Growing vegetables in your garden is a fulfilling feeling but, if you haven’t done it before there are factors you need to consider for your project to work. Different vegetables have different soil requirements so the type of soil you use is a key factor in successful vegetable gardening.

There are many types of soils and mixes, so it’s important to know the right type for you. Before we get into the different types of soils, it’s good to know that most garden soils are amended. Soil amendment is creating custom soil mixes which help the plants grow and allow you to have control over what nutrients your plants are getting. For example, amending soil with organic matter, such as compost, is beneficial for all types of vegetables. Organic matter helps to improve the soil structure, increase nutrient content, and retain moisture, as well as reduce the soil’s pH, making it more suitable for growing vegetables.

So, what types of soils are there?

Loam soil is an equal mix of silt, sand and clay soil. It is the most fertile type of soil, meaning it has a great ability to sustain plant growth. It is ideal for any garden and growing most vegetables as it holds moisture but allows oxygen to reach the roots.

Clay-based soil is a type of soil that consists of small particles of clay. A lot of vegetables can’t grow in this soil, as their roots are not strong enough to get through the denseness, but it is good for vegetables that grow better in firm bases, like brussels sprouts and broccoli. Clay-based soil should be amended with organic matter to keep it light and airy.

Silty soils also consist of small particles, but from naturally eroding rocks. These soils are likely to be highly fertile as these particles have a high capacity of holding nutrients like calcium and magnesium. Silt is great at holding water and oxygen and is nutrient-rich meaning many vegetables can grow in it. Go for vegetables that require nutrient-rich soil, like tomatoes, sweetcorn and squash.

Sandy soil is dry and warm in the spring, it’s a good choice for early planting and sowing with the right amendment. It drains well and holds little water but is usually acidic and less fertile than other soil types.

Peat soil holds lots of moisture but no oxygen and is usually highly acidic and not very fertile. Alone peat is not expected to grow strongly but with mixes and treatment like draining, the soil can grow crops like lettuce and celery.

Chalky soils are alkaline and hold little water so they can easily become dry and difficult to keep fertile. It can grow vegetables that don’t have many nutrient requirements but it’s usually left for wildflowers to grow.

For the best results, you will need to create a custom soil mix for the nutrients and pH levels you need and separate your vegetable patches so that similar vegetables are together getting the right nutrients.
