Transplantation: After the sunflower sprouts have grown five true leaves, transplantation can begin. Prepare a larger flowerpot in advance, and choose slightly acidic to neutral sandy soil with good drainage and breathability. And apply some compost to increase the nutrients in the soil. After the pot soil is ready, you can plant the small seedlings of sunflowers into the flower pot. After planting, place it in a well ventilated area without sunlight, and wait for it to stabilize before placing it in a sunny area. If well maintained, it will take about fifty to sixty days to bloom
