How to Sow Wildflower Seed Mixes
Prepare the site by clearing existing vegetation and weeds in the coastal area.
Mix seed with sand to ensure even distribution, especially in loose, sandy soils.
Sow evenly at the recommended rate (3g per m²), using a broadcast method.
Firm the seedbed lightly by rolling or treading to ensure good seed-to-soil contact.
Water regularly during the establishment period, particularly in dry conditions.
Avoid fertilising, as wildflowers prefer nutrient-poor soils to thrive.
