Water: Coast sandbur, adapted to arid environments, excels in drought tolerance and requires weekly watering. Typically found in sandy soils, it suits xeriscaping and endures dry spells due to its robust root system that efficiently absorbs moisture.

Fertilize: For coast sandbur, use a balanced fertilizer during spring and summer every 4-6 weeks. Opt for higher nitrogen for early leafy growth. Reduce fertilization in fall and winter, ensuring thorough watering when applying nutrients to prevent root burn and support resilience.

Pruning: Coast sandbur prefers sandy soils and coastal regions, requiring early to late spring pruning to foster healthy growth, eliminate dead stems, and control spread. Clean tools are essential to prevent disease. Pruning promotes denser foliage and enhances resilience, resulting in a more attractive appearance.

Propagation: Coast sandbur is a hardy perennial that thrives in sandy coastal soils. For successful propagation, use well-draining sandy substrates and space seeds adequately. Maintain consistent moisture until germination, then reduce watering to promote robust root development for effective cultivation.
