Whether you’re filling your garden with vibrant vegetables, fragrant herbs, or beautiful flowers, mastering seed propagation is the first step toward a thriving, productive space. And when you choose heirloom and heritage varieties, you’re not just growing plants; you’re preserving history, biodiversity, and unbeatable flavour.Why Propagation MattersPropagation is the process of growing new plants from seeds, cuttings, or other plant parts. While there are many ways to propagate plants, seed sowing is the most accessible and rewarding method for gardeners of all levels. It allows you to select varieties that thrive in your unique environment and ensures a steady supply of homegrown produce.The Basics of Sowing SeedsChoose the Right Seeds – Opt for heirloom and heritage varieties to maintain genetic diversity and enjoy rich flavours not found in mass-produced crops. Pick the Right Growing Medium – Use a fine, well-draining seed-starting mix to give your seeds the best start. Sow at the Right Depth – Check seed packets for guidance, as some seeds need light to germinate, while others prefer to be buried. Water Gently – Keep the soil moist but not waterlogged. A fine mist or gentle watering can help prevent disturbing delicate seeds. Provide the Right Conditions – Most seeds germinate best with warmth (18–22°C) and consistent moisture. Some may need extra heat from a propagator or warm windowsill. Harden Off Before Planting Out – Gradually introduce young plants to outdoor conditions over 7–10 days to prevent transplant shock.The Magic of Heirloom & Heritage SeedsUnlike hybrids, heirloom and heritage seeds can be saved and replanted year after year, adapting to your local climate and soil. They offer a vast range of colours, flavours, and textures, making your garden as diverse as it is productive. Plus, by growing these varieties, you’re supporting seed sovereignty and ensuring that unique, traditional crops don’t disappear.Start Growing Today!Sowing seeds is one of the most empowering things you can do as a gardener.
