Marigold (Tagetes spp.) is a genus of the family Asteraceae. Marigolds can be grown in a wide range of soils, as they can easily adapt in different soil types, but they also need good conditions to be able to grow and develop. They can be planted in the beds for mass display or grown in pots. If the seeds are planted directly in the ground, it should be done in the spring, once the soil is warm. The plant does not require special maintenance measures, but it should be watered regularly. Regular measure of maintenance is deadheading marigolds to encourage the plant to produce more blooms and, in that way, extending the flowering season. The purpose of this research was to establish the difference between the growth and development in two different breeding mediums, the soil and the substrate. The experiment was set in 60 pots, 20 cm diameter. Half of them contained substrate Florabella, and the other half contained soil. In the period between June 14th, 2018 and September 2nd, 2018 variables followed blooming dynamics flowers marigold measuring (every 5 days) number of side branches, diameter of the stem and weight of fresh and dry above ground portion of the plant. By observing dynamics, development of vegetative buds, number of flower heads and diameter of flower heads were considered and observed. At the end of experiment we measured height of the plants, number of side branches, diameter of the stem and weight of fresh and dry above ground portion of the plant. The results of the soil and substrate for seedlings and flowering development have shown that the used soil had a weaker effect on the growth and development of velvet compared to the substrate intended for flower buds.
