Only by checking the soil moisture meticulously every morning can I ensure the delicate sprout receives proper care.The seedling has now grown to 30 centimeters tall,with its stem becoming sturdier each day.What surprises me most is the way its young leaves unfold- each new pair takes on a distinctive spiral pattern,_enables me to witness nature's intricate design in detail. It is crucial that I keep track of its day-to-day changes in my observation journal.Just yester- day,the first flower bud emerged,showing signs of what will soon be a magnificent bloom. Under natural conditions,sunflowers typically take 60-90 days to mature,but my indoor plant seems to be accelerating its growth,possibly due to the warm temperature. Recording the duration of each growth stage,I've noticed that the plant evolves most dra- matically during the night.While most people sleep,the stem subtly bends towards the window,manifesting its natural phototropism.Although the flower hasn't reached full bloom yet,I already cherish these moments of watching life unfold. The more I observe this sunflower,the deeper my appreciation for nature's wonders grows. I look forward to documenting when it finally comes into existence as a fully bloomed flowef and I'll certainly pay close attention to how long its beauty will last before it begins to fade away.
