If ingested, the plant could potentially cause mild gastrointestinal discomfort, nausea, vomiting, or diarrhea in sensitive individuals. The pollen might cause allergic reactions in susceptible persons. It is generally advisable to handle chrysanthemums with care and avoid ingestion to prevent any possible unpleasant reactions.

WaterPink Chrysanthemum prefers consistent moisture, so it should be watered when the top inch of soil feels dry. This usually equates to watering once every week, but this can vary depending on the climate and the time of year. During hot and dry periods, the plant may need more frequent watering, potentially every 2-3 days. Provide enough water to moisten the soil throughout the root zone, roughly equivalent to 1 gallon per watering for a medium-sized plant. In the cooler months or during rainfall, reduce watering to prevent waterlogged soil which can lead to root rot.
LightPink Chrysanthemum thrives in full sun to partial shade. Ideally, place the plant where it will receive at least 6 hours of direct sunlight daily. A spot that gets morning sun and afternoon shade is also beneficial, especially in regions where the sun is very strong. Too little light can result in a leggy plant with fewer flowers.
TemperaturePink Chrysanthemum does well in temperatures ranging from 60 to 75 degrees Fahrenheit but can tolerate a range from 32 to 95 degrees. It's particularly important to protect the plant from frost, which can damage the foliage and blooms. Ideally, provide a location that maintains a consistent temperature within the ideal range to encourage robust growth and flowering.
PruningPruning Pink Chrysanthemum is essential to promote bushier growth and more abundant blooms. Pinch back the tips of stems in late spring and early summer to encourage branching. Cut back the plant by one-third in early summer to stimulate fall flowering. After blooming, prune the foliage down to the ground once it has died back, typically after the first frost, to keep the plant tidy and healthy.
CleaningAs needed
SoilPink Chrysanthemum favors well-draining, fertile soil with a pH of around 6.0 to 7.0. A good soil mix for this plant would consist of equal parts loam, peat moss, and perlite or sand to ensure adequate drainage and aeration. Add compost to the mix to enrich the soil with nutrients.
RepottingThe Pink Chrysanthemum should be repotted every one to two years to refresh the soil and accommodate root growth. Repot in late winter or early spring before new growth starts, selecting a pot that's slightly larger than the previous one.
Humidity & MistingThe Pink Chrysanthemum prefers moderate humidity levels, ideally between 40% to 60%. While it can tolerate lower humidity, ensuring adequate levels will support healthy growth and vibrant blooms.

Life cyclePink Chrysanthemum (Chrysanthemum weyrichii) begins its life cycle with seed germination, which occurs in late winter or early spring under optimal temperature and moisture conditions. After germination, seedlings emerge and develop into young plants with a rosette of leaves at the soil surface. In spring to early summer, the plant enters a vegetative growth phase, producing stems, leaves, and eventually buds, as it matures. Flowering occurs in late summer to fall, showcasing the characteristic pink blooms that attract pollinators. After pollination, seeds are produced and dispersed, completing the reproductive cycle. As winter approaches, the plant may die back, especially in colder climates, but can also survive as a perennial, regenerating from the root system when conditions become favorable.
PropogationPropogation time
Spring-summer
Chrysanthemum weyrichii, commonly known as Pink Chrysanthemum, is best propagated through division, a method that allows gardeners to create new plants while rejuvenating the old ones. Division should be performed in early spring or after the blooming period in the fall when the plant is not in active growth. To propagate by division, gently dig up the clump of the Pink Chrysanthemum and use a sharp, clean knife to divide the root ball into sections, ensuring that each section has a good amount of roots and at least one or more shoot buds. The divisions should then be replanted immediately at the same depth they were growing before and watered thoroughly. This process not only multiplies your Pink Chrysanthemum plants but also encourages vigorous growth and abundant blooms in the following season.
