How to Sow Calendula: 

  • Sow outdoors in spring in any climate
  • In cool climates, sow indoors in spring for summer use
  • In warm climates, sow indoors in summer for fall and winter use
  • Cover the larger types 4 times their thickness in soil
  • Maintaining a temperature of 68-70° F
  • Germination takes 10-14 days
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Calendula: 
Spacing: Space seedlings 12-15 inchesvapart in rich, well-drained soil enriched with organic matter
Temperature: Plants thrive in sunny, cool climates; For best performance, grow 40-45° F nights
Soil:  Soil should be evenly moist and fertilized moderately
Additional Care: If growing Calendula in a greenhouse, sow in January for spring blooms or in mid-August for mid-winter blooms
Lifecycle:  Annual

Appearance and Use:
Long-lasting daisy-like blooms for cutting are borne on an easy-togrow plant used for edging, borders, containers, and greenhouses. Upright, busy plants reach 8-24 inches tall and 8-12 inches wide. Daisy-like 3-5 inch blooms of orange, yellow, or apricot arise from early summer till frost, in single or double-flowered forms. Oblong dark green foliage, 4-6 inches long, has a sticky texture

The best time to harvest flowers is in the summer, in the heat of the day when the resins are high and the dew has evaporated. Carefully dry flowers at low temperature in order to keep their vibrant color.
