Substrate plays a vital role in gardening, determining not only growth but also the overall health of plants. Whether you're an amateur gardener or a commercial grower, understanding substrates and their proper use is essential to a beautiful, eye-catching garden.

Wide range of options available

There is a wide range of substrate types available on the market, each designed to meet different gardening requirements. These can be broadly classified into organic and inorganic substrates. Organic substrates are derived from natural sources and include materials such as soil, compost, moss, coconut and composted bark. They generally have good water-holding capacity and are rich in nutrients, making them an excellent choice for plants that require a high level of organic matter.

Inorganic substrates, on the other hand, are artificial or mineral-based. They are often used in hydroponic systems or for plants that need good aeration and drainage. These substrates are usually inert, which means they do not supply nutrients, so you will have to add them yourself. Many substrates are also sold as mixes, so combine different types of substances to create a balanced environment for growing plants. Mixes are usually designed to provide an optimal balance between aeration, moisture retention and nutrient availability.

The importance of correct substrate use

First and foremost, the substrate provides physical support for the plant, anchoring the roots and facilitating their growth and spread. Substrate also plays an important role in supplying the plant with water and nutrients, and some products such as compost can also contribute to the overall fertility of the environment.

The correct use of substrate is essential to prevent problems such as plant drowning or nutrient deficiencies. For example, a poorly draining substrate can cause water to accumulate at the roots, leading to root rot and other associated diseases. Conversely, a substrate with too much drainage may not retain enough water for the plant, causing it to dry out quickly. The substrate also affects the pH of the growing medium, which can influence mineral uptake. Some plants prefer acidic conditions, while others thrive in a more alkaline environment. Using the wrong substrate can lead to pH imbalances that hinder the plant's ability to grow.

Choosing the right substrate and its benefits

Substrate selection should be based on the specific needs of the plants you are growing as well as your gardening method. Certain plants need specific substrates to thrive, orchids, for example, do very well in bark-based substrates, while cacti prefer a sandier, well-drained mix
