WaterCosmos, commonly known as the Garden Cosmos or Mexican Aster, prefers even moisture but can tolerate dry conditions once established. Water the plant deeply once a week, providing at least one inch of water, which is equivalent to about 0.623 gallons for a medium-sized plant. During hot, dry periods, you may need to water twice a week, ensuring that the soil is moist but not waterlogged. Always aim to water at the base of the plant early in the morning to allow foliage to dry out over the day, reducing the risk of fungal diseases.
LightGarden Cosmos thrives in full sun conditions where it can receive at least 6 to 8 hours of direct sunlight daily. The ideal spot for planting is in an open area away from the shade of trees or buildings to ensure the plant gets ample sunlight throughout the day, which is vital for prolific blooming.
TemperatureThe ideal temperature range for Garden Cosmos is between 70°F and 85°F. These flowers can survive minimal frost but prefer warmer climates. They can handle a minimum temperature of around 32°F; however, prolonged exposure to cold can damage or kill the plant. Ensure they are grown in conditions where temperatures do not frequently dip below the freezing point.
PruningPruning Garden Cosmos is chiefly for aesthetic purposes and to promote continuous blooming. Deadhead spent flowers regularly to encourage the plant to produce new blooms. Cut back the stems by 1/3 after the first flush of flowers to rejuvenate the plant for a new blooming cycle. The best time for more extensive pruning is mid- to late summer.
CleaningAs needed
SoilCosmos, commonly known as garden cosmos, thrives in a well-draining, loamy soil with a pH range of 6.0 to 8.5. The ideal soil mix for cosmos can be made by combining two parts garden soil, one part peat, and one part perlite or sand to ensure proper drainage. Organic compost can be added to supply nutrients.
RepottingThe Cosmos, or garden cosmos, typically doesn't require frequent repotting as it is often grown as an annual. Repotting can be done annually if grown in containers, preferably in the spring when starting new plants or when plant growth indicates the current pot is too small.

Life cycleCosmos Razzmatazz Series starts its life as a seed, typically sown after the last frost when the soil has warmed. Upon germination, the seedling emerges and begins to grow, developing true leaves and a root system. As the plant enters the vegetative stage, it forms a bushy structure with finely divided, feathery leaves characteristic of cosmos. Transitioning into the reproductive stage, it produces vibrant, double-flowered blossoms that attract pollinators such as bees and butterflies. After pollination, the flowers will fade, and the plant will set seeds, completing its life cycle. In temperate climates, Cosmos Razzmatazz is grown as an annual, dying with the first hard frost, whereas, in warmer regions, it may survive as a perennial if conditions allow.
PropogationPropogation time
Spring-Summer
Propogation: Cosmos, specifically the Cosmos bipinnatus Razzmatazz Series, is most popularly propagated through seeds. The ideal time to sow these seeds is after the last frost in spring to ensure that the seedlings are not exposed to detrimental cold temperatures. To propagate, prepare a well-draining soil mix in a flat or a pot and scatter the seeds on top, pressing them lightly into the soil. They need light to germinate, so they shouldn't be covered with soil, just pressed gently into the surface. Keep the soil moist but not saturated and in a warm spot with plenty of indirect sunlight. Germination typically occurs within 7-10 days. Once the seedlings have several sets of leaves and are sturdy enough, they can be transplanted into the garden spaced about 12 to 18 inches (approximately 30 to 45 centimeters) apart to allow for ample growth.
