Marigold Seeds
Native to Mexico and Central America and also believed to have been bred by the
Aztecs and Mayas for religious use, Marigold seeds have enchanted generations with
their colors of the sun and their drought tolerance. They prefer a warm, sunny
location and well-drained soil. Sow indoors 4-6 weeks before or outdoors after
the last frost. Space tall varieties 14"-20" apart; dwarf types 8"-12" apart.
All of our Marigold seeds are detailed seed, meaning that their tails have been
removed for easier sowing.

Tips on How to Grow Marigold Seeds
Germination Optimum conditions for seedling development that begins the day
the crop is sown until cotyledon expansion.
Expect radicle emergence 3 � 8 days.
Cover: Seeds may be covered with a thin layer of medium vermiculite to
maintain moisture levels.
Media: � pH: 6.2 � 6.5. pH levels <6.0 may induce iron, manganese or sodium
toxicity in Marigolds. Symptoms are exhibited on the lower leaves.
Marigolds can be used as an indicator plant for low pH.
Light: Light is not necessary for germination. If utilizing a chamber, providing a
light source of 10 � 100 foot candles will improve germination
Dramatically compared to seed germinated in the dark.
Moisture: Saturated for days 1 � 3 or until radicle emergence. On days
4 � 7 reduce moisture to moist . Once actively growing, begin alternating
between moisture levels wet and medium . Allow media to approach
dry before re-saturating to level .
Humidity: 100% until radicle emergence then reduce to 40%.
Dehumidify: Provide horizontal airflow to aid in drying down the media
through evapotranspiration, allowing better penetration of oxygen to the roots.
Temperature: 72� � 75�F (22� � 24�C)
Average Daily Temperature (ADT): 67�F (19�C)
Finish Bulking/Flower Initiation � Optimum conditions during the vegetative
period, beginning at transplant, needed for the root to reach the edge of the container;
AND to make the plant receptive to flower initiation.
Media: � pH: 6.2 � 6.5 Marigolds can be used as an indicator plant
for low pH conditions. Typical symptoms of low pH <6.0 include
yellowing of lower leaves, or browning/burning of leaf edges.
Light: Provide 3500 � 4500 foot candles
to hasten flower induction. Supplemental lighting under low light
conditions at 350 � 450 foot candles will enhance shoot
and root growth.
Temperature: 55� � 65�F (13� � 18�C) nights, 65� � 70�F (18� � 23�C) days.
Heat stress will encourage flower heads to be reduced in size. New growth will appear
�bleached� when temperatures are too cool in early Spring. Plants will �green
up� once night temperatures are increased.
Average Daily Temperature 67�F (19�C)
Humidity: 40 � 70%
Dehumidify: Provide horizontal airflow to aid in drying down the media
through evapotranspiration, allowing better penetration of oxygen to the
roots.
Light: Full sun.
USDA Hardiness Zone: 10.
