I bought the packet of Marigold Cupid Dwarf Mixed seeds from Twigland
Garden Centre. It contains approximately 125 seeds but I just planted
10 seeds for Summer 2016.
Marigold Cupid - a compact dwarf plant with large, softly curled flowers in yellow, gold, and orange.

More than just a pretty flower, marigolds
protect your garden vegetables from unhealthy nematodes that cause
deformities and disease. Grown as an annual, marigolds are propagated by
sowing seeds in the spring. You can collect the seed heads after the
flowers are spent so you have fresh seeds for the following growing
season. The process of removing dead flowers from the plant is called
deadheading; it is beneficial because it promotes more flowering in the
plant. After you harvest the dead seed heads, there are a few things you
must do to ensure a healthy production of marigolds next year.
Collecting Seeds
Gather
the dead seed heads from the marigold plants by cutting them from the
plant with pruning shears or scissors. Spread the seed heads on a drying
tray and set the tray in a shady area that has good ventilation. Allow
the seed heads to dry completely before removing the seeds. This may
take anywhere from seven to 10 days.
Move
the seed heads from the drying tray to a flat work surface. Firmly grip
the dried petals of the seed heads and hold the bottom with your other
hand. Pull the petals out of the dried receptacle. The parts that look
like tiny black carrots are the seeds. Separate the seeds from the rest
of the flower parts.
Place
the seeds in an airtight container and label the container with the
date and variety of the marigolds. Store the container in a cool, dark
place until six weeks before the growing season starts.
Planting Marigold Seeds
Fill
a propagation tray with a good quality potting soil. Moisten the soil
completely and allow the tray to drain. Make evenly spaced holes about 1
inch apart in the planting medium. Remove the marigold seeds from
storage and place two seeds in each hole. Cover the seeds with a fine
layer of soil.
Cover
the tray with a clear lid or clear plastic film. Set the tray in a warm
place that receives bright light. Use a grow light that is suspended
about 6 inches above the tray if you do not have a bright window.
Remove
the tray lid or plastic film after most of the seeds have germinated.
Thin the marigold seedlings to one healthy plant per space when the
plants have their first set of true leaves.
Leave
the seedlings in the bright light and do not allow the soil to dry out
while the seedlings grow. Avoid wet soil or the seedlings will suffer
from stem rot. Rotate the tray every other day to promote even growth
among the seedlings.
Pinch
off the top of the seedlings when the plants have at least four sets of
leaves to promote bushy growth. When the marigolds are about 4 to 6
inches tall, start the outdoor acclimation process.
Acclimation and Planting
Move
the marigolds outdoors in a shady part of the garden for about an hour a
day. Increase the amount of time in the garden every few days. Move the
flowers into the sun gradually, moving the tray from shade to partial
shade and finally into the full sun, as you acclimate the flowers.
Water
the marigolds from the bottom each morning to avoid sunburn and powdery
mildew. Move the plants into the shade at the first sign of stress:
wilting, drooping leaves or color change.
Plant
the marigolds in a prepared garden site that has been tilled to a depth
of about 6 to 8 inches and amended with a layer of compost or other
organic matter. Space the plants about 8 to 10 inches apart. Increase
the spacing by 2 inches if you grow a large variety.
