Learning Download: How to Grow Calendula
In addition to bringing a bright burst of color to the garden, Calendula flowers are grown to be used as a medical salve and the flowers are edible. The blooms are frost tolerant, which creates long-lasting color in the garden.
Before Planting: Calendulas prefer full sun but will grow in partial shade. They like rich, well-drained soil with a pH of 5.5 to 7.0, but the flowers will tolerate poor soil as well.
Planting: Sow Calendula seeds directly into the garden early in the season and cover with 1/4 inch of soil.
Watering: Water them during dry periods. Add mulch to retain moisture and deter weeds.
Fertilizer: Add compost to the soil to improve it and add a general-purpose fertilizer once a month.
Days to Maturity: Calendula flowers bloom from mid-summer up until the first frosts in the fall.
Harvesting: Prior to trimming the flowers and bringing them indoors to arrange in a vase, check for aphids.
Tips: Calendula is a good companion plant when planted near asparagus and tomatoes.
Our Seed Promise
"Agriculture and seeds" provide the basis upon which our lives depend. We must protect this foundation as a safe and genetically stable source for future generations. For the benefit of all farmers, gardeners and consumers who want an alternative, we pledge that we do not knowingly buy or sell genetically engineered seeds or plants.
The mechanical transfer of genetic material outside of natural reproductive methods and between genera, families or kingdoms, poses great biological risks as well as economic, political, and cultural threats. We feel that genetically engineered varieties have been insufficiently tested prior to public release. More research and testing is necessary to further assess the potential risks of genetically engineered seeds. Further, we wish to support agricultural progress that leads to healthier soils, to genetically diverse agricultural ecosystems, and ultimately to healthy people and communities.
