Flower Seed (Annuals) Planting Information:

Annual flowers do best when planted indoors and transplanted outdoors when the danger of frost has passed. Plant your seeds indoors 5 to 7 weeks before setting them outside. For tiny seeds, do not cover with seed starting mix. Just sprinkle the seeds on top. Transplant them outside in the garden when seedlings are established. Plants can grow 1 - 3 ft tall.

Soil Requirements:

Requires rich fertile soil in a well drained location in the garden. Apply mulch, grass clippings, or straw around the base of the plant.

Water Requirements:

Water well during dry and hot spells.

Fertilizer Requirements:

Use Slow Release (6 Month) Fertilizer when planting outdoors. Periodically apply Miracle Gro.

Harvest Tips:

Snip the stems with garden scissors when the flowers are in full color.
