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.
