Learning Download: How to Grow Four O’clock
Four O’clock flowers get their name because they bloom in correlation with changes to light and temperatures, usually in the evenings between 4 and 8 p.m. They bloom in a trumpet shape with many different color varieties.
Before Planting: Four O’clock seeds don’t require pretreatment to germinate and sprout easily if planted in warm, moist soil.
Planting: Begin the seeds indoors up to six week before the last frost. Move the seedlings outdoors after the last spring frost, however use a hardening off process to slowly acclimate them to the outdoors.
Watering: Four O’clocks only need occasional watering.
Fertilizer: Plant Four O’clock flowers in rich, composted soil because they are heavy feeders.
Days to Maturity: Four O’clocks bloom from June through first frost.
Harvesting: Because of their short blooming period, Four O’clock flowers typically aren’t harvested as cut flowers.
Tips: Keep in mind, Four O’clocks are toxic compounds that can cause digestive issues or skin irritation.
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.
