What Is The Best Soil For Plants?

I am often asked – what is the best soil for plants? Of course the answer will depend on which plants are to be grown.

Whether you’re needing soil for the garden borders, containers, types of specialised soils required for particular plants, are all considerations that need to be addressed.

The best soil for plants generally and the most value for money are multipurpose composts.

There are also specialist composts for particular plants that need different mixes of nutrients and PH levels.

With all the environmental issues our beautiful planet is facing we need to make sure that the compost we choose is peat free.

There are any number of multipurpose composts with general PH levels and nutrient levels that are a good mix for many plant requirements now available that do not have any peat content. Here in this article I aim to give you the basics of soil requirements for a few different plant types. Mainly the multi-purpose, peat free composts will be more than adequate for all your general gardening needs.

Why Peat Free?

Peat is a natural product, it is made up of composted plants and moss in acidic and waterlogged bogs. It has been sourced and used for 100’s of years as a fuel.

It forms at such slow rates, 1 metre per thousand years that it is not a sustainable product. We are using it a lot faster than it forms, therefore it is not a renewable resource.


Peat bogs absorb and store carbon. Also, they sustain wildlife, plants and insects that have evolved to survive in the peat bog environment. They are essentially an important eco system.

It has been widely used in gardens as a soil improver as it is rich in nutrients.

But when peat is extracted in huge, commercial quantities we alter the eco system drastically. A peat bog is drained when extracting the peat. It dries out and will then die.

Habitat and food for the wildlife, insects and plants that rely on it is lost, resulting in further loss of the wildlife.

A dead peat bog will also start to release the stored carbon within it into the atmosphere with catastrophic effects on the environment.

The concern with gardeners in the past is that peat free compost products are not as good as those with peat, but now compost products carry the British Standards mark so you should be able to rest assured that you can source good quality peat free products.

All plants require good, healthy growing soil. Unfortunately not every garden has the perfect soil for the plants that you may wish to grow. Therefore, buying compost that are an ideal mix of nutrients and organic material is the best way of ensuring your plants are given the proper conditions in which to thrive.

  • Best compost for vegetable gardens

  • 100% Peat Free Compost
  • Great for topping up raised beds
  • Feeds plants for six weeks. Use a general fertiliser after the six weeks

Generally vegetables will grow in soils that are free draining and rich in nutrients. A crumbly loam soil that has the right balance of the three main requirements for strong healthy growth – Nitrogen, Phosphorus and Potassium.

Digging in organic matter will improve poor soils and give your vegetables the best possible start. Compost, well rotted manure, homemade composts and leaf mulch are all good organic matter that you can use. Not only does organic material add essential nutrients but it also helps to improve the soil texture, making it easier to dig and work with.

Clay soil particularly needs plenty of organic matter added. Planting vegetables in raised beds can help ensure the plants have the best growing medium in which to put down strong and healthy roots which will then be able to grow into the clay soil below.  Plants that Grow Well in Clay Soil

Homemade Compost

Being able to make your own compost is a huge bonus and I will encourage anyone to try to find space within your garden to do so.
Wooden compost bins can be made easily with old pallets or any wood planking that can be recycled.
Various compost bins are available on the market to buy
In some areas here in the UK councils provide them free or they have ones to sell

You need a good mix of wet and dry material –

Any cut back material from finished plants, shrubs, flowers, etc. Foliage, grass clipping, hedge clippings, kitchen waste from uncooked fruit and vegetables.

Wood ash, paper, cardboard, chipped twigs and small branches and autumn leaves.

The hotter you can get the compost the quicker the material will rot down. The heat is generated in the middle of the mix, so turning compost over helps to distribute the heat, aiding further break-down.

Do not add any diseased material as this will further spread the disease or virus.

I also avoid adding perennial weed roots.
