How to Sow Wildflower Seed Mixes
Prepare the site by clearing any existing vegetation and weeds from the planting area.
Mix seed with sand to ensure even distribution across loose, sandy soils.
Broadcast the seed evenly at the recommended rate (3g per m²).
Lightly firm the seedbed by rolling or treading to improve seed-to-soil contact.
Water regularly until the seeds are established. Coastal areas may need additional watering in dry periods.
Avoid fertilising, as wildflowers thrive in nutrient-poor conditions.
