Using nutrient-rich soil

Start by using a high-quality seed-starting or potting soil that is well-draining but retains moisture. These soils are typically formulated with a good balance of organic matter and nutrients. Avoid using heavy garden soil, as it may compact and hinder root development. If desired, you can also enrich the soil with organic compost or vermicompost to provide additional nutrients.

Applying fertilizer

While most seeds contain enough nutrients to sprout and develop their first set of leaves, they may benefit from a light dose of fertilizer once they have emerged. Use a diluted, balanced liquid fertilizer or a slow-release granular fertilizer specifically formulated for seedlings. Be careful not to over-fertilize, as this can damage delicate young roots.

Organic methods of providing nutrients

If you prefer organic gardening methods, there are several options for providing nutrients to your seeds. You can incorporate organic amendments, such as compost, aged manure, or worm castings, into the soil before planting. These natural fertilizers slowly release nutrients as they break down, nourishing the seeds and promoting healthy growth. Additionally, organic liquid fertilizers, such as fish emulsion or seaweed extract, can be applied as a foliar spray or diluted in the watering regime.
