Soil

The best way of mulching is by using dried-up leaves. This is a great way because it improves the content of your clay soil and helps you recycle whatever sort of leaves you have at hand.

Instead of leaves, people also used straws for mulching the clay soil. This worked perfectly before, but now the straw is heavily mixed with insecticides and herbicides, so their usage may not be that feasible.

Another great alternative to straw and leaves is Alfalfa hay. As Alfalfa is a legume, it may not be heavily sprayed with herbicides; as a result, it will make the medium a good alternative.

The use of mulching is also affected by the time of the season. In the rainy season, mulching should be kept at a minimum to let the soil breathe and perform its work. Whereas, in the summers and dry weather, mulching should be done heavily to give the soil much-needed protection.

– Do Not Walk On the Clay Soil

The last step of improving your clay soil is a very unusual one. To improve the clay soil and its properties, one should avoid walking on it at all costs. Do note that the texture will become compact when one steps on them, because already, the medium is heavy, so you shouldn’t make it denser by stepping.

The reason behind it is that walking on the soil will force it to become more compact and thick, both of the things that you are avoiding. So instead of walking directly on the clay soil, try to take an alternative pathway, and try to trace it.

Construct a small but sturdy bridge over the clay soil if the patch is longer or wider. You can also fashion a ladder above the patch for ease of access. Alternatively, you can make tiny pathways through the clay soil to avoid stepping directly on it.

All of these methods, when used in an appropriate way, will help you in improving the properties of clay soil. This will make the soil ready for implantation and general gardening. However, if you think that the clay soil is out of your interest and do not want to put in so much effort, you can replace that patch of land with normal soil from the shop.

– Check the Acidity

You can check the quality and the chemical content of your clay soil at home by using an at-home soil testing kit which is available at gardening shops or you can get them online. These testing kits are almost as accurate as the tests from the labs.Check Acidity of Clay Soil to Improve

The only downside to these testing kits is that they may not offer a full chemical check-up of the soil in one test. This means that for various concerns, you may need to test the soil multiple times on multiple testing kits that offer multiple specific diagnoses at any time. Nevertheless, you can check the quality of your soil at home in no time.

– Place the Right Fertilizer

When you aim to place the right fertilizers, they should be ones that are considered best based on the grade of ingredients used to make them and their effectiveness, because you shouldn’t use ones that will build up the salt content.Place the Right Fertilizer on The Soil

That being said, the nature of your soil also has a great effect on the way that the fertilizer reacts when added. So if one fertilizer works for someone’s garden, it may or may not work for your garden, which is completely normal.

You can choose either of the fertilizers that are good quality, as they offer good nutrition to the plant, but they differ in the time of the release of the doses. The inorganic fertilizer moves faster than the organic material, delivering nutrition faster.

Ultimately, the choice is yours; only you can decide which fertilizer is better for your plant. Both of these fertilizers come in a variety of ingredients, make, and prices. Make sure to test a little patch of land before you use it all over the clay soil.
