Growth Rate

Known for its rapid growth rate, little sunflower exhibits an impressive surge during Spring and Summer, the capped apexes furiously sprouting leaves and blossoms, enhancing its photosynthetic potential. Its rapid growth allows for remarkable vertical ascent, contributing profoundly to its survival strategy. This pattern, while prevalent during Spring, is markedly escalated in Summer's increased daylight, offering a fascinating study in adaptive horticulture.

Water: Little sunflower prefers consistently moist soil and thrives with weekly watering, reflecting its native environment's regular rainfall. Typically grown outdoors, it adapts well to seasonal wet and dry patterns, making it a robust choice for gardens experiencing varying moisture levels.

Fertilize: Little sunflower thrives with balanced fertilizers (N-P-K) applied every 4-6 weeks during growth. Fertilize sparingly to avoid nutrient burn, reducing frequency in fall and winter. Ensure soil is moist and integrate or distribute fertilizer evenly for vibrant blooms.

Pruning: Little sunflower features bright yellow flowers and lanceolate leaves. Prune in early to late spring for denser growth and more blooms. Remove dead stems and shape overgrown areas by cutting to a healthy node, using clean tools to prevent disease.

Propagation: Little sunflower features daisy-like flowers and is propagated by sowing seeds in well-draining soil. Seeds need light covering and moisture until germination in 2-3 weeks. Young plants require ample sunlight and proper spacing, while avoiding waterlogged conditions to prevent root decay.
