They thrive in well-draining soil and in full sun, but they can handle part shade in hotter areas.
Nippon Daisy Care
This perennial is easy to grow in any sunny location with well-draining soil.
However, in hot climates, some afternoon shade is preferable.

It will tolerate most soil types as long as there is good drainage.
Soggy soil can kill the plant.
Water if your area has an extended period of drought and the plant starts to wilt.
The Spruce / Autumn Wood
Any abnormal temperature extremes within its growing zones can damage or kill the plant, though this is rare.
Frost will cause the plant to naturally die back to ground level for the winter.
But if you have very poor soil, you might use a balanced 10-10-10 fertilizer in the early spring.

Pruning
This plant doesn’t need much in the way of pruning.
For a bushy, upright growth habit, slightly cut back new growth in the spring.
But avoid pruning once flower buds have appeared.

Moreover, remove spent flowers throughout the summer to encourage the plant to continue blooming.
Division is best done in the spring every two to three years just as new growth begins.
Repot them when the roots start filling the pot and growing out of the drain holes.
Divide the clump into smaller sections like you would in-ground plants.
Container plants are more vulnerable, as their roots are exposed.
Common Plant Diseases
Serious pest and disease problems are rare with the Nippon daisy.
Also, verify the plants aren’t crowded and have good air circulation.
Be on the lookout for brown or black spots on the leaves and stems.
If the disease is severe, an all-purpose fungicide can be applied.
Bloom Months
Nippon daisies are fall bloomers, producing flowers in September and October.
What Do Nippon Daisies Look and Smell Like?
Nippon daisy flowers are about two to three inches wide, with white petals and yellow centers.
They offer a bit of a musky smell that is disliked by some.
Nippon daisies need full sun to bloom.
Next spring, give them a bloom-boosting fertilizer that is high in phosphorous.
This is a natural process as the plant gets ready to enter dormancy in the fall.
Instead, plant Nippon daisies in the back of a flower bed where the bare stems are less obvious.
The daisies are very hardy, and once established, they remain and spread.
However, they are not listed as invasive.
