As well as testing a variety of grass seed blends, we also based our recommendations upon plenty of research and a number of factors. The factors that we considered included the blend’s contents, coverage, growth rate/germination, durability, inclusion of an applicator, box sizes and value for money.

Conclusion

There are hundreds of grass seed blends available but it’s vital that you choose a blend that’s designed for the UK. Unlike other countries around the world, we aren’t that lucky to have gorgeous weather all year round.

For the best possible chance of growing grass successfully, you will want to plant them at the right time, which is usually from March to September. You should also prepare the ground by keeping it moist and removing any weeds.
