We're explaing how to sow a wildflower space using Grow Wild seeds, but you can use any UK native wildflower seed mix - read our advice on where to get wildflower seeds. Check how much space your seeds will cover and bear this in mind when choosing a site

You will need:
  • Garden fork or spade
  • Garden rake or fork
  • Watering can or jug
  • Wildflower seed mix 
  • Something to label your site with so you don’t forget where you’ve sown your seeds!
Follow these steps:
  • Choose a fine Spring or Autumn day when the soil is neither too wet nor too dry.
  • Dig over the soil with a fork or spade and break up or put aside large clumps. Remove weeds so the wildflowers don't have any competition, and any large stones. 
  • Rake the soil so it's fine and crumbly - lumpy soil may bury seeds; if it's too hard, roots will be unable to penetrate the ground. 
  • Ideally, leave your prepared soil for about two weeks so any dormant weeds or grasses that come to life can be removed before you sow your seeds.
  • Scatter your wildflower seeds over the soil by hand - a little at a time for an even spread.
    Top tip: to make spreading easier, mix seeds with a small amount of dry play sand or flour so you can see where you've sown them.
  • Rake the soil again - gently - to just cover the seeds with a very thin layer (1mm) of fine crumbly soil. 
    Seeds need sunlight, so be careful not to bury them or they won't grow.
  • Very gently, water the whole area using a watering can, taking care not to wash your seeds away.
  • Label the area with your plant markers (you could make your own!) and don’t forget to include the sowing date.

After sowing your seeds

If you're sowing in Spring, it's critical to water wildflowers in the ground regularly after sowing and while the seedlings are establishing in the first six weeks. You should aim to water your freshly sown wildflower space twice a week and more frequently in hot weather. Your seeds should germinate within a couple of weeks, depending on the weather. 

If you're sowing in Autumn, you only need to water your seeds once and then leave them over winter, when the seeds will be dormant. Come back to water them once the weather gets warmer and seedlings start showing.

When it is dry weather, make sure the soil remains moist and water. Seedlings can be killed if the soil dries out completely.
