Water: After transplanting serbian spruce 'Nana', water 5-7 times every 5-7 days, using rooting powder to promote root growth. Keep soil moist but avoid standing water to prevent root rot. Water approximately every 10 days, adjusting frequency based on weather; increase if leaves droop.

Fertilize: Apply base fertilizers pre-transplanting for long-term nutrition for serbian spruce 'Nana'. In the first year, use nitrogen and phosphorus every 2 weeks; in fall, add potassium. After maturity, fertilize 2-4 times annually in spring and summer. Use organic fertilizers to enhance soil and growth, watering if soil dries.

Pruning: Serbian spruce 'Nana' has dense, slow-growing foliage and a compact habit. Prune dead or damaged branches and shape lightly in early to late winter. This enhances air circulation and light penetration, promoting health while reducing pest risk. Minimal cuts are recommended to avoid stress.

Propagation: Propagate serbian spruce 'Nana' by taking 10-20 cm cuttings from robust, year-old branches in summer. Dip in rooting solution and plant in sterilized, moist soil, spacing them 20-30 cm apart. Keep soil moist until rooted, then transplant outdoors by early spring the following year.
