You can sow these wild flower seeds as soon as you get them directly into the ground where you want them to grow. Do not add compost or fertiliser to the ground as, like most native meadow plants, they do not require a nutrient rich soil. Rake lightly in to cover the seed and water regularly during dry weather to help establish the young plants. If sown between September and October you should expect flowering the following year.
Keep well watered in dry periods after sowing to help establish the seedlings.
