Water: Sawtooth goldenbush is adapted to arid environments, demonstrating excellent drought tolerance with minimal moisture needs. Watering every 2-3 weeks is sufficient. Thriving in full sun and well-draining soil, sawtooth goldenbush effectively utilizes scarce water resources, preventing root rot from excessive moisture.

Fertilize: For sawtooth goldenbush, apply high-nitrogen fertilizer 1-2 times in spring/early summer to enhance growth and flowering. Avoid over-fertilization and reduce feeding during dormancy. Handle fertilizer cautiously, keeping it away from sawtooth goldenbush's foliage, and adjust feeding schedules based on local climate.

Pruning: Sawtooth goldenbush is a hardy, sun-loving shrub with serrated leaves and yellow flowers. Light pruning in early to late winter encourages dense growth and prolongs flowering, while removing dead branches minimizes pests and promotes vigorous spring growth, enhancing health and appearance.

Propagation: Sawtooth goldenbush thrives in arid conditions and is best propagated through cuttings. Select vigorous stems and trim below a leaf node to enhance rooting. While rooting hormone aids the process, sawtooth goldenbush naturally roots well. Use a well-draining medium to mimic its native soil for optimal growth.
