Procedure

Step One:

Pull the French Vanilla Marigold plant seeds out of their packaging and choose the desired amount that you want to plant. For our experiment, we chose to plant 16 seeds.

Step Two:

Fill 16 pots with soil and make sure the soil only fills up to about three quarters of the pot.
Once that has been done, separate your pots into two groups: 8 pots with one seed and 8 pots with two seeds. (If your experiment uses a different number of seeds, simply do however many you have chosen)

- Pots with one seed only ( 8 pots in total)

Dig a 1 centimetre deep hole directly in the centre of each of the pots. Place the seed into this hole and then cover it back up with the dug up soil.

- Pots with two seeds ( 8 pots in total)

Dig two 1 centimetre deep holes, but do not create them both in the centre. Instead, plant them   near the sides of the pot, and ensure the distance between the  two holes is at least 8 centimetres.

Step Three:

Water every individual pot with your desired amount of water. Make sure that the soil is moist and slightly damp, but do not over water the soil. This will cause your French Vanilla Marigolds to drown. Continue watering the flowers every day, but make sure the soil is not moist. If the soil is already moist, do not water the soil until the next day.

Step Four:

Place all of the pots in an area where they all get equal amounts of sunlight, or if this experiment is being done in a classroom, place them all equally under high powered lights that can act as a substitute for the sun.

Step Five:

Observe the French Vanilla Marigolds daily and water them when needed. Make sure they get enough sunlight and watch for aphids or pests.
