Item #: D1099H
Helps Control Pests:
DWARF MARIGOLD (Dwarf Double French) Annual
Height: 6-16 in/15-40 cm Tagetes patula 9, 000 seeds per oz/g
CULTURE: Germination: 3 - 7 days at 75-80°F/24-27°C soil temp. Sow indoors in flats or pots April 1st. for mid June blooms. Sow seed about 1/4 in/6 mm deep, cover lightly with coarse vermiculite, or peat-lite mix, rather than soil. For best results use bottom heat (heating cables) and keep moist with tempered water, to maintain soil temp. Transplant into 3 in. pots about 25 days after seeding. Seed may also be sown in rows outdoors June 1st at soil temp. of 60°F/16°C. Transplant 3 weeks later 8 in/20 cm apart. Use a fungicide soil drench to control soil diseases. A systemic insecticide should be used twice a month, to control red spider mite. Low outdoor night temps. of 40°F/5°C may cause plants to turn purple and slow growth - plants should green up as temps. increase.
COMMERCIAL GROWERS: Sow 118 oz. 13.5 g. of seed for approx. 900 - 1,000 plants. Several sowings are possible to spread transplanting over a longer period. We make 3 or 4 sowings about 2 weeks apart, starting about Feb. 15th. until late April, for May or June blooms. Sow seed about 1/4 in/6 mm deep, cover lightly with coarse vermiculite, or peat-lite mix, rather than soil. For best results use bottom heat (heating cables) and keep moist with tempered water, to maintain soil temp. To bloom in paks sow Petite types 6 to 7 weeks before selling date. The Super French (Boy series etc.) should be sown 7 to 8 weeks before sale. Transplant seedlings into paks about 4 weeks after seeding. After transplanting, lower greenhouse growing temp. to 50 - 60°F/10 - 16°?C. Temps. lower than 50°F /10°C reduces growth rate and may affect the flowering date. We find that the newer Super French types may be grown at a cooler 50 - 55°F/10 - 13°C for shorter, stockier plants.
