Best Seed Sowing Compost UK 2023

Thanks for taking your time to read our information on the best seed sowing compost that is currently available on the UK market. It's important to give your seeds the best start in life by planting them in a good quality seed compost, that will aid in their germination and healthy growth.

In general most seed composts contain a lot fewer nutrients than all-purpose compost but a high amount of phosphate, thats essential for initial root growth. It can often contain leaf mould, or peat, and is generally finer so the shoots can break their way up through it easily.

Good drainage is a must and you might want to add a bit of sand into the mix to help this. A decent seed compost will encourage your seeds to germinate and grow, during the early stages. It is designed to promote formation of strong root systems and will work really well for cuttings too .It also makes sense to always check the requirements of the species, before planting.

What is the Best Seed Sowing Compost?

Any of these composts will do a great job for planting your seedlings and all of them have been specifically designed to help with propogation and the forming of a strong root system. It's important not to use a standard compost at this stage as there are far too many chemicals in a normal compost and it will probably do more damage than good.

We find that this type of seed sowing compost will improve germination by around 25% and will definitely give any plant or vegetable a much better start in life. Roots are really the most important part of a plant so getting a good start always makes a big difference.

We hope this has opened your eyes to the world of seed sowing compost and good luck with your gardening.

I am someone who enjoys a little gardening. Now I am not someone who spend hours in the garden, but I do like both my front and back gardens to look really nice. Well kept lawns, neatly trimmed hedges, and borders filled with plants, make a huge difference, to how your property looks.
