Best Buy composts for sowing seeds
By Adele Dyer
Seeds are self-contained packages that have everything inside them to germinate and start to grow. They just need fine, well-drained compost.
Our Best Buy composts for sowing seeds all grew great seedlings. Almost all the seed we sowed germinated and then grew on to make robust young plants.
Best composts for sowing seeds
A great compost for sowing seeds should have a fine texture that will surround the seeds with everything they need: water to kick-start germination and help the plant to grow; air to help the plant to mature, and a small amount of nutrients to fuel growth once the seed has exhausted its own stored nutrients. All our Best Buy composts give seeds all they need for strong, healthy growth.
Each year, we test a wide range of composts by sowing a large seed that is usually easy to grow, and a small, fine seed that will be a little more tricky to germinate. This year we chose sweetcorn 'Lark' as the large seed and petunia 'Express Rose' as the small seed, sowing 25 seeds of each in quarter-size trays. When the majority of seedlings are at the first two true-leaf stage, we count the number of seeds that have germinated and rate the seedlings for size and vigour.
