What are the differences between the types of compost?

The primary differences between different types of compost that you can buy are

  • The base materials
  • Whether the compost is organic or not
  • Which nutrients have been added to the compost
  • Whether the compost includes peat or not

What’s the difference between compost and manure?

Manure is organic matter and mainly consists of animal faeces.  Manure is NOT compost.  Manure on its own is not suitable for growing vegetables and is most definitely not suitable for growing vegetables in pots.  To use manure in vegetable growing it needs to be well rotted.  Fresh manure directly from animals is not recommended at all for vegetable growing.  Manure can, unless properly rotted and used can transfer disease.

Manure can be added to a compost heap or it can be added to a food garden 3-4 months before planting to help prepare the ground.  If you are a beginner vegetable gardener, then we recommend you read up on the use of manure in the preparation of ground and compost, but that in the short to medium term, you use prepared compost, there is plenty of choices.

What’s the difference between a grow bag and compost?

A grow bag is simply a decent quality compost with nutrients added.  Grow bags use good quality composts in thick large bags.  Grow bags are an excellent way to get started growing vegetables and are the perfect solution if you’re just getting started.  Using grow bags to grow vegetables can save you money as it means that you don’t need to buy additional pots and containers.  Stinting on good compost is not something we recommend.

What is the best compost for vegetables?

Vegetables need a lot of nutrients to grow to their best potential and taste.   Most beginner vegetable gardeners will not have soil in their garden that contains all the required nutrients for the best results.  All the easy vegetables that we recommend to grow here can be grown in compost.  Buying compost specific to vegetables includes nutrients that will give your vegetables the best chance of success.

Standard compost contains some nutrients, and you can also add specific nutrients that you purchase separately to aid your vegetable growing endeavour.  However, it’s also possible to buy specific composts designed for the vegetables that you are planning to grow.  Here are a few examples of the best veg composts

What is in compost for vegetables?

Compost that is specifically designed for growing vegetables contains specific organic matter and nutrients that are designed to support the vegetable plants.

Well rotted compost created naturally contains the primary plant nutrients – nitrogen, phosphorus and potassium.  Compost that you buy will include these nutrients in different amounts but also in a way that is designed to release the nutrients over some time.

Tomatoes grow well in multi-purpose compost, but also require lots of water, so compost that does not dry out is best.  Nitrogen-rich composts will also help tomatoes.  When tomatoes are fruiting you should check the dryness of the compost at least twice a day.  If you start tomatoes off inside you can move them and other vegetables outside in May.

Where to buy the best compost for growing vegetables

You can buy compost for growing vegetables from any garden centre or store that sells compost.   The best bagged compost for vegetable gardens has some great brand names such as John Innes, or own-brand versions.  We’d recommend ordering your compost online and getting it delivered to save on shopping trips – and, to be honest, compost bags and grow bags are heavy and a pain to transport.  Here are our recommendations for the best compost for growing vegetables online.

Why do I need compost for growing vegetables?

Using compost in either grow bags or in containers is quite simply the quickest and easiest way to get started growing vegetables.  You can ensure that the compost includes all the required nutrients to make your vegetable plants grow to their best ability and taste.  Using regular soil from your garden simply doesn’t contain the nutrients that vegetables need for proper growth and taste.  You can use soil from your garden, but you’ll need to either pretreat it with compost and manure (4 months before you want to use it) or add nutrients to it to get the best results.

It’s much quicker and more effective to use tried and tested composts that will increase your success rate in growing vegetables.
