Pink, red, orange, yellow or white blooms open just as the garden’s other flowers grow scarce, and they keep going long after most borders have finished. Best known for adorning graves, the autumn daisy (Chrysanthemum) suits a bed, a pot or a garden box just as well: give it full sun and soil kept moist, and it flowers for weeks.

Planting autumn daisy
Autumn daisy is planted ideally in spring because even if it will only bloom at the end of summer or in fall, it will have developed a great root system and will resist the harshness of fall and winter much better.
Position the young plants in spring in soil that has been amended and that drains well.
Spring planting builds the roots that carry it through winter
Autumn daisy that has been purchased in pots in fall can be planted directly to the ground, to larger pots or garden boxes, preferably with soil mix but its hardiness won’t be as good.
You’re advised to find a sunny spot that will embellish the blooming.
Snip off withered stems before replanting it to the garden.
Water after planting.
Pruning, caring for and watering autumn daisy
Autumn daisy requires relatively little care, mostly only watering regularly when there’s no rainfall.
Removing wilted flowers brings on a fresh crop of blooms
Remove wilted flowers as they appear, since this increases production of new flowers.
Water when the soil is dry, especially if using a pot, because chrysanthemum call for moist soil to grow properly.
You should endeavor not to wet the leaves to avoid appearance of diseases such as rust or powdery mildew.
After the first frost spells, when flowers start to turn black, cut the stems back to ground level and cover with a thick cover of dried leaves.
Telling autumn daisy problems apart
