We recommend garden flower seeds be sown indoors in trays or pots first to give you good strong plants. Fill trays with potting or seed rasing mix. Sprinkle seeds thinly - do not cover fine seed. Cover larger seed with a layer of mix twice the seed size. Gently water and place in warm area. Keep moist. When large enough, thin or transplant to the garden.
Fill trays with moist mix to rim and lightly firm.
Don't sow all seeds just because they're there!
Mix seed with sand or mix for even sowing.
Cover seed with their own depth of mix. Don't cover fine seed.
Don't let trays dry out.
Harden off plants by placing them outside for a few days before planting.
