7 reasons to sow grass seed in autumn

    1. Better Conditions: Soil is much warmer; the air is cooler, and there is more rain. This provides better conditions for germination.
    2. Fewer Weeds: Weed seedlings are more rampant in spring, so your autumn-sown grass will have less competition as it establishes.
    3. Ahead of the game: You are ahead of the game for next season. This means there is no need to reseed in spring since you will have an already established lawn.
    4. Ready for summer: Sowing in autumn means your lawn will develop over winter when you use your garden less. Sowing in spring means your lawn will still be developing in summer, at a time when you want to make the most of your garden.
    5.  Less water management: Spring sowing means you have to worry more about hot weather and water availability, as seeds need a constant supply. Cool autumn rain means less water management (and less work for you).
    6. Stronger established lawn by spring: Young grass plants have more time to grow and get healthy before next summer's stress comes. You are giving them a head start to be as strong as possible.
    7. Fewer greedy friends: There is a reduced risk of birds damaging seedbeds due to migration and the availability of other food during autumn and winter.
