80 plants/ m2 or 7-8 plants/ft2
PRE-PLANTING
Soil: Well drained, loose soil with no clusters, at least 25 cm (10 in.) deep.
pH: 6.2 to 6.5 (plug); >6.5 (plant in production)
Netting: 2 levels
CE: 0.76 -1.25 dS/cm (1:2)
DISBUD
Consists of the elimination of all auxiliary buds. This work is essential to achieve the desirable flowering type. Disbudding is done in week 4 and a second and third disbuddding are done during week 7 and 9.
IRRIGATION

FERTILIZATION
A high nitrogenous fertilization can cause an excessive growth of the plants.After transplanting fertilize the first six weeks with a well balanced formula based onCalcium Nitrate. Then switch to a high potassium formulation. Marigold is sensitive to Calcium and Boron deficiency. Apply foliarly for 10 days, starting 10 days after transplanting.
TEMPERATURE
The ideal temperature is between 26 ⁰ and 32⁰C. The minimum night temperature must be 10 ⁰C. It is sensitive to frost.
HARVEST
The harvest should be done when the flower head diameter is 7 cm.Harvest with care. Stems are very fragile since they are hollow.
POST-HARVEST
Use AVB (o.5cm3 /Lt of Water). Mix very well and add AVB Booster (1 cm3/Lt of Water. Keep the flower in this solution for 4 hrs.Then hydrate for 4 hrs in CHRYSAL PROFESSIONAL 2 (10 cm3/Lt of Water).
