Narrowleaf zinnia requires bright, direct sunlight for optimal growth. It prefers moderate temperatures and can tolerate dry conditions. Regular watering is necessary, but the soil should be allowed to dry out between waterings. It thrives in moderate humidity levels.
土壌
Zinnia angustifolia prefers well-draining loam soil. It can tolerate a range of soil types but performs best in soil that is not too rich in nutrients. Good drainage is essential to prevent root rot.
肥料
A balanced fertilizer with an N-P-K ratio of 10-10-10 can be applied once a month during the growing season. Over-fertilizing should be avoided as it can lead to excessive foliage growth at the expense of flowers.

Propagation is typically done through seeds. Seeds can be sown directly in the garden after the last frost or started indoors 4-6 weeks before the last frost date. Ensure the soil is warm and well-draining.
剪定
Pruning is not generally required for Zinnia angustifolia. However, deadheading spent flowers can encourage more blooms and keep the plant looking tidy.
