Seed balls are a great permaculture technique for growing seed in a more simple and effective way. This technique has been applied to make wildflower seed balls, as growing wildflowers from seed can be super challenging - they are slow to germinate and grow, and as a result are especially vulnerable to seed and seedling predators. Our goal is to make it a bit easier for everyone to have gardens, balconies and window boxes that are bursting with native wildflowers, buzzing bees and beautiful butterflies.
Each seed ball contains a mini ecosystem: seeds are mixed with clay, peat-free compost and a smidgen of chilli powder, and rolled into a small ball. Each ball is approximately 1cm in diameter, making them super easy to scatter.
The dried clay acts as a protective casing from common seed predators (such as ants, mice and birds). When sufficient rain permeates the clay, the seeds inside begin to germinate - helped along by the nutrients and minerals contained within the balls. The chilli powder continues to deter predators while the seed ball slowly degrades and the seeds sprout.
