Sunflower’s growth is directly related to sunlight! You can grow it in a home garden as sunflowers are heat-tolerant, resistant to pests, and beautiful. Seed harvesting is also possible from them. Here are a few tips: • Sunflowers grow best in locations with direct sunlight (6 to 8 hours per day). • The ideal pH level of soil should be 6.0 to 7.5 (slightly acidic to somewhat alkaline). • If possible, put seeds in a spot that is sheltered from strong winds, perhaps along with a fence or near a building. • For indoor bouquets, cut the main stem just before its flower bud. It creates a possibility to encourage side blooms.
