Each tin contains 20 seed balls, which will cover 3-5 medium sized pots – it’s best to keep at least 10cm between scattered balls. Each ball contains around 30 seeds containing salad rocket, kale, green and red mustard and cress. Scatter at any time from early Spring until late Autumn. Salad Mix can be grown indoors on a sunny windowsill (keep well watered) or in a garden bed or pot. We make the seed balls ourselves from our HQ in North London - from a mixture of UK native wildflower seeds, clay, peat-free compost and chilli powder. The clay protects the seeds from wildlife, and once water has permeated the clay, the seeds inside will germinate, helped along by nutrients and minerals contained within the ball. The chilli powder deters slugs and snails while the seed ball degrades and and the seeds sprout. All wildflowers are listed by the RHS as 'Plants for Pollinators'.
